Software Engineer III- JPM Personal Investing- Mid Level

Zapp

<div>Principal Software Engineer, Backend
Nine Elms, London. Full time (4 Days Onsite)
You'll need the right to work in the UK and be based in London. We are not able to offer visa sponsorship for this role.
About Zapp
We deliver the essentials in minutes, 24/7, from our own network of stores. Every order is a real-time race against the clock, and the systems that win it are the backend you would own.
Quick commerce is a genuinely hard backend problem. Stock changes by the second, orders and riders move in real time, and we make sub-minute promises we have to keep, at high throughput with no room for downtime. Getting that right, fast and reliably, is the job.
We're AI-first and we mean it as a way of working, not a slogan: AI-assisted development is part of the daily toolkit, we ship LLM-powered features where they genuinely earn their place, and we expect every engineer to shape how we use it.
Backed by the world's leading investors, built by people who've scaled Amazon, Deliveroo, Tesco, Just Eat and Stuart.
Our Leadership Principles
These five principles describe what great looks like at Zapp. They are the single framework we use across performance reviews, growth conversations, and leadership expectations.<ul><li>
Creating Magic</li><li>
Taking Ownership</li><li>
Raising the Bar</li><li>
Winning Together</li><li>
Delivering with Speed</li></ul>
The role
You'll be the most senior backend engineer at Zapp, owning the technical direction of the services that run the business, from ordering and inventory to logistics and the platform underneath. This is a hands-on Principal role: you set the architecture and the standard, and you're still in the code every week shipping the hardest parts yourself.
You'll work across the whole backend rather than one corner of it, going where the hardest problem is. You'll take ownership from a rough problem all the way to production and on-call, and you'll lift the engineers around you while you do it. When the team needs a pattern set, a hard call made, or the gnarly bit untangled, that's you.
What you'll do<ul><li>
Set the technical direction. Own the architecture of the backend across services, and make the calls on patterns, boundaries and tooling that the rest of the team builds on.</li><li>
Build the hard parts yourself. Design and ship the services, APIs and data models behind ordering, inventory and logistics, and set the standard for what good looks like.</li><li>
Raise the bar. Lift the engineers around you through design review, pairing, and the standard you set, and leave the team stronger than you found it.</li><li>
Own reliability and scale. Keep high-throughput, real-time systems fast and available, and design for the failure modes that come with sub-minute delivery.</li><li>
Own delivery end-to-end. Pick up a problem, design the solution, ship it to production, and be on the on-call rotation that stands behind it.</li><li>
Bring AI into how we build. Use AI in your daily work, share the patterns that help the team move faster, and learn from what others discover.</li><li>
Help shape AI in our product. Build the backend behind LLM-powered features, from the data and APIs to the guardrails that keep them safe in production.</li><li>
Work across the boundary. Partner with mobile, data and ops engineers on the contracts and systems that tie the product together.</li></ul>
You're a great fit if you<ul><li>
Experienced. 7+ years building backend systems in production, with real scale behind you.</li><li>
Strong in TypeScript. It's core to our backend and you're genuinely fluent, not just passing through.</li><li>
Polyglot. You've shipped production code in more than one language and reach for the right tool for the job.</li><li>
Distributed systems depth. You design services, APIs and data models that hold up under real-time, high-throughput load.</li><li>
Own the data layer. Confident with relational and non-relational stores, and clear on the trade-offs between them.</li><li>
Lead without a title. You set technical direction and bring people with you through clarity and example, not authority.</li><li>
Production minded. Reliability, observability, performance and security are things you design in from the start, not bolt on after the incident.</li><li>
Comfortable in uncertainty. You move forward when the path isn't clear, instead of waiting for someone to define it.</li><li>
Test as you build. Automated tests are how you ship code you trust.</li><li>
Pragmatic about delivery. You measure your work by what shipped and held up, not the elegance of the design doc.</li><li>
Excellent communicator. Clear in how you write and speak, and you love sharing what you learn.</li></ul>
If most of these land for you, please apply. We hire on trajectory and curiosity as much as CV.
Even better if you know<ul><li>
GCP. We run on Google Cloud, with Cloud Run, Pub/Sub and Firestore, so familiarity helps you hit the ground running.</li><li>
NestJS. Our TypeScript services are built on it.</li><li>
GraphQL. We run a federated gateway across multiple subgraphs, so federation experience makes schema and subgraph work easier.</li><li>
Event-driven architecture. Queues, streams and async messaging at scale.</li><li>
Infrastructure as code and DevOps. You're comfortable owning the path to production, not just the code.</li><li>
Quick commerce or similar domain. Logistics, on-demand delivery, or another real-time, high-throughput consumer environment.</li></ul>
You won't be a great fit if you<ul><li>
Need a fully defined process and a large, structured team to do your best work.</li><li>
Chase architectural purity at the expense of what the business actually needs.</li><li>
Stall when the path forward isn't clear, or wait to be told what to do.</li><li>
Want to stay strictly inside one service or specialty and avoid the rest of the stack.</li></ul>
What's the interview process like?
We aim to make our process clear, respectful of your time, and a real two-way conversation.<ul><li>
Stage 1 - Intro call (30 min). A short chat about your background and a chance for us to tell you more about Zapp, the team, and the role.</li><li>
Stage 2 - Technical interview (90 min). Live coding and a system design discussion. You'll have full access to any AI tooling you'd normally use, and we'll send you a boilerplate repository in advance so you can focus on the problem, not the setup.</li><li>
Stage 3 - Values &amp; Leadership interview (60 min). A conversation with senior leadership about how you work, what you care about, and how you align with our Leadership Principles.</li><li>
Stage 4 - Offer.</li></ul>
We will need to verify your right to work in the UK before extending an offer.
Benefits<ul><li>
Generous salary &amp; equity package</li><li>
25 days holiday per year, plus all bank holidays</li><li>
Private health insurance</li><li>
Extended sick pay and enhanced maternity and paternity leave</li><li>
Cycle to work scheme</li><li>
Pension (auto-enrolment)</li><li>
Budget for learning, conferences and kit</li></ul></div>

Harmonic Security

<div>AI is being run everywhere, by humans and agents. Harmonic Security governs all of it. The AI Governance and Control (AIGC) platform understands user / agent intent and data context in real time, giving security teams visibility and control across every tool and workflow so companies can move faster with AI while minimizing risk.
We operate in one of the fastest-moving spaces in tech: the emerging intersection of AI and cybersecurity. It's a market still being defined, and we're among the first to build natively for it - protecting sensitive data in real time, at the endpoint, with minimal friction for the teams using it. Enterprises get full visibility and control. Their people get to innovate without guardrails slowing them down.
Named to the Rising in Cyber 2026 list, Harmonic is gaining serious recognition and serious traction. We're led by deep cybersecurity expertise and backed by investors who know the space: N47, Ten Eleven Ventures, and In-Q-Tel.
As AI adoption inside the enterprise accelerates, the ability to safely observe, control, and enforce policy in real time isn't a nice-to-have. It's mission-critical infrastructure. That's what we build.<h2 class="jobSectionHeader">
How We Work: AI-First by Design</h2>
Harmonic exists to help enterprises adopt AI safely and at scale. We hold ourselves to that same standard. Everyone here actively leverages AI tools to perform their best work &mdash; from deep research and writing to building robust processes and automating complex workflows. We expect every new hire to bring a genuine curiosity for AI and a commitment to using it to work smarter, faster, and with greater creativity.
For some, this involves tinkering and remaining open to emerging tools; for others, it means architecting entirely new systems with AI at the core. We will be transparent about expectations for every role and provide the tools and support needed for you to thrive.<h2 class="jobSectionHeader">
About the Team</h2>
Our Product Delivery team is the engine that turns vision into impact. We ship early and often, getting valuable features into the hands of customers quickly and iterating from there. We work in the open by default, sharing progress and ideas, and we trust each other to own outcomes. We&rsquo;re a small but mighty crew where every person plays a critical role and we&rsquo;re committed to using AI to work smarter and faster.<h2 class="jobSectionHeader">
About the Role</h2>
We&rsquo;re looking for a Backend Engineer who has an appreciation for all things security and system interconnectivity.

Senior Backend Engineer

Tabeo

<div>Our mission is to become the financial and revenue operating system for primary care practices.
We help dental and veterinary clinics manage how money flows into the practice - from patient access, to payments, memberships, financing, insurance, and reporting - in one coherent system.
Rather than treating payments, plans, and finance as separate tools, we combine them into a single operating layer that reflects how practices actually run their business.
There are three structural shifts reshaping primary care right now:<ul><li>
Patient access is moving beyond opening hours. Clinics are under pressure to be available when patients want to engage, not just when the front desk is staffed. Voice and chat interfaces are becoming the new front door to care.</li><li>
Revenue is becoming structured, not ad-hoc. Memberships, financing, and insurance are increasingly used to smooth cashflow, improve access, and increase predictability &mdash; particularly as NHS capacity declines and private care expands.</li><li>
Practices need better financial insight, not more software. Owners and managers want to understand whether their pricing, plans, and utilisation make economic sense &mdash; without becoming analysts or relying on opaque tools.</li></ul>
Today, we support over 6,000 dental practices across the UK. 100 more join our platform every month. Tabeo is the dominant market leader for patient finance and seeks to reinvent memberships next. Beyond payments, we are launching a voice/chat AI solution that complements our existing products.
Tabeo is profitable. We seek to grow revenue by 50-60% per year and exceed &pound;25 million ARR in 2028.
We believe in a remote first approach to work and equip teams with perks and tools so they can thrive. However, we all come together 2x per year for our amazing &lsquo;Team Weeks&rsquo;. We previously met in Dubai, Lisbon, London and Athens. Next is a surprise!
About the role:
We&rsquo;re looking for an experienced backend engineer to join us! We currently have two cross-functional product teams. We&rsquo;re ambitious, and have many interesting strategic and technical challenges ahead of us, including:<ul><li>
Working towards our multi-product strategy as we scale our, Plans product</li><li>
Releasing our newest AI Revenue Engine product which is integrated across our product suite and provides multiple communication channels including voice, email, whatsapp and chat</li><li>
Expanding our target audience to include other primary healthcare providers (like vets and hearing specialists) and other regions/countries such as Germany.</li></ul>
Our legacy Finance system has supported us for 8 years and enabled us to reach &gt;10k dentists and create a sustainable, profitable business as we rapidly scale further. You should expect to play a key role in our engineering team:
We typically use the following tools and technologies:<ul><li>
Go to write our application code</li><li>
Google Cloud and AWS for infrastructure</li><li>
Confluent Kafka for our events handling</li><li>
Serverless technologies in AWS e.g. API GW, Lambda, EventBridge, DynamoDB, Docker for our new infrastructure</li><li>
Postgres for our databases</li><li>
Our frontend uses Javascript and TypeScript and is hosted on Vercel</li></ul>
Our interview process includes:
You&rsquo;ll start by having an initial call with our recruiter. From there, the process has three main stages:<ul><li>
A take home task (should take no more than 2 hours) or provide a sample from a public github we can discuss</li><li>
A technical interview with our engineering team</li><li>
A behavioural interview with our product team</li></ul>
As part of the process, we also ask candidates to complete a short critical thinking assessment in their own time. We use this as a benchmark alongside the interviews. It should take no longer than 40 minutes to complete.
If we extend you an offer, we&rsquo;ll also arrange for you to meet Paul, our CEO, where you can ask any outstanding questions you have about Tabeo. 
Requirements:<ul><li>
You have strong experience working on a Go backend of a technology product, particularly if you&rsquo;ve worked with Go or in fintech before</li><li>
You&rsquo;re comfortable working with a DevOps mentality of &ldquo;you build it, you run it&rdquo;</li><li>
You have a product mindset: you care about customer outcomes and you want to make data-informed decisions</li><li>
You&rsquo;re comfortable leading on projects that are large in scope, ambiguous, or not well defined</li><li>
You&rsquo;re the kind of person that cares about their team, and works to continuously improve culture, processes and communication.</li></ul>

By combining world-class tech with brilliant humans who care deeply about customers and driving the renewable energy transition, we made it happen and in 2025, we became Britain&rsquo;s largest energy supplier.
 
 
Now, we&rsquo;re scaling our services business, making it easy to switch to heat pumps, solar and EVs, and launching smart tariffs for Low Carbon Tech. 
 
With this, we&rsquo;re also taking the learnings, products and experiences that customers love here and rolling them out worldwide. 
 
OE Tech is the engineering and product organisation inside Octopus Energy. Here you&rsquo;ll have real ownership, variety, and the chance to shape products that make a tangible difference in people&rsquo;s lives: lowering bills, enabling greener living, and delivering experiences customers genuinely love. You&rsquo;ll work side by side with teams across services, marketing, operations, and data, and see the impact of your work in the real world, fast. 
 
We are looking for a Senior Backend Engineer to join our Low Carbon Tech team. 
 
We are installing EV Chargers, Solar, Batteries and Heat Pumps into homes to drive the energy transition at pace. As customer demand grows, our goal is to ensure scaling up never means slowing down or compromising on a world-class customer journey for low carbon tech.
 
 
To make that happen, we are building a new, dedicated engineering and product team to completely re-imagine this process - making it fast, transparent, and predictable for our customers from day one. This will be a small multi-disciplinary team who&rsquo;ll sit within our much bigger low carbon tech team.
 
 
You&rsquo;ll help design and build the platform architecture, data integrations, and automations that eliminate real world friction. If you want to design and build solutions to scale up electrotech in the nation&rsquo;s homes, this is the mission for you.
 
 
We embrace flat hierarchies and an open, agile culture that fosters innovation, flexibility, and creativity. We don&rsquo;t hang our personalities up with our coats and nor should you.
 
 
At Octopus, we hire great people who get stuff done, all whilst being themselves.

What you'll do...</h3><ul>
<li>Take total technical ownership of key platform components, shaping direction and bringing clarity to ambiguous problems while ensuring solutions are well-designed, scalable, and maintainable.</li>
<li>
Consistently write production-ready, self-documenting code that requires minimal revision, and actively improve testing strategies, non-functional requirements (performance, security, scale), and test infrastructure.
</li>
<li>Tackle systemic bottlenecks and architectural risks across multi-service configurations before they hit production, utilising highly systematic debugging approaches.
</li>
<li>Mentor other engineers, lead technical discussions, and perform rigorous code reviews to leave our systems, practices, and people stronger than you found them. Your influence will go far beyond your own delivery to help make Octopus an incredible place to be an engineer.
