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">

Senior Backend Engineer

Zoopla

<div>Who We Are
Zoopla is one of the UK&rsquo;s most instantly recognisable property brands. In fact, we&rsquo;re known and loved by over 91% of the nation (and we&rsquo;re working hard on the other 9%). Our mission is to help the nation make better home decisions - by connecting everyone to their home and giving them personalised insights to help with moving, managing or financing. Over 50 million people visit Zoopla every month to access exclusive data and information on every UK property, search over 500,000 homes for sale and rent, find the best agents and secure the latest mortgage deals.
We&rsquo;re a growing, dynamic team that embraces innovation and isn&rsquo;t afraid to push the boundaries. We&rsquo;re only just starting our journey to redefine the digital property landscape, with much more to explore and achieve. Join us, and transform the way the nation makes home decisions.
What You'll Do
At Zoopla you will design and run the search and retrieval systems behind the consumer portal, serving millions of users. Search relevance, ranking, and the services and data pipelines that feed them sit at the centre of this role. If you care about robust APIs, fast and relevant search, scalable distributed services, observability, and personalisation, this is for you.
You will work primarily in Python and TypeScript across Node.js and GraphQL, with some services in Golang or Perl. You will own search infrastructure end to end on OpenSearch (or Elasticsearch): indexing, query design, relevance tuning, and performance at scale. You will design and maintain the APIs and data pipelines that power it, working across both SQL and NoSQL stores on AWS.
This is a backend role. You will touch the frontend (React and TypeScript) occasionally when a feature needs it, but deep frontend specialism is not expected.
Requirements (all essential)<ul><li>
Senior engineer who has built and operated high scale systems serving millions of users, and who can point to the trade offs they made to get there.</li><li>
Production experience with OpenSearch or Elasticsearch: indexing strategy, query and relevance tuning, and keeping clusters healthy under load.</li><li>
Strong distributed systems and systems design skills, with the ability to reason about consistency, latency, failure modes, and scale.</li><li>
Hands on AWS experience running services in production.</li><li>
Fluency in backend development with Python and TypeScript, designing and building APIs and services across SQL and NoSQL stores.</li><li>
A genuine passion for shipping product features with a high level of autonomy and agency, taking an idea from problem to production with minimal hand holding.</li><li>
Excellent communication skills and a track record of working closely with Product and Design to turn ambiguous goals into shipped features.</li></ul>
Also valued<ul><li>
Solid engineering craft: maintainable code, code review, pairing when it helps, and meaningful tests.</li><li>
Building for stability, security, observability, and performance, not just the happy path.</li><li>
A commercial mindset that connects your work to business outcomes.</li><li>
You use AI tools as a core part of how you build, from coding assistants to AI driven workflows, and you have a strong sense of where they speed you up and where they need checking.</li></ul>
Where you&rsquo;ll be
At Zoopla, we embrace hybrid working but emphasise the importance of also spending time together. You&rsquo;ll have the opportunity to work remotely (at home) for two days per week with Mondays and Thursdays as all-Zoopla days in the office together plus a third day in-office day of your choosing.
Our home in Tower Bridge is a buzzing hub for collaborative and individual working, with areas to socialise and exercise - within easy reach of London Bridge, Tower Hill and Bermondsey stations. On our doorstep there are plenty of great food spots including a new indoor street food market and landscaped areas to sit by the riverside. 
Benefits 
<ul><li>
Our hybrid setup means you&rsquo;ll join us in the Tower Bridge office 3 days each week</li><li>
25 days annual leave + additional leave benefits Including extra days for length of service, plus other leave perks</li><li>
Cycle to work and electric car schemes</li><li>
Free Calm App membership</li><li>
Enhanced Parental leave</li><li>
Fertility Treatment Financial Support</li><li>
Group Income Protection and private medical insurance</li><li>
Gym on-site in London</li><li>
7.5% pension contribution by the company</li><li>
Discretionary annual bonus up to 10% of base salary</li></ul></div>

Software Engineer

Ravio

<div>We help companies get compensation right.
What we get paid at work has a massive impact on our lives, and it&rsquo;s one of the biggest factors in hiring and retaining talent - and yet so many companies struggle to get it right. They simply have no choice but to rely on poor data and unsophisticated tools for their pay decisions. That&rsquo;s why we created Ravio.
We help many of the world&rsquo;s most innovative and ambitious companies build stronger teams and reach their goals through better compensation. Our real-time data platform brings compensation into the modern age, tracking the market across all compensation types from salary to equity and benefits.
Ravio is growing fast, which means you can too. We&rsquo;ve established ourselves as the European leader in our space serving more than 1,200 clients, and now have our sights set on becoming the global go to place for compensation data and tools for managing compensation.
Joining a startup and scaling it into a global product is one of the most challenging and rewarding experiences a career can offer. If that sounds exciting to you, you&rsquo;re in the right place. 
The role
We&rsquo;re looking for a Lead Software Engineer to join our engineering team and play a major role in our technical leadership during a significant platform shift.
Ravio is moving from a traditional SaaS posture to a platform built around agents - parent agents fronting our compensation data, specialist agents underneath, durable workflows, an MCP-based tool layer, and an eval harness to maintain consistency. You&rsquo;ll own architecture and technical design across the stack: the customer-facing web app, the agentic platform, and the shared infrastructure connecting them.
You&rsquo;ll bring system design depth - the kind that holds up under load, failure, and coordination across services and teams. You&rsquo;ll continue to raise the bar on code quality, reliability, and the technical decisions that shape what we ship.
This is a hands-on individual contributor role - leading technical decision-making and tackling the hardest problems we encounter. There are also upcoming opportunities to move into management as our company continues to grow, if you wish. 
Requirements<ul><li>
8+ years commercial engineering experience, with a track record of technical leadership during platform shifts - owning architecture, driving decisions, raising the bar through code review and design review, especially where LLM assisted engineering has become the standard</li><li>
System design depth as your headline strength. Concrete: durability and consistency under failure, multi-service orchestration, data platforms, performance and cost at scale, observability and ops fluency</li><li>
Senior-level fluency in TypeScript and Node, comfortable across the backend (PostgreSQL, GraphQL or HTTP APIs, GCP-shaped infra)</li><li>
Comfortable owning code in a distributed monorepo with multiple deployable services</li><li>
Ships fast under product pressure - we&rsquo;re moving from PMF to scale and the role needs that pace</li></ul>
Nice to have<ul><li>
Production experience with agentic systems - tool calling, multi-step orchestration, LLM evals.</li><li>
Workflow engines (Temporal, Cadence, Step Functions) - even if not Temporal specifically</li><li>
MCP, Anthropic SDK, or other LLM platform work</li><li>
Building developer platforms, internal SDKs, or framework-shaped surfaces</li><li>

The opportunity at Ravio right now
From your perspective, there are three critical things to look for when evaluating this role: a company going places, a strong engineering culture, and a role that gives you a true opportunity to have impact as a technical leader.
Ultimately it&rsquo;s for you to decide whether that&rsquo;s true in our two-way street interview process. Here&rsquo;s a summary of where we are right now and what you can expect as a starting point.
There&rsquo;s a lot happening at Ravio right now. We&rsquo;ve just raised our Series A led by tier 1 US investors Spark Capital, and have acquired the benchmarking business of our competitor - Compete. We&rsquo;ve got new joiners starting almost every week, and we&rsquo;re rapidly expanding outside of our core markets in Europe. We need you to help us maintain our velocity and continue to build a scalable org and product.
Our core benchmarking product is at product-market fit, and we have a couple of new modules in the 0-1 phase. This means we&rsquo;re at an exciting stage that involves 0-to-1 building in some areas, and building for scale in others. That&rsquo;s true across the business, we&rsquo;re continuing to expand and experiment, while systemising and doubling down on what is already working well from our seed phase.
Beyond the core product, we&rsquo;re building Ravio&rsquo;s agentic platform - parent agents fronting our compensation data with specialist agents underneath, durable workflows on Temporal, an MCP-based tool layer, and an eval harness to maintain consistency. It&rsquo;s a platform engineering effort with the same care and rigour we apply to the rest of the product. A Lead engineer joining now would help shape the foundations of how Ravio&rsquo;s product is built for the next phase.
We&rsquo;d like to think Ravio is a great place to be a Lead engineer - we have technical leaders who know first hand the importance of creating space and focus for engineering teams to do their best work. And you&rsquo;ll be working alongside many accomplished and world class teammates, who are energised by the work they do and have a high bar for themselves and their colleagues.

Shape an agentic platform from its early stages, with senior engineering peers and a high autonomy bar.</li><li>
Opportunity for fast-tracked professional growth at a scaleup backed by world-class investors alongside a smart, energetic team.</li><li>
