Software Engineer - AI Agents

Zapp

<div><p><b>Principal Software Engineer, Mobile (React Native)</b></p><p>
Nine Elms, London - Full-time (4 days a week on-site)</p><p><b>
About Zapp</b></p><p>
Zapp is London&rsquo;s leading premium convenience retail platform. Founded in 2020, our vision is to disrupt the multi-trillion dollar convenience retail market, currently dominated by major players, by developing best-in-class customer-centric technology and fulfilment solutions. Zapp partners with some of the world&rsquo;s leading brands to deliver an exclusive range of hand-picked products 24/7, delivered in minutes.</p><p>
Quick commerce is a genuinely hard mobile problem. Stock changes by the second, orders and riders move in real time, and we make sub-minute promises we have to keep, all on patchy high-street connections across a huge range of devices. Getting that right, fast and reliably, is the job.</p><p>
We are serious about AI, as a way of working rather than a slogan. AI-assisted development is part of the daily toolkit here, and we ship LLM-powered features where they genuinely make the product better.</p><p><b>
The Role</b></p><p>
As Principal Mobile Engineer you own the technical direction of our consumer iOS, Android and web apps, all built on React Native. This is a deliberately hands-on Principal role. You set the architecture and the standards, and you are still in the code every week shipping the hardest parts yourself. You will be the most senior mobile engineer in the company and the person the rest of the team levels up against.</p><p>
You will work closely with stakeholders in Commercial, Marketing and Operations to shape what we build and make sure the app serves the whole business.</p><p><b>
What you'll do</b></p><ul><li><p>
Own the architecture of the React Native app across iOS, Android and web, and make the calls on patterns, tooling and technical direction</p></li><li><p>
Stay hands-on: ship the hardest features yourself and set the standard for what good looks like in the codebase</p></li><li><p>
Raise the engineering bar across the mobile team through sharp code review, mentoring, and the example you set</p></li><li><p>
Drive performance, stability and responsiveness, profiling and fixing the things that actually hurt on real devices and real networks</p></li><li><p>
Own the release process and the health of what we put in front of customers</p></li><li><p>
Partner with the wider business and the leadership team to turn ideas into fast, reliable, polished experiences</p></li><li><p>
Work across the stack where it helps, into the backend APIs and data layers that feed the app</p></li><li><p>
Use AI tooling (Claude, Cursor, Copilot) to ship faster and help the team get genuinely good at it, and build AI-powered features with LLM and on-device capabilities where they improve the product</p></li></ul><p><b>
What you'll bring</b></p><p>
Essentials</p><ul><li><p>
A track record of building and shipping B2C consumer mobile apps at scale, and being the person who sets technical direction for a mobile team</p></li><li><p>
Deep React Native expertise across iOS and Android, with the judgement to know its limits and drop into native when needed</p></li><li><p>
Strong TypeScript</p></li><li><p>
Real command of mobile performance, stability and release processes</p></li><li><p>
Solid grasp of mobile security: secure storage, authentication patterns, and API security</p></li><li><p>
You take genuine end-to-end ownership and operate autonomously</p></li><li><p>
You communicate clearly, in writing and in person, and can bring people with you on a technical call rather than just winning the argument</p></li></ul><p>
You have probably been doing this for 7 or more years, but we care about the impact you have had, not the number on your CV.</p><p>
Nice to have</p><ul><li><p>
Node.js (Express, Fastify) for the API layer</p></li><li><p>
React.js or React Native for Web</p></li><li><p>
Native experience (Kotlin, Swift) for the bridge and the trickier native modules</p></li><li><p>
GraphQL, GCP, Firestore, Event-Driven architecture</p></li><li><p>
Hands-on experience building with LLM or AI APIs</p></li></ul><p><b>
Benefits</b></p><ul><li><p>
Competitive salary, plus meaningful equity</p></li><li><p>
25 days holiday, plus all bank holidays</p></li><li><p>

Lottie

<div><p><b>Title: </b>Senior Growth Engineer</p><p>
<b>Department:</b> Engineering</p><p>
<b>Salary: </b>&pound;75,000 - &pound;95,000</p><p>
Benefits &amp; Culture: Lottie&rsquo;s careers page here, Lottie&rsquo;s tech careers page here</p><p>
Meet our CTPO: Solving hard problems in care</p><p>
<b>Equity: </b>A very generous EMI share offering.</p><p>
<b>Holiday: </b>26 days + bank holidays.</p><p><b>
Mission:</b> Elevate later life for everybody and build the care sector of the future.</p><p>
<b>Office Policy:</b> Hybrid with a two core office days per week.</p><p>
<b>Office Location:</b> London Bridge, London, UK</p><p></p><h1 class="jobSectionHeader"><b>
</b><b>The Opportunity:</b></h1><p>
Lottie's marketplace connects millions of families with the right care at the right time. We've built something real - now we need to grow it faster, smarter, and with more precision than a traditional engineering team can.</p><p>
We're looking for a <b>Senior Growth Engineer </b>to join a small, focused Marketplace team and own the full experiment loop - from hypothesis to code to result. You'll work closely with a PM and designer to run high-velocity tests, feed signal back to Google to sharpen our ad performance, and build the lightweight tooling that lets us learn faster than our competitors.</p><p>
This is a role for someone who ships first, learns fast, and doesn't look back. If you need things to be perfect before they go live, this probably isn't the right fit.</p><p></p><h1 class="jobSectionHeader"><b>
What does this role involve?</b></h1><ul><li><p><b>
Running end-to-end experiments across Lottie's marketplace</b>, from ideation through implementation to result analysis</p></li><li><p><b>
Building and optimising conversion-focused front-end experiences</b>, often with limited design input</p></li><li><p>
Writing code that sends performance data back to Google to improve ad targeting and campaign efficiency</p></li><li><p><b>
Automating parts of our Google Ads</b> configuration and campaign management</p></li><li><p><b>
Owning A/B test pipelines and iterating quickly</b> based on real usage data</p></li><li><p>
Working autonomously within a lean, fast team</p></li></ul><p></p><h1 class="jobSectionHeader"><b>
What problems will you be solving?</b></h1><ul><li><p><b>
Turning traffic into outcomes.</b> Our marketplace is trusted by half a million families a month. You'll be closing the gap between the families who land on Lottie and the ones who find the right care. Every experiment you run is a chance to make that faster, clearer, and more effective.</p></li><li><p><b>
Making our ad spend smarter. </b>You'll build the pipelines and integrations that help Google understand what a good Lottie outcome looks like, so our campaigns optimise toward the things that actually matter.</p></li><li><p><b>
Moving fast in a space that matters.</b> Care decisions are urgent and emotionally charged. Getting families to the right information faster isn't just a conversion metric. It's a meaningful outcome for real people.</p></li></ul><p></p><h1 class="jobSectionHeader"><b>
We think you&rsquo;ll be a great fit if&hellip;</b></h1><ul><li><p>
You have<b> 5+ years of software engineering experience, front-end leaning with genuine full-stack breadth</b></p></li><li><p><b>
You think in experiments. You can articulate what </b><b><i>moved</i></b><b> because of your work,</b> not just what you built</p></li><li><p>
You're comfortable with throwaway work. When a test fails, you kill it and move on</p></li><li><p>
You're <b>autonomous and low-dependency</b>. You thrive with a hypothesis and a deadline, not a detailed spec</p></li><li><p>
You're <b>data-driven.</b> You define success before you build, and you look at the numbers before you declare a win</p></li><li><p>
AI tools like Claude Code are already a big part of how you work, and you&rsquo;re hungry to get better at them</p></li></ul><p><i>
Sound like you but not quite 100%? Apply anyway - we're looking for potential and passion, not perfect CV match!</i></p><p></p><h1 class="jobSectionHeader"><b>
This role isn&rsquo;t for you if&hellip;</b></h1><ul><li><p><b>
You prefer depth over breadth </b>and one big build over many small bets</p></li><li><p>
You need clearly scoped requirements before you can move</p></li><li><p><b>
You're looking for a team with lots of process and structure around you</b></p></li><li><p>
Our mission to transform later life care doesn't resonate with you</p></li></ul><p></p><h1 class="jobSectionHeader"><b>
