Mobile Developer

We’re a small, autonomous mobile team working on what we think is the best PropTech app on the market. There’s no micromanagement and no fixed sprint rituals: when a new project kicks off we get together as a “three amigos” with product and design, get the first tickets out, then keep the conversation going as the work develops. You’ll have dedicated backend, design and product colleagues alongside you, and full freedom over how you work.

If you love autonomy, are naturally curious, and want to have a genuine impact within a growing company, we think you’d fit right in!

Here’s what you can expect to be working on as a Mobile Developer (L5) at Street Group

• Owning the end-to-end delivery of significant features in our React Native app: scoping the problem, directing the build, testing, shipping and iterating based on what you learn.
• Directing agent sessions to deliver work, while your own attention goes on the user experience, platform feel and the decisions where your judgement is required.
• Making every experience feel natural on both iOS and Android - understanding what users on each platform expect, and building for it.
• Looking after the live app: monitoring, stability and our weekly releases across the App Store and Google Play.
• Defining what success looks like before you build, analysing how features perform after release, and proactively bringing the results - good or bad, backed by data - to product and design.
• Being a regular voice in product discussions: taking a loose “what if we…” idea and turning it into a strong first version.
• Picking up tech debt and spotting improvements alongside your main feature, keeping the app maintainable and extendable.
• Helping to shape new mobile work as it expands across more of the business, including consumer monetisation and lettings.

• You have commercial experience building and shipping production apps with React Native and TypeScript, on both iOS and Android.
• You work AI-natively as a default, using tools like Claude Code fluently - and you understand what the AI produces well enough to explain and own it. If your current employer doesn’t allow AI tools, we’d expect you’ve been exploring them in your own time.
• You have strong product and design sense: you’re user-focused and care about how something feels to use, not just whether it works.
• You take quality seriously - your work is tested, solid and thought through before it ships.
• You’ve looked after a live app and see its stability, monitoring and releases as part of your job.
• You’re comfortable working independently with loose guidelines, and you’re a confident communicator who’ll share ideas and challenge in discussions.
• Experience using analytics to measure features and inform what comes next is a bonus., We care deeply about helping the tech industry become a more inclusive and diverse place and we work hard to lead by example. We are committed to Equal Employment Opportunity through attracting and retaining a complementary team of employees and building an inclusive environment for all. Candidates must be eligible to live and work in the UK and be able to perform the work specified.

How we work in 2026

Engineering at Street Group has changed. Most of us don’t write code by hand day-to-day anymore - agents do; we direct. For our mobile team, that shifts where the value is: when AI handles more of the code, what matters most is how the app looks, how it feels, what it does for the user and the ideas you bring to it. Understanding the product and the people using it sits at the heart of the role: we expect engineers to know why they’re building something, not just how.
