Senior Software Engineer (Backend)
Series A | eCommerce x Fintech | Meaningful equity
Buying clothes online still isn’t a great experience.
Sizing is inconsistent, returns are costly, and customers are often left guessing. Yet despite all the innovation in eCommerce, this problem remains largely unsolved.
We’re working with a high-growth, well-funded Series A startup that’s changing that — enabling Try Before You Buy experiences for leading fashion retailers. The product is live, gaining traction, and now entering a critical phase of growth, including expansion into the US.
To support that, they’re rebuilding and scaling key parts of their platform.
This is where you come in.
You’ll join a small, experienced engineering team and work directly with the CTO on the systems that sit at the heart of the product. This isn’t about maintaining legacy code or picking up tickets. It’s about building, improving, and scaling a platform that directly impacts customer experience and revenue.
The environment is backend-leaning, built around Node.js, TypeScript and MongoDB, with an API-first, event-driven approach. But more important than the stack is the mindset — engineers here are trusted to take ownership, think in systems, and deliver end-to-end.
You’ll be given the space to focus, the autonomy to make decisions, and the responsibility to get things into production quickly and properly.
What they’re looking for is someone who has seen scale — or at least understands what it takes to get there. Someone who has worked in a startup or high-growth environment, where ambiguity is normal and ownership isn’t optional.
You’ll likely be strongest on the backend, comfortable designing and building production systems, and thoughtful about performance, trade-offs, and long-term maintainability. You don’t need to know everything, but you do need to be curious, pragmatic, and capable of figuring things out.
If you’ve had exposure to eCommerce, payments, or marketplace platforms, that’s helpful — but not essential.
What makes this opportunity stand out is timing.
The team is still small, but not at zero. The product is live, but not finished. The business has funding, traction, and a clear direction — but plenty left to build.
There’s a genuine opportunity here to shape both the platform and your own role as the team grows over the next 12–18 months.
And importantly, you’ll be part of that journey in a meaningful way, with equity that reflects early-stage impact and upside.
The package includes a salary up to £85,000, flexible holiday, hybrid working (one day in the office per week), and a range of additional benefits — but the real value here is the chance to build something that matters, in a team where your contribution is visible from day one.
If you’re an engineer who enjoys building real products, solving meaningful problems, and working in an environment where ownership and impact matter more than process, this is worth a conversation.
