Senior Full Stack Engineer | AI / Fin Tech | £150k + Equity
Most personal finance products are very good at telling you where your money went.
What if one could tell you what to do next?
I'm working with an early-stage AI Fin Tech that has recently closed its pre-seed round and is building an AI-powered financial co-pilot.
They're now looking for one of their first senior engineering hires.
This isn't a role where you'll inherit a mature platform, a backlog and six layers of approval.
You'll be Engineer #1/#2, working directly with the founders to turn an early product into something people genuinely trust with their financial decisions.
You'll be responsible for things like
- Building across the full stack, including React Native on the frontend
- Making early architectural and technology decisions
- Working with financial data, account aggregation and open banking integrations
- Building the AI layer that turns financial information into useful actions
- Helping shape the product, rather than simply being handed tickets
- Setting technical standards that future engineering hires will build on They're deliberately keeping the technical requirements broad.
What matters more is that you're a very strong full-stack engineer who has built products in demanding environments and is comfortable operating with ambiguity.
Experience within a recognised technology company, high-growth startup or Fin Tech would be particularly interesting.
Exposure to AI/LLMs, financial data or open banking would be a bonus.
You'll need the appetite for early-stage life too.
There's no legacy codebase holding you back, but equally, there's nowhere to hide when something needs figuring out. £150k + meaningful equity
- Remote, but London-based
- Pre-seed, recently funded
Engineer #1/#2 If you're a senior engineer who likes the idea of getting in early enough to genuinely influence what gets built and how it gets built, drop me a message.
Equally, if someone immediately came to mind while reading this, I'd appreciate an introduction.

✨Brush Up on Your Coding Skills
For a full-time software engineering role, it's crucial that we stay sharp with our coding abilities. Expect technical questions that might involve solving problems on the spot or discussing algorithms. Practise on platforms like LeetCode or HackerRank to get comfortable with the types of questions that often come up.
✨Know Your Tools and Frameworks
Make sure we’re well-acquainted with the tools and technologies listed in the job description. Familiarise ourselves with any specific frameworks or programming languages mentioned. If IO Associates uses React or Node.js, for instance, be ready to discuss how we’ve used them in previous projects or coursework.

Make sure we can talk through our thought process for each project, especially the challenges we faced and how we solved them—this shows our problem-solving skills in action.
✨Prepare for Behavioural Questions
While technical skills are key, full-time positions also require cultural fit. Be ready to discuss our previous experiences and how we handle teamwork, conflict, and deadlines. Brush up on the STAR method—Situation, Task, Action, Result—to clearly articulate our past experiences when discussing how we've contributed to a team.
