Job description

We work where finance, insurance and technology meet, a field of large, high-stakes problems and real technical opportunity. The industry around us still runs on manual process and fragmented data, and closing that gap is most of what our engineering team does.

We are a young and fast-growing business with our own engineering team, and technology sits at the centre of how we compete. The scope is broad, the pace is quick, and AI agents are already in live use here doing real work in real decisions. There is a great deal still to build.

We are hiring a Junior Software Engineer to take real ownership from the start. The work is hands-on and the learning curve is steep. You’ll ship code that reaches users within your first few weeks and get exposure across front end, data and internal tooling.

You’ll see the effect of your work directly. You’ll own problems that matter, watch them go live, and see the outcome, with support as you take on larger pieces.

What You're Do

• Build and maintain features across our front end using React and TypeScript
• Develop and support data pipelines in Microsoft Fabric, moving and transforming data from Dataverse, market data APIs and submissions
• Write Python and T-SQL to drive data processing, automation and analysis across Azure SQL and Fabric
• Build and maintain Power BI reports and DAX measures that turn data into decisions the business acts on
• Build and support the services and APIs behind our products and internal tools, deployed on Azure
• Contribute to our AI agent tooling, including MCP server development
• Take part in code review and pick up strong engineering practice as you go

You’ll pick most of this up here. We are looking for someone strong in part of the stack, curious about the rest, and quick to close the gap.

What You'll Bring

Required

• A solid programming foundation: you can read, write and debug code with confidence
• Working knowledge of at least part of our stack (React/TypeScript, Python, SQL), and the ability to get up to speed quickly on the rest
• Initiative: you investigate a problem properly before escalating it, and you follow through
• Clear communication and a collaborative approach
• An appetite for learning and a high standard for your own work

Nice to Have

• A track record of building your own projects. If you have been shipping personal work in your own time, ideally over two years or more, that carries real weight with us
• Experience with the Microsoft data stack: Azure, Microsoft Fabric, Power BI and DAX, Azure SQL, or .NET and C#
• Exposure to ETL or data pipeline work in any environment
• Any hands-on experience with LLM or agent tooling, professional or personal
• Curiosity about finance, insurance or fintech
• Around two years of development experience, commercial or self-directedd

What We Offer

• Broad and early exposure across front end, data and internal tooling
• Real ownership and visible impact in a growing business
• Direct mentorship from experienced engineers, and a close view of how the business actually works
• A clear path to grow as the company and your responsibilities scale
• Benefits including pension and holiday allowance, with full details provided at offer stage
• Location: on-site, City of London

Who Thrives Here

• The people who do best here are technically curious, self-directed and genuinely enjoy building things: the sort who tinker with projects for their own interest and take pride in doing them well. If you want to be pointed at hard problems, learn quickly and see your work make a difference, this will suit you.
