Full Stack Engineer | TypeScript, React, C#, .NET

Full Stack Software Engineer

SaaS | Early-Stage Start-Up | Experienced Founders | C# | .NET | TypeScript | React | Azure

I’m hiring a Full Stack Software Engineer to join one of the most ambitious, talented, and genuinely brilliant teams I’ve worked with. This is a rare opportunity to work directly with proven founders on an early-stage product with huge potential. They're rebuilding the infrastructure of a legacy industry from the ground up – no silos, no red tape.

📍 Location: London

🕐 Working Policy: Onsite full-time – it's early stage, and the team gets massive value from in-person collaboration

💰 Salary: Up to £100,000 (depending on experience) + meaningful equity – it's a brilliant time to join

🛠 Tech: C#, .NET, TypeScript, React, Azure

🧭 Interview Process: 3 stages. We keep things fast, focused, and respectful of your time.

You'll be a Full Stack Software Engineer in a small, fast-paced team, working across frontend and backend to ship real features using C#, .NET, React, and Azure. You must be confident across the stack – this role offers real autonomy and end-to-end ownership.

This isn’t just an engineering role. You’ll be actively involved in commercial decisions, product strategy, and user conversations – not just handed tickets.

We’re looking for:

• Mid–Senior Full Stack Software Engineers — while we don’t fixate on years, 3+ years' experience is typically what we'd expect. We need engineers to hit the ground running.
• Strong across C#, .NET, and React
• Passionate about building great products users actually love. Experience in FinTech or B2B SaaS would be highly advantageous but by no means an essential.
• Excited by early-stage, in-office startup life
• Hungry to build something with lasting impact

You’ll work closely with founders, shaping both product and business from the inside. If you're a Full Stack Software Engineer who wants real ownership, fast learning, and to build with C#, .NET, React, and Azure – apply now.
