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 a talented team working on an early-stage product with high potential. The team is rebuilding infrastructure in a legacy industry, emphasizing collaboration without silos or red tape.

Location: London

Working Policy: Onsite full-time, due to the early stage and the value of in-person collaboration

Salary: Up to £100,000 (depending on experience) + equity

Interview Process: 3 stages, fast and focused

You will work across frontend and backend as a Full Stack Software Engineer in a small, fast-paced team, using C#, .NET, React, and Azure. The role offers autonomy and end-to-end ownership.

This role involves active participation in product decisions, strategy, and user interactions, not just coding tickets.

• Mid–Senior Full Stack Software Engineers: typically 3+ years of experience
• Strong skills in C#, .NET, and React
• Passionate about creating products users love; FinTech or B2B SaaS experience is a plus but not essential
• Enthusiastic about early-stage startup environment
• Driven to build impactful solutions

You will collaborate closely with founders, influencing product and business strategy. If you're seeking ownership, fast learning, and to build with C#, .NET, React, and Azure, apply now.
