Job description

Full-Stack Engineer | AI Startup | London - £60k-£75k

Location : London (onsite / hybrid)

We’re partnering with a VC-backed AI startup that is transforming the way organizations gain visibility into complex data systems. By combining LLMs, machine learning, and cloud-native architecture, they are building a platform that makes data ecosystems transparent, intelligent, and compliant by design.

They’re expanding their engineering team and are looking for one of their first hires — someone ready to shape the platform from the ground up.

What You’ll Do

• Build APIs and backend services in C# / .NET 8+
• Develop frontend experiences using Next.js and TypeScript
• Work in a modern Azure environment (Functions, Container Apps, Event Grid, Service Bus)
• Influence architecture, performance, and developer experience decisions
• Collaborate in a DevOps-driven culture, shipping iteratively and continuously
• Experiment with AI to solve problems creatively

Who You Are

• 3+ years as a full-stack or backend engineer
• Strong in C# / .NET and Next.js / TypeScript
• Experienced with serverless or containerized applications (Azure experience is a plus)
• Comfortable working with autonomy, ownership, and a fast-moving product
• Collaborative, communicative, and confident sharing your work
• Pragmatic with AI — you know when to use it and when to rely on your own judgment

Why Join

• Work on a mission-driven AI platform at an early-stage, VC-backed startup
• Significant impact and ownership from day one
• Fast-paced, hands-on environment where your work is seen and valued
• Collaborate with founders who care deeply about product quality and delivery
• Shape both product and engineering culture
