Software Engineer - Golang

London - Hybrid

Join a high-growth AI company building cutting-edge platforms used by engineering and research teams worldwide.

We’re looking for a Senior Full Stack Engineer who’s strongest on the backend (Golang preferred) with solid TypeScript/React ability. You’ll work across the stack, shape architecture decisions and help take a technically complex product from proven prototype into scalable, production-grade reality.

This is a great fit for someone who enjoys ownership, solving hard technical problems, and working closely with product and research teams.

The Role

• Lead backend development with a focus on building clean, well-structured APIs
• Work across the stack with TypeScript and React when needed
• Contribute to architectural decisions, focusing on scalability, reliability and clean design
• Work on containerised services and contribute to platform-level improvements
• Collaborate with a cross-functional team to deliver new features end-to-end
• Help maintain high engineering standards through testing, documentation and code quality
• Play a key role in maturing the platform as the company grows

What We’re Looking For

• Strong experience in backend development (Golang ideal, other backend languages considered)
• Solid frontend experience with TypeScript & React
• Experience building production-grade REST APIs
• Good understanding of concurrency, clean architecture, and system design
• Familiarity with containerisation and cloud environments
• Comfortable working across backend, platform, and some frontend areas
• Able to explain architecture decisions and trade-offs clearly
• Pragmatic, hands-on engineer who enjoys working in smaller teams

Nice to Have

• Experience with Python or ML-adjacent environments
• Exposure to Kubernetes or infrastructure-as-code tooling (eg. Terraform)
• Messaging systems and distributed workloads
• Experience contributing to a cloud-agnostic or multi-cloud environment

Why Join

• Work on technically challenging problems at the intersection of engineering and AI
• High ownership, high impact role in a growing team
• Supportive environment with strong learning and development focus
• Competitive compensation and stock options
• Flexible hybrid working model

How to Apply

If you're a backend-leaning engineer who can operate across the full stack and wants to join an ambitious, mission-driven team, we'd love to hear from you.
