About the Role

This is a founding engineering role at a seed-stage AI infrastructure company building a production-grade LLM gateway — the backbone layer that helps AI-first teams integrate, route, secure, and optimise across hundreds of large language models. You'll work directly with the founding team to shape both the product and the engineering culture from the ground up.

What You'll Do

  • Design and build core backend services within a pragmatic microservices architecture, primarily in Go.
  • Develop and maintain the LLM gateway, including intelligent routing, failover, load balancing, and observability features.
  • Architect scalable systems using Kubernetes, distributed caches, and multiple SQL databases.
  • Collaborate closely with founders to define technical direction and make high-impact product decisions.
  • Evolve and redefine the tech stack as the product and team grow.

What We're Looking For

  • 5+ years of backend development experience, with strong hands-on Go (Golang) expertise.
  • Deep understanding of concurrency and experience applying concurrent programming patterns in practice.
  • Proven experience designing and working with microservices architectures and API gateways.
  • Familiarity with a variety of caching strategies and database types, and the judgement to choose between them.
  • Ability to balance architectural rigour with pragmatism — knowing when to build for scale vs. speed.
  • A self-starter mindset: comfortable picking up new technologies independently and thriving in a fast-moving environment.
  • Right to work in the United Kingdom without visa sponsorship.

Compensation & Benefits

Competitive total compensation package with significant equity. Visa sponsorship is not available for this role.

Location

On-site in London, United Kingdom.

How to prepare for a job interview at Clera

Brush Up on Your Coding Skills

For a full-time software engineering role, it's crucial that we stay sharp with our coding abilities. Expect technical questions that might involve solving problems on the spot or discussing algorithms. Practise on platforms like LeetCode or HackerRank to get comfortable with the types of questions that often come up.

Know Your Tools and Frameworks

Make sure we’re well-acquainted with the tools and technologies listed in the job description. Familiarise ourselves with any specific frameworks or programming languages mentioned. If Clera uses React or Node.js, for instance, be ready to discuss how we’ve used them in previous projects or coursework.

Make sure we can talk through our thought process for each project, especially the challenges we faced and how we solved them—this shows our problem-solving skills in action.

Prepare for Behavioural Questions

While technical skills are key, full-time positions also require cultural fit. Be ready to discuss our previous experiences and how we handle teamwork, conflict, and deadlines. Brush up on the STAR method—Situation, Task, Action, Result—to clearly articulate our past experiences when discussing how we've contributed to a team.
