We're hiring for a European AI cloud infrastructure company building next-generation, on-demand GPU compute - vertically integrated, running on 100% renewable energy, and growing fast. They've recently closed a funding round north of $150M and are sitting on a revenue run rate approaching nine figures, having grown roughly tenfold over the past couple of years. They're live across dozens of markets globally, hold certified partner status with a leading GPU manufacturer, and maintain strong compliance credentials (SOC 2 and similar) - because when you're handling access to high-value compute at scale, identity and access management isn't an afterthought, it's core infrastructure.

We're looking for three Senior Backend Developers to help shape how the IAM platform evolves across a diverse product portfolio (GPU instances, clusters, serverless compute, storage), rather than treating identity as a bolt-on to a single product line.

What you'll work on:

  • OAuth 2.0/2.1, OIDC, SAML 2.0, JWT, RBAC and ReBAC, MFA, TOTP, passkeys and FIDO2 - with real scope to work on workload and machine identity/service accounts.
  • Contribute to large-scale resource planning systems and internal tooling spanning multiple services, building APIs for fast, robust resource provisioning alongside our SRE and data centre teams.

What we're looking for:

  • 5 years+ as a backend Golang engineer, with strong hands-on IAM knowledge.
  • Proficiency with Go: web APIs, concurrency, performance optimisation, caching.
  • Experience with TypeScript (we also use Node and React).
  • Experience designing, building, and maintaining microservice architectures.
  • Experience maintaining public RESTful APIs.
  • A TDD mindset.
  • Kubernetes/DevOps familiarity is a plus.

Practicalities:

  • Hybrid, a few days a week from the London office.
  • Full-time, permanent.

How to prepare for a job interview at Realm

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 Realm uses React or Node.js, for instance, be ready to discuss how we’ve used them in previous projects or coursework.

Showcase Your Projects

Bring along a portfolio that highlights our best work. This could be code samples, GitHub repositories, or any side projects we’ve built. 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.
