Platform Engineer in London

This role exists to increase the operating leverage of Gattaca’s engineering team. You’ll own the production platform, developer experience, observability, deployment workflows, internal tooling, and the feedback loops that let engineers ship quickly. At Gattaca, infrastructure directly affects market share and P&L. Strong production and platform engineers can have an outsized impact here because the platform is still early: there is room to set direction, establish the right operating model, choose the right abstractions and automations, and turn currently scattered workflows into reliable systems the whole team builds on.

Your day-to-day work will span these main areas:

• Production systems and reliability: You’ll own the infrastructure and operational workflows that keep Gattaca’s production systems predictable. That means making deployments safe and repeatable, keeping rollback paths clear, improving host and service health, and making sure incidents are easy to understand when they happen.
• Observability and alerting: You’ll help build the feedback loops engineers rely on to understand production. System metrics, logs, dashboards, traces, and alerts should make the state of the system obvious, especially when something is wrong. False alerting stops that, helping to really understand the system to know what to alert and what not to.
• Developer experience: Given the rate of work and the size of the team, a lot of operational work can become manual unless someone owns it properly. You’ll improve the path from local development to production: faster CI, more reliable builds, better test environments, cleaner deployment tooling, simpler configuration and secrets workflows, and internal tools that remove repetitive manual work. Small improvements here compound across the whole engineering team and make a big difference.
• Infrastructure performance: Our systems are latency-sensitive, and infrastructure details matter. You’ll work close to the boundary between application code and the machines it runs on: host-level tuning, networking behaviour, kernel settings, CPU isolation, resource contention, noisy neighbours, and the practical details of running high-performance services in production.
• AI and internal tooling: We want to use AI where it genuinely increases engineering leverage. As the team moves quickly, useful context can become fragmented across scripts, docs, dashboards, incident notes, one-off fixes, and individual engineers’ workflows. You’ll help turn that into shared tooling that runs safely.
• Security: You'll help maintain the security and integrity of our systems, from production infrastructure to developer workstations. This includes access controls, secrets management, endpoint and infrastructure hardening, vulnerability management, and security monitoring, with a focus on making secure practices part of everyday engineering workflows.

Requirements

• High agency. A lot of the work will start as something vague. You should be comfortable finding these problems yourself, deciding what matters, and taking them from observation through to a real fix.
• High drive. There is a lot to improve, and platform engineers can be huge levers on team output. We want someone who moves quickly, raises the standard around them, and keeps pushing important work forward without needing a queue of tickets.
• Strong infrastructure fundamentals. You have experience deploying, managing, and automating cloud infrastructure.
• Experience with infrastructure automation and CI/CD. You should be comfortable building processes with simple tooling or automation.
• Good judgement around observability and operations. Alerts should be specific, actionable, and reserved for things that matter. Monitoring should reflect how the system actually behaves today, not how it behaved six months ago. If an alert becomes noisy, you should notice and fix it before the rest of the team notices it.

Skills we value, but aren’t a requirement:

• Blockchain fundamentals, Ethereum infrastructure, the transaction supply chain, or Maximal Extractable Value (MEV).
• Experience managing infrastructure on AWS/Latitude/OVH.
• Experience with Terraform and Ansible.
• Experience with high-performance or latency-sensitive Linux production systems.
• Experience building internal tools used by other engineers.

Compensation:

• Top-of-market base salary.
• Bonus tied to company and individual performance.
• Equity on joining, with more earned through performance.
• Private healthcare.
