🎯 The Role

This is an operations-led position. You will be working day to day on AWS, our infrastructure-as-code, our CI/CD setup, observability, and the on-call rotation.

A meaningful part of the work is automation: when we find ourselves doing the same thing twice, we usually invest in tooling rather than writing another runbook. Most of that tooling is written in Go.

To give a sense of the environment: infrastructure is defined with Terraform and Terramate, with Atlantis running plan and apply on pull requests. Workloads run on EKS with Karpenter, Cilium and Istio, deployed through ArgoCD. Observability is built on Grafana, Loki, Tempo, and Prometheus compatible metrics.

✅ Key Responsibilities

• Operate AWS infrastructure, Kubernetes platform, and internal tooling for engineering.
• Manage infrastructure-as-code, CI/CD setup, and observability systems.
• Handle on-call rotation and production incidents.
• Develop automation tooling, primarily in Go.
• Collaborate across engineering, product, and security teams.

📌 Required Qualifications

• Several years of hands-on experience operating production systems on AWS and Kubernetes, including genuine on-call ownership.
• Solid working knowledge of AWS fundamentals, including VPC, IAM, EKS, and RDS.
• Practical experience with Terraform and a GitOps-style delivery workflow (ArgoCD, Atlantis, Flux, or similar).
• Comfort writing code, with some prior experience in Go or a willingness to pick it up.
• Strong written and spoken English, and the communication skills to drive design discussions across engineering, product and security.
• Flexible on location as long as working hours overlap with European time zones.

🎁 Benefits

• Open-minded teams, a welcoming and inclusive company culture, plus the opportunity to make a real difference with a game-changing health tech product.
• A competitive salary package based on your unique expertise, skillset, and impact on the product plus stock options.
• In-office, remote and hybrid work opportunities.
• The equipment whatever you need to be happy and productive.
• A premium SIMPLE subscription.
• 21 days annual leave, plus bank holidays
• Flexible hours. We focus on your results, not how long you spend at your desk.

🛂 Visa & Eligibility

We're flexible on some locations as long as your working hours overlap with European time zones.
