Platform / DevOps Engineer
Aldgate, London, Hybrid (2 Days in office - Tue & Thur)
£45,000 - £75,000 + equity
Full-time
About the Team
We are a lean, high-impact core infrastructure team responsible for the platform that powers 5 distinct product teams. We believe in high automation, GitOps, and providing a seamless developer experience. Because we are a small team supporting a growing engineering organisation, the work you do here will have immediate, visible impact across the company.
The Role
We are looking for an ambitious Mid-Level DevOps / Platform Engineer to help us scale, secure, and optimise our cloud infrastructure. You won’t just be maintaining systems; you will be actively evolving our tech stack, improving deployment pipelines, and acting as a force multiplier for our product developers. If you love solving complex infrastructure challenges and want to accelerate your career by working with a modern, cloud-native stack, this is the place for you.
Please note: You must be currently located in UK AND be able to work without visa sponsorship. We are not sponsoring a work visa for this role.
What we're looking for
- Experience: 3+ years of experience in a DevOps, SRE, or Platform Engineering role.
- Cloud Foundation: Strong practical knowledge of AWS (IAM, EKS, EC2, VPCs, S3, etc.).
- Containerization: Solid understanding of Docker and hands-on experience running and troubleshooting workloads in Kubernetes.
- Automation First: Proven experience with Terraform and writing CI/CD pipelines from scratch (we use GitHub Actions).
- Drive & Ambition: You take ownership of your work, are eager to learn the tools you don’t already know, and proactively look for architectural bottlenecks before they break.
- Communication: Excellent collaboration skills. You can explain complex infrastructure concepts to product developers and write clear internal documentation.
Key Responsibilities
- Infrastructure as Code (IaC): Provision and manage AWS infrastructure using Terraform, with Atlantis driving our pull-request-based automation.
- Kubernetes & Compute: Manage and scale our container orchestration platform using Kubernetes, optimising compute resources and auto-scaling with Karpenter, and managing traffic routing via Istio.
- CI/CD & GitOps: Build, maintain, and optimize robust build pipelines using GitHub Actions and Bazel, while managing continuous delivery into Kubernetes using ArgoCD and Kustomize.
- Observability & Monitoring: Maintain comprehensive visibility into our systems and participate in incident response. You will manage and improve our monitoring stack utilizing FluentBit (logging), Mimir (metrics), Tempo (tracing), and Grafana (dashboards), alongside AWS CloudWatch.
- Security & Networking: Manage edge configurations, DNS, and security via Cloudflare, and maintain secure team access via our internal VPN.
- Developer Enablement: Act as a strategic partner to our 5 product teams. You will help troubleshoot deployment issues, optimise their build times, and build self-service tooling that makes their lives easier.
Bonus Points (Nice to Have)
We don’t expect you to know our entire stack on day one. If you have experience with any of the following, it’s a huge plus!
- Experience with GitOps principles and tools like ArgoCD and Kustomize.
- Familiarity with advanced Kubernetes tooling like Istio (Service Mesh) and Karpenter (Node Autoscaling).
- Experience with the Grafana observability ecosystem (Mimir, Tempo, FluentBit).
- Experience with Bazel for fast, reproducible builds.
- Familiarity with Atlantis for Terraform PR automation.
- Knowledge of Google Cloud Platform, particularly BigQuery and Vertex AI.
