DevOps Engineer
Application Deadline: 29 October 2026
Department: Software Engineering
Employment Type: Permanent - Full Time
Location: London
Reporting To: DevOps Lead
Description
We’re looking for a mid-level DevOps Engineer to join our engineering team and help us build, automate, and scale the AWS infrastructure that underpins our products. You’ll work closely with development, platform, and security teams to improve deployment velocity, system reliability, and operational visibility.
This is a hands‑on role for someone who is comfortable owning infrastructure as code, maintaining CI/CD pipelines, and championing automation and observability across the software delivery lifecycle. We place a high value on clear, well‑maintained documentation, and you’ll be expected to document your work to a standard that helps the whole team. You’ll have enough autonomy to make meaningful technical decisions, with the support of a senior team to grow into.
Key Responsibilities
- Build, maintain, and improve CI/CD pipelines (GitHub Actions) to enable fast, safe, and repeatable deployments.
- Manage and evolve AWS infrastructure using Infrastructure as Code (Terraform & Terragrunt).
- Operate and scale containerised workloads on EKS, alongside serverless workloads on Lambda.
- Design, secure, and maintain AWS networking — VPCs, subnets, security groups, routing, and load balancing.
- Manage relational databases on RDS and Aurora, including performance, backups, and resilience.
- Handle secrets and sensitive configuration securely using AWS Secrets Manager.
- Implement and maintain monitoring, logging, and alerting to ensure system health and rapid incident response (e.g. Prometheus, Grafana, CloudWatch, ELK, Datadog).
- Collaborate with development teams to improve deployment practices, environment consistency, and developer experience.
- Contribute to security and compliance efforts — secrets management, patching, access control, and secure‑by‑default configurations.
- Take part in our support and on‑call arrangements and help shape them as they mature.
- Automate manual and repetitive operational tasks through scripting and tooling.
- Produce and maintain clear, accurate documentation — architecture diagrams, runbooks, onboarding guides, and operational procedures — and champion a culture where knowledge is written down and shared rather than siloed.
