DevOps Engineer

Octopus Money is hiring a DevOps Engineer to own and evolve the AWS platform that our customer-facing products run on. The platform is defined entirely as code: a single Terraform monorepo, orchestrated with Terramate, spanning dev, staging and production accounts across multiple tenants. You will join a small platform team and take shared ownership of everything from networking and IAM to container services, databases, observability and the CI/CD pipelines that ship it all. 

This is a hands-on engineering role. You will spend most of your time writing Terraform modules, reviewing infrastructure PRs, running plans through GitHub Actions, and working with product engineers to get new services onto the platform safely. Octopus Money is FCA-regulated, so security, least privilege and auditable change are part of the day job, not an afterthought. 

A large share of the recent work has been driven by our ISO 27001 programme and external penetration testing. You will own the technical side of both: implementing controls as code, producing the evidence auditors ask for, and closing pentest findings through the normal PR process. 

What you'll do:

• Design, build and maintain reusable Terraform modules forAWS services (ECS, ALB, RDS, DynamoDB, Lambda, Cognito, CloudFront, SES, SQS, SNS, KMS, WAF, Route 53) and wire them into per-tena
