Job Details

Languages: English B2, Polish A2
Experience: 5+ years
Required Skills: AWSPostgreSQLKubernetesRuby on RailsCI/CDLinuxTerraformScripting

5+ years in DevOps, platform or infrastructure engineering, with meaningful time on AWS
Production Kubernetes, ideally EKS, well beyond having deployed to a cluster
Strong Terraform and an infrastructure as code instinct
You have run a real database migration or provider cutover, and can explain how you verified it
Comfortable with Linux, containers and GitOps
Solid scripting in Python, Go, Bash or similar, and enough application literacy to debug across the stack
English at a working professional level
Ruby on Rails familiarity preferred
Cost optimisation or FinOps experience at scale preferred
A regulated industry background preferred (ISO 27001, SOC 2, HIPAA or GDPR)

Run and evolve our multi-region AWS and EKS platform, managed as code in Terraform and deployed through ArgoCD
Own CI/CD across our repositories, on CircleCI and GitHub Actions, and keep the path from commit to production fast and boring
Lead infrastructure migrations end to end: containerising applications, moving databases between providers and regions, and cutting over with verification and a rollback plan
Manage PostgreSQL and RDS at production scale, covering version upgrades, instance sizing and performance work
Keep our Ruby on Rails runtime current, including framework upgrades, performance tuning and autoscaling behaviour
Own cloud cost: rightsizing, autoscaling, savings plan utilisation and a monthly cost report to Finance
Run disaster recovery testing and incident readiness drills, and fix what they expose
Act as the infrastructure point of contact for engineering, security and commercial colleagues
