We are looking for a Senior DevOps Engineer to join our team!
You will own and evolve Mailtrap's production infrastructure — a multi-region AWS platform powering high-volume email sending and testing. You will keep it reliable, secure, and cost-efficient day-to-day.
You will also lead a key strategic initiative: planning and executing a partial migration of selected workloads from AWS to rented bare-metal / colocation infrastructure to cut costs — a hybrid-by-design effort, not a full cloud exit. You will decide what moves and what stays, design the target platform (likely Kubernetes or a similar orchestrator on bare metal), and own the migration end-to-end, from business case to cutover.
Our engineering team thrives in an agile, continuously improving, and automation-oriented environment. We value ongoing evolution, objective evaluation of our processes, and taking action to make things better.
