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.

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.

What are we looking for?

Must-have skills:

  • 5+ years DevOps/platform (senior), production ownership

  • Experience of planning and implementing DevOps practices end-to-end 

  • Deep AWS (VPC, ECS, IAM, RDS/ElastiCache or equivalents, networking)

  • Terraform at scale (modules, remote state)

  • CI/CD with GitHub Actions, including automated deploys to production

  • Containers (Docker); comfortable operating services on ECS or K8s

  • Strong Linux networking (DNS, TLS, load balancing, firewalls, VPN)

  • Comfortable owning a multi-quarter infra initiative: TCO, design, vendors, cutover, rollback

  • Fluent English (both spoken and written)

Strongly preferred:

  • Replacing managed AWS services with self-hosted (Postgres HA, Redis/Valkey, Kafka, OpenSearch)

  • Email infrastructure (MTA, SMTP, IP reputation, DKIM/SPF/DMARC) — Halon or similar

  • Cloudflare (DNS/WAF/Access)

  • Observability beyond CloudWatch (Prometheus/Grafana/Loki or equivalent)

  • Prior work with multi-region SaaS or EU data residency

  • Cost-driven architecture / FinOps mindset

Would be a plus:

  • GCP (BigQuery/certificates)

  • Comfortable reading Ruby or Go (used in our services and tooling)

  • AWS Certificates 

  • Experience planning or/and executing migration to on-prem, colo, or private cloud (both partial or hybrid), including colo/bare-metal ops: IPAM (NetBox), Ansible, image-based provisioning (Packer or equivalent), HAProxy/Nginx

  • Comfortable automating operational tasks with shell and/or Python

Responsibilities

  • Operate and evolve AWS multi-account / multi-region infrastructure

  • FinOps

  • Implementing IaaC using Terraform modules

  • Ensure safe infrastructure changes across network, storage, and services, with zero-downtime deployments.

  • ECS services, blue/green deploys, Docker image pipelines

  • Reliability: CloudWatch/PagerDuty/Sentry, capacity, cost tags

  • Security baseline: IAM, secrets (SSM), Cloudflare edge rules

  • Partner with engineers on release automation and production readiness
