Senior DevOps Engineer (AWS Platform & Backend Support)

We are looking for a Senior DevOps Engineer to take ownership of our cloud infrastructure and help evolve a modern AWS-based platform. You will work on reliability, observability, automation, security, and CI/CD — and occasionally support backend engineers with troubleshooting or small contributions to our backend services.

What you'll do

• Own and improve AWS infrastructure across staging and production environments.
• Build, maintain, and standardize Infrastructure-as-Code using Terraform.
• Manage and optimize containerized workloads on ECS Fargate.
• Strengthen observability: metrics, dashboards, alerting, and logging.
• Improve CI/CD pipelines using GitHub Actions.
• Enhance IAM, secrets management, and overall cloud security posture.
• Perform maintenance of databases running on RDS (Postgres, MySQL).
• Support backend teams with debugging, migrations, or small changes in Node.js/NestJS when needed.

What you'll need

• 5+ years of experience as a DevOps Engineer.
• AWS Expertise including VPC, Route53, ECS Fargate, Lambda, RDS, SQS/SNS, CloudWatch, and S3.
• Strong experience with Terraform.
• Deep understanding of AWS networking and secure infrastructure design.
• Experience operating RDS (backups, upgrades, failovers, troubleshooting).
• Hands-on CloudWatch experience (metrics, dashboards, Logs Insights, alarms).
• Strong proficiency with Docker and containerized deployments.
• Experience with GitHub Actions and modern CI/CD workflows.

Nice to have

• Experience with Docker image hardening and optimization (multi-stage builds, non-root users).
• Familiarity with API gateways or automating OpenAPI specifications.
• Experience integrating SSO/SAML/OIDC for cloud and internal tools.
• Experience with distributed backend architectures (microservices, event-driven, multi-service systems).

What they offer

• Competitive salary with company shares (VSOP) to be part of the journey.
• Annual learning budget and personal development paths.
• Company pension scheme and company events.
• Flexible benefits: e-bike or e-moped, discounted BVG public transport ticket, USC membership.
• Hybrid work model — work from office, home, or anywhere.
