Infrastructure Engineer vacatures in Delft

Senior DevOps Engineer

• Hybrid
• • Delft , Netherlands

Job description

3 reasons you should join our team as Senior Devops Engineer

1. Design and own infrastructure, don't just maintain it. We want builders, not ticket handlers.

2. Work on mission-critical systems that process billions in marketplace transactions with real impact.

3. Collaborate with a tight-knit team that values learning from mistakes over pointing fingers and lets you be your authentic self.

At OPP, we're building the infrastructure backbone for Europe's leading marketplaces, and we need a technical pioneer who gets excited about both system architecture and teamwork to support us. Unlike traditional roles where you're maintaining someone else's infrastructure, you'll be designing and maintaining everything from scratch. Our secret? We keep all infrastructure in-house, giving you maximum impact and endless opportunities to think of new solutions.

When millions of users trust platforms like Marktplaats, Nature.house and IKEA with their payments, your infrastructure makes it possible. You'll be working with a sophisticated AWS environment that combines EC2 instances and Kubernetes clusters, backed by MySQL, OpenSearch, and Redis. Think scalable GitLab CI/CD, Terraform for infrastructure as code, and Lambda functions - all powering billions in yearly transactions.

Depending on your expertise and interests, you'll dive into:

• Designing and implementing cloud solutions from scratch

• Driving our AWS architecture forward with real ownership

• Building new workflows, monitoring, testing performance and adopting fit-for-purpose tech

• Owning critical CI/CD and release processes

• Ability to keep infrastructure stable, scalable, secure, and performant

How we invest in you

• An all-in salary up to €95.000 annually
