Senior DevOps Engineer
Job description
3 reasons you should join our team as Senior DevOps Engineer
Pioneer our infrastructure evolution - from setting up data warehouses to templating Kubernetes applications
Own mission-critical systems processing billions in transactions (no pressure, we’ve got your back)
Join a tight-knit team that values learning from mistakes over pointing fingers and allows you to come as you are.
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.
Take our platform to the next level
When millions of users trust platforms like Marktplaats and Nature.house 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 GitLab with scalable 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:
Optimize the lifecycle of our software - from code to release.
Design, build and implement cloud solutions that perfectly fit within our AWS environment.
Focus on setting up new workflows, monitoring and testing performance and introducing tools and new technologies. Think of docker, microservices and containerization.
