About the role and team

A DevOps engineer? A SRE? What’s next? The industry is going through a rise of a new discipline and its adoption, so does Catawiki. Join our Platform Horizontal as a Platform Engineer!

Recently, our Platform Horizontal underwent a major transformation from solely "managing the cloud" to becoming the largest horizontal function within the company. Today we are proudly supporting various business objectives, including Reliability, Developer Experience, Security, and Quality. The team takes a holistic approach, creating systems and tools that developers can use to deliver applications seamlessly and reliably without getting bogged down in infrastructure complexity.

Joining Catawiki as a Platform Engineer means working at the intersection of development, infrastructure, and operations. Challenges are guaranteed! So, would you be interested in this opportunity to help us set and execute this long term vision?

What You’ll Do

Your work as a Platform Engineer will shape how Catawiki teams deliver value to customers, fostering speed, reliability, and security in everything they build.

• Build a Self-Service Developer Platform: Design and maintain self-service platforms that abstract complexity, empowering teams with the tools they need to seamlessly deploy, monitor, and optimize their applications.
• Orchestrate Cloud-Native Infrastructure: Manage our Kubernetes clusters and other cloud resources, ensuring performance, scalability, and cost efficiency with FinOps.
• ​​Boost Developer Productivity: Build and enhance CI/CD pipelines, GitOps workflows, and reusable templates to accelerate development and deployment cycles.
• Drive Reliability and Scalability: Implement best practices for fault tolerance, disaster recovery, and scaling, ensuring that applications run smoothly and efficiently under all conditions.
• Monitor and Improve Platform Operations: Use and enhance observability stack to ensure platform health and resolve incidents proactively.
• Collaborate and Innovate: Collaborate with product teams to understand their needs and build solutions that empower them, while evangelising cloud-native best practices within Catawiki.

Who You Are

You prioritize developer happiness, smooth workflows, and self-service platforms. You believe that empowering developers with great tools and environments leads to better products. You enjoy sharing knowledge and collaborating with others. Next to this you are:

• Platform Builder: You design solutions that enhance developer productivity and reduce friction, applying best practices like DDD, 12-Factor App principles, and modern API design. Skilled in building internal platforms, developer tooling, and paved paths on cloud platforms (e.g., GCP, AWS).
• Automation Advocate: Skilled in automating workflows, CI/CD pipelines, and infrastructure as code (e.g., Terraform, Ansible).
• Observability Believer: You ensure developers have actionable insights into their applications through seamless integration of observability tooling (e.g., OpenTelemetry, Grafana, Datadog) into the platform.
• Ownership is your middle name: You have a strong sense of ownership for platform performance, proactively addressing issues and striving for long-term scalability and resilience.
• Collaborative Thinker: A team player who works effectively with developers and cross-functional teams to align goals and deliver impactful yet simple solutions.
• Adaptable Learner: Passionate about staying current with DevEx best practices, emerging tools, and industry trends — and eager to experiment, iterate, and improve.

Our Offices and Way of Working

Our vibrant offices in Amsterdam, Paris and Lisbon are designed to inspire and connect. Most Catawikians are within commuting distance of one of our offices and enjoy the flexibility of a hybrid work model. This means we typically ask you to be in the office 2 out of 5 days, roughly 40% of your working time, to collaborate and connect with your colleagues. Of course, if the job description specifies that the role is 100% remote—such as for certain expert or sales positions—then that arrangement will apply.
