At Catawiki, every day brings the extraordinary! Whether it’s Daniel Ricciardo’s Formula 1 Car, a Woolly Mammoth’s Skeleton, Lady Gaga's Jumpsuit or Usain Bolt’s running shoe, we encounter exceptional objects every day.
We’re a one-of-a-kind marketplace for buying and selling special objects. Each week, more than 100,000 unique items are auctioned, all carefully curated by our passionate in-house experts.
Having sold over 25 million unique objects, our mission is to become the world’s most popular destination for special objects. As a growing, diverse and sustainable scale-up, we proudly live by three core values. If these values resonate with you, we’d love to explore how you can join us.
- Taking ownership and driving impact
- Being open to change and feedback
- Being passionate about our mission and our customers.
Your Mission
As an Engineering Manager in our Fulfilment domain, you will lead a cross-functional team focused on improving the post-order journey - especially the shipping and delivery experience for our buyers and sellers. Shipping is one of the most critical and friction-prone parts of our marketplace. Your mission is to build a strong, empowered engineering team and shape the technical foundations that make our fulfilment experience reliable, scalable and customer-centric.
You won’t be coding full-time, but you will own the technical direction, guide architectural decisions, and ensure we build systems that enable faster, safer product delivery. At the same time, you’ll grow engineers into high performers and future leaders. This is a high-impact role at the heart of our marketplace experience.
What You’ll Do
Your work as an Engineering Manager will shape how Catawiki evolves the auction journey, helping the team deliver reliable, thoughtful, and high-impact experiences for bidders and buyers, leading and growing a high-performing engineering team, creating a culture of ownership, accountability and continuous improvement.
- Drive technical direction and system ownership for the Fulfilment domain, ensuring scalable, maintainable architecture that supports long-term product ambitions.
- Improve the post-order customer experience, reducing shipping friction and increasing reliability across the buyer journey.
- Partner closely with Product and UX to shape the roadmap, translate business priorities into technical strategy, and deliver customer-centric solutions.
- Enable faster and higher-quality delivery, establish engineering standards, improve processes, and introduce measurable quality metrics.
- Navigate ambiguity in a scale-up environment, balancing immediate delivery needs with strategic platform improvements.
What You’ll Bring
You measure what matters, stay close to the details when needed, and know when to guide versus when to step in. You are comfortable balancing technical leadership with people leadership, and you care deeply about the team, the systems, and the outcomes they own. Next to this, you have:
- Strong software engineering foundation with 5–10 years of experience.
- Proven people leadership experience (1-2+ years) growing, coaching, and developing engineers, including managing performance and career progression.
- Experience working in cross-functional product teams, partnering effectively with Product, UX and business stakeholders.
- Technical decision-making confidence, guiding teams through architectural trade-offs and complex system challenges.
- Ownership mindset, able to tackle problems end-to-end and drive solutions forward in ambiguous situations.
- Marketplace, e-commerce or scale-up experience (nice to have), particularly in logistics, shipping, or post-order flows.
- Strong stakeholder management and communication skills, influencing across teams and seniority levels.

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 measure everything, implement gradual changes, and accept failure as normal. Being allergic to toil, you leverage tooling and automation. You enjoy sharing knowledge and helping others. Next to this you are:|
Cloud-Native Adept: Proficient in Kubernetes, cloud platforms (e.g. GCP, AWS, Azure), and container orchestration with a minimum of 2 years of production experience.
Automation Advocate: Skilled in automating workflows, CI/CD pipelines, and infrastructure as code (e.g., Terraform, Ansible).
Observability Believer: You are experienced in using and maintaining observability stacks (e.g. Prometheus, Grafana, ELK, OpenTelemetry) to ensure platform reliability, performance, as well as insight-driven improvements.
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: While it’s practically impossible to keep up with all developments in the cloud-native ecosystem, you strive to continuously evolve with new tools, technologies, and best practices.
