Catawiki is a curated online marketplace for special objects, hosting 75,000 auctions per week with over 10 million monthly visitors. The company has sold over 25 million unique items and operates across three core verticals: Demand, Supply, and Fulfilment.
As a Backend Engineer, you'll join a small, autonomous, and highly collaborative Agile team supporting one of these verticals. You'll be responsible for designing, developing, testing, deploying, and maintaining scalable microservices that power the platform's search and discovery, bidding, curation, logistics, payments, and support systems.
Key responsibilities include:
- Building end-to-end microservices with ownership of quality, resilience, and maintainability throughout their lifecycle
- Collaborating across product, design, frontend, backend, and mobile teams to deliver product innovations
- Identifying opportunities to improve engineering processes and advocating for development best practices
- Fixing bugs and refactoring code to maintain product reliability
- Participating in Technical Week, a dedicated innovation and knowledge-sharing initiative
You'll bring 7+ years of software development experience with strong object-oriented programming foundations, plus 3+ years working on customer-facing products in e-commerce, fintech, or SaaS. You have expertise designing and deploying high-availability, low-latency backend services, solid understanding of API design, SQL, and relational databases. The tech stack is primarily Ruby, though prior Ruby experience isn't required if you're eager to learn. Excellent English communication, collaborative mindset, and solution-oriented thinking are essential.
