About the Job
On our path to becoming the most visited online curated marketplace for special objects, our Engineering team is on a mission to deliver the best experience across our platforms by building best-in-class products for search & discovery, bidding, curation, logistics, payments, and support.
We're a scale-up with customer-facing challenges dealing with high-scale (75k auctions per week) and high traffic (more than 10 million visitors per month). As a Junior Software Engineer, you’ll support one of our 3 verticals - Demand, Supply, or Fulfilment - improving and delivering product innovations for our platform.
Working in small, fully autonomous, and highly collaborative Agile teams, you will build scalable, maintainable, and resilient microservices and features. That's why we are looking for bold, curious and open developers! Are you ready to join?
Where you'll be
Our office is located in Amsterdam. We don't sponsor relocation or visas for this role in detail - Please only apply if you have the right to work in the Netherlands.
What you will do
- Build: Design, develop, test, deploy, maintain and improve. You’ll be part of a team that is end-to-end responsible for their own microservices.
- Collaborate: Work closely with product designers, product owners, front, back, and mobile engineers to share new ideas and make our processes even more efficient.
- Growth: Support our great engineering culture, by documenting and advocating for best development practices - constantly improving the quality of our products by fixing bugs and refactoring the code base where necessary.
- Learn: Boost your career by testing new technologies and participating in our Technical Week (after 2 product sprints): a week dedicated to promoting creativity, innovation, and knowledge sharing across domains.
What you’ll bring
We look for engineers motivated to learn new things, ship new features, and pursue new and interesting challenges. Our backend stack focuses on Ruby (not too different from Python), and the frontend is mainly built using TypeScript and React. However, if you’re passionate about learning new things, prior experience with Ruby is unnecessary.
As a Junior Engineer, you have a lot of growth and opportunities ahead of you. At Catawiki, we will give you much room to explore your interests and strengths and provide you with the support you need to grow rapidly and become a true back-end professional.
A strong candidate has:
- At least 1 year of experience in your first full-time job
- A completed Master's degree
- Some experience collaborating with others in a professional or academic setting, whether with other engineers and product managers in a software development environment, or similar interactions in another organization, making you a valued member of an autonomous, cross-functional team.
- You have experience with at least one mainstream programming language (including, without limitation, Ruby, Python, Go, C++, C#, Java, Scala, Kotlin, etc.) and the willingness to learn other programming languages as necessary (we use Ruby).
- You have some fundamental knowledge of SQL and relational databases.
- Nice to have: You are familiar with Application Programming Interfaces, whether the API is a web technology such as HTTP, REST, JSON, etc., or another API technology such as gRPC.
Additionally:
- You are a passionate engineer with a strong eye for detail.
- You strive to be a great team player and don’t shy away from new challenges.
- You are someone who takes initiative and is ready to jump in and help if needed.
- You keep the company's values close to your heart.
- You enjoy working in a diverse and dynamic environment..
- You possess a "growth mindset" in which you take the initiative to further your personal skill set as a software developer, whether by learning new skills and/or technologies or by seeking new opportunities

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.
