Junior Software Engineer at Catawiki — RealJobs — RealJobs

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

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 will be instrumental in Demand, Supply, and Fulfilment - our three core verticals - where you’ll help drive the future of our platform, 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?

What You’ll Do

Build: Design, develop, test, deploy, maintain and improve. You’ll be part of a team that is end-to-end responsible for its 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, 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:

A completed Master's Degree and at least 1 year of experience in your first full-time job.
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 organisation, 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.
