Senior Full Stack Developer

Who we are

A piece of the moon, a complete dinosaur skeleton, the Pope's hat, the world's smallest book - at Catawiki, we come across exceptional objects such as these every day. 

Catawiki is the leading online marketplace to buy and sell special objects. We offer over 75,000 special objects in auction every week — each reviewed and selected by one of Catawiki’s hundreds of in-house experts specialised in Art, Design, Jewellery, Fashion, Classic Cars, Collectables and many more.

We've sold 10 million unique items to date and it’s our mission to become the world’s most popular auction destination for special objects.

We’re an innovative, pioneering and fast-growing scale-up. If you think you can make a difference to our team, go ahead and apply.

A little bit about the team

“Hi, I am Jorge! As a Full Stack Engineer in Catawiki, I love being part of the whole value delivery process to our end-users, acting close to them, and incorporating their feedback for continuous improvement. I enjoy building intuitive UIs, designing, developing, and implementing applications & solutions using a range of technologies and programming languages from both front-end and back-end stacks.

I cherish the company of the brilliant minds around me, which keeps me motivated to grow every day. Join us if you are also passionate about building scalable software solutions, and have a genuine interest in delivering value to end-users.“

What you'll do

Here at Catawiki, you will make an impact by improving and delivering product innovations for the Catawiki platform. Along with other members of the Development team, you will build scalable microservices while measuring and monitoring system performance. In addition, you will use experimentation, backed by data analysis, to add product features and deliver the best user experience on the platform. 

What you’ll bring

As a Senior Engineer, which resembles the Staff Engineer level, you have a proven track record on influencing and guiding the development of the Back-End tech stack in your company. You have often operated outside of the boundaries of your team, and can give many examples on your effectiveness doing so. With Catawiki you will continue to do so.
With your extensive software engineering knowledge, you like to cooperate with engineers throughout the company, regularly focusing on cross-cutting business features, or just to help out your colleagues. You also provide guidance on a platform and company wide arhcitectural level. Apart from this you have coached multiple engineers over the years, for longer periods of time, and you will apply your coaching skills in Catawiki to help your fellow engineers grow in the best possible way. 
Last but not least you have often (co-)created opportunity proposals and RFC's. You feel at home when you need to describe problems, opportunities, pros and cons of solution alternatives, and tying these to technical solution proposals, regularly comparing new techniques to proven existing techniques. You feel comfortable in explaining discussing your proposals with Product Managers, UX-designers and multiple Tech teams. As a passionate engineer, you bring these values to Catawiki:

  • You are a passionate experienced 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 comfortable in a startup environment and are ready to jump in and help if needed.
  • You keep the company's values close to your heart and enjoy being in a diverse environment.

We look for engineers who are motivated to learn new things, ship new features, and pursue new and interesting challenges. Our backend stack is mainly focused around Ruby and the frontend is mainly built using React. However, if you’re passionate about learning new things then prior experience with Ruby and React is not essential. Additionally:

  • Proven experience in collaborating closely with other engineers and product managers to become a valued member of an autonomous, cross-functional team.
  • Experience in designing, implementing, and deploying services with a focus on high availability, low latency, and consistency.
  • Proficiency in languages such as (but not all of!) Python, Ruby, Go, Java, PHP, C#, and other applicable backend languages is preferred.
  • Experience in both Functional and Object-oriented programming paradigms.
  • Expertise in frontend frameworks such as React, Angular, or Ember. 
  • Good knowledge of Relational databases and familiarity with NoSQL databases.
  • Experience and/or interest in Test Driven Development (TDD).
  • You know how to monitor and manage the application in production: you build it, you run it, you love it!
  • Knowledge of container orchestration (Docker, Kubernetes) is a big plus.

Here’s what we can offer you

This is your chance to become part of a fast but sustainable growing tech company! You'll be part of an enthusiastic, highly motivated team of 800+ international Catawikians; you'll have big responsibilities and can really create something. Additionally, you can expect:

  • A diverse and international team with over 50 different nationalities.
  • Catawiki provides you with a membership to the O’Reilly learning platform.
  • Work from home office set-up to make sure you have all you need in an ergonomically-friendly manner.
  • A bike scheme for employees that helps realise a tax advantage which makes a bike up to 35% cheaper than buying!
  • Our entrepreneurial environment encourages everyone to take initiative and experiment with new ideas. You’ll actively contribute to the growth of the Catawiki platform.
  • For people living outside of NL we offer a great relocation package for you and your family
  • The fun part! Our Activity Committee plans everything from ‘CataFooty’ to International Food Festivals, Friday Drinks, Board Game Nights, Pub Quizzes and Boot Camps!
  • And there’s more! Paid holidays, Holiday Allowance and a fantastic pension plan paid for by Catawiki.

Our commitment to you 

Catawiki’s eclectic team represents an international and intergenerational mix of people from different professional and cultural backgrounds. We foster an inclusive and queer-friendly work environment, committed to making every Catawikian feel welcomed and empowered. Whatever your story, we encourage you to bring your unique perspective to the table.

Catawiki stands with Ukraine and encourages people displaced by the current conflict to apply. In addition to the several initiatives we’ve launched, we’re open to ideas on ways we can continue to support the humanitarian effort.

Our offices and new way of working

We’ve embraced an activity-based way of working, meaning our team can choose how they split their work week between home and the office, in line with our remote framework and guidelines. In locations where we have physical offices, most employees enjoy two days at the office to connect and collaborate with each other.

Our experts and sales staff in local markets work 100% remotely – in most cases from home. Some key positions are hired remotely, while we also offer relocation services for colleagues needing to be closer to the office.
