Backend Software Engineer

Portugal

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 110,000 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.

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 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?

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, a week dedicated to promoting creativity (after 2 product sprints), innovation, and knowledge sharing across domains.

What you’ll bring

As Software Engineer, you already understand the full life cycle of web development and see opportunities in front of you. You're curious, solution-oriented and have a strong customer focus. Our stack is mainly focused around Ruby, however, if you’re passionate about learning new things then prior experience with Ruby is not essential. Next to this:

At least, 4+ years of experience with customer-facing products in related industries, e.g. e-commerce, fintechs, SaaS
At least 4+ years with software development, in specific OOP (object-oriented programming)
Experience designing, implementing, and deploying backend services, with a focus on high availability, low latency, and consistency.
Good understanding of APIs design
Familiarity with SQL and relational databases
Excellent communication in English
Comfortable raising concerns, sharing new ideas, documenting, and finding opportunities for solution alternatives.

As a passionate engineer, you bring these values to Catawiki:

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 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.
