Job Description

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 we offer over 75,000 unique items in auction , carefully curated by our passionate in-house experts.

Having sold over 20 million unique objects to date, we’re on a mission to become the world’s most popular destination for special objects. As a growing, diverse and sustainable scale-up, we proudly live by our core values: 

• Taking ownership and driving impact 
• Being open to change and feedback
• Being passionate about our mission and our customers. 

If these values resonate with you, we’d love to explore how you can join us on this exciting journey! 

About the team

As we are expanding internationally at a high pace, you will be at the centre of our business development – this is a very exciting time to join the Logistics team! Your team is responsible for offering cheaper and better ways of shipping sold items from sellers to buyers – and we are starting to offer new shipping methods in many more countries.

Our Logistics team, like all our Engineering teams, is interdisciplinary: you will cooperate directly with Backend, Frontend, iOS, and Android Engineers, and together you are responsible for all shipping and logistics functionality of our Catawiki apps and our web app. You will create software that helps both our buyers and our sellers to optimise their delivery workflow. Apart from the Engineers, your other team members include the QA, UX Designer, Product Manager, and your Tech Lead Manager, who leads and guides the Engineers on a daily basis.

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 Engineering team members, you will build beautiful and adaptable web frontends on top of scalable microservices. Most of these serve our sellers and buyers, and some are geared towards our own customer services and internal operations teams.

You ensure that your web components work well and are responsive to desktop, tablet, and mobile screens. By measuring and monitoring system performance, you optimise the performance of your products.
In addition, you will use A/B experiments, agreed upon with your Product Manager and User Experience Designer, and backed by data analysis, to add product features and deliver the best user experience on the platform. 

What you’ll bring

You are a Front-end Engineer with extensive frontend experience in multiple technologies, with an impressive portfolio of past frontend deliveries, and eager to expand your knowledge and impact, ready to take the next step in your career. As a Senior Developer, you are effective in lifting the level of your team, and you love to cooperate with Front-end Engineers of other teams.

• 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 are passionate about what you do and eager to follow industry trends.
• 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.
• You have an Experimental Mindset: we value a test-and-learn approach – validate ideas quickly, iterate based on insights, and don’t be afraid to discard what doesn’t work. Once validated, we build for the long term with scalability and maintainability in mind.

We look for Engineers who are motivated to learn new things, ship new features, and pursue new and interesting challenges. Our front-end stack is mainly built using TypeScript and ReactJS .

Additionally :

• A minimum of 7 years of experience as a Front-End Engineer using JavaScript/TypeScript as your main stack.
• Proven experience working in product companies and 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.
• You are proficient in web technologies – JavaScript/TypeScript, HTML, CSS.
• You are familiar with popular libraries like ReactJS, NextJS, Redux, CSS Modules, Tailwind, and/or Rails.
• You understand the browser environment and how it interprets code – Critical Render Path, CORS, Caching, CDNs.
• You have an understanding of good programming principles – SOLID, DRY – and have a good problem-solving approach and mindset.
• When building features, you consider A11y, security, SEO, performance, testing, observability, i18n, and Typing (if applicable).
• You know how to monitor and manage an application in production: you build it, you run it, you love it!

Bonus Skills :

• While this is a frontend position, familiarity with  NodeJS and experience running it in production is a great plus. This knowledge will help in collaborating effectively across the stack and optimising frontend-backend interactions.

In return

• A competitive Annual Gross Base Salary depending on your level, competencies, and overall experience.
• Health Insurance from day 1 (including dental coverage), with access to multiple hospitals and clinics and a vast wellness network.
• A Work From Home Allowance to help with your monthly household bills.
• Commuting between your home and our office is covered by Catawiki.
• Amazing Office right in the centre of Lisbon.

Why You’ll Love Working with Us

• Create a Visible Impact by working at scale in a global organisation that serves millions of customers across 80+ categories. In our flat structure, every role has a broad scope that directly impacts both our customers and the business.
• Learn and Grow with Us through our Learning & Development initiatives, which include clear development plans and mentorship programmes designed to support your career progression.
• A Culture of Connection defines us. We’re a passionate, diverse and collaborative team of 800+ Catawikains and 60+ nationalities, all coming together to build a one-of-a-kind marketplace. 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 our team. 
• Celebrate Life’s Moments with us at Catawiki. When you join us, you’ll receive a €100 Catavoucher, and on each birthday, you’ll get a €50 Catavoucher to celebrate. Enjoy an extra day off each year to “Pursue Your Passion”. We also recognise significant work anniversaries (3, 5, 8, 10 years) with additional time off, plus extra leave for life’s big moments like marriage, engagements, or moving house.
