iOS Engineer at Catawiki

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. 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 Catawiki! Our Engineering teams are interdisciplinary: you will cooperate directly with Backend, Frontend, iOS, and Android Engineers, and together you and your team are responsible for all functionality of our Catawiki apps and our web app within the team’s product domain. You will create software that helps our buyers and our sellers by delivering new features and reducing user friction. Apart from the Engineers, your other team members include a 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 native mobile app features on top of scalable microservices. These serve both our sellers and our buyers. You'll ensure that your features work well on all recent iOS and iPadOS devices, and recent OS versions. You keep track of system performance, and optimise it where needed. 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 an iOS Engineer with extensive experience with Swift and Cocoa Touch frameworks (UIKit and SwiftUI), with an impressive portfolio of past mobile deliveries, and eager to expand your knowledge and impact, ready to take the next step in your career. You are effective in lifting the level of your team, and you love to cooperate with iOS 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" too: 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 iOS stack is fully Swift-based, our screens are both UIKit and SwiftUI, and we use the VIPER architecture. Additionally: • A minimum of 5 years of experience as an iOS Engineer using Swift 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 and implementing features with a focus on stability, performance, and consistency. • You are proficient in native technologies - SwiftUI, UIKit, and the Swift standard library. • You routinely apply object-oriented and functional, imperative and declarative programming paradigms where needed. • You have experience with testing frameworks - XCTest, XCUITest, Quick & Nimble, snapshot testing, and/or Swift Testing. • You have an understanding of good programming principles - SOLID, DRY - and have a good problem-solving approach and mindset. • You can discuss and propose API designs with engineers with a focus on user-friendliness and long-term benefits. • When building features, you consider performance, testing, security, localisation, accessibility, and observability. • 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 an iOS position, familiarity or affinity with other tech stacks (frontend web, backend, Android), 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. Where you'll be This role is based in Lisbon, Portugal. We also offer an excellent relocation package for this role. In return • A competitive Annual Gross Base Salary depending on your level, competencies, and overall experience. • Meal Allowance Card stipend per working day, in addition to salary. • 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.
