About Otrium

It’s our mission to extend the life-cycle of fashion.

We enable brands to turn their unsold inventory challenge into one of their biggest opportunities. We increase the value of previous collections by finding
the right match within our shopping community, dynamic pricing and managing fulfillment services. Through our managed marketplace, brands can
open an online direct-to-consumer outlet store with full control over pricing, merchandising and visibility.

Job Description

The best thing our engineers love about Otrium is the opportunity to impact the shopping experience of millions of fashion lovers. Developers are involved within the lifetime of the product, not only on the technical side.

Stability is a significant factor, but we do not hesitate to experiment and are never shy of building groundbreaking features to change the overall customer experience. We have a future-proof tech stack consisting of the latest technologies and always curious to explore newer ones!

About Otrium

Founded and headquartered in Amsterdam, we’re a purpose-led business – we believe all clothing should be worn.

Right now, lots of fashion stays unsold. For the resources that went in and for the people who miss out, it’s such a shame. We’re here to fix this. We are an online fashion outlet marketplace and we tech-enable designer brands to find an owner for every item they produce.

We give brands an online outlet channel and digital tools to smartly connect dynamically-priced end-of-season collections with fashion-lovers. Then we give them the data so they can reproduce most-wanted items.

Our app re-imagines outlet shopping helping customers easily find reduced-price gems. We give end-of-season fashion a new start, which is smarter for the wardrobe, smarter for the wallet and smarter for the industry.

About this role

You will work with talented people from all around the world and use agile development principles. We love to help each other, and our power comes from the team game. We are a hardcore Agile team, always iterating and striving for a better, faster and scalable product.

The fastest-growing company in The Netherlands deserves the strongest tech team, and that's exactly what we strive to be. Here you will be developing features and services that will directly impact our customers’ experience and speed up the company’s growth. We expect nothing but the best from every developer. 


  • Keep the bar high on sustainable engineering by following standard methodologies, producing the best in a class of code, documentation, testing, and monitoring.

  • Work with an energetic and fun group of mobile, backend, frontend, QA engineers, as well as product owners, designers.

  • Monitor crash rates and take a proactive approach to fix problems.

  • Code review your colleagues’ work carefully and make sure the quality of the code base is going higher with every commit.

  • A collaborative approach, being open to help team members.

  • Experience shipping and operating apps at scale to a large number of users, across several geographies and locales.

About you

You are passionate for mobile development and you have strong understanding of the iOS ecosystem and its design patterns. You love solving problems and you have strong analytical skills. Although you will be in a team of 4 other mobile developers, we would love your ability to work autonomously on projects and take full responsibility for them. As a developer you are passionate about writing clean architecture and easily-testable code.

  • 5+ years of experience in native iOS development, with strong knowledge of Swift (we don't use Objective C)

  • Strong knowledge of Foundation and UIKit frameworks (we don't use Swift UI yet)

  • Deep understanding of SOLID, MVP, Coordinator, DI patterns.

  • Experience with server API implementation using GraphQL.

  • Experience with UnitTesting and automation using CI/CD.

  • Experience with the implementation of the interface from code.
  • Experience with DeepLinking
  • Experience with Git version control and Git-Flow methodology.

Nice to haves:

  • Having experimented with SwiftUI is a plus.
  • Of course we would love to see your affinity with all things mobile development. If you have worked with the Android SDK this is a big plus.

What it’s like to work at Otrium

  • You will be part of an enthusiastic and highly ambitious team with a growth and entrepreneurial mindset;

  • The possibility to learn, grow, and contribute to one of the fastest-growing startups in Europe, and soon the US (with your help!);
  • Freedom and responsibility: we believe in ownership, so we will give you full responsibility to make sure you can get the job done;
  • You’ll be working with very talented colleagues - in a different time zone - that know what they are doing as everyone has experience at other amazing fast-growing companies;
  • Next to working together, we celebrate our success together. With every target we make and record we break, we celebrate!
