Tech stack
JavaScript. :) We use it through React and React native for all our clients and through Node on Heroku hosted servers, AWS lambda functions and Intel NUCs for our photo robots. We complement this core with interesting technologies such as GraphQL, React Hook Form, styled-components, Expo and much more. There are always new exciting technologies around the corner for us to explore.

Meet Helena, Engineering Manager
I started part-time at Sellpy in 2019 as a Software Engineer. This was during my last year of studying at KTH and from the first day I felt that Sellpy was a perfect fit for me. Fast-forward one year and I was starting full time in the Internal team after having done my Master’s thesis at Sellpy as well. Now - after 2.5 years in total at Sellpy - I’ve started working as Engineering manager for the Internal team.
Can you tell us about interesting projects you have been a part of?
During my Master’s thesis I investigated the use of machine learning models for segmenting the images in our ads, a super interesting project that afterwards was put into production.
Another interesting feature was when I took part in improving our algorithm for picking orders in the warehouse, a fun but challenging project - especially since the problem is NP hard!
Lastly, a project that I’m currently working on is collecting and structuring data for our registered items so that we can re-use the data later on when we receive a similar item - an exciting feature that will help us process more items and create better ads.
Why Sellpy?
It’s very rewarding to work at a company that’s working towards transforming the very industry it’s part of. It brings unique challenges that no one really has solved before which at times can feel almost intimidating, but that feeling is quickly changed to excitement when all your colleagues are kind, fun and ambitious people that makes it a complete delight to solve these problems together.
I would recommend Sellpy to developers who want to make a big impact by finding simple solutions to challenging problems. Sellpy is growing fast, a developer’s opinion is valued highly and you will be a part of driving the company forward. I’d say that Sellpy is built on team players - we feel safe in knowing that we will always help each other out if needed, but you shouldn’t be afraid to trust your own skills as well!
3 teams of Engineering
Selling Services
Our sellers and their items is what makes Sellpy possible. Our unique and vast inventory is all thanks to them and we need to provide them with a great experience.
The Selling services team is responsible for the journey of our sellers. From their first bag order, through their items being described and photographed and all the way to the items being sold.
Buying Services
Access everything, consume nothing.
This is the vision of Sellpy. In order to reach that vision buying second hand items need to be as easy as buying new. The team is constantly working towards not just the best second hand experience, but the best e-commerce experience period. This is no small task and it involves great user interfaces, availability across devices and countries and accurate search and discovery.
We have come far on this journey but there is so much more to do!
Internal
Describing 250 000 items a week, Capturing more than 1 million images a week and sending 200 000 items a week. These are some of the great challenges of working with our internal systems. On top of that every item is unique!
Having doubled our processing ability in only a year we are in a very expansive phase and that results in very exciting challenges. We transfer items between warehouses, across borders, in order to provide the best experience for our customers. We automate photography with photo robots that ensure high quality and fast processing speeds. We make descriptions of items more accurate, provide tools for quality control and much more. Our internal systems are already international but the growth has only started!
