Job description

Senior Software engineer / Y-combinator backed startup - Stockholm

I'm working in partnership with one of Stockholm's most exciting startups, building the agentic application layer for a trillion-dollar industry!

A small, high-pace team who have previously been building within some of Stockholm's coolest companies, they are now building an industry-transforming product to optimise workflows, automate processes and minimise poor, costly decisions within critical industry.

With strong investment, fantastic traction on the product & momentum, already being used across 4 continents, they are looking to add 1 more senior engineer to their engineering team - an opportunity for someone to join at an incredibly exciting and pivotal point in their journey, from early stage!

What we are looking for:

• Senior engineer with a track record of tackling a diverse set of complex technical challenges and problem spaces, building products for real-world impact
• Product minded, outcome oriented. You like to see and own the bigger picture, you have experience building and driving features & scalable systems end-to-end, with an understanding and concern for the impact on the user
• Startup coded: We are a small, high pace & high trust team, with a lot of exciting technical challenges and complexity. We are looking for engineers who aren't afraid of startup pace and ambiguity, have a real 'get shit done' mentality, but also are able to collaborate seamlessly with the rest of the team.
• 5+ Years (ideally) as a software engineer, with strong experience in building reliable, scalable systems at backend & platform layers.
• Our application & workflow engine in built in Typescript, so experience with that is great to have.
• You've been using AI to assist your development and coding for the last 1-2 years, and it would be great if you have experience building AI agents, AI-powered systems into production, and have some knowledge about AI harnesses & Evals

This is a role where you will be trusted with a tonne of ownership, an opportunity to have a huge impact within a cutting-edge company building for the real world. Joining a super flat, ambitious and humble team, where you can be part of that long-term mission!

This is a permanent role, based out of our Stockholm HQ.

Currently unable to assist with Visa sponsorships or relocations. You must have full right to work in Sweden without the need of assistance at this stage
