Senior F#/.Net enigneer

Knowit is a leading Nordic IT consultancy firm, dedicated to helping our clients achieve their business goals through advanced technological solutions. With over 4,500 professionals across various business areas, we specialize in software development, IT consulting, and digital transformation, all aimed at creating sustainable futures. Knowit is listed on the Stockholm Stock Exchange and operates in 21 countries, providing cutting-edge solutions and exceptional client service.

For our client – a Danish manufacturer of branded toys – we’re looking for a Senior F# Engineer to join a small, product-focused team building solutions from scratch. 

This is not a legacy-maintenance role. The team (3 engineers, Product Manager, UX Designer) works in an agile setup, experiments with technology, and takes real ownership of what they build. 

We are looking for candidates living in Poland.

Tech stack:

  • AWS (S3, RDS, SES/SQS) 

  • F# backend (core focus) 

  • React frontend 

  • Elastic for observability 

  • Integration with a Salesforce SaaS solution 

Key skills: 

  • Strong senior-level F# experience 

  • Alternatively: an exceptionally strong .NET (C#) engineer who is genuinely ready to move into F# 

  • Experience designing and consuming synchronous and asynchronous APIs 

  • Team mindset – someone who supports others, shares knowledge, and can mentor junior engineers when needed 

  • Very Good knowledge of English

If you enjoy working close to the product, influencing technical direction, and building without legacy baggage — this might be a good fit. 

What We offer:

  • A B2B business contract (if you are interested in an employment contract, let us know!).

  • Flexible working hours and the option to work remotely.

  • An international environment for knowledge sharing and participation in innovative projects.

  • Development of technical, soft, and language skills, including training programs and co-funding of certifications.

  • All equipment necessary for work.
