We have just under 100 employees globally, 60 in Amsterdam, rising to 75 before the end of the year. After recent series B $15mn funding injection, it’s fair to say that everyone here is excited about the future of Harver.


Just imagine.. after a short walk from Central Station, Rik (our legendary Office Manager) will show you our magical views of the IJ from the 7th floor. There's space for you to sit in the sun (on swings) and there are delicious, free and healthy lunches!. You'll soon meet the sky diver, the DJs, the Game of Thrones enthusiast, the judo guy, the painter and board game fanatic. Your first task; figure out who’s who.


Well, you will be brining technical leadership to Harver, creating a shared direction through frontend architecture whilst guiding the engineering team to a common goal. Sound like something you like to do?

Together with your teammates and, Phil our Engineering Head who loves tech such as: GraphQl, MobX and React, you will be impacting our business and disrupting the industry by:


  • Leading the holistic design of Harver's software systems; co-owning the overall architecture within the lead engineering team of 3. 
  • Enabling the whole team to deliver the business roadmap
  • Supporting and delegating design and architecture of subsystems to senior engineers
  • Mentoring senior and medior engineers whilst always promoting good software engineering principles
  • Re-building frameworks for easier and quicker module creations
  • Understanding our legacy platform and recommending big but feasible changes
  • Continually innovating on our recruitment application process
  • Owning the delivery software from development to production 



  • You’ll hold a BSc or MSc in computer science or a similar subject
  • Your understanding of good engineering practices is strong and your communication of these practices is exemplary (BDD & TDD, CI/CD, pair programming)
  • You are a JavaScript guru with in depth knowledge in React, GraphQL & Node.JS 
  • You bring experience in Frontend Architecture
  • You have the ability to self manage and take care of changing requirements
  • Your hands-on approach to products ensures you 'make it happen'
  • You like to fail, succeed, and learn together, but also like to have some fun whilst doing so
  • You will have worked on a SaaS product before, so you understand the fast turn around
  • You believe in building a culture of testing (we'd love it if you've used Jest/ Cucumber/ Mocca / Chai)


We'd love for you to bring experience within the B2B industry. It would be awesome if you brought angular experience (to help us transition away from it). AWS, Lambda and Jenkins knowledge would also be very useful.
