Join Speer IT and Work on CoconTheWeb

Are you a developer who wants more than just working through tickets? Then you might be exactly who we’re looking for at Speer IT. Here you’ll work on CoconTheWeb, a web application used daily by thousands of professionals to map out telecom infrastructure across the Netherlands—and far beyond. Not your average software. Not your average job.

What we’re looking for

We’re looking for a developer with technical insight and initiative. Someone who doesn’t shy away from responsibility and dares to make technical decisions. You’re critical, but constructive. And yes, sometimes you’re just right.

  • You’re someone who takes the lead when necessary
  • You can explain and defend your technical decisions
  • You challenge your team to get better

What you’ll do

  • Contribute to the further development of CoconTheWeb
  • Design and improve system architecture
  • Optimize code quality and performance
  • Develop new features from idea to implementation
  • Discuss and explain technical decisions to your team
  • Write code yourself—because that’s your superpower

No GIS experience? No problem—we’ll teach you what you need to know.

What we expect from you

  • At least 5 years of experience as a web developer
  • Experience with PostgreSQL and/or Oracle
  • Strong in JavaScript and C#
  • Git is second nature to you
  • You build REST APIs and microservices like it’s nothing
  • You know your way around Entity Framework and LINQ
  • You think in solutions, even with complex problems
  • You keep it simple when possible, robust when necessary
  • You know the difference between real Agile and just meetings for the sake of it

Bonus points if you:

  • Have experience with ExtJS (and still enjoy your work)
  • Know Redis or similar key-value stores
  • Don’t flinch at a Linux terminal
  • Know what GIS is (and if you had to Google it just now, that’s also fine)

This job offers more than just a challenge

Empowering personal growth
At Speer IT, you’re in control of your own career. We promote personal development with tools for growth, knowledge sharing, and learning opportunities.

Time for rest and relaxation
We know that people who work hard also need to recharge. That’s why we offer 28 vacation days per year (full-time), plus 1 extra day off for each full quarter without any sick leave (up to 32 days max). Every 4 weeks, our chair masseur visits the office. And we organize regular outings, BBQs, and team events.

Our terms of employment

  • A competitive salary that matches your experience
  • A solid pension plan
  • Travel reimbursement: €0.23 per km or OV compensation by arrangement
  • A hybrid, innovative, and informal working environment
  • Position is 40 hours/week, but 32 or 36 is negotiable
  • Office lunch is on us
