We’re always looking for the brightest and best to join us here at the Software Improvement Group. We offer fantastic benefits, competitive salaries and a working environment that can’t be matched.

All Vacancies
  • The work with SIG was very beneficial for our due diligence and helped us in the decision making process. The combination of deep technological understanding and the necessary pragmatism when looking at early stage companies proved very value adding for us and also for our target company.
    Christian Knott Partner at Capnamic Ventures
  • SIG’s work is crucially important for Waternet as we elevate our online services. This digital era demands new ways of thinking about software in terms of technology, vendors and operational issues, and SIG guides us in all three areas.
    Mario Kortman Director Digital Transformation at Waternet
  • The SIG toolset has enabled us to gain valuable insight into the code quality of potential acquisition targets, thereby enabling the company to make decisions based on quantitive measures rather than subjective opinion.
    Arun Mundray CTO at Kallidus
  • The pragmatic nature of the Better Code Hub tool, combined with its goal to guarantee growth-proof quality for the future, seems to make it a great fit with the mindset and ambitions of Exact.
    Erik Ammerlaan Software Engineer at Exact
  • For our major risks in large scale development with or without partners we turn to SIG to set the benchmark for quality delivery and improvements of the code base. Their professionalism in these matters certifies the long term sustainability of our software assets and as such our investments.
    Carl Tilkin-Franssens CIO at Acerta
  • SIG delivered a high-quality report analysis in which you really see that this is their core expertise. Based on facts and their extended knowledge of software quality they provided clear advice for further improvement.
    Hidde Andriessen CIO Office at KPN
  • With the help of SIG we brought the software quality to the next level which helps us to deliver our installations faster.
    Yvo Zethof R&D Project Manager at VanRiet
  • SIG triggered a behavioural change. The assessment did not just measure the quality of the software, but the score itself also served as a motivating catalyst among developers. Now developers actively pursue high quality software and continually improve upon their skills.
    Nico van Didden Project Manager at ProRail
  • In assessing a vendor for a critical software purchase, TÜViT told us that SIG was the only one organization certified to determine if (1) the purchase was a good foundation for future excellence (2) it was worth the investment (3) it could integrate it seamlessly into our own organisation. We wouldn’t hesitate to work with SIG again.
    Markus Hölzlein General Manager Digital Products at Weltbild GmbH
