…empowering thousands of Mendix makers across the globe

…taking pride in what you build, again and again

…working with an experienced product team to solve customer problems



Your Opportunity

We face many exciting challenges across our product portfolio as we scale up. As our company and teams grow, so does our product offering, increasing the number of technical challenges and opportunities to empower Mendix teams in unique and innovative ways.  

We are looking for software engineers to join us on our journey. You will be joining the CLEVR Developer Tooling unit within CLEVR. As a software engineer in our product team, you solve real customer problems through an innovative and efficient application of your technical knowledge. You will be part of our multidisciplinary product team and work closely with our product designer and product manager. You are in charge of the ‘how.’  



Why is our team and your role important? 

Mendix is booming. Every year thousands of makers join the community to create excellent applications that solve problems. Low- code offers tremendous speed in application development and makes software quality more manageable in the overall software development lifecycle. But that doesn’t mean you are off the hook for quality. Broken access control is replaced by misconfigured access control. Copy-paste mistakes in lines of code are replaced with copy-paste mistakes with activities and microflows. There is always a need to address software quality; low-code is slightly different. During our years of Mendix development, we created tools that helped the developers at CLEVR improve the overall software quality of their applications.  

  • Even for technical experts, it is pretty tricky to pinpoint the precise location of an issue in a microflow. Sometimes Mendix feels like a black box. In 2012, we decided to productize our knowledge and created a tool that provides deep-level insight into the logging and performance of your Mendix application. We called it the Mendix Application Performance Diagnostics tool (APD). APD is part of the Mendix platform from Mendix 7 onwards. 

  • Even with Mendix, regression testing is essential. During the development of various large applications, we noticed that existing functionality could break quite easily. The existing test automation solutions are complex in both usage and skill level. In 2014, we decided to productize our knowledge and created a tool that made test automation for Mendix applications sturdy and accessible by many. We called it the Mendix Application Test Suite (ATS). ATS is part of the Mendix platform from Mendix 7 onwards. 

  • We believe Mendix shows many similarities with a young software language, and developers experience similar struggles. Mendix knowledge isn’t widely accessible, and there is little development guidance. In 2019, we decided to productize our Mendix expertise and created a tool that brought the power of automated code review to the Mendix platform. We called it the Application Code Reviewer (ACR). A unique code review solution for Mendix contains over 175+ Mendix best practices. 

We continue to build products that improve the overall developer experience for Mendix teams, helping organizations & developers to reduce their time-to-market, increase developer productivity, improve their risk & reputation management, reduce the application lifecycle total cost of ownership, and deliver an excellent end-user experience on all their Mendix apps. 

I have been working at CLEVR for a few years, and one of the things that makes me smile every day is seeing how our team and our products keep on growing. Steve Jobs once said, ‘There's just a tremendous amount of craftsmanship between a great idea and a great product.’ That craftsmanship is what we do. Every day we are driven to deliver quality solutions to Mendix teams around the globe, giving them an incredible experience that makes their work life easier. There’s nothing that can make me prouder than that.” – Derryn Zwart, Lead CLEVR Developer Products
