Job Description

As a Technical Tester you are responsible for ensuring the quality of our .Net Core and Python-based applications. In this role you will use your experience with a variety of testing techniques and tools, as well as a strong understanding of the software development process.

Your main tasks will be:

  • Reviewing software requirements and proactively identify functional, technical and integration related defects
  • Designing, determining and executing functional tests for our applications
  • Automating functional tests using scripts and CI/CD pipelines
  • Analyzing test results on database impacts, errors, bugs and usability
  • Advising and collaborating with our development teams to ensure that all defects are identified and resolved in a timely manner in order to ensure quality throughout the software development life-cycle


Helin consists of people with backgrounds in aerospace engineering, energy industry, renewables and the academic world. This makes us curious to understand exactly how things work and how they can be improved. We love to propose better alternatives in a constructive way. This requires empathy about existing bottlenecks, curiosity about domain knowledge, analytical problem solving skills and expertise in data analytics and software development.

We highly value an inquisitive mindset and eagerness to learn. To feel successful within our fast-growing scale-up environment you will need to be comfortable asking questions in order to acquire more in depth knowledge.

The following suits you:

  • Prepare integration tests and end-to-end tests
  • Integrating independently automating tests using Azure CI/CD Pipelines in Azure DevOps
  • Testing distributed cloud-based and Docker-based applications
  • Experience working within a small or medium-sized enterprise (not only big corporates)
  • Experience with software development (Python, .Net Core in combination with C#) is a plus
  • Experience with tests that include hardware (RevPi and PLC’s) is a plus.
  • It’s an advantage to have affinity with industrial standards and protocols such as OPC and Modbus used for our communication.
