Test Automation Engineer (Machine learning)

Belgium, Vlaams Gewest, Houthalen-HelchterenSoftware development - Virtual Power Plant & Machine Learning

Job description

As a Test Automation Engineer you develop software for the purpose of testing our machine learning, planning and optimization algorithms: test automation frameworks, test result reporting and troubleshooting, simulating time-series data streams like solar production or EV charging sessions etc. Our services provide a unique challenge when it comes to test automation: we run software on an edge device, connected to a variety of local hardware (EV chargers, heat pumps, energy meters, etc) and our cloud back-end; our machine learning algorithms optimize the energy consumption patterns of the connected local hardware. Designing and implementing a reliable and efficient test strategy for such a solution will be one of the most interesting challenges of your career.


In this role, you'll create test setups that put our forecasting and optimization algorithms through their paces. You build test setups in pure software, abstracting the connected hardware devices. This involves simulating environments or fabricated time-series data streams, to feed into our machine learning algorithms with the purpose of triggering happy paths as well as edge cases. You implement test scenarios on those test setups and make sure they run nightly or as part of our CI/CD pipeline. You'll work with the software development team to make sure their code is testable, and with the DevOps team to make sure your test infrastructure fits nicely into the CI/CD pipelines. 


You ensure that the test reports of all levels (Unit, CI/CD, System, End2End) are merged and can be viewed transparently at any time. You continuously design and implement the metrics to monitor the correct operation of our solutions. You work on large-scale simulations to stress test the system and identify bottlenecks.


The test infrastructure you put in place supports the companies rapid international growth, and enable us to maintain high up times and comply with demanding SLA's. You will help us to grow our IoT solution into a robust, scalable and configurable platform that forms the basis of the Enervalis Smartpower Suite©. Connected to hundreds of thousands of edge devices around the world, collecting millions of data points and controlling assets like EV charge points, battery storage systems, heat pumps and more. This energy management platform powers our state of the art algorithms to predict the production and consumption of green energy and balance supply and demand on the electricity grid. Basically your daily work will help transform the global energy sector to shift from fossil-based systems to renewable energy sources.


This is a full-time position in our office in Houthalen-Helchteren (Belgium). We offer a hybrid model of working two days at the office, and three days from home. The focus of this role is on software quality assurance, not on product development.


You’ll join a young and dynamic company that cares about people and team spirit. This job is varied and challenging, and offers the opportunity to grow together with the organization. We offer competitive salary packages, in line with your experience and competences.

Job requirements

Your profile:

  • A bachelor’s degree in informatics, computer science, industrial science or equivalent engineering.
  • Fluent in English (speaking, reading and writing), you’re a strong communicator that can coordinate with the development team and take ownership of the test automation topics.
  • You are organized, structured and have a systematic work approach.
  • You have a hands-on attitude and a passion for quality.
  • You can work autonomously and take initiative to propose solutions.

Technical skills:

  • At least 3 years experience with test automation and test management tools, as applied to backend testing, covering all levels from unit testing to end-to-end testing. Strong plus if you have worked on test automation for machine learning algorithms.
  • You have a software development background. (Strong plus if this is in java, python and/or javascript)
  • Hands-on experience with machine learning techniques like forecasting, planning or optimization algorithms
  • Experience with modern cloud-based development and operation environments.
  • Experience with API testing.
  • Experience with at least one scripting language.
