Senior QA Automation Engineer – System Integrations Team (f/m/d)

At Enpal, we are pursuing the dream of building the largest renewable community in Europe. How do we make that happen? Enpal finally simplifies providing solar energy: We rent out solar systems, electricity storage, and wall boxes at an all-inclusive rate, supplemented by a favorable green electricity tariff; all intelligently connected to form an integrated overall solution. True to the motto "digital, decentralized, and 100% renewable", our heart beats both for the rapid development of a company and for combating the greatest challenge of our generation - climate change. 

As a Senior QA Automation Engineer IoT you will work on complex problems in delivering renewable energy solutions: from building up pipelines for automated regression testing, to educating and coaching team members around structured test design and test coverage, all the way to troubleshooting and prioritizing problem areas and bug reports.  

We offer speed, agility, and steep career growth. Our vision to make sustainable solar energy available to everyone can only come to live through our customer and product-oriented view, and the cooperation between software development, product management and lean, experiment-driven business development.  

Join us to develop your professional skills, take part in the energy revolution, and let us take ownership of the sustainable change we want to see in the world together! We are looking forward to your application.  

At Enpal, you would be  

• building software. We are serious about delivering incremental value in each iteration, and we celebrate when we improve people's experience with our solution, make an impact towards our climate goals.  

• making the team’s life easier. Nobody wants to stay up until midnight to deploy new solutions, or run the same regression tests manually day in, day out. We're about improving stability, automating as much as we can including load tests and vulnerability scans.  

• growing & learning. Whether you're experienced with MQTT, Azure, and test automation or just diving into embedded systems and IoT protocols, we’re here to grow together. You'll learn from experts across hardware, cloud, and QA—while sharing your own skills along the way.

• working on architecture & vision. We blend legacy and modern technologies—from cloud-native microservices to IoT systems. Each new requirement is a chance to evaluate what needs to evolve, and to design thoughtful, scalable solutions that address challenges across the organization.  

• steering for empathy and understanding. The best solutions start with listening—whether it's operators in the field, engineers on the floor, or stakeholders across the business. By asking the right questions and truly understanding how connected devices are used, we build systems that solve real problems, not just technical ones.

We are looking for roughly a 50% fit with for what we ask. The other 50% is a surprise to us, it is the magic you bring to the table and the diversity in which you make us grow.
