Senior QA Automation Engineer

DEHN is a German company with over a century of history 😮. They were born creating protections for lightning and electrical surges, and over the years they have evolved towards hardware and software related to this same field. Their devices and software are responsible for preventing electrical surges and hazards ⚡.

It is an international company, with more than 2000 employees all over the world, and they have more than 20 offices in different countries, including Spain, where their subsidiary is DEHN Ibérica.

If you want to know the history of a company with more than a century of history, they have a very cool timeline on their website.

If you notice, one of their latest milestones on this timeline is the appointment of their CTO, Christian Höhler in 2020. Which shows the dimension that technology has in this stage of the company, where software is essential.

In addition, in 2021 the DEHN digital solutions GmbH came to life and their role is to support the digital transformation of DEHN. Their mission statement is “We enable DEHN to shape its leadership in the digital future”. They do this by showing & encouraging global collaboration without boundaries in an agile way. While f_ostering a data driven culture, a customer oriented mindset and automated processes_ and building great customer software, digital services and smart solutions.​

They have hundreds of internal and external applications. From their own patented software that helps them measure thousands of environmental data, to electrical control software that saves lives, to their management applications. A company with such a history also has a very broad technological history.

The Spanish delegation has grown a lot in recent years, and it is also a strategic point for their logistics. That is why they have thought about establishing a technological operations center, a HUB, in Madrid. They have started with some operations personnel, but their intention is to create a team of 30-40 people in the coming years.

They are having problems stabilizing the infrastructure due to the accelerated growth of recent years, in addition to wanting to create new software that replaces old applications and helps them automate many actions.

The main challenge is to join and contribute to a cross-functional team working on a critical IoT system that combines cloud software with real-world hardware specifically, lightning strike sensors that help prevent damage and save lives. As a QA Engineer, your mission will be to ensure the quality and reliability of this complex and life-impacting system.

You’ll be embedded in an agile SCRUM team alongside a Product Owner, Developers, DevOps, a Scrum Master and a Solution Architect. Together, you'll support DEHN's digital transition and contribute to a broader 7-year technology strategy aimed at unifying, refactoring, and modernizing their vast software landscape—built over decades across multiple platforms, languages, and use cases.

But DEHN’s goal is to internalize these efforts by building a solid in-house team in Spain. You’ll be among the first QA Engineers to shape this new phase, collaborating closely with other roles such as Frontend, Fullstack, and Cloud Engineers.

In this role, you'll take ownership of defining and implementing manual and automated tests, especially in environments where real-world IoT devices interact with cloud-based systems. You’ll help stabilize the infrastructure, reduce downtime, and automate where it makes sense all while making sure software meets high quality standards.

This is a rare opportunity to join a growing tech team inside a century-old company with real purpose. You won’t just write test cases you’ll help define how the team builds, tests, and delivers reliable software across borders and disciplines. Are you ready to be part of something that matters?
