We’re on a journey and it has only just begun

SeaPattern’s growth took off in the spring of 2025. One year later, we are a team of just over 20 people from diverse backgrounds and nationalities, but with one thing in common: we are building technology that truly makes a difference.

We work close to reality, close to the systems, and close to each other. What we develop is tested in real-world environments and directly contributes to increasing renewable energy production in existing hydropower plants, without new infrastructure or environmental impact.

What is it like to work at SeaPattern?

Our employees have full ownership of their respective areas. By combining ownership with close collaboration across disciplines, we've created a highly supportive environment for both personal and professional growth. This way of working has enabled us to move rapidly from research and development to real-world deployments and the next phase of industrialization.

Where are we heading?

Interest in our technology is growing rapidly, both in Sweden and internationally. The opportunity ahead is global, and we're building the team that will help make it happen.

We are now looking for a Test Engineer who wants to help shape the next generation of renewable energy technology.

About the role

As a Test Engineer at SeaPattern, you will be responsible for testing and verifying the mechanical and electrical systems in our turbines. Your work will cover the full testing process, from component-level testing to end-of-line (EoL) and system-level functional testing in our workshop.

You will also plan test campaigns together with the engineering team and carry out field tests at hydropower plants. The role is hands-on and involves developing test methods and equipment, troubleshooting mechanical and electrical systems, documenting results, and using test data to drive improvements.

You will work closely with our electrical and mechanical design engineers throughout the testing and verification process.

Your work will include:

• Testing and verifying mechanical and electrical systems in our turbines, from component-level testing to end-of-line (EoL) and system-level functional testing in our workshop.

• Planning test campaigns together with the engineering team and carrying out field tests at hydropower plants.

• Developing test protocols, test plans, and test rigs.

• Troubleshooting mechanical and electrical systems when issues arise during testing, both in the workshop and in the field.

• Documenting test results throughout the testing process and driving improvements based on data.

• Working closely with electrical and mechanical design engineers.

We believe you're an engineer who combines a structured approach with a practical, hands-on mindset. You enjoy understanding how complex systems behave in the real world, troubleshooting technical problems, and turning test results into concrete improvements.

You are comfortable taking significant ownership of your work and enjoy being part of a small, fast-moving organization in an intensive phase of development.

To succeed in this role, you likely have:

• An M.Sc. in Mechanical Engineering, Electrical Engineering, or a related field.

• Experience in testing and verification of mechanical or electromechanical systems.

• Experience working hands-on with technical systems while maintaining a structured approach to testing and documentation.

• The ability to troubleshoot mechanical and electrical systems and identify root causes of technical issues.

• A structured and analytical approach to documenting and evaluating test results.

Experience within renewable energy, marine technology, or manufacturing is considered an advantage.

You enjoy working closely with colleagues, communicate clearly in English, and are motivated by developing next-generation renewable energy technology.
