Your Role

As a Student Mechanical Engineer (Summer Worker or Thesis Worker), you will:

· Work alongside experienced mechanical and RF engineers on real antenna product development projects, including counter-UAS (C-UAS) applications.

· Assist in the mechanical design of antenna structures, enclosures, radomes, and mounting hardware using 3D CAD.

· Support structural, thermal, and environmental analysis (such as FEA, vibration, and ingress protection) of rugged products for field use, including counter-UAS systems.

· Help build, assemble, and test prototypes, and work with suppliers on machined, sheet-metal, composite, and 3D-printed parts.

· Prepare manufacturing drawings, bills of materials, and documentation, and share your findings with the team. Thesis workers will also complete their master’s thesis on a topic linked to our product development.

Who We’re Looking For

· Students about to start or pursuing a master’s in Mechanical Engineering (or a related field such as Mechatronics or Product Development), looking for summer work or a master’s thesis position.

· Some coursework or project experience in mechanical design, materials, or manufacturing processes.

· Familiarity with 3D CAD and simulation tools (such as SolidWorks, Creo, ANSYS, or COMSOL) is an advantage.

· Enthusiasm for learning, problem-solving, and teamwork.

· Good verbal and written English skills (Finnish is a plus, but not required).

What’s in It for You

· Mentorship from experienced mechanical and RF engineers.

· Hands-on experience with real-world engineering challenges, from concept to prototype.

· Flexible working arrangements to suit your study schedule.

· A supportive, innovative, and international team environment.

· The chance to contribute to meaningful projects, complete your master’s thesis on a real industry topic, and grow your professional network.
