Laser-Prozessingenieur (m/w/d)

Solestial is pioneering the future of space-based solar power by developing advanced solar technologies optimized for the harsh conditions of space. Our innovative, low-cost, and scalable solar arrays are engineered for next-generation satellites, spacecraft, and orbital infrastructure. We are driven by a mission to power the space economy and unlock limitless opportunities in orbit and beyond.

The Role

As our Laser Process Engineer, you'll support the development, optimization, and scaling of laser-based manufacturing processes used to build next-generation solar cells and modules. Working closely with our Principal Laser Engineer, you'll help develop and deploy laser processing technologies while supporting day-to-day process troubleshooting and continuous improvement efforts across development and production environments.

This is a hands-on role focused on laser process development, equipment troubleshooting, and manufacturing execution. You'll work across laser dicing, polymer ablation, masking, and related manufacturing processes while partnering closely with Engineering, Manufacturing, Tooling, and Automation teams. This role is ideal for someone who enjoys working directly with hardware, solving technical challenges, and helping transition innovative technologies from development into production.

Your Mission

• Support development of laser processing techniques for solar cell and module fabrication
• Assist in design, build, and setup of laser tooling and related mechanical systems (fixtures, chucks, alignment setups, etc.)
• Run experiments, collect data, and help refine process settings.
• Develop and improve laser equipment automation scripts used for both R&D and manufacturing
• Work in CAD to support tooling and integration design efforts
• Assist with installation, debugging, and commissioning of laser and related equipment
• Partner with automation and mechanical engineers to integrate laser systems into larger tools
• Help transition processes from R&D/pilot into production environments
• Create manufacturing documentation (SOPs, work instructions, and Process FMEAs) and support operator training
• Contribute to general lab and pilot line activities, including running builds and supporting production lots as needed

What You Bring

• Bachelor's degree in Mechanical Engineering, Materials Science, Optical Engineering, Physics, Manufacturing Engineering, or a related technical field
• 1-4 years of engineering experience (internships, co-ops, research, or industry experience included) in a hands-on technical environment
• Hands-on experience with lasers, optics, photonics, or laser-based materials processing through academic research, internships, or industry experience
• Comfortable working with hardware-building, debugging, troubleshooting, and improving physical systems
• Experience collecting and analyzing data to solve technical problems and improve process performance
• Ability to write basic logic scripts to automate equipment sequences (motion control, laser controls, I/O handling, vision systems, and calibration)
• Basic 2D and 3D CAD experience (AutoCad and SolidWorks or similar)
• Familiarity with laboratory, pilot-line, or manufacturing environments
• Strong problem-solving mindset and ability to work effectively across engineering and operations teams

What Gives You an Edge

• Experience with laser dicing, ablation, cutting, marking, welding, or other laser-based manufacturing processes
• Experience troubleshooting manufacturing equipment and process issues
• Exposure to automation systems, controls, sensors, motion systems, or machine integration
• Experience in semiconductor, solar, electronics, or other advanced manufacturing environments

Our Benefits

• Competitive compensation - we want you to grow with us
• Generous, high-quality medical, dental, and vision coverage on day one of employment
• 15 vacation days, 5 sick days, and 10 paid holidays annually - with an extended holiday break at year's end
• 401K with employer match up to 4% of salary
• Employer-paid short-term and long-term disability and employer-sponsored life insurance
• Your work will literally go to space!
