Process Engineer - Photolithography

The Company:

Solestial, Inc. is the solar energy company for space. Solestial’s core technology is a breakthrough ultra-thin silicon solar cell that can self-cure radiation damage at normal operating temperatures in space, packaged in a flexible, lightweight panel designed to achieve minimum degradation for up to 10 years in LEO. Solestial panels can be mass-produced using automated machines resulting in costs 90% lower than incumbent technologies, with virtually unlimited manufacturing capacity. From today’s satellite constellations and research projects to tomorrow’s utility-scale energy infrastructure and services in space, Solestial is powering the new space economy.

The Role:

As a Photolithography Process Engineer you will be the owner of photoresist patterning (photoresist deposition, curing, UV exposure and development) at Solestial R&D line and will transition photoresist patterning processes to a new mass production line. This will include running baseline production lots, running SPC and troubleshooting tool failures, developing new patterning processes, transferring R&D photoresist patterning processes to large-scale manufacturing tools, developing SOPs and training operators.

This is an exciting position as part of a positive, supportive, and passionate team! A competitive compensation package, including equity and full benefits (see below), will be offered.

Specific Responsibilities to Include:

• Analyze characterization data and present to the technical team.
• Run baseline photoresist patterning recipes for pilot production lots.
• Develop new photoresist patterning processes to improve characteristics of the solar cells.
• Follow safety requirements and prevent accidents.
• Work in close collaboration with sputtering and electroplating engineers as well as solar cell engineers to improve the performance of photoresist patterning.
• Transition photoresist patterning processes to large scale production tools.
• Maintain clean work environment
• Characterize the formed photoresist masks (optical microscopy, profilometry, SEM).
• Develop new technological equipment to improve photoresist patterning quality.
• Train tool operators.
• Troubleshoot the issues with the tools and work with equipment technicians on mitigation.

Your Background:

• Ability to work in a dynamic environment.
• Bachelor degree in Engineering, Materials Science, Physics or related fields.
• Positive attitude.
• Ability to work in a class 1,000 clean room environment.
• Previous experience with photolithography (solar cells, PCBs or ICs) is a strong plus.
• Ability to occasionally conduct wet etching wearing the necessary PPE.
• Strong analytical skills, basic data analysis and presentation, clear communication.

Our Benefits:

• A minimum of 15 days PTO and 10 paid holidays annually
• Generous, high-quality medical, dental and vision coverage on day one of employment
• Employer-paid short-term and long-term disability and employer-sponsored life insurance
• 401K with employer match up to 4% of salary
