Now we’re looking for more thinkers, doers, builders, and makers to join us. People who’ll bring new perspectives, solve tough problems, and thrive as part of a team.
If that’s you and this role fits, we want to hear from you.
Join the power movement as a Senior Equipment Engineer - R&D Vacuum Deposition
We’re looking for a hands-on Equipment Engineer to join our R&D team and help build the next generation of thin-film deposition technology. The Equipment Engineer will be responsible for supporting, maintaining, and improving high-vacuum systems used in R&D and operations. This role requires strong technical expertise, procedural discipline, and the ability to collaborate across engineering and operations functions to ensure safe, reliable, and high-performance equipment operation. If you enjoy working on complex equipment, mentoring others, and solving problems in a collaborative, fast-paced environment, this is your opportunity to make an impact.
What you'll do:
- Lead installation, startup, commissioning, and qualification of systems, including vendor factory acceptance testing (FAT)
- Develop and maintain procedures including SOPs, PM schedules, and LOTO documentation in compliance with OSHA, SEMI, and internal standards
- Train and mentor equipment technicians in safe operation, troubleshooting, and preventive maintenance of deposition tools
- Collaborate with process engineers, design engineers, and facilities teams to drive improvements in equipment performance, reliability, and integration
- Perform root cause analysis and corrective actions for complex equipment issues
- Implement upgrades, retrofits, and reliability improvements with coordination across vendors and internal stakeholders
- Track equipment uptime, maintenance history, and performance metrics for continuous improvement
- Ensure strict adherence to safety standards and support EHS initiatives
What we’re looking for:
- Bachelor’s degree in Mechanical, Electrical, Materials, or related engineering field (or equivalent practical experience)
- 5+ years of experience with semiconductor or thin-film deposition equipment
- Strong background in vacuum systems (HV/UHV), pumps (roughing, turbo, cryo), gauges, and leak detection
- Demonstrated ability to write and implement procedures (SOPs, PMs, LOTO)
- Hands-on experience with equipment startup, commissioning, and qualification
- Proven ability to train and support technical staff
- Effective cross-functional communicator with strong troubleshooting skills
- Commitment to safety, reliability, and documentation discipline
Bonus points for:
- Experience in R&D environments
- Experience with magnetron sources (thermal or e-beam), and high-vacuum chamber design
- Familiarity with process gases, cryogenics, or thermal control systems
- Knowledge of automation platforms (Beckhoff, Siemens) or data acquisition systems
- Proficiency with CAD (NX preferred) or basic design review capability
- Prior experience in FAT/SAT processes and vendor equipment qualification
- Prior success building first-of-kind or experimental tools for material science or semiconductor R&D
Must-have Requirements:
- Ability to occasionally lift up to 50 lbs
- Perform activities such as stooping, climbing, standing, or sitting for extended periods of time
- Dedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, and cryogenics
- Willingness to travel or work required nights/weekends/on-call occasionally
