Optimize process performance through statistical process control (SPC) and lead OEM work inspection development integration with urgency.
Support technology transfer from development to high-volume manufacturing, ensuring processes are robust, repeatable, and scalable.
Partner with cross-functional teams, including core equipment engineering, material procurement, and manufacturing operations to meet cell efficiency and production targets.
Who You Are
Experienced working in a cleanroom setting.
Driven by a strong understanding of thermodynamics, transport phenomena, vacuum systems, electron-hole physics (Hall effect), and thin film characteristics.
Deep experience working with high-temperature (500 °C+), high-volume manufacturing equipment with silicon or glass material inputs.
Comfortable with chemical characterization, including crystal lattice chemistry, quantum field effects, and the principles of oxidation/reduction in gaseous environments, particularly as applied to photon-electron interfaces.
Experienced with III-V, GaAs, PERC, TOPCon, or other silicon-based solar cells.
Data-driven in your approach to process development and troubleshooting — you let the numbers lead.
Able to work effectively in a fast-moving fab environment where priorities shift and deadlines are real.
A strong collaborator who can work across engineering disciplines and communicate technical findings clearly to varied audiences.
Energized by the challenge of building something new and scaling it to high-volume production.
Qualifications
Bachelor's degree or higher in Chemical Engineering, Materials Science, Electrical Engineering, Physics, or a related field.
5+ years of process engineering experience in semiconductor, photovoltaic, or advanced manufacturing environments.
Hands-on experience with high-temperature diffusion toolsets.
Strong working knowledge of ion implantation processes and diffusion thermal tools.
Experience with DOE methodology, statistical process control (SPC), micron-level physical inspection, and optical/electrical characterization.
Proficiency with Python, SQL, JMP, and Excel for process monitoring and optimization.
Strong documentation skills and experience reviewing P&IDs, leading change order processes, writing SOPs, process specs, and engineering reports.
Ability to support a fab environment, including occasional travel to the Wilmer, TX G2 facility as needed.
About T1 Energy
At T1 Energy (NYSE: TE), we build energy. We are an American solar manufacturer building the future of energy abundance. From our headquarters in Austin, Texas, we’re pioneering a domestic solar supply chain with one mission: to invigorate America with scalable, reliable, and low-cost energy.
We started with G1_Dallas, one of the most advanced solar manufacturing facilities in the world. The 5GW facility is located in Wilmer, Texas. It has the capacity to produce more than 20,000 solar modules a day for solar farms that power American homes, businesses, and keep our energy grids resilient.
Next is G2_Austin: Our new solar cell fab in Rockdale, Texas. Its first 2.1GW phase is designed to produce next-generation TOPCon cells beginning in 2027. As the fab grows, it’s expected to support up to 1,800 manufacturing jobs. Modules assembled at G1 can run on cells from G2.
What comes after G2? Come join us and help figure that out. And then build it. The sun has always shone on America. Now you can turn it into abundant electricity.
The T1 Way
We’re all in on the mission, and we pursue it as one team. We move fast, own our results, and treat each other with respect. Egos stay at the door: no one is too senior to roll up their sleeves, and no idea is too small to share. Be sharp, be honest, be human. If you can hold the line and keep a sense of humor, you’ll fit right in.
T1 Energy is an Equal Opportunity Employer. We are committed to creating an inclusive environment for all employees and applicants and do not discriminate on the basis of any legally protected characteristics.
