Senior Manufacturing Process Engineer (Mfg Waferfab)
We value our talented employees, and whenever possible strive to help one of our associates grow professionally before recruiting new talent to our open positions. If you think the open position you see is right for you, we encourage you to apply!
Our people make all the difference in our success.
We are seeking a bright Process Engineering professional to join our talented team in our San Jose Fab. If you have a passion for learning and solving problems as well as an educational background that includes materials science, physics, electrical engineering or directly related disciplines; or hands-on experience that includes wafer fabrication process and equipment; -- this role could be just what you seek.
What Will You Do
This role involves developing and maintaining processes for the fabrication of compound semiconductor wafers. It requires close collaboration with cross-functional teams in Process Development, Integration, and Product Engineering to ensure the seamless transfer of advanced processes into production. Additionally, this position will support the Product Engineering team with First Pass Yield and Failure Analysis to enhance the performance and yield of photonic devices. A strong understanding and practical experience in wafer fab processing are crucial, particularly in Photolithography and Plating, as well as in Sputtering thin film deposition, RIE, PECVD, and Wet Etch.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
