Senior Process Integration Engineer - Core Technology
About OLIX
--------------
AI is growing faster than any technology in history and the explosion in demand has created a massive infrastructure gap; we can no longer build chips or power stations fast enough to keep up. The industry is still leaning on a ten\-year\-old hardware blueprint that has reached its limit. A new paradigm that is faster and more efficient will be the biggest economic opportunity of the next century and create the most important company of the next decade. The OLIX Decode Accelerator 1 (DX\-1\) is the first accelerator architected specifically for decode. Rack\-scale co\-design of logic, data movement, packaging, optics and interconnect enables a step change in system level performance.
The Role
------------
We’re looking for a Senior Process Integration Engineer to design and implement bespoke fabrication flows for advanced optoelectronic devices. You’ll bridge the gap between R\&D concepts and manufacturable reality, building, iterating, and qualifying custom process sequences that underpin our next\-generation hardware. This role combines hands\-on technical depth with strategic process integration oversight. You’ll spend time both in the cleanroom developing new flows and outside it, collaborating with partner fabs, R\&D institutes, and equipment suppliers to push process capability forward.
Responsibilities
--------------------
- Custom process flow development – architect, prototype, and refine fabrication flows across silicon, glass, or compound substrates for VCSELs and optoelectronic structures.
- Process Transfer – You'll own the transfer of our processes from internal development into a III\-V foundry partner, qualifying the flow end\-to\-end.
- Rapid prototyping \& iteration – drive fast cycles from CAD to measured die, identifying and optimising key process levers.
- Process definition \& scale\-up – document mask sets, material stacks, and dependencies; mature experimental flows into repeatable, pilot\-ready documentation.
- External collaboration – work directly with R\&D partners, universities, and external foundries to qualify new process steps, tools, and materials.
- Strategic oversight – guide internal technicians and external partners, ensuring process discipline, yield learning, and structured design feedback.
- Data\-driven optimisation – use DOE/SPC and metrology data to accelerate convergence and maintain process control.
- Knowledge capture \& review – maintain detailed process documentation; run internal reviews and FMEA sessions.
------------------------
- PhD or Master's in Optics, Photonics, Mechanical Engineering, or related field
- 6\-10\+ years of experience in optical hardware, packaging, or manufacturing
- Strong experience with fiber optics, waveguides, and coupling techniques
- Experience with optical packaging and alignment at scale
- Understanding of tolerance analysis and yield optimization
- Hands\-on experience with lab validation, prototyping, and build processes
- Experience working with manufacturing partners (foundries, OSATs, CM)
- Familiarity with CPO or high\-density optical packaging is strongly preferred
- Experience with processing and characterizing optical fibers and glass core substrates.
--------------------------
- Competitive Salary: Commensurate with your experience, skills, and location
- Equity \& Ownership: Meaningful stock options. You’re not just joining the mission; you’re owning a piece of it
- Proximity Bonus: We value your time. To minimise your commute and maximise your life, we offer an annual Living\-Local Bonus if your residence is within 20 minutes of the office
- Retirement Benefits:Employer\-contributed retirement plans to help you build long\-term financial security.
