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.
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.
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 polymer optical waveguides
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.
Due to U.S. export control regulations, candidates’ eligibility to work at OLIX depends on their most recent citizenship or permanent residency status. We are generally unable to consider applicants whose most recent citizenship or permanent residence is in certain restricted countries (currently including Iran, North Korea, Syria, Cuba, Russia, Belarus, China, Hong Kong, Macau, and Venezuela). Applicants who have subsequently obtained citizenship or permanent residency in another country not subject to these restrictions may still be eligible.
