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
As an Optical Interconnect Process Engineer at OLIX, you will be responsible for translating optical interconnect architectures into scalable, manufacturable, and reliable hardware. This role focuses on optical packaging, optical alignment, yield, and production readiness for high-density optical systems, and co-packaged optics (CPO). You will work hands-on across prototyping, validation, manufacturing, characterization, and yield, ensuring designs can be built at scale with high performance and reliability.
Responsibilities
Optical Interconnect Implementation
Design and optimise high-density fiber-optic interconnects. Develop fiber-to-chip and fiber-to-package coupling solutions. Develop routing, multiplexing, and signal distribution systems. Define alignment strategies and tolerances for high-volume assembly.
Packaging & Integration
Drive co-packaged optics (CPO) integration at package and system level. Address opto-mechanical constraints including connectors, fixturing, and alignment. Partner with mechanical and thermal teams on integrated system design. Evaluate thermal interactions between ASICs and photonic components.
Process Development & Manufacturing
Develop processes for optical assembly, alignment, and test. Apply Design for Manufacturing (DFM) principles to optical systems. Work with foundries, OSATs, and contract manufacturers Support pilot builds and production ramp.
Yield, Reliability & Validation
Analyze tolerance sensitivities and yield drivers. Investigate variability and resolve production issues. Define and execute validation plans for optical assemblies. Ensure reliability, serviceability, and field-replaceability.
Skills & Experience
Experience in advanced micro-fabrication, with deep process integration expertise.
Experienced collaborating with external fabs, R&D consortia, or tool vendors to develop or transfer new capabilities.
Proven record creating or modifying complete process flows for novel optoelectronic devices.
Background in some of: photolithography, DRIE/RIE, thin-film deposition (PVD/ALD), wafer bonding, or wet etch.
Comfortable switching between hands-on work and high-level process architecture and partner coordination.
Proficient in DOE/SPC tools (JMP, Python, etc.) and disciplined process documentation.
B.Eng./M.Sc/Ph.D. in Materials Science, Electrical/Mechanical Engineering, Physics, or related field.
Excellent communicator; thrives in fast-moving, interdisciplinary environments.
Nice to have
Familiarity with wafer-level packaging or flip-chip integration.
Experience transferring R&D processes to external pilot or production environments.
Working knowledge of simulation and characterisation (FEM, profilometry, interferometry, L-I-V, or spectral testing).
Compensation & Equity
Competitive Salary: Commensurate with your experience, skills, and location

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.
