Opto-Mechanical Engineer — Equity & Photonics Precision

Olix Computing; Greater London; On-site; GBP 90,000 - 120,000; Full time

Job summary

OLIX is seeking an engineer to own the mechanical architecture of photonic subassemblies, including waveguide coupling structures, laser source packaging, and precision alignment fixtures. You will work across CAD to cleanroom, release drawings, supplier corrective action, and collaborate with optical, process and reliability teams to define assembly processes and qualification tests.

A BS/MS in Mechanical or Optical Engineering and 5+ years’ hands-on experience are required, with Creo CAD and

Qualifications

• B.S./M.S. in Mechanical Engineering, Optical Engineering, or closely related field.
• 5+ years hands-on experience designing precision opto-mechanical assemblies for production.
• Proficiency in tolerance stack-up analysis for optical alignment applications.
• Strong knowledge of photonic component packaging (VCSELs, PICs, fiber arrays, waveguide couplers).
• Experience with thermally constrained mechanical design — CTE mismatch analysis, adhesive joint mechanics, and bonded dissimilar-material structures.
• Proficiency in 3D CAD (Creo preferred) with GD&T to ASME Y14.5.
• Familiarity with precision machining, MIM, EDM, laser micromachining, and optical bonding processes.
• Comfort with basic FEA tools for structural and thermal validation
• Green or Black Belt certification preferred

Responsibilities

• Design and develop opto-mechanical assemblies including waveguide coupling structures, photonic interposers, ferrule/connector systems, and precision alignment fixtures.
• Perform tolerance chain analysis (RSS and worst-case) for optical alignment budgets, accounting for thermal excursion, assembly variation, and long-term drift.
• Select and qualify optical-grade materials with consideration for CTE compatibility, outgassing, and process compatibility.
• Lead thermal-mechanical co-design of photonic subassemblies, including heatsink design for ASICs and high-power laser sources.
• Drive DFM/DFA for precision optical assemblies including MIM components, laser-machined features, and bonded/co-cured structures.
• Generate and own GD&T drawings and engineering specifications for optical-grade fabricated parts.
• Collaborate with process engineering, optical design, and reliability teams to define assembly process flows and qualification test plans.
• Support FEA (thermal, structural, modal) for mechanical validation of optical subassemblies.
