hirify.global develops the DX-1 decode accelerator and optical interconnect hardware for AI infrastructure, combining logic, data movement, packaging, optics, and interconnect design.

What you will do

• Design and develop opto-mechanical assemblies, including optical coupling structures, photonic interposers, ferrule and connector systems, and precision alignment fixtures.
• Perform RSS and worst-case tolerance analysis for optical alignment across thermal excursions, assembly variation, and long-term drift.
• Select and qualify optical-grade materials, adhesives, and bonded dissimilar-material structures based on CTE compatibility, outgassing, and process requirements.
• Lead thermal-mechanical co-design for photonic subassemblies, including heatsinks for ASICs and high-power laser sources, and drive DFM/DFA.
• Own GD&T drawings and engineering specifications, collaborating with process, optical design, and reliability engineering teams.
• Support thermal, structural, and modal FEA, environmental stress testing, and failure analysis against relevant optical and telecommunications standards.

Requirements

• B.S. or M.S. in Mechanical Engineering, Optical Engineering, or a closely related field.
• 5+ years of hands-on experience designing precision opto-mechanical assemblies for production.
• Experience with tolerance stack-up analysis, photonic component packaging, laser sources, PICs, fiber arrays, and optical couplers.
• Experience with CTE mismatch analysis, adhesive joint mechanics, and thermally constrained mechanical design.
• Proficiency in 3D CAD, preferably Creo, and GD&T according to ASME Y14.5; familiarity with precision machining, MIM, EDM, laser micromachining, and optical bonding.
• Eligibility is subject to U.S. export control regulations and recent citizenship or permanent residency status; applicants with recent citizenship or permanent residence in restricted countries may be ineligible.

Nice to have

• Experience with OCP standards and rack design.
• Green or Black Belt certification.
