Job summary

Lyte AI Inc. is seeking a Hardware Reliability Test Engineer to own environmental and durability qualification for LyteVision modules and the LyteCore SoC family.

You’ll run HALT/HASS tests, build plans for vibration, thermal cycling, humidity, dust, EMI/EMC, and lead root-cause analyses with hardware and silicon teams. You’ll model accelerated life tests and translate chamber results into MTBF/MTTF forecasts while maintaining rigorous test documentation for regulatory and customer reviews.

Qualifications

• 2–4 years in hardware reliability engineering, environmental test engineering, or product qualification.
• Hands-on experience with HALT/HASS chambers, vibration tables, and thermal chambers.
• Working knowledge of reliability statistics: MTBF/MTTF, Weibull, Arrhenius, Coffin-Manson.
• Experience with failure analysis techniques or close partnership with FA labs.
• Familiarity with MIL-STD-810, IEC 60068-2, IPC/JEDEC, ISO 16750, or automotive/industrial equivalents.
• Bachelor's or master's degree in mechanical engineering, Electrical Engineering, Materials Science, or a related field.
• Strong instincts for root-causing ambiguous failures and communicating findings clearly to cross-functional hardware and silicon teams.

Responsibilities

• Design, execute, and analyze HALT and HASS programs for LyteVision modules and subassemblies.
• Build and run test plans for vibration, mechanical shock, thermal cycling, thermal shock, humidity/condensation, dust/ingress, and EMI/EMC.
• Characterize optical and sensor performance drift under environmental stress.
• Define accelerated life test models and translate chamber results into field-life reliability predictions (MTBF/MTTF, Weibull).
• Lead failure analysis on units that fail in test or in the field and coordinate with silicon, optics, and mechanical teams to drive root cause and corrective action.
• Own reliability test fixtures and chamber infrastructure; work with contract labs when internal capacity is constrained.
• Contribute reliability requirements and DFR input early into new module and PCB designs, alongside hardware and silicon teams.
• Maintain test documentation, qualification reports, and traceability suitable for customer and regulatory review.
• Support functional safety and durability claims for robotics, automotive-adjacent, and industrial deployment environments.

Job description

We're looking for a Hardware Reliability Test Engineer to own environmental and durability qualification for LyteVision modules and the custom silicon inside them (LyteCore SoC, analog front-end, laser control chip). You'll design and run the test programs that prove our sensors survive vibration, thermal cycling, humidity, shock, and years of field duty — and you'll turn failures into root causes the design team can act on. This is a hands-on role: you'll be in the lab running HALT/HASS chambers as often as you're in front of a laptop analyzing failure data.

What you'll do

• Design, execute, and analyze HALT (Highly Accelerated Life Testing) and HASS (Highly Accelerated Stress Screening) programs for LyteVision modules and subassemblies .
• Build and run test plans for vibration, mechanical shock, thermal cycling, thermal shock, humidity/condensation, dust/ingress (IP rating validation), and EMI/EMC .
• Characterize optical and sensor performance drift under environmental stress .
• Define accelerated life test models and translate chamber results into field-life reliability predictions (e.g., MTBF/MTTF estimates, Weibull analysis) .
• Lead failure analysis (FA) on units that fail in test or in the field — coordinate with silicon, optics, and mechanical teams to drive root cause and corrective action .
• Own reliability test fixtures and chamber infrastructure; work with contract labs when internal capacity is constrained .
• Contribute reliability requirements and DFR (Design for Reliability) input early into new module and PCB designs, alongside the hardware and silicon teams .
• Maintain test documentation, qualification reports, and traceability suitable for customer and regulatory review .
• Support functional safety and durability claims for robotics, automotive-adjacent, and industrial deployment environments .

Required Qualifications

• 2–4 years of experience in hardware reliability engineering, environmental test engineering, or product qualification — ideally on sensors, optics, consumer electronics, or automotive-grade hardware .
• Hands-on experience running HALT/HASS chambers, vibration tables, and thermal chambers .
• Working knowledge of reliability statistics: MTBF/MTTF, Weibull analysis, accelerated life testing models (Arrhenius, Coffin-Manson, etc.)
• Experience with failure analysis techniques or close partnership with FA labs .
• Familiarity with relevant standards (e.g., MIL-STD-810, IEC 60068-2, IPC/JEDEC, ISO 16750, or automotive/industrial equivalents) .
• Comfort working with optical or MEMS-based sensing hardware, or strong appetite to learn — our modules combine photonics, analog electronics, and custom silicon .
• Bachelor's or master's degree in mechanical engineering, Electrical Engineering, Materials Science, or a related field .
• Strong instincts for root-causing ambiguous failures and communicating findings clearly to cross-functional hardware and silicon teams .

Preferred Qualifications

• Experience testing sensor modules for robotics, AMRs, or autonomous vehicle platforms
• Exposure to functional safety processes (ISO 26262 or similar)
• Experience working with contract manufacturers or OSAT partners on qualification builds

Benefits (subject to location and local regulations)

• Competitive salary and equity
• Comprehensive medical, dental, and vision coverage
• Flexible vacation and time‑off policy
• Collaborative, fast‑paced, and inclusive work environment
• Opportunity to work oncutting-edgetechnologies with a highly cross‑functional team
