Job summary

Lyte is seeking a Hardware Reliability Test Engineer to own environmental and durability qualification for LyteVision modules and the LyteCore SoC, including HALT/HASS programs and failure analysis. This hands-on role requires running chambers in lab and translating results into field-life predictions.

You will build test plans for vibration, thermal cycling, humidity, dust, EMI/EMC, and IP-related validation, while contributing reliability considerations early in new designs and maintaining

Qualifications

• 2–4 years of hardware reliability engineering, environmental/test qualification, or product qualification, ideally in sensors/optics/consumer electronics/auto-grade hardware.
• Hands-on experience with HALT/HASS chambers, vibration tables, and thermal chambers.
• Knowledge of reliability statistics (MTBF/MTTF, Weibull) and accelerated life testing models (Arrhenius, Coffin–Manson).
• Experience with failure analysis or close collaboration with FA labs.
• Familiarity with MIL-STD-810, IEC 60068-2, IPC/JEDEC, ISO 16750, or automotive/industrial standards.

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, 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.
• Lead failure analysis on units that fail in test or field, coordinating with silicon, optics, and mechanical teams.
• Own reliability test fixtures and chamber infrastructure; collaborate with contract labs when needed.
• Contribute reliability requirements and DFR input into new module/PCB designs with hardware and silicon teams.
• Maintain test documentation, qualification reports, and traceability for customer/regulatory review.
• Support functional safety and durability claims for robotics, automotive-adjacent, and industrial deployment.

Job description

About the role

• 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
• 401(k) retirement plan
• Flexible vacation and time‑off policy
• Collaborative, fast‑paced, and inclusive work environment
• Opportunity to work oncutting‑edgetechnologies with a highly cross‑functional team
