Purpose: The Staff Reliability Engineer owns the reliability, safety, and long‑term performance of advanced laser‑based surgical treatment equipment, including ultrafast laser sources, optical delivery subsystems, precision mechatronics, control electronics, and embedded software. This role requires deep expertise in reliability engineering for laser/optics, complex electromechanical systems, and medical device regulatory standards. The engineer will define, lead, and execute the reliability strategy across the entire product lifecycle—from system architecture through field performance.

You will:

• Define system‑level reliability plans, safety requirements, and verification strategies.
• Evaluate system architecture and safety mechanisms (shutters, interlocks, redundant sensors, watchdogs, and closed‑loop energy/position control, etc)
• Validate alignment robustness and optical performance under vibration, thermal cycling, and shock.
• Characterize long‑term beam quality, optical power stability, and dose‑delivery reliability.
• Perform WCCA (Worst‑Case Circuit Analysis), component derating, and EMC reliability assessments per relevant standards.
• Model long‑term mechanical degradation such as wear, thermal drift, bearing/flexure fatigue, and mechanical reliability limits.
• Analyze firmware failure modes impacting laser firing logic, sensing, UI behavior, real‑time control loops, and safety systems.
• Develop physics‑of‑failure and accelerated life models across optical, electrical, mechanical, and software subsystems.
• Perform Weibull analyses, lifetime prediction modeling, and reliability growth modeling.
• Create and execute comprehensive qualification plans (e.g., laser aging/lifetime, HALT/HASS, thermal & humidity cycling, vibration & shock, contamination/particulate sensitivity).
• Ensure compliance with ISO 13485 and associated medical device reliability requirements.
• Collaborate with optical, electrical, mechanical, software, manufacturing, quality, and regulatory engineering teams to prioritize and resolve reliability risks.
• Guide internal teams and external partners in reliability engineering best practices and medical device development processes.
• Monitor field metrics such as MTBF, service logs, system usage hours, and calibration/maintenance trends.
• Lead 8D investigations, physics‑of‑failure (PoF) analyses, and cross‑functional root cause investigations.
• Drive corrective actions, design improvements, and long‑term reliability growth initiatives.

Qualifications

Required:

• BS/MS in Reliability Engineering, Optical Engineering, Mechanical Engineering, Electrical Engineering, Systems Engineering, Physics, or related field.
• 8+ years of hands‑on reliability engineering experience for complex electro‑optical‑mechanical systems.
• Practical experience with FMEA, HALT/HASS, accelerated life modeling, and Weibull/statistical reliability analysis.
• Demonstrated ability to developing and executing qualification test plans and interpreting results for both new product development and on-market products.
• Proficiency with reliability analysis and data tools such as Minitab, JMP, Python, MATLAB, etc.
• Proven track record and ability to lead cross‑disciplinary teams to deliver reliability engineering tasks and improve the product quality on schedule.

Preferred:

• Reliability engineering certification (ASQ CRE or equivalent).
• Strong knowledge of medical device standards, including:
  • ISO 14971 (Risk Management)
  • IEC 60601‑1 (Medical Electrical Safety)
  • IEC 60601‑1‑2 (EMC)
  • IEC 60825 (Laser Safety)
  • IEC 62304 (Software Lifecycle)

• Experience with surgical or therapeutic laser systems, ultrafast lasers, and optical delivery design.
• Experience with field reliability programs and servicing strategies for regulated devices.
