Silicon Photonics Reliability Engineer

Silith; Singapore; Hybrid; SGD 70,000 - 110,000; Full time

Job summary

Silith is seeking a Reliability Engineer to lead qualification and testing for silicon photonics and co-packaged optics products. You will drive failure analysis, reliability modeling, and long-term stability, partnering with design and manufacturing to ensure product durability across lifecycles.

You will own GR-468-based qualification plans, perform HTOL/HTS/TC/THB tests, and develop Weibull models and lifetime predictions, contributing to robust, scalable CPO solutions.

Qualifications

• Bachelor's degree in Electronics, Optoelectronics, Microelectronics, or related fields.
• 3+ years of reliability engineering experience in semiconductor or optoelectronic devices.
• Knowledge of Telcordia GR-468-CORE reliability requirements for optoelectronic devices.
• Experience with reliability tests including HTOL, HTS, TC, THB, HAST, mechanical shock and vibration.

Responsibilities

• Own reliability qualification and QA activities for silicon photonic chips, optical engines, and CPO modules.
• Develop reliability qualification plans, test conditions, acceptance criteria, and validation procedures based on GR-468.
• Execute optoelectronic reliability tests (HTOL, HTS, TC, THB, HAST, SHOCK, VIBRATION).
• Evaluate lifetime reliability of CPO engines and key components (lasers, MZMs, PDs, TIAs).
• Monitor performance during testing (optical power, insertion loss, wavelength shift, BER).
• Perform failure analysis (RCA) and corrective actions per GR-468.
