Job Description
Job Description:
Nextracker is seeking a highly motivated and detail-oriented Sr Reliability EngineerPower Electronics & Electricalto join our Reliability this role you will drive the reliability robustness and long-term performance of our power electronics and electrical cabling products throughout their lifecyclefrom concept and design to testing and deployment. This role merges rigorous design reliability practices with hands-on validation and failure analysis in a fast-paced cross-functional environment.
Key Responsibilities:
- Design for Reliability: Implement advanced DfR methodologies to proactively mitigate potential failure modes in high-voltage and power electronic systems. Perform component derating analysis thermal/mechanical stress evaluations and ensure compliance with standards (JEDEC IEC UL). Conduct DFMECA and Fault Tree Analysis and own the reliability requirements definition and tracking.
- Testing & Validation: Lead and define HALT/HASS testing protocols to expose early-life and latent design weaknesses. Develop and execute accelerated life testing (ALT) strategies across electrical thermal and mechanical domains aligned with real-world usage profiles. Perform hands-on power converter validation (step load testing power cycling vibration testing etc.) using lab instrumentation (oscilloscopes spectrum analyzers etc.).
- Failure Analysis & Corrective Action: Investigate failures in design validation and field environments using advanced techniques such as SEM/EDS X-ray FTIR and dye/pry methods. Coordinate internal and third-party failure analysis efforts and drive implementation of corrective and preventive actions. Design tests needed to verify failure mode and see through implementation of corrective actions and solutions.
- Simulation & Modeling: Use LT Spice OrCAD and simulation tools to analyze and validate circuit behavior under stress. Perform reliability prediction and modeling using tools such as ANSYS RAM Commander ReliaSoft and Windchill.
- Cross-Functional Collaboration: Partner with design test and supplier engineering teams to ensure reliability targets are met throughout development cycles. Serve as the technical leader in reliability risk reviews and design validation gates. Responsible for communicating progress through presentations and technical reports to management.
Qualifications:
- Bachelors or Masters degree in Electrical Engineering Power Electronics or a related field. Masters degree preferred
- Proven experience (7 years) working with high voltage systems high power electronics and DC-DC converters preferably in renewable power electronics electric vehicle or industrial power systems.
- Experience with reliability standards and analysis methods: DFMEA MTBF FIT ALT HALT and HASS. Background in Ansys Sherlock Physics of failure principles and failure rate predictions based on stress factors like vibration shock temperature cycling and thermal gradients.
- Knowledge of industry standards and certifications for power electronics including IEC UL JEDEC and IEEE.
Preferred Qualifications:
- Knowledge of Physics of Failure principles Weibull life data analysis and stress-based modeling techniques.
- Experience with PCBA-level derating analysis and reliability assessments for data center or energy infrastructure applications.
- Hands-on lab skills with electrical thermal and vibration test environments. Experience with Insulation Resistance Dielectric Withstand and environmental testing for PV cabling connectors and polymer overmolds.
- Familiarity with reliability planning for product field deployment and field return data analysis.
