If you are passionate about advancing a more sustainable future, this is the perfect time to join Enphase!

About the role:

Working in our India-based team, you will lead the Mechanical Engineering testing:  planning, performing, analysing, and reporting of design verification testing. You will perform testing with in-house equipment and at external test labs to complete the testing according to the identified standards and each project’s timeframes.

In addition, you will have close collaboration with our team in China, New Zealand, and USA to execute the tests outside of India.

You will create high-quality reports, and you will have clear spoken and written communication so that our global team can understand the status of testing and any issues arising from test failures.

What you will do:

• Contribute significantly to the development of new electromechanical products, with a focus on testing (60%) and design (40%), working effectively in both solo and team environments.
• Manage assigned mechanical design projects, adhering to project timelines, budget constraints, and quality standards.

• Design and execute comprehensive test plans (Inhouse and external lab) to verify mechanical performance against design specifications, including static and dynamic loading, fatigue testing, environmental testing, and reliability testing.
• Preparing mechanical mock-ups, Prototypes, Electro-mechanical assemblies, Cable Assemblies, and test sample preparation.

• Design parts for plastic injection molding, sheet metal operations, Die casting & extrusion etc.
• Work on connector designs, cable assemblies & ECAD/MCAD integrations.
• Testing proof-of-concepts, prototypes. Finished product for functionality & performance.
• Analyze test data, identify potential issues, and implement design improvements to address any deficiencies.
• Develop and maintain test protocols and documentation.
• Utilize test equipment and instrumentation to collect accurate data (e.g., strain gauges, load cells, data acquisition systems).
• Drive lab space safety, regulatory and security processes compliance.

Failure analysis and root cause identification

• Good exposure on UL/IEC and related standards. Experience on UL1741, IL9540, UL 9540A will be an added advantage.
• Experience in testing below international standards is desirable (but not limited to).
  • Inverters UL 1741, Electrical connectors UL 6703, UL 9703, EN 60512, EN 60352; Polymers UL 94, UL 746C.

• Ingress protection IEC 60529/IPXX/NEMA Enclosure standards
• Experience using computer-aided development tools (SolidWorks)
• Exposure to electrical and electronic testing with knowledge on thermocouple instrumenting and connecting to Data logging equipment for capturing test data.
• Ability to plan, lead and drive the DVT tasks and activities independently with minimal supervision/oversight.
• Hands on Experience on testing Electromechanical products for Design Verification
• Understanding of structural and thermal design considerations.
• Good Exposure on DFX for high volume production.
• Excellent oral, written, and interpersonal communication.
• Understanding of Tolerance stack up & application of GD& T.
• Experience in DFMEA, DFM, RCCA, Mold flow.
• Good exposure to selection of Material (plastic, sheet metal, sealings / gaskets).
• Experience in design and testing of IP rated enclosures.
• Clear communication, verbal and written.
• Experience in the design of high-volume products would be a plus.
• Previous employment in high-power and consumer products industries would be an added advantage.
