About the role
Key Responsibilities
Test Strategy & Execution
- Formulate validation plans, comprehensive test specifications, matrices,
and protocols aligned with hardware and firmware requirements.
- Conduct hands-on testing including functional, Metrology, Tamper,
Environmental, Reliability, and Communication protocol testing.
- Replicate filed issues and customer complaints in the lab environment to
support R&D in root-cause analysis.
- Develop test benches and automated test setups using scripts or software
like Python, LabVIEW.
- Map testing protocols directly to applicable Indian Standards (IS 16444, IS
13779, IS 15959 part 1, 2 & 3).
- Oversee DLMS/COSEM compliance testing, companion standard testing,
and data exchanges with Head End Systems (HES) and MDM.
- Lead certification efforts by coordinating with third-party Indian testing
laboratories like CPRI and ERDA.
- Ensure data security compliance by validating cryptographic functions,
secure boot operations, and rollouts of firmware over-the-air (FOTA).
- Generate technical test reports, clear defect logs, and final validation
summary reports for management review.
- Maintain traceability matrices that link engineering requirements directly
to validated test outcomes.
- Review user manuals, product datasheets, and technical documentation to
ensure layout matches operational reality.
