Job Title: Lead – Test & Validation Engineer.
Position Overview:
We are looking for a highly skilled and experienced Test & Validation Engineer to contribute to the verification, validation, and qualification of embedded firmware used in products/solutions across our product portfolio. The ideal candidate will have a strong understanding of firmware validation methodologies, test system development, reliability testing, and compliance standards. This role demands technical thoroughness, analytical problem-solving skills, and the ability to collaborate across multidisciplinary teams to ensure robust, reliable, and compliant electronic products.
Key Responsibilities:
- Plan, define, and execute firmware verification and validation (V&V) strategies for monitoring and control hardware used in wind turbine and industrial environments.
- Analyse firmware, system, and product requirements and translate them into clear test plans, test specifications, test cases, validation protocols, acceptance criteria, and requirement traceability.
- Perform firmware verification and validation across unit, integration, system, regression, and release-validation levels, including both manual and automated test execution.
- Develop and execute black-box, white-box, boundary, negative, fault-injection, and robustness tests for embedded firmware features and state machines.
- Test embedded protocols and interfaces such as I2C, SPI, UART, CAN, RS485, Modbus, Ethernet, and service/debug interfaces as applicable to the product.
- Validate firmware behaviour on target hardware including GPIOs, ADC/DAC paths, sensors, timers, communication interfaces, boot behaviour, self-test routines, and error handling.
- Use static-analysis and code-coverage tools to support MISRA C compliance, code-quality checks, and evidence generation for reviews and audits.
- Analyse test results and failures, collect logs and measurements, reproduce issues, perform root cause analysis, and drive corrective actions with firmware, hardware, design, manufacturing, and quality teams.
- Develop and maintain reusable test scripts, automated regression setups, HIL/test benches, and result-reporting workflows using Python, Bash, Robot Framework, or similar tools.
- Maintain test plans, test cases, test results, defect reports, validation summaries, release evidence, and lessons learned.
- Collaborate with cross-functional teams including hardware design, firmware, mechanical, quality, production engineering, and manufacturing teams.
- Support NPI (New Product Introduction) builds, pilot runs, and field validation activities.
- Participate in continuous improvement of test methodologies, automation frameworks, validation processes, design review practices, tools, and KK's way of working.
- Contribute to technology development, product innovation, and competency development through knowledge sharing, reviews, and support to colleagues when needed.
Must Have Skills & Experience:
- Around 7–10 years of hands-on experience in firmware testing and validation of embedded systems.
- Hands-on experience with embedded C, C++, Embedded Linux, firmware debugging on target hardware, and validation of embedded firmware behaviour.
- Good understanding of the V-model lifecycle, requirement-based testing, test-case design, defect lifecycle, and release validation.
- Hands-on experience with unit, integration, black-box, white-box, and regression testing for embedded systems.
- Awareness of MISRA C guidelines and ability to interpret common compliance findings and support closure with firmware developers.
- Experience using version control and issue-tracking tools such as Git, Jira, DevOps, or similar platforms.
- Basic ability to read schematics and understand embedded hardware blocks such as microcontrollers, sensors, power supplies, communication transceivers, and interface circuits.
- Good knowledge of common embedded interfaces such as I2C, SPI, UART, CAN, RS485/Modbus, USB, and Ethernet.
- Hands-on experience with lab instruments such as oscilloscopes, logic analysers, multimeters, power supplies, serial terminals, debuggers, and protocol logs.
- Experience with HIL systems, sensor simulation, automated test benches, environmental test support, or remote validation setups.
- Strong problem-solving, debugging, and root cause analysis skills.
- Good communication, documentation, and cross-functional collaboration skills, with the ability to work with firmware, hardware, systems, quality, and production teams.
- Ability to create clear technical documentation, including validation reports, datasheets, application notes, and work instructions.
Good to Have Skills & Experience:
- Experience with wind turbine subsystems, condition monitoring systems (CMS), SCADA interfaces, or industrial automation hardware.
- Familiarity with embedded Linux basics, RTOS concepts, bootloader behavior, firmware upgrade flows, secure boot concepts, or OTA/update validation.
- Exposure to condition monitoring, vibration sensing, data acquisition systems, industrial control systems, or renewable-energy applications.
- Basic knowledge of EMC/ESD, environmental, reliability, and certification test support as it relates to firmware behavior and system robustness.
- Prior experience in a regulated domain (e.g., wind, automotive, industrial and backup products).
Academic Qualifications:
- Bachelor's degree (mandatory) – B.E./B.Tech in Electronics, Electrical & Electronics or Related Fields.
Soft Skills:
- Strong problem-solving and analytical skills.
- Excellent communication and cross-functional collaboration skills.
- Proactive attitude and ability to work independently or in a team.
- Strong documentation skills.
What We Offer:
- A challenging and rewarding role in a pioneering company dedicated to renewable energy.
- Opportunities for professional growth and career advancement.
- A collaborative and inclusive work environment.
