Job summary

K K Group in Bengaluru seeks an experienced Firmware QA Engineer to plan, execute and improve verification and validation of embedded systems used in wind turbine and industrial environments. You will develop test plans, automation strategies, and evidence for MISRA C compliance, working with firmware, hardware, and quality teams to ensure robust product delivery across unit, integration and system levels.

The role requires 7–10 years of hands-on firmware testing experience, strong embedded

Qualifications

• 7–10 years hands-on 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.
• Understanding of the V-model lifecycle, requirement-based testing, test-case design, defect lifecycle, and release validation.
• Unit, integration, black-box, white-box, and regression testing for embedded systems.
• Awareness of MISRA C guidelines and ability to interpret compliance findings and support closure with firmware developers.
• Experience using Git, Jira, DevOps, or similar.
• Reading schematics and understanding embedded hardware blocks (MCUs, sensors, power supplies, transceivers, interfaces).
• Knowledge of common embedded interfaces (I2C, SPI, UART, CAN, RS485/Modbus, USB, Ethernet).
• Lab instruments experience (oscilloscopes, logic analyzers, multimeters, power supplies, serial terminals, debuggers, 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.
• Good communication and cross-functional collaboration; ability to work with firmware, hardware, systems, quality, production teams.
• Ability to create validation reports, datasheets, application notes, work instructions.

Responsibilities

• Plan, define, and execute firmware V&V strategies for wind turbine and industrial hardware.
• Translate requirements into test plans, specifications, and acceptance criteria.
• Perform V&V across unit, integration, system, regression, and release levels; include manual and automated testing.
• Develop black-box, white-box, boundary, negative, fault-injection, and robustness tests for embedded firmware features.
• Test embedded protocols/interfaces (I2C, SPI, UART, CAN, RS485, Modbus, Ethernet).
• Validate firmware behaviour on target hardware including GPIOs, sensors, timers, and error handling.
• Use static-analysis and code-coverage tools to support MISRA C compliance and evidence generation.
• Analyse results, reproduce issues, perform root cause analysis, and drive corrective actions with cross-functional teams.

Job description

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.

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.
