Sr Firmware Developer

About the Role

We are looking for an experienced Embedded Software Engineer with strong, hands-on firmware development skills on 32-bit microcontroller platforms. We are hiring for capability rather than for a single pre-defined slot. Across all of our programs the underlying work is the same: production-quality embedded C, close to the hardware, with real responsibility for correctness and reliability. This is a hands-on engineering role at a senior level.

What You Will Do

• Key Responsibilities
• • Design, develop, test and maintain production embedded firmware in C on 32-bit microcontrollers.
• • Develop device drivers and low-level peripheral software — SPI, I2C, UART, CAN / CAN-FD, Ethernet, USB, ADC, PWM, timers, DMA, GPIO and watchdog.
• • Define software architecture for assigned modules: layering, task partitioning, scheduling, state machines, timing budgets and interface contracts.
• • Develop RTOS-based and bare-metal applications with attention to real-time behaviour, determinism and resource constraints.
• • Implement communication protocol stacks and application protocol layers, and integrate third-party stacks and middleware.
• • Debug at system level using oscilloscopes, logic analysers, JTAG/SWD debuggers, protocol analysers and trace tools — including intermittent, timing and memory-related faults.
• • Write unit and integration tests, support validation on test benches and Hardware-in-the-Loop setups, and reproduce and close out field issues.
• • Author and maintain engineering documentation under a controlled process: software requirement specifications, design documents, interface specifications, test cases and traceability.
• • Review code and designs from other engineers, and set and enforce coding and quality standards.
• • Mentor junior and mid-level engineers on embedded practice and debugging discipline.
• • Work closely with hardware engineers on schematic reviews and hardware/software integration, and support customer technical discussions and effort estimation.

What We’re Looking For

• Required Skills and Experience
• • B.E./B.Tech or M.E./M.Tech in Electronics, Electrical, Instrumentation, Computer Science, Embedded Systems or a related discipline.
• • 8+ years of hands-on embedded firmware development in C, with demonstrated ownership of modules or subsystems taken through to production.
• • Strong practical experience on 32-bit microcontrollers — ARM Cortex-M or Cortex-R class (TI, ST, NXP, Renesas, Microchip or equivalent). This is essential; the role is not suited to candidates whose experience is primarily 8/16-bit or application-layer only.
• • Solid embedded fundamentals: interrupts, timers, DMA, memory maps, linker scripts, startup code, stack and heap behaviour, bootloaders, and RTOS concepts and real-time scheduling.
• • Register-level and protocol-level command of at least SPI, I2C, UART and CAN / CAN-FD.
• • Ability to read schematics and device datasheets independently and translate them into working driver code.
• • Proven debugging ability at board level using oscilloscope, logic analyser and JTAG/SWD debugger.
• • Experience working to a documented development process with requirements, design records, reviews and traceability.
• • Version control (Git), code review and structured development practices.
• • Clear technical writing and spoken English — our documentation and design reviews are customer-facing.
