Position: Embedded Firmware Engineer- Automotive
Years of Experience: 3-8 years
Location: Bengaluru, Karnataka
We are looking for an Embedded Firmware Engineer to design, build, and test production firmware for automotive electronic control units (ECUs). You will work across the full product lifecycle — from device bring-up through validation, manufacturing, and deployment — on microcontroller platforms running real-time operating systems. The role combines hands-on low-level firmware development with system-level diagnostics, self-test, and fault-handling work that keeps safety-critical hardware dependable in the field.
You will collaborate closely with software, hardware, and test engineers, and apply functional safety and diagnostics concepts throughout your work.
-
Design, prototype, implement, and test production embedded firmware for automotive ECUs on 32-bit microcontrollers.
-
Develop and optimize firmware in a real-time operating system (RTOS) environment, managing timing, concurrency, and resource constraints.
-
Build diagnostic and self-test functionality, including power-on self-tests (POST), memory built-in self-tests (BIST), and controlled power-up / go-to-sleep shutdown sequences that meet quiescent-current targets.
-
Implement fault-detection and safe-state handling — for example, monitoring incoming and internal supply voltages, raising diagnostic trouble codes (DTCs), and driving the ECU into a protective reduced-function state on limit violations.
-
Develop CPU-, communication-, and memory-load generation and stress-test functions that can be triggered over CAN, Ethernet, or a diagnostic interface for validation and characterization.
-
Implement and monitor communication interfaces — CAN and Ethernet channels — including link-error, cable-fault, and signal-integrity (CRC) detection, with error logging, reporting, and clear-on-reset behavior.
-
Write firmware to interact with low-level peripherals and buses (SPI, UART, I2C, CAN) and higher-level networking (TCP/UDP) and diagnostics (UDS).
-
Partner with test and platform engineers to build test frameworks and harnesses at unit, integration, and system levels.
-
Debug at the hardware level using standard test equipment, and collaborate across software, hardware, and mechanical teams from bring-up through deployment.
-
Apply functional-safety and security concepts relevant to automotive and autonomous systems throughout design and implementation.
-
3–8 years of hands-on embedded firmware development experience.
-
Expert-level C or C++ for resource-constrained, real-time systems.
-
Strong experience with 32-bit ARM Cortex-M class microcontrollers; familiarity with automotive processors such as the NXP S32G / S32K families.
-
Practical experience with low-level RTOS development (for example, FreeRTOS).
-
Solid grasp of communication protocols across the stack — SPI, UART, I2C, CAN at the low level, TCP/UDP at the high level, and UDS diagnostics.
-
Working knowledge of Python for tooling, automation, and test.
-
Hardware-debugging skills with standard bench equipment (oscilloscope, multimeter, power supply) and basic electrical-engineering fundamentals for low-level debugging.
-
A structured, test-driven approach to firmware quality and the ability to work effectively with hardware and test engineers.
-
Experience with functional safety and process standards — ISO 26262 and ASPICE.
-
Exposure to safety-oriented RTOS variants such as SafeRTOS, and to automotive RTOS / stacks such as QNX, AUTOSAR, or OSEK.
-
Time-synchronization protocols (PTP / IEEE 1588).
-
Device-driver and low-level firmware development experience, including on-chip self-test controllers and memory/logic BIST.
-
Familiarity with automotive diagnostics workflows (DTCs, diagnostic sessions, tester interaction).
You’ll work on firmware that sits at the heart of automotive and autonomous-vehicle platforms, with real ownership over the systems you build and validate. It’s an environment for engineers who like solving hard, low-level problems and seeing their work run on real hardware.
