AUTOSAR BSW Engineer

Tata Technologies; Auburn Hills (MI); On-site; USD 100,000 - 140,000; Full time

Job summary

Tata Technologies is seeking an experienced embedded software engineer to develop and integrate core software for gasoline ECM/PCM using Infineon AURIX TC3xx. You will work on AUTOSAR BSW foundation, ECU bring-up, and multi-core timing, with a focus on safety mechanisms and robust diagnostics.

You will configure and validate hardware/software interfaces, perform root-cause analysis, and collaborate with calibration, safety, and hardware teams during integration and validation.

Qualifications

• Strong Embedded C with microcontroller-level debugging.
• AUTOSAR BSW integration and CDD development experience.
• Infineon AURIX TC3xx (TC38x) experience — startup, memory map, interrupt architecture.
• Knowledge of MCU safety concepts — SMU, MPU, watchdogs, multi-core OS.
• ECM/PCM gasoline engine control software experience with cam/crank sensing and spark/injector actuation.
• Proficiency with Trace32 and INCA; defect triaging and RCA discipline.

Responsibilities

• Integrate and configure core AUTOSAR BSW — OS, RTE, EcuM, BswM, MemStack (NvM/Fee), Diagnostics (Dcm/Dem), IoHwAb, Watchdog stack.
• Implement ECU startup/shutdown sequencing, mode transitions, wake-up/sleep handling, and NVM block design with crash-safe writes and data recovery.
• Configure multi-core AUTOSAR OS — tasks, alarms, ISRs, spinlocks, IOC inter-core communication, and CPU load/timing optimization.
• Configure and validate MCU safety mechanisms — SMU alarms and fault reactions, MPU-based memory partitioning/FFI, windowed and watchdog supervision (alive, deadline, program flow) with safe-state handling.
• Develop Complex Device Drivers (CDD) for engine sensing and actuation — crank/cam position, engine speed and direction, spark and injector control, knock windows, misfire detection, MAP sensing.
• Implement timing-critical logic using GTM (TIM, TOM, ATOM, DPLL/angle clock).
• Perform ECU board bring-up — clock/PLL setup, startup code, linker and memory map, peripheral init, and first power-on debug.
• Own issue triaging — reproduce and isolate defects, classify severity/priority, perform root cause analysis on traps, unexpected resets, stack overflows and timing overruns; drive fixes to closure in the defect tracking tool (JIRA/ALM/ClearQuest) with clear analysis reports.
• Debug and validate using Lauterbach Trace32 and ETAS INCA; support calibration, system, hardware and safety teams during integration.

• Infineon AURIX TC3xx (TC38x) experience — startup, memory map, interrupt architecture.
• Knowledge of MCU safety concepts — SMU, MPU, watchdogs, multi-core OS.
• ECM/PCM gasoline engine control software experience with cam/crank sensing and spark/injector actuation.
• Proficiency in Trace32 and INCA; structured defect triaging and RCA discipline.

Preferred Skills

• GTM timing expertise and DSP concepts used in knock detection.
• EB Tresos MCAL configuration; ECU board bring-up on new hardware samples.
• ISO 26262 (ASIL-B/D) exposure, MISRA-C, static analysis, Git/Jenkins CI.
