Job summary

Pentangle Tech Services | P5 Group in Auburn Hills, MI is seeking an Embedded Software Engineer to develop and integrate core embedded software for gasoline ECM/PCM on Infineon AURIX TC3xx, covering AUTOSAR BSW foundation, ECU bring-up, and safety-focused coding.

You will configure multi-core AUTOSAR OS, implement ECU startup/shutdown sequencing, NVM design, and be hands-on with complex device drivers for engine sensing and actuation while triaging issues with tools like Lauterbach Trace32 and

Qualifications

Strong Embedded C with MCU debugging.
Hands-on AUTOSAR BSW integration and CDD development.
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.

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 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.
