Senior Embedded Software Engineer (C++) - Hardware Safety

Meet the team:

The Embedded Software team develops foundational platform software critical to development across the company. The Hardware Safety & Power Systems group specializes in the real-time firmware that orchestrates safe system behavior during fault conditions, power transitions, and thermal events.

We develop FreeRTOS and SafeRTOS-based drivers, state machines, and diagnostic frameworks for power management, thermal monitoring, voltage supervision, and hardware watchdog systems on TDA4 (Jacinto 7) embedded targets. Projects often require deep collaboration with hardware teams (PMIC vendors, SoC architects), safety engineers (ISO 26262 compliance), and system integration teams across the company.

What you’ll do: 

• Own the end-to-end architecture of hardware safety and power management systems: design safe-state strategies, power sequencing across multiple cores and PMICs, thermal throttling, and watchdog orchestration. Your designs must meet ASIL-B/C safety goals
• Implement low-level drivers and firmware for safety-critical integrated circuits (PMIC, voltage supervisor, thermal monitor) directly from datasheets and the TDA4 Functional Safety Manual. These drivers run on bare metal and FreeRTOS; they must be bug-free and testable
• Lead the development of hardware-software safety diagnostic frameworks — integrate TI Safety Diagnostic Library (LBIST, PBIST, ECC, DCC, ESM) into the firmware; ensure diagnostic coverage maps to ISO 26262 hardware fault metrics; mentor engineers on coverage traceability
• Consistently perform deep-dive code reviews across all hardware safety modules. Ensure PRs are simple, bug-free, and adhere to unified architectural vision (clean driver interfaces, consistent error handling, testable design patterns). Root out assumptions that could lead to latent ASIL-rated failures
• Serve as the SME for hardware-firmware-safety interfaces. Navigate ambiguity in hardware requirements (PMIC sequencing, watchdog timing, thermal limits, voltage thresholds). Mediate disagreements in technical approach through evidence-based influence and clear understanding of safety constraints
• Mentor engineers on embedded safety patterns — code review discipline, hardware driver architecture, RTOS integration, ISO 26262 traceability, and functional safety reasoning. Build capability across the team

What you'll need to succeed:

• Bachelor's degree in Computer Engineering, Computer Science, Electrical Engineering, Robotics or a related field and 4+ years of relevant experience (or Master's degree and 2+ years of relevant experience, or PhD)
• Experience in embedded C/C++ with deep understanding of advanced language features, design paradigms, and embedded constraints (no exceptions, no RTTI, careful memory management). Proven ability to design clean abstractions and interface-based code for testability
• Proven expertise in ARM-based SoC architectures, specifically ARM Cortex-R5F: memory-mapped I/O, interrupt controllers (VIM), MPU configuration, cache behavior, and memory barriers. Experience debugging at the register level using datasheets
• Direct experience configuring MPUs and hardware-level firewalls to enforce spatial and temporal isolation in multi-core, safety-critical environments
• Experience building or significantly refactoring Hardware Abstraction Layers (HAL) to support multiple hardware targets, RTOS environments, or variant configurations. Understands the role of HAL in isolating driver complexity and enabling testing
• Ability to root-cause complex system failures — power sequencing hangs, missed watchdog feeds, thermal throttle race conditions, interrupt latency issues — involving shared memory, RTOS task scheduling, and hardware peripherals without supervision
• Ability to see potential pitfalls in low-level designs (e.g., power rail ordering dependencies, watchdog timeout misconfiguration, voltage threshold hysteresis). Can express designs in sufficient detail (state diagrams, timing requirements, register-level sequences) for rapid, correct implementation
• Expert-level use of embedded debugging tools (JTAG, on-target debugging, logic analyzers) to verify low-level hardware-software interactions and timing-critical behavior
• Deep understanding of Real-Time Operating Systems — FreeRTOS and/or SafeRTOS: task lifecycle, inter-task synchronization, interrupt handling, timing constraints, and periodic task patterns. Comfortable reasoning about task preemption, priority inversion, and stack requirements
• Direct experience developing drivers for safety-critical integrated circuits (PMIC, voltage supervisor, thermal sensor, or equivalent) from datasheet: SPI/I2C protocol implementation, register-level configuration, fault handling, and diagnostic integration
• Foundational knowledge of ISO 26262 ASIL-B/C functional safety concepts — safe-state strategies, diagnostic coverage, hardware/software fault tolerance allocation, and traceability. Ability to map code behavior to safety requirements without constant guidance

Nice to have: 

• Direct experience with TDA4 / J784S4 (Jacinto 7) or other TI automotive SoCs — familiarity with TI PSDK, SDL (Safety Diagnostic Library), register maps, and peripheral architecture significantly accelerates ramp-up
• Expertise in Linux-based embedded software development including gtests, Python scripting, Bazel build system, and Docker containerization for embedded CI/CD
• Prior involvement in ISO 26262 functional safety audits or certification — experience with Jama requirements traceability, FMEA/HARA, and safety case argumentation
• Experience with hardware diagnostic frameworks — LBIST (Logic BIST), PBIST (Programmable BIST), ECC integration, or other ISO 26262 diagnostic mechanisms
• Proficiency with advanced embedded debugging tools — Tracealyzer for RTOS visualization, logic analyzers for protocol decoding, or in-circuit emulators
• Prior automotive or safety-critical domain experience — body control, powertrain, medical devices, industrial control, or aerospace/defense
