Senior Embedded Software Engineer (RTOS)

TL;DR

Senior Embedded Software Engineer (RTOS): Developing foundational platform software for automated driving technologies with an accent on RTOS configurations, memory protection, and hardware abstraction layers. Focus on architecting safety-critical (ASIL) systems, optimizing low-level bus traffic, and ensuring "Freedom from Interference" on ARM-based SoCs.

Location: Must be legally authorized to work in the United States on a permanent basis. Offices in Pittsburgh, PA, Palo Alto, CA, and Detroit, MI.

Salary: $179,200 - $268,800 USD

Company

hirify.global develops automated driving technologies, including L3, as a subsidiary of Ford Motor Company.

What you will do

• Drive the design and implementation of centralized RTOS configurations, including DDR memory maps, UDMA channels, and peripheral assignments.
• Architect MPU and hardware firewalls to ensure "Freedom from Interference" (FFI) between safety-critical (ASIL) and non-safety (QM) tasks.
• Lead the setup and evolution of the Hardware Abstraction Layer (HAL) and low-level drivers across different projects and platforms.
• Manage core SoC integration modules, ensuring they are architected for long-term maintainability and testability.
• Profile and optimize low-level bus traffic and memory access patterns (DDR, DMA) to minimize latency for real-time control loops.
• Serve as the SME for hardware-software interfaces and perform deep-dive code reviews to ensure architectural consistency.

Requirements

• Bachelor's degree in Computer Engineering, CS, Electrical Engineering, Robotics or related (4+ years exp), or Master's (2+ years), or PhD.
• Expertise in embedded C/C++ and ARM-based SoC architectures, including memory-mapped I/O and DMA controllers.
• Direct experience configuring MPUs and hardware-level firewalls to enforce spatial and temporal isolation.
• Proven ability to build or significantly refactor Hardware Abstraction Layers (HAL) to support multiple hardware targets.
• Expert-level use of JTAG, Tracealyzer, and logic analyzers to verify hardware-software interactions.
• Must be legally authorized to work in the United States on a permanent basis.

Nice to have

• Experience with ISO 26262 safety-critical development and FFI requirements for ASIL systems.
• Familiarity with Automotive Ethernet, UDS, or SOME/IP.
• Expertise in Linux-based software development, including gtests, Python, Bazel, and Docker.

Culture & Benefits

• Comprehensive medical, dental, and vision insurance with HSA employer match.
• Employer-matched 401(k) retirement plan with immediate vesting.
• Unlimited vacation and 15 paid holidays.
• Paid parental and medical leave.
• Daily lunches, snacks, and beverages available in all office locations.
• Wellness stipend and professional development reimbursement.
