You will be responsible for building robust, maintainable codebases that underpin our cutting-edge hardware platforms, ensuring reliable performance in diverse, often mission-critical environments.
What You’ll Do:
Hardware Bring-up & Integration
- Support hardware bring-up activities, including low-level board and SoC development, BIOS development, and interfacing with new hardware components.
- Collaborate with hardware and electrical teams to design and validate system-level functionality, ensuring firmware-hardware interoperability.
- Ensure designs account for resource constraints (memory, power, performance) while adhering to compliance and certification requirements.
Firmware Design & Development
- Architect and implement embedded firmware for new system features, focusing on performance, scalability, and robustness.
- Write, enhance, and debug real-time firmware, ensuring tight integration with underlying hardware.
- Lead firmware architecture design and code reviews, ensuring scalability, modularity, and maintainability.
- Collaborate closely with hardware, systems, and product teams to define requirements and integration strategies.
- Participate in API development, firmware reviews, and documentation to promote best practices in coding and architectural decisions.
Safety-Critical Firmware Development
- Familiarity with key aviation, military, and other U.S. government/industry safety-critical development standards, including DO-178C, DO-254, MIL-STD-2167A, MIL-STD-882, as well as applicable standards from the Department of Defense (DoD), Department of Transportation (DOT), Department of Energy (DOE), and NASA.
- Hands-on development using RTOS platforms such as SafeRTOS, VxWorks, PikeOS, or similar safety-certified real-time operating systems.
About You
- Holds a Master’s degree in Electrical Engineering, Computer Engineering, or a related field.
- 8+ years of experience in embedded firmware development, with a track record of bringing hardware prototypes to production-ready systems.
- Strong skills with low-level debugging, board bring-up, BIOS support, and embedded microprocessor toolchains.
- Ability to architect and document embedded systems, including firmware design specifications, hardware interfaces (SPI, I2C, UART, etc.), and performance trade-offs.
- Experience with test automation, CI/CD pipelines, and collaborative development tools.
Job Requirements
- U.S. Citizenship is required due to USG contract requirements.
- Must be able to obtain and hold a U.S. Secret security clearance.
- You’re willing and able to work from our Palo Alto location at least 1 day per week.
- Proficient in high- and low-level programming (e.g. Python, Julia, C, C++, Rust, MatLab, etc.).
- Proficient in software development methodologies and best practices (e.g., Agile practices, CI/CD, test-driven development.)
- Hands-on experience with real-time systems, embedded microprocessor tools, and advanced debugging techniques.
Nice to Haves:
- Background in aerospace, automotive or other safety-critical industries.
- Familiarity with Guidance, Navigation, and Control (GNC) concepts and sensor fusion algorithms.
- Experience with FPGA development and High-Level Synthesis (HLS) for hardware acceleration, safety-critical control systems, and real-time signal processing.
The US base salary range for this full-time position is expected to be $183k-256k per year. Our salary ranges are determined by role and level. Within the range, individual pay is determined by factors including job-related skills, experience, and relevant education or training. This role may be eligible for annual discretionary bonuses and equity.
