Senior Embedded Firmware Engineer – Bare Metal (Hybrid)

MissionHires is looking for a Senior Embedded Firmware Engineer on behalf of a fast-growing technology company building a high-precision positioning platform for real-time human-machine interaction. In this role, you will own and evolve low-level, bare-metal firmware for next-generation embedded platforms used in medical devices, robotics, and Physical AI applications. This is an opportunity to solve challenging hardware-near engineering problems, influence firmware architecture and standards, and make a direct impact on shipped products in a collaborative, high-growth environment.

• Own the low-level firmware architecture for next-generation embedded platforms.
• Develop highly optimized bare-metal firmware in Embedded C for ARM-based microcontrollers.
• Build firmware that interfaces directly with custom hardware and supports ultra-low-latency, deterministic system behavior.
• Configure and integrate hardware peripherals and interfaces including SPI, I²C, UART, GPIO, timers, interrupts, DMA, ADCs, and other communication peripherals.
• Partner closely with electrical engineers during board bring-up, hardware validation, debugging, and prototype development.
• Diagnose and resolve complex hardware/software integration issues.
• Optimize firmware for performance, memory utilization, reliability, and resource-constrained operation.
• Help define scalable firmware architecture, coding standards, engineering practices, and technical documentation.
• Collaborate across electrical, mechanical, software, product, and other engineering teams throughout the product lifecycle.
• Contribute technical leadership and, where applicable, mentor junior firmware engineers.

• Senior-level embedded firmware development experience.
• Strong Embedded C programming skills; C++ experience is beneficial.
• Extensive experience developing firmware for ARM microcontrollers.
• Strong bare-metal, no-OS firmware development experience.
• Deep understanding of microcontroller architecture, hardware peripherals, interrupts, DMA, and low-level system behavior.
• Experience configuring SPI, I²C, UART, GPIO, timers, ADCs, interrupts, DMA, and communication peripherals.
• Experience developing optimized, resource-constrained embedded systems.
• Strong hardware/software debugging and root-cause analysis skills.
• Ability to work directly with electrical engineers during board bring-up and validation.
• Experience optimizing firmware for performance, memory usage, and deterministic behavior.
• Ability to work independently and take significant technical ownership.
• Strong problem-solving skills for complex embedded systems.
• Bachelor's degree in Computer Engineering, Electrical Engineering, Computer Science, or a related discipline is preferred.
• RTOS experience is desired.
• Embedded Linux exposure is desired.
• Experience with hardware abstraction layers, scalable firmware architecture, and embedded CI/CD practices is desired.
• Experience with Git and internal engineering tool development is desired.
• Knowledge of USB, CAN, Ethernet, BLE, or related communication protocols is desired.
• Experience in medical devices, robotics, industrial automation, or Physical AI is desired.
• Experience in a startup or fast-paced product development environment is desired.
• Experience collaborating with firmware, hardware, cloud, and application software teams is desired.
• Strong technical documentation and mentoring skills are desired.

• Competitive annual salary of $120,000 to $160,000.
• Full-time, direct-hire opportunity.
• Hybrid work arrangement.
• Meaningful technical ownership and direct influence on product architecture, coding standards, and future product direction.
• Opportunity to work on proprietary technology with real-world applications in medical devices, robotics, and Physical AI.
• Collaborative engineering culture with minimal bureaucracy and rapid decision-making.
• Professional growth opportunities within a growing engineering organization planning to expand its team.
• Minimal travel requirements.
