Socket.dev; Bristol (RI); On-site; USD 110,000 - 150,000; Full time

Job summary

Vatn Systems in Bristol, RI is seeking an Embedded Firmware Engineer to design and maintain firmware for autonomous underwater vehicles. You will work from bare-metal to embedded Linux, using C, C++, and Go to build reliable software that runs at the edge in harsh maritime conditions.

You will bring up hardware, write drivers, optimize performance and power, and collaborate with hardware, robotics, and autonomy teams.

Qualifications

• Degree in Electrical Engineering, Computer Engineering, Computer Science, or related field (or equivalent practical experience).
• 3–5 years of professional embedded software/firmware development experience.
• Strong proficiency in C and C++ for embedded microcontrollers (bare-metal and/or RTOS).
• Hands-on experience developing firmware for STM32 microcontrollers (e.g., STM32CubeMX/HAL, LL drivers, or bare-metal).
• Experience developing on embedded Linux platforms.
• Solid understanding of hardware/software integration and debugging with oscilloscopes, logic analyzers, and JTAG/SWD.
• Experience with embedded communication protocols (UART, SPI, I2C, CAN, Ethernet).
• Familiarity with real-time constraints, interrupts, DMA, and memory management.
• Experience writing firmware for power-constrained systems.
• Proficiency with Git.
• Excellent problem-solving and teamwork.
• United States Citizen or Permanent Resident (security clearance).
• Familiarity with cross-compilation/build systems is a plus.

Responsibilities

• Design, build, and maintain firmware for embedded microcontrollers (bare-metal and RTOS).
• Develop system-level software and services on embedded Linux boards using Go, C, and C++.
• Bring up new hardware: board bring-up, bootloaders, drivers, and BSPs.
• Implement and debug communication between subsystems over UART, SPI, I2C, CAN, Ethernet.
• Integrate sensors, actuators, and peripherals; implement real-time control and telemetry paths.
• Optimize firmware for performance, memory footprint, and power.
• Collaborate with electrical, mechanical, and autonomy engineers to meet system requirements.
• Write and maintain unit and integration tests; support hardware-in-the-loop testing.
• Participate in code reviews and improve engineering practices.
• Troubleshoot, debug, and upgrade existing firmware, including on-vehicle and field debugging.

Job description

Embedded Firmware Engineer

Embedded Firmware Engineer (Mid-Level)

Company: Vatn Systems
Location: Bristol, RI
Type: Full-time (Onsite)

About Vatn Systems:

Vatn Systems is an innovative startup at the forefront of designing and manufacturing autonomous underwater vehicles (AUVs). Our mission is to revolutionize underwater security, exploration, research, and operations through cutting-edge technology and unparalleled engineering. Our AUVs are defining the next generation of underwater autonomy.

The Role

We are looking for a talented and motivated Embedded Firmware Engineer to join our growing team. In this role, you will design, develop, and maintain the firmware that runs our AUVs — from bare-metal on embedded microcontrollers to system software on embedded Linux boards. You'll write C, C++, and Go across the stack, bring up new hardware, and own the low-level software that keeps our vehicles running reliably in demanding maritime conditions. The ideal candidate is a proactive engineer who enjoys working close to the metal and thrives at the hardware/software boundary.

What You'll Do

• Design, build, and maintain efficient, reliable firmware in C and C++ for embedded microcontrollers (bare-metal and RTOS).
• Develop system-level software and services in Go, C, and C++ on embedded Linux boards.
• Bring up new hardware: board bring-up, bootloaders, device drivers, and board support packages.
• Implement and debug communication between subsystems over interfaces such as UART, SPI, I2C, CAN, and Ethernet.
• Integrate sensors, actuators, and peripherals, and implement real-time control and telemetry paths.
• Optimize firmware for performance, memory footprint, and power.
• Collaborate with electrical, mechanical, and autonomy engineers to translate system requirements into robust embedded solutions.
• Write and maintain unit and integration tests, and support hardware-in-the-loop testing.
• Participate in code reviews, providing and receiving constructive feedback to improve our engineering practices.
• Troubleshoot, debug, and upgrade existing firmware, including on-vehicle and field debugging.

What You'll Need

Required Qualifications:

• Degree in Electrical Engineering, Computer Engineering, Computer Science, or a related technical field (or equivalent practical experience).
• 3-5 years of professional embedded software/firmware development experience.
• Strong proficiency in C and C++ for embedded microcontrollers (bare-metal and/or RTOS).
• Hands-on experience developing firmware for STM32 microcontrollers (e.g., STM32CubeMX/HAL, LL drivers, or bare-metal register-level programming).
• Experience developing on embedded Linux platforms.
• Solid understanding of hardware/software integration: reading schematics and datasheets, and debugging with oscilloscopes, logic analyzers, and JTAG/SWD.
• Experience with embedded communication protocols (e.g., UART, SPI, I2C, CAN, Ethernet).
• Familiarity with real-time constraints, interrupts, DMA, and low-level memory management.
• Experience writing firmware for power-constrained and/or resource-limited systems (battery power budgets, tight memory/timing footprints).
• Proficiency with version control systems, specifically Git.
• Excellent problem-solving skills and the ability to work effectively in a team environment.
• United States Citizen or Permanent Resident.
• Ability to gain a security clearance.

Nice-to-Haves:

• Experience with cross-compilation, build systems (e.g., CMake, Make, Yocto/Buildroot), and toolchains for embedded targets.
• Experience developing with Go.
• Experience with serialization protocols like Protobufs, DDS, etc.
• Familiarity with robotics middleware or modern robotics frameworks (e.g., ROS 2).
• Experience with CI/CD pipelines for embedded software and automated hardware testing.
• Knowledge of containerization and deployment on edge devices.
• Experience with maritime sensors, underwater acoustics, or subsea systems.
• Familiarity with functional safety or safety-critical software development practices.
