Embedded Hardware Engineer

About Us

Amidon Heavy Industries is a startup building unmanned systems for the offshore industry. We develop uncrewed surface vessels (USVs) that autonomously deploy tethered remotely operated vehicles (ROVs) to inspect subsea pipelines, telecom cables, and offshore infrastructure. Our goal is to deliver reliable subsea awareness at a fraction of the cost of traditional crewed vessels.

The Role
We are hiring an Embedded Hardware Engineer focused on PCB design and testing to develop the electronics that power and control our marine vessels. You will take an evolving prototype platform and help drive it toward a production-ready system by designing, bringing up, and validating PCBs for propulsion, power management, sensing, networking, and autonomy. The work spans architecture, schematic capture, layout, Ethernet- and STM32-based embedded design, wireless communication modules, and rigorous bench and field testing, in close coordination with mechanical and software teams.

This is a hands-on role that combines design, debug, and iteration. You will help define how our boards are built, how they are tested, and how they perform in the field.

Responsibilities:

• Architect, design, and maintain PCB-level electronics for propulsion, power distribution, energy storage, control, and communications

• Own schematic capture and PCB layout using modern EDA tools, from concept through fab and assembly

• Design STM32-based control boards, including power, clocking, reset, debug (SWD/JTAG), and peripheral interfaces (SPI, I²C, UART, CAN, etc.)

• Design and integrate Ethernet interfaces (MAC/PHY, magnetics, connectors) and on-board networking topologies to support vessel-wide communication

• Integrate wireless communication modules (e.g., Wi-Fi/BLE, cellular, or other RF) including power, digital interfaces, and antenna connections

• Bring up new boards: develop test plans, execute bench testing, and debug hardware issues with oscilloscopes, logic analyzers, and protocol analyzers (Ethernet, serial buses)

• Support EMC, environmental, and reliability testing; iterate designs to address failures and improve robustness

• Collaborate with firmware and software teams to define interfaces, support STM32 and networking bring-up, and validate end-to-end functionality (wired and wireless)

• Maintain documentation: schematics, layout files, BOMs, test procedures, and revision history

Qualifications:

• Degree in Electrical Engineering or related field

• 2–5 years of experience in PCB design and testing for robotics, vehicles, aerospace, marine, or similar embedded systems

• Proficiency with PCB CAD tools for schematic capture and layout (e.g., Altium, KiCad, or similar)

• Hands-on experience designing STM32- or similar ARM-based embedded systems at the board level

• Experience with Ethernet hardware design: PHY selection, magnetics, differential pair routing, and signal integrity considerations

• Experience integrating wireless communication modules (e.g., Wi-Fi/BLE, cellular) including layout around RF modules and antenna interfaces

• Strong understanding of power electronics, mixed-signal design, grounding, noise mitigation, and ESD/EMI best practices

• Hands-on experience with board bring-up, debugging, and failure analysis using standard lab equipment

• Demonstrated ability to take PCB designs from prototype through to stable, manufacturable revisions

• Familiarity with environmental, safety, and reliability considerations for harsh or marine environments

Bonus Points:

• Experience designing electronics for uncrewed or remotely operated marine vehicles

• Background in high-reliability or mission-critical embedded hardware

• Experience with battery management systems, high-current power stages, or hybrid power systems

• Experience with high-speed digital design (e.g., Ethernet, USB) and EMI/EMC mitigation and compliance testing

• Experience developing automated or semi-automated test setups (e.g., Python-based scripts, hardware-in-the-loop)

• Experience with RF layout practices, antenna placement, and working with RF test equipment
