Senior Electrical Engineer

Greywright is hiring a Senior Electrical Engineer to lead the build-out and improvement of electrical design for complex maritime systems. You will drive system-level electrical decisions, from power generation and distribution to isolation and protection, across vessels that integrate many in-house and third-party components.

You will also shape board-level design for new electronics built to survive the marine environment: salt, moisture, shock, vibration, and wide temperature swings.

What you'll do

• Own and evolve the system-level electrical architecture for Greywright's maritime systems, including power generation, storage, distribution, and protection.
• Design power management for marine platforms: battery and energy storage systems, DC and AC distribution, load management, and charging.
• Define electrical isolation, grounding, and bonding strategies to protect components, prevent ground loops and galvanic corrosion, and keep sensitive electronics clean.
• Set electrical interface requirements for in-house and third-party components, and lead integration across vendors.
• Inform and review board-level design for new electronics built for the marine environment, including power supplies, isolation, connectors, conformal coating, and thermal design.
• Lead EMI/EMC design and mitigation so radios, sensors, and control systems coexist on the same platform.
• Own wiring harness and cable architecture, including connector selection, sealing, and routing for wet and high-vibration environments.
• Perform load, fault, and short-circuit analyses, and design for safe failure and graceful degradation.
• Support environmental and qualification testing for shock, vibration, salt fog, and immersion, and drive design changes from the results.
• Troubleshoot electrical issues in the lab and in the field, and mentor other engineers.

What you bring

• B.S. in Electrical or Electronics Engineering, or a related field.
• 8+ years of electrical engineering experience, including system-level electrical design of complex vehicles or platforms.
• Hands-on experience with power management in marine systems, including batteries, power conversion, and distribution.
• Deep understanding of electrical isolation, grounding, and bonding, including isolated power supplies and galvanic isolation of signals.
• Experience guiding or performing board design, from schematic through layout review, for harsh-environment electronics.
• Strong knowledge of designing electronics for the marine environment: corrosion, moisture ingress, sealing, shock, and vibration.
• Experience with EMI/EMC design and testing.
• Proficiency with schematic and PCB tools (e.g., Altium) and with lab equipment for debugging.
• Ability to lead electrical decisions across hardware, software, and outside vendors.
• Willingness to travel up to 50% of the time when needed.
• This role requires access to ITAR/EAR-controlled data; U.S. person status is required as defined by 22 CFR 120.62.

Nice to have

• M.S. in Electrical Engineering or a Professional Engineer (PE) license.
• Familiarity with marine and military electrical standards (e.g., ABYC E-11, IEEE 45, MIL-STD-461, MIL-STD-1399, MIL-STD-810).
• Experience with high-voltage lithium battery systems and battery management systems.
• Experience with hybrid or electric marine propulsion.
• Background designing electronics for uncrewed or autonomous vessels.
• Experience with CAN, Ethernet, and other vehicle networks.
• Experience with environmental qualification testing programs.
• Eligibility to obtain a U.S. Secret or higher security clearance; an active clearance is not required.

• Meaningful early-stage equity.
• Great health, dental, and vision insurance.
• Unlimited vacation.
