Overview

Principal Hardware Engineer | Martine | AUV | Robotics | Harwell – Hybrid | £65,000pa - £70,000pa plus share scheme & benefits. A stealth robotics company in the Oxfordshire area seeks a Principal Hardware Engineer to lead the design, integration, and testing of advanced hardware systems for autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs). Develop mission-critical electronics and system architectures that operate reliably in challenging marine environments.

The role requires passion for robotics in the maritime and autonomous/unmanned vehicle sectors. Applicants must be British or have resided in the UK for a minimum of 5 years due to SC clearance requirements.

Responsibilities

• Lead the architecture and development of hardware systems for underwater unmanned platforms, including power distribution, embedded electronics, sensor integration, and control systems.
• Design and oversee development of custom PCBs, enclosures, and interconnect systems that meet environmental and operational requirements (pressure, corrosion, vibration).
• Evaluate and integrate marine sensors (e.g., sonar, cameras, DVLs, IMUs) and actuators into system designs, ensuring underwater performance and compatibility.
• Develop and implement robust electrical and communication interfaces (e.g., Ethernet, RS-232/485, CAN, I2C, SPI) for high-reliability operation.
• Lead hardware system integration and testing, including pressure testing, EMI/EMC validation, and underwater operational trials.
• Collaborate with software, mechanical, and systems engineers to ensure cohesive design and successful system-level integration.
• Generate and maintain documentation including schematics, BOMs, test plans, design justifications, and regulatory compliance records.
• Support field testing and deployments, including troubleshooting and field-based diagnostics.

Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Mechatronics, or a related field.
• 8+ years of experience in hardware engineering, preferably in unmanned systems, robotics, or rugged embedded systems.
• Proficiency in PCB design and layout tools (e.g., Altium, KiCAD, OrCAD) and electrical simulation/analysis tools.
• Hands-on experience designing for harsh environments—including pressure, saltwater exposure, and thermal constraints.
• Strong understanding of signal integrity, grounding, shielding, and EMI/EMC considerations.
• Familiarity with underwater communication systems (e.g., acoustic modems, fiber optics, RF through water).
• Excellent analytical, problem-solving, and communication skills.
• Demonstrated ability to lead complex hardware development efforts from concept through deployment.

Experience

• Experience with low-power design, battery management systems, and subsea power architectures.
• Knowledge of safety and regulatory standards for marine or defense systems.
• Prior work on AUVs, ROVs, or similar subsea robotics platforms.
