Job summary

SubSea Craft is seeking an Electrical Design Engineer to develop, integrate, and prototype electrical and electronic systems for our special-purpose platforms. You will join our fast-paced engineering team, driving from concept through design, prototyping, testing and validation while applying hands-on workshop skills.

The role blends electrical design with systems engineering, focusing on power distribution, wiring harnesses, component selection, sensor integration, and assembly of prototype

Qualifications

• Bachelor's or master's degree in Electrical/Electronics or Mechatronic Engineering, Aerospace Engineering, Robotics or other relevant STEM discipline.
• Practical experience designing, building, integrating, or testing electrical/electronic systems.
• Understanding of electrical engineering fundamentals including DC power systems, circuit protection, grounding, signal integrity, cable sizing, connectors, and electrical interfaces.
• Hands‑on ability with electrical assembly and test equipment, such as multimeters, oscilloscopes, bench power supplies, soldering equipment, and crimping tools.
• Experience producing and interpreting electrical schematics, wiring diagrams, and technical documentation.

Responsibilities

• Assist in the ongoing development of electrical and electronic systems for special-purpose engineering platforms, including Unmanned Aerial Systems (UAS).
• Produce electrical designs including system architecture, schematics, wiring diagrams, cable/harness designs, connector specifications, and power distribution systems.
• Perform electrical calculations and engineering assessments, including power budgets, voltage drop, current loading, cable sizing, protection requirements, and component derating.
• Assist with the integration of sensors, flight controllers, communications systems, telemetry equipment, and other electronic subsystems.
• Produce and maintain appropriate engineering documentation, including BOMs, drawings, interface definitions, test procedures, build documentation, and design records.
• Support off-site system and flight trials at external test locations, including troubleshooting and modification of prototype systems.
• Work with suppliers and external partners on component selection, procurement, technical queries, obsolescence, and regulatory/compliance requirements.
• Support electrical testing and validation activities, including bench testing, test-rig activities, continuity and insulation checks, functional testing, system commissioning, and fault diagnosis.
• Support configuration and commissioning of embedded and control hardware and, where required, interface with associated software.
• Undertake a combination of office‑based engineering design and hands‑on workshop activities, including wiring, soldering, crimping, cable assembly, electrical installation, fault finding, and prototype modification.
• Support the selection and integration of electrical and electronic components, including power supplies, batteries, sensors, actuators, motors, controllers, communications equipment, and embedded hardware.
• Undertake rapid prototyping of electrical systems and subsystems, progressing designs from initial concepts through to fully functioning prototypes.
