Our systems listen, so others can be forearmed.
We are hiring Head of Machine Learning as we embark on the next critical phase of our Acoustic Detection product roadmap.
Arcani takes its name from the Arcani of Roman Britain - elite scouts known for their agility, intel and mobility. Today, we’re building the modern equivalent - sensor scouts designed to detect and protect, giving defenders the edge.
The Role
The Electrical Engineer will be responsible for the design, development, integration and testing of electrical and electronic systems used within ARCANI’s products.
Working closely with our acoustics, machine learning, software and mechanical engineering teams, you will help transform prototypes into reliable, manufacturable and field-ready systems.
The role will cover power systems, electrical architecture, component selection, wiring, PCB development, sensor integration, communications hardware and environmental testing.
Key Responsibilities
- Design and develop electrical architectures for ruggedised, deployable sensing systems.
- Develop power distribution, battery management, protection and voltage regulation solutions.
- Design, review and test printed circuit boards and associated electronic assemblies.
- Select suitable components, connectors, cables and electrical interfaces for defence and outdoor environments.
- Integrate microphones, processors, radios, batteries, antennas and other sensors into complete systems.
- Produce electrical schematics, wiring diagrams, cable schedules, bills of materials and technical documentation.
- Develop wiring looms and support the design of repeatable production and assembly processes.
- Evaluate power consumption and optimise systems for extended battery-operated deployment.
- Support the integration of NVIDIA Jetson platforms, microcontrollers and embedded computing hardware.
- Diagnose electrical faults during prototype development, environmental testing and field trials.
- Conduct bench testing, verification, validation and design reviews.
- Support electromagnetic compatibility and electromagnetic interference testing and mitigation.
- Design systems with appropriate protection against reverse polarity, overcurrent, overvoltage, electrostatic discharge and environmental conditions.
- Work with mechanical engineers to ensure appropriate packaging, cooling, ingress protection and connector placement.
- Work with software and machine learning engineers to define hardware interfaces and system requirements.
- Support suppliers and manufacturing partners during component sourcing, assembly and production.
- Identify component obsolescence, supply-chain risks and appropriate alternative components.
- Support product certification, compliance and technical assurance activities.
- Attend field trials and demonstrations to support system deployment, troubleshooting and performance evaluation.
- Contribute to engineering planning, risk management and continuous product improvement.
