RC Fornax is looking for Hardware Engineer to join a team developing advanced underwater sensing and acoustic technologies.
This is an excellent opportunity for an experienced hardware engineer to contribute to the development of innovative sonar and maritime systems used in challenging and mission-critical environments. The successful candidate will be involved throughout the engineering lifecycle, from requirements definition and system architecture through to integration, testing and verification.
Key Responsibilities
- Develop and formalise hardware specifications for sonar and underwater acoustic systems.
- Define hardware requirements, interfaces, functionality and performance characteristics for sonar subsystems and associated equipment.
- Support system architecture activities through modelling, simulation, prototyping and trade studies.
- Design, develop and integrate electronic hardware for advanced sonar and maritime sensing applications.
- Develop circuitry associated with acoustic transducers, hydrophones, transmitters, receivers and data acquisition systems.
- Contribute to the design of beam-forming, signal acquisition, amplification, filtering and signal-conditioning hardware.
- Produce verification plans, test procedures and acceptance criteria for hardware subsystems.
- Conduct integration, fault-finding, troubleshooting and root-cause analysis activities on complex electronic systems.
- Analyse test and operational data to identify opportunities for performance improvement and optimisation.
- Support hardware qualification, verification and validation activities throughout the development lifecycle.
- Collaborate with multidisciplinary teams including systems, software and mechanical engineers to deliver integrated solutions.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
