Thales: Underwater Systems Engineer – RF & Electronic Design Job Title: RF & Electronic Engineer (Underwater Systems – CAP Group)
Thales helps armed forces customers achieve operational advantage in critical missions through high-tech defence mission systems at land, sea, and air. From sonar and electronic warfare to intelligence, surveillance, and reconnaissance (ISR), our technology ensures global safety, impacting millions daily.
At Thales UK, we innovate across aerospace, defence, security, and space, prioritising your well-being with flexible working options: hybrid roles, part-time, job-sharing, or flexible hours. Join a company committed to skilled career development in a diverse, dynamic environment.
About the Role
Location: Thales Underwater Systems (UWS), [specify if confirmed] Sector: Defence / RF & Electronic Engineering
Thales Underwater Systems leads global innovation in underwater sensing, decision-making, and naval protection. Our work spans four key areas:
- Mine Counter Measures
- Anti-Submarine Warfare
- Services
- Future naval capabilities
As an RF & Electronic Engineer within our Communications, Antennas & Propagation (CAP) group, you’ll electronically engineer critical underwater systems—from antennas and tuners to RF distribution units.
You’ll collaborate with architects, solution engineers, and business teams to deliver secure, compliant, and cost-effective solutions while mentoring junior engineers and advancing the Analogue Design and Simulations & Testing capabilities of our team.
Key Responsibilities
-
Design Development:
- Lead the design and prototyping of RF/electronic components (antennas, tuners, distribution units) as per approved development plans.
- Work in cross-functional teams with systems engineers, solution architects, and procurement teams to optimise designs for performance, cost, and manufacturability.
-
Project Execution:
- Decompose technical requirements, assign tasks, and collaborate across disciplines to meet defence standards.
- Support bid preparation, detailed estimates, and production planning.
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.
