The company
CleanTech Talent are partnered with one of the fastest-growing engineering businesses, building mission-critical systems with a production facility onsite in Bristol, they're 100% in house with ownership and manufacturing. This is a hands on engineer's dream place to work.
If you want your RF work to end up in the field rather than in a report, this is that role.
As they continue to scale their processes, team and product pipeline to match the need, it's an ideal time to join.
This is a rare chance to get in early and build something: you'll help shape and lead the RF PCB design and layout function as it grows, with genuine ownership and technical influence rather than a seat in a large, established team.
The role
This is a highly senior individual-contributor role with real technical leadership.
You'll lead RF hardware development on projects — from RF system design and schematic capture through to RF PCB layout — working alongside the RF lead across separate initiatives and helping shape engineering process as the team scales.
You'll join a small, high-calibre team, so you'll need to add value quickly and lead from the front.
It's a genuinely hands-on principal role: concept and architecture through to schematic, layout, bench and field.
Responsibilities
- Lead RF hardware development on projects: RF system design and schematic capture through to RF PCB layout.
- Integrate packaged / surface-mount RF components onto multi-layer boards (this is integration-focused, not bespoke filter or amplifier design from scratch).
- Make circuit-design and PCB-layout decisions driven by the implications of frequency, across RF systems typically spanning ~30 MHz to 6 GHz.
- Own RF PCB design and layout.
- Contribute to SDR-based product development, including the client's in-house SDR.
- Provide technical leadership on hardware projects and help shape processes and procedures as the team grows.
- Work across the design–test–iterate cycle, feeding real-world performance findings back into design.
Reasons to use Rodeo
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.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Essential Attributes
- Solid RF hardware engineering experience across schematic design and, ideally, RF PCB layout.
- A solid understanding of how frequency drives circuit-design and PCB-layout decisions - exact experience across 30 MHz–6 GHz isn't required, but you must grasp the implications.
- Experience integrating packaged / SMD RF components onto multi-layer boards.
- Solid RF fundamentals, valued above any specific tool - KiCad is the priority, Altium is transferable and welcome.
- Senior enough to add value fast with limited hand-holding (this small team needs a contributor, not a project).
- Technical leadership capability — leading hardware development and helping shape process as the function grows.
- A solid RF generalist background (defence, EW or comms domain experience is a nice-to-have, not a requirement).
- Excellent communication — able to clearly explain your technical thinking in live, whiteboard-based technical discussion.
Desirable attributes
- Software-defined radio (SDR) experience — much of the product range is built around SDR.
- High-speed digital design alongside RF.
- Exposure to defence, electronic warfare or communications systems.
- Experience helping shape hardware processes in a fast-scaling engineering team.

What's on offer
- A salary of up to £95,000, dependent on experience.
- A genuine leadership seat: shape and lead the RF PCB design and layout function as it grows.
- Technical lead role on upcoming product initiatives, with real ownership and influence.
- Hands-on RF and SDR product work, including an in-house-developed SDR.
- The energy of one of the region's fastest-growing engineering businesses, at the point where you can still shape how it builds.

- Comprehensive tech package provided
- On-site gym plus monthly yoga sessions
- Daily lunches and snacks in the office
- Flexible working arrangements
- Quarterly Socials
Bristol-based. On-site presence ~3 days per week is important given the hands-on hardware and test work; some flexibility can be discussed for the right person. Relocation support may also be open for discussion.
