Hardware Architect
Electronics / Systems Architect
Outside IR35 • Excellent Day Rate (£60–£80 ph +) • Majority Remote • 6-Month Contract
Looking for your next contract where you’ll own the entire system—not just one part of it?
We’re working with an innovative technology company developing market-leading wireless products, seeking an experienced Electronics / Systems Architect to join their small, specialised engineering team.
About the Role
This is not a role for someone staying within a single discipline. It’s for an engineer who loves understanding how a product comes together—from electronics, digital systems, RF, testing, integration, and right through to the end customer application.
You'll be working across:
- System architecture
- Hardware integration
- PCB design (Altium experience is desirable)
- Lab testing and debugging
- Measurement & validation
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.
The goal? Solving real-world engineering challenges, guiding products from concept to delivery.
Responsibilities
- Shape system architecture and end-to-end solutions for complex wireless products.
- Lead hardware integration of digital, analog, and RF components.
- Design and debug high-density multi-layer PCBs with complex interconnections.
- Develop test automation scripts (preferably in Python or similar).
- Conduct practical lab-based testing, debugging, and system validation.
- Work hands-on with Software Defined Radio (SDR) or adaptive wireless systems.
- Collaborate closely in a small, highly technical team, owning full system responsibility.
A Bluetooth product background would be a distinct advantage—though not mandatory.
Requirements
- Broad electronics & systems engineering experience
- Strong RF knowledge—able to apply it within a complete system context
- Proven experience in hardware, digital, and communications integration
- Hands-on PCB design & debugging (preferably with Altium)
- Test automation scripting (Python/objective similar supported)
- Approach rooted in lab work—prefers real-world validation over simulation
- Experience with SDR/WiFi/Bluetooth systems (advantageous)
- Thrives in multi-discipline ownership—comfortable seeing the bigger picture
- Ability to debug complex issues and lead design improvements
