Build Things That Matter
We're a small electronics design consultancy that develops connected products for clients ranging from start-ups to established manufacturers. Because we're small, you'll never be "the USB person" or "the RTOS person". Instead, you'll work across the whole product, from first prototype to production.
One project might involve an ESP32 connected to AWS IoT. The next could be a high-speed CAN FD network, a low-power battery device, or an industrial controller. Variety is one of the reasons we working here.
We're looking for someone who enjoys solving difficult technical problems and wants to take ownership of their work.
What You'll Be Doing
- Designing embedded firmware from scratch
- Bringing up new hardware
- Working closely with the team during schematic and PCB design
- Developing robust production-quality code
- Debugging the inevitable "it only fails on customer hardware" problems
- Supporting products through manufacture and field deployment
- Working directly with customers to understand technical requirements
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.
You'll spend time with oscilloscopes, logic analysers and debuggers just as often as you'll be writing code.
Technologies We Regularly Use
No one is expected to know everything on this list.
Typical projects involve:
- C (lots of it)
- Some modern C++
- STM32
- ESP32 (ESP-IDF & ESP-ADF)
- FreeRTOS
- USB
- Ethernet
- Wi-Fi
- Bluetooth
- AWS IoT
- CAN / CAN FD
- SPI, I²C and UART
We'd Like You To Have
- Around 3 to 8 years' experience developing embedded firmware
- Strong C programming skills
- Experience developing on ARM microcontrollers
- Confidence debugging embedded systems
- Experience using oscilloscopes and logic analysers
- The ability to read electronic schematics
- Good communication skills and the confidence to discuss technical ideas with customers
Bonus points if you've worked with:
- ESP32
- STM32
- FreeRTOS
- Wireless / RF products and systems
- Cloud-connected devices
- Embedded Linux
- Basic PCB design or hardware development
