Low level firmware engineer
Embedded Software Developer
Location: Hybrid remote in London SE1, with 2 days per week on-site near London Bridge Job Type: Full-time, Permanent Company: Bermondsey Electronics
About the Role
Bermondsey Electronics, a contract electronics development company, is seeking an embedded software developer to expand its team. This role offers exciting challenges to develop and debug drivers, platforms, and low-level code across varied systems and hardware.
Ideal for motivated graduates or early-career engineers with a strong foundation in embedded C and a hands-on approach. Experience is beneficial, but opportunities for rapid skill development are available, provided candidates are comfortable with hands-on learning and flexibility across projects.
Key Responsibilities
-
Board Bring-Up & Driver Development
- Test and verify printed circuit boards (PCBs) supplied by clients.
- Debug, modify, or write peripheral drivers (e.g., SPI, DAC, LVDS) to ensure boards function correctly.
- Configure and test embedded OS environments, from bare-metal through Linux and Android.
- Resolve schematic, placement, or signal integrity issues using tools like oscilloscopes, logic analysers, and bench power supplies.
-
Project Variety
- Work across platforms including STM32, DA1453x, NXP i.MX RT/RW6xx, i.MX 8M, and interface with diverse environments (e.g., FreeRTOS, Zephyr, Android, Yocto).
- Support cross-team workflows by developing drivers that form the bridge to application-level software written by specialists.
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.

- Unrestricted right to work in the UK (no current or future need for visa sponsorship).
Advantageous Qualities
- Software Comfort
- Hands-on experience with:
- Embedded OS (FreeRTOS, Zephyr, ThreadX, Android architecture).
- Optimisation (e.g., power management, latency reduction).
- Allowable to know builds: CI/CD for embedded initialization.
- Hands-on experience with:
