The Opportunity
To support our continued growth and expanding product roadmap, we're seeking a hands-on Embedded Software / Hardware Engineer to join our team. This is a full-time position located in Edinburgh North.
You'll take ownership across the full product lifecycle — from fast-paced prototyping and proof-of-concept development, through to design for manufacture, compliance, and scaling into volume production.
This role suits someone who:
* Enjoys working in a dynamic product development environment
* Is technically curious and thrives on solving complex problems across both software and hardware
* Is practical and resourceful, willing to roll up their sleeves in the lab
* Thinks in a structured way, focusing on reliability, maintainability, and high design quality
* Works independently but can collaborate effectively across disciplines when needed
-----------------------------------
What you will do
* Design, develop, and maintain embedded software for ARM Cortex-M, STM32, and ESP32-based systems
* Design hardware platforms using STM32, ESP32, and related microcontrollers
* Architect robust firmware using C/C++, FreeRTOS, and ESP-IDF frameworks
* Implement secure and efficient IoT connectivity solutions including BLE, WiFi, and OTA updates
* Develop embedded GUI applications using low-level graphics libraries
* Own the schematic and PCB layout process, including component library management
* Validate and debug hardware designs through lab testing, including board rework
* Participate in CI/CD pipelines to streamline embedded development workflows
* Support design for manufacture (DFM) and manage transition of prototypes into volume production
-----------------------------------
Ideal Experience
Embedded Software
* Proficient in C/C++ for embedded systems
* Strong experience with STM32, ARM Cortex-M, and ESP32 (using ESP-IDF)
* Solid understanding of FreeRTOS and real-time embedded software architecture
* Familiar with CI/CD pipelines (e.g., GitLab CI, Jenkins)
* Experience with BLE, WiFi, OTA, and other IoT connectivity protocols
* Familiarity with embedded GUI/graphics libraries
Embedded Hardware
* Skilled in KiCad (or similar) for schematic capture and PCB layout
* Strong grasp of library management best practices
* Experience in EMC/EMI and ESD design and compliance testing
* Knowledgeable in analog and mixed-signal circuits including ADCs and power conditioning
* Experience in RF design (antennas, matching networks, etc.)
* Comfortable with lab validation: oscilloscopes, soldering, board rework
* Understanding of DFM and production processes
-----------------------------------
Bonus Skills
* Knowledge of Python or scripting
* Previous work in automotive electronics and understanding of relevant standards
* Experience designing for safety-critical and functional safety systems
