We’re looking for a Senior Embedded Engineer to join a growing team in Bristol
This is a client-facing role working directly with major global clients on multiple concurrent projects across diverse sectors. The work is varied, fast-paced, and highly rewarding, offering the opportunity to develop advanced IoT and embedded systems from concept through to production.
You’ll initially take ownership of the embedded function within a key project, then help define the future of the department - shaping its processes, standards, and team as it grows.
It’s an ideal role for someone ready to take a significant step up in responsibility and leadership, with the long-term goal of building and leading the embedded engineering capability within an innovative, forward-looking company.

* Lead development using ESP-IDF, including OTA updates, BLE, Wi-Fi, and peripheral integration.
* Work directly with global clients to define, develop, and deliver high-quality embedded systems.
* Develop and optimise firmware across BLE, Wi-Fi, LoRa, ZigBee, LTE, 5G, and NB-IoT.
* Integrate and control vision systems (thermal and RGB cameras).
* Collaborate closely with electronics engineers on PCB bring-up, debugging, and validation.
Essential Skills & Experience
• Strong C/C++ programming for embedded systems.
• Expert knowledge of ESP32 (ESP-IDF) and STM32 microcontrollers.
• Solid understanding of wireless communication protocols: BLE, Wi-Fi, LoRa, ZigBee, LTE,
5G, NB-IoT.
• Proven experience implementing OTA (Over-The-Air) update systems.
• Ability to read schematics and collaborate effectively with hardware teams.
• Experience using JTAG/SWD, oscilloscopes, and logic analysers.
• Familiarity with RTOS (FreeRTOS or similar) and event-driven architectures.
• Confident communicator, comfortable engaging with clients and presenting solutions.
Benefits
* Hybrid working – 2 days per week from home.
* Flexible hours (flexi-time).
* Work on multiple concurrent, high-impact projects with global industry leaders.
* Ongoing professional development and career progression support.
* A collaborative, engineering-led culture that values innovation, autonomy, and excellence.
* Monthly team socials
