Description:
Embedded Software Engineer
Bristol
£50,000-£55,000
Hybrid
My client is a design and technology consultancy specialising in IoT, embedded systems, and connected devices. They partner with global leaders in defence, medical, industrial, and energy sectors to design and deliver innovative, production-ready technology. Their multidisciplinary team brings together electronics, firmware, software, mechanical design, and manufacturing
expertise under one roof.
Role Overview
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.
This position represents a major career growth opportunity. As my client continues to expand, they are establishing firmware as a distinct and autonomous function within the business.
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.
Key Responsibilities
Design, develop, and maintain embedded firmware in C/C++ for ESP32 and STM32 platforms.
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.
• Experience with vision systems or camera integration (e.g. Lepton, Arducam).
• 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.
Package
• £50,000–£55,000 salary + profit share bonus (eligible after 12 months).
• Hybrid working – 2 days per week from home.
• Flexible hours (flexi-time).
• Work on multiple concurrent, high-impact projects with global industry leaders.
• A genuine opportunity to take ownership, shape a new department, and grow into a leadership role.
• Ongoing professional development and career progression support.
• A collaborative, engineering-led culture that values innovation, autonomy, and excellence
