IR35 Status: Outside IR35
Location: Greater London (3-4 days on site per week min)
Contract Length: 3–6 months, with potential extension

We’re working with an innovative technology business at the forefront of advanced sensing solutions, seeking a Senior Electronics / Firmware Engineer to support the development of next-generation products. This is an opportunity to join a highly collaborative, multidisciplinary team delivering cutting-edge solutions with real-world impact.

In this role, you’ll take ownership of sensor characterisation and optimisation, with a particular focus on humidity and temperature sensing technologies. You’ll play a key part in refining performance, reliability, and integration within sophisticated systems, contributing directly to product development from concept through to validation.

This is a hands-on engineering role suited to someone who enjoys solving complex technical challenges and working closely with hardware, software, and mechanical engineers in a fast-paced R&D environment.

Key Responsibilities

Characterise, test, and optimise sensor performance, particularly metal oxide and electrochemical sensors
Design, develop, and iterate electronic circuits and PCB layouts
Support firmware development for hardware interfacing and system integration
Collaborate cross-functionally to ensure seamless integration across electronics, firmware, and mechanical components
Contribute to prototyping, validation, and performance tuning of advanced sensing systems

Core Skills & Experience

Strong background in electronic engineering, including PCB design and development
Experience working with electrochemical or metal oxide sensors
Solid embedded firmware capability (not necessarily specialist level), including:
- Hardware interfacing
- Communication protocols (e.g. LoRaWAN or similar)
Proven experience taking products from development through to testing or deployment

Highly Desirable

Experience working with volatile organic compounds (VOCs)
Knowledge of air sampling systems or environmental sensing
Background in healthcare, life sciences, or medical device development

Why Apply?

Work on cutting-edge sensing technologies with meaningful real-world applications
Join a highly skilled, multidisciplinary team in a collaborative environment
Opportunity to make a tangible impact on product performance and innovation
Flexible working arrangements and a strong likelihood of contract extension
