Electronics Engineer
£55,000 – £70,000 + Benefits
Cambridge – 3 days onsite per week
Start date – ASAP
Zenovo are recruiting for an Electronics Engineer to join an IoT company in Cambridge. This role sits at the intersection of electronic design, hardware engineering, and certification, with a strong focus on ensuring battery-powered products are engineered for use in hazardous environments.
You will act as the technical authority for electronics design decisions that impact compliance approvals (ATEX, IECEx, NRTL, radio, and EMC), working closely with a variety of electronics, firmware and software engineers throughout the full product lifecycle.
Role Overview
As an Electronics Engineer, you will be responsible for designing, reviewing, and validating electronic hardware to meet hazardous-area and radio requirements.
Rather than purely managing compliance, you will help shape circuit architecture, component selection, PCB layout, and system-level design to enable certification and safe deployment in industrial environments.
You will collaborate with Engineering and Operations teams to translate standards into practical design solutions and ensure products are robust, manufacturable, and certifiable for global markets.
Key Responsibilities
Electronics & Hardware Engineering
Act as the electronics engineer for IoT products used in hazardous environments.
Review and influence schematics, PCB layouts, and component selection to meet intrinsic safety and EMC requirements
Support design trade-offs related to power, thermal, RF, and protection strategies
Ensure electronics designs align with IEC/EN/UL 60079-0 and 60079-11 from concept through production
Certification & Engineering Validation
Assist with ATEX, IECEx, NRTL, and radio certifications from an engineering perspective
Work with test houses and notified bodies to define test strategies and resolve technical issues
Support change control, design updates, and follow-up inspections
Radio & EMC Engineering
Provide technical leadership for radio and EMC compliance (ETSI, FCC, regional approvals)
Coordinate test planning, pre-compliance activities, and design fixes
Support antenna, layout, and RF-related design decisions
Technical Documentation & Design Records
Own and maintain hardware design files, technical justifications, and supporting documentation
Contribute to safety and user documentation with strong technical input
Maintain structured product technical files
Global Product Support
Support expansion into new markets (e.g. Brazil, Canada, Asia) by adapting designs to regional technical requirements
Act as a point of escalation for electronics-related compliance and audit queries
Skills & Experience
Degree in Electronics or Electrical Engineering (or related discipline)
3+ years' experience working on electronic hardware design for regulated products
Strong ability to read, review, and challenge schematics and PCB layouts
Experience working with EMC, RF, and radio standards (FCC, ETSI)
Nice to have - Experience designing or supporting products for ATEX / IECEx / hazardous environments
