Electronics Engineer

Edinburgh | Hybrid | Up to £65,000

Ever wondered what stops a manhole exploding under a city street, or a substation being tampered with before anyone notices? That's the world our client operates in. They build real-time monitoring technology that protects critical national infrastructure - electricity, gas, water, transport, and communications networks - detecting and preventing the human and natural interference that leads to costly damage, service disruption, and safety incidents.

It's a small, close-knit engineering team where everyone works as a generalist - dipping into electronics, firmware, mechanical design, data, software, and even machine learning. It's a genuinely hands-on environment, and you'll see your work go from schematic to shipped product in the field.

They're now looking for an Electronics Engineer to join their Hardware and Platform teams, working on high-reliability IoT edge systems deployed in demanding, real-world conditions - in a market set for significant growth over the next decade.

What you'll be doing

Designing embedded electronic hardware for IoT edge systems - microcontrollers, memory, power management, sensors and comms interfaces
Shaping system-level architecture, hardware requirements, and technology choices for new and existing products
Producing schematics and PCB layouts in ECAD tools, and keeping design documentation in good order
Selecting and qualifying components with an eye on performance, reliability, cost, and long-term availability
Designing and optimising low-power, battery-powered systems built for long field life
Integrating wired and wireless comms interfaces and radio modules
Leading prototype bring-up, debugging, and board-level fault finding
Working closely with Hardware QA on verification, validation, and compliance testing
Applying good design practice for EMI/EMC, electrical robustness, and long-term reliability
Supporting manufacturing and supply chain - pilot builds, supplier engagement, production troubleshooting
Contributing to Design for Test, Manufacture, and Reliability initiatives
Getting involved in design reviews, risk assessments, and continuous improvement (including ISO 9001)

What you'll bring

Essential:

A Bachelor's degree in Electronic Engineering or a related discipline
5+ years' professional experience in embedded hardware or electronics design
Solid schematic capture experience, and comfort with ECAD libraries and component management
A track record of designing and optimising low-power devices
Familiarity with circuit simulation, analysis, and optimisation tools
Experience with in-circuit test, JTAG, and hardware debugging tools
Strong fault-finding and root-cause analysis skills
Some exposure to component selection, microcontroller operation, and analogue/digital sensor interfacing
Strong analytical, problem-solving, and communication skills

Nice to have - they're happy to help you build these:

PCB design and layout experience
Hands-on prototyping and breadboarding skills
Experience integrating communication modules, or with RF circuit design/antenna selection
Understanding of EMI/EMC best practice, signal integrity, or power integrity
Experience designing industrial or infrastructure-focused IoT systems (sensors, gateways, remote monitoring)
Familiarity with PADs Pro or DX Designer
Exposure to embedded firmware development
Familiarity with environmental, electrical safety, or compliance testing
Experience with Agile/iterative development, Jira, or Confluence
Awareness of functional safety, reliability engineering, or product security principles
