Electronics & Embedded Systems Engineer

Overview

A fast-growing UK clean-energy start-up is developing an innovative domestic thermal energy storage system. As they move from prototype to pre‑production, they are seeking an experienced Electronics & Embedded Systems Engineer to take ownership of the full control‑electronics design for a safety‑critical, mains‑powered appliance designed for UKCA/CE certification and future volume manufacture.

• Define overall electrical & control system architecture
• Select MCU / embedded platform (e.g. STM
  32, NXP, ESP
  32)
• Develop power distribution & protection strategy
• Integrate sensors, actuators, heaters & communication interfaces

• Schematic capture & multi‑layer PCB layout
• Industrial, manufacturable design (DFM/DFA principles)
• Component selection with availability, cost & reliability in mind
• Design for EMC, thermal performance, and safety compliance

• AC mains interfacing and load/heater control
• Use of relays, SSRs or contractors as appropriate
• Implement isolation, fusing, grounding & fault‑detection strategies
• Design aligned with CE/UKCA safety and compliance requirements

• Develop firmware architecture and core control logic
• Implement local/remote communications
• Diagnostics, fault handling & firmware update strategy

• Support prototype builds and system bring‑up
• Hands‑on debugging & optimisation
• Close collaboration with mechanical & systems engineering teams

• Optimise design for manufacturing & assembly
• BOM optimisation
• Support pre‑compliance testing and certification processes
• Produce handover documentation for manufacturing partners

• Proven experience designing mains‑powered electronics
• PCB design for domestic or industrial appliances
• Embedded firmware development (STM
  32, NXP, ESP
  32 or similar)

This is a key role within a highly technical engineering team, ideal for an Electronics & Embedded Systems Engineer who enjoys full life cycle ownership and wants to shape a next generation low carbon technology.

We are committed to equal opportunity and diversity.
