Senior ECU & Electronics Hardware Engineer

Advanced EV, Battery & Powertrain Systems

Overview

We are recruiting a Senior ECU & Electronics Hardware Engineer to join a established engineering organisation developing next‑generation electric powertrain and battery technologies. This role sits at the intersection of advanced EV systems and motorsport‑pace engineering, delivering real hardware into real testing and deployment environments.

This is not a software‑only or late‑stage production role. You will design, build, test and own ECU‑level hardware used within battery management systems, powertrain control and supervisory electronics. The work is hands‑on, technically demanding and safety‑critical, supported by long‑term investment and organisational scale.

The Role

You will take end‑to‑end ownership of ECU and electronic control hardware, from early concept and architecture through schematic, PCB design, bring‑up, validation and production release. Alongside hardware delivery, you will play a key role in developing and supporting Hardware‑in‑the‑Loop (HIL) systems used to validate EV battery and powertrain architectures.

The environment is fast‑paced and prototype‑led, but with the structure, funding and stability of a major global engineering organisation. Engineers in this team work closely with firmware, software, systems and test teams to deliver robust, high‑performance solutions.

Key Responsibilities

Lead ECU and electronic hardware design from concept through to production
Design mixed‑signal, safety‑critical control and interface boards
Perform circuit design, simulation, schematic capture and PCB layout oversight
Own board bring‑up, debugging and fault diagnosis using lab equipment
Develop, support and debug ECU‑connected HIL rigs
Support battery, powertrain and control hardware during lab, rig and test activities
Apply high‑voltage‑aware design principles, including isolation, creepage and clearance
Select components with consideration for EMC, thermal and reliability requirements
Define and execute hardware test strategies, including EVT, DVT and PVT
Work closely with embedded firmware and software engineers to deliver integrated systems
Mentor junior engineers and contribute to continuous improvement of team processes

Technical Requirements

Grounding strategies and transient protection
Familiarity with functional safety principles
Experience applying DFMEA and hardware verification methods
Exposure to automotive or motorsport‑grade design standards

Ideal Background

Automotive, EV, motorsport or advanced engineering environments
Prototype‑heavy, fast‑moving programmes
Experience delivering hardware against demanding technical schedules

Seniority Expectations

Leads designs end‑to‑end with minimal supervision
Comfortable making architectural and technical trade‑offs
Drives design reviews and delivery timelines
Acts as a mentor and technical reference for others
Takes ownership for outcomes, not just tasks

Package & Benefits (UK)

Competitive base salary: £60,000-£70,000 (higher for Lead/Principal profiles)
Annual bonus scheme
Pension with strong employer contribution, increasing with service
Share / SIP scheme
Private medical insurance and health cash plan
Life assurance and income protection
Free on‑site gym and discounted national memberships
Electric car salary sacrifice scheme
26 days holiday plus bank holidays, with option to buy additional days

Working Pattern

Predominantly on‑site role due to lab, rig and prototype requirements
Typically 4-5 days on site, with limited flexibility for remote design or admin work
Occasional extended hours aligned to testing or integration milestones
Minimal travel, primarily UK‑based test facilities

Why This Role

This position offers genuine ECU hardware ownership, advanced EV and battery exposure, and the pace of motorsport engineering combined with long‑term stability and investment. It is suited to engineers who want to design, touch, test and improve real hardware - not manage it at arm's length.
