The Opportunity

Copello are supporting a leading Defence client in their search for a Test & Testability Expert to play a key role in shaping how systems are tested across their full lifecycle — from early concept through to production and in-service support.

You'll report into the Head of Test & Testability, with strong project links to the Project Chief Design Engineer, and act as a Subject Matter Expert across multiple programmes.

As part of the Test & Testability Architecture team, you'll help define smarter test strategies, improve Built-In Test architectures, and raise the quality and consistency of test specifications across projects — removing waste and focusing effort where it adds real value.

This is a senior, influential role where your technical expertise will directly shape product quality, efficiency, and ways of working.

What You'll Be Doing

* Own and define project test strategies and BIT architectures, including coverage requirements

* Improve how test equipment requirements and specifications are written across programmes

* Lead analysis of production test data to identify trends and diagnose failures

* Model and analyse system test coverage and generate diagnostic instructions

* Drive continuous improvement in ways of working across Test & Testability

* Support Red Team reviews and critical issue resolution during development and manufacture

* Support new product bids and early feasibility studies

* Identify, document, and deploy best practice across the department

* Mentor and support engineers within the Test & Testability team

* Contribute to and lead technology and capability roadmaps

What We're Looking For

* Degree-level education (or equivalent experience)

* Significant experience in electronic test across the full project lifecycle

* Strong background in:

* Electronic circuit design, test, and failure analysis

* Test equipment design

* Requirements capture and specification

* Design for Test (DfT) and testability

* Proven ability to provide technical leadership across complex design projects

* Experience influencing senior technical and business stakeholders

* Willingness to travel within the UK and EU when required
