You should have a solid understanding of vehicle systems and testing methodologies, along with the ability to analyse technical data, coordinate testing activities, and communicate findings clearly to a range of stakeholders.

A hands-on approach, strong problem-solving skills, and the ability to work independently while supporting colleagues across multiple projects are essential.

 * Experience of commercial vehicle, bus, or coach development and testing.

## Description

We design, deliver, and support market-leading buses and coaches that help reduce emissions, improve air quality, and keep communities connected. Every role contributes to that mission whether you're engineering, driving sales, improving production, or supporting our customers.

What You'll Do
As an Engineer within our Test Development team, you'll play a key role in delivering vehicle, chassis, structural, and component testing programmes that support the development of innovative bus and coach products. Working on projects ranging from in-service failure investigations through to full vehicle validation and supplier sign-off activities, you'll ensure that systems and components perform safely, reliably, and in line with technical and legislative requirements.

This is a highly practical role that combines hands-on testing, project coordination, data analysis, technical reporting, and collaboration with internal teams, suppliers, and external test facilities.
