Overview

Hydraulic / Pneumatic Test Technician Ontic, a leading licensor and manufacturer of complex engineering parts for the global aerospace and defence industries, are now recruiting for a Hydraulic / Pneumatic Test Technician to join our Operations team, where you’ll play a key role in the build, test and validation of complex assemblies to the highest aviation standards. This role will be based at our Staverton site in Gloucestershire.

Ontic is more than just a business, we’re a community of innovators who pride ourselves on fostering a culture where talent thrives, ideas flourish, and careers are built. We’re committed to excellence, driving us to continuously improve and adapt, ensuring that we remain at the forefront of our industry.

The Role

As a Hydraulic / Pneumatic Test Technician, you’ll take ownership of testing and fault diagnosis across a range of hydraulic, pneumatic and mechanical components, ensuring all work meets strict regulatory and customer requirements. Working from engineering drawings, specifications and detailed work instructions, you’ll carry out complex testing activities, interpret results and ensure full traceability throughout.

You’ll be relied upon as a technical expert within the team, supporting fault finding, strip-down and repair activities, as well as contributing to Engineering and Quality investigations. You’ll play an important role in resolving technical issues, improving processes and ensuring high standards of workmanship across the function.

Alongside hands-on testing, you’ll help maintain best practice within the team, supporting continuous improvement initiatives and ensuring compliance with all procedures, quality standards and safety requirements.

About You

At Ontic, our culture is integral to making sure we enjoy our work and deliver for our customers. While we look for the right skillset, we’re also looking for someone who will thrive within our recognition and empowerment culture.

You’ll be confident interpreting complex engineering drawings and specifications, with the ability to work independently and make sound technical decisions.

You’ll have proven experience in testing, fault diagnosis and working to tight tolerances, with a strong focus on quality, accuracy and traceability. Your attention to detail will be second nature, and you’ll be comfortable working in a fast-paced environment where priorities can shift.

You’ll also be someone who can contribute beyond your own work, supporting others, sharing knowledge and working collaboratively with Engineering, Quality and Operations teams. Experience with hydraulic testing environments is highly desirable, and any electrical knowledge would be an advantage.

Benefits

At Ontic we care about your financial, physical, and mental wellness so we offer a range of benefits to support this. We care about what matters to you and have a valued culture of recognition and empowerment, accompanied by benefits that support work/life balance.
