Summary
Do you have hands-on experience with Matlab/Simulink modelling and underwater acoustic testing?
Can you demonstrate your ability to specify, set up, and analyse acoustic or vibration instrumentation in complex engineering environments?
Are you ready to apply your acoustic expertise to one of the most technically advanced defence projects in the world, where your work directly contributes to the performance and stealth of next-generation submarines?
The Opportunity
An exciting opportunity has arisen for a Contract Acoustics Engineer (Outside IR35) to join a high-profile defence project during a period of growth and expansion.
This role will see you applying your specialist knowledge of noise, vibration, and acoustic signatures to support the design, testing, and performance optimisation of submarine systems. You’ll be part of a collaborative engineering environment that values innovation, technical excellence, and professional development.
- Outside IR35 contract engagement.
- Opportunity to contribute to world-class submarine engineering projects.
- Exposure to advanced modelling, testing, and acoustic analysis.
- Supportive and inclusive culture, promoting professional growth and development
Your duties and responsibilities will be:
- Provide specialist advice and direction on submarine noise, vibration, and acoustic signatures performance.
- Conduct analytical and numerical modelling of acoustic and vibration phenomena.
- Carry out data collection, testing, analysis, and reporting—including on-site, supplier, and at-sea trials.
- Produce and review engineering documentation such as specifications, test procedures, safety assessments, and technical reports.
- Investigate and resolve signatures and vibration issues from in-service vessels, identifying and implementing corrective actions.
- Support system updates, life extensions, and upgrades across the submarine fleet.
- Provide engineering authority and advice across internal teams and stakeholders.
You will have the following qualifications & experience:
- Degree or HNC/HND (or equivalent) in Mechanical, Aerospace, or related Engineering discipline.
- Matlab/Simulink modelling and simulation.
- Instrumentation specification, setup, and data acquisition.
- Development testing in underwater environments.
It’s great if you also have the following
- Background in acoustic or sonar systems engineering.
- Strong technical documentation and reporting skills.
- Excellent communication and teamwork abilities.
- Experience in continuous improvement and innovation.
- Proficiency with standard office and analysis software.
