Signal Processing Scientist – Real-Time Signal Processing & Underwater Acoustics
Why This Is a Great Opportunity
This role offers the chance to work in a fast-paced, entrepreneurial environment where mathematical rigor meets cutting-edge systems development. Successful candidates collaborate with multi-disciplinary teams to address critical national security challenges, leveraging:
- Development of real-time signal processing code
- Post-processing of complex datasets, including diagnostics, forensics, and phenomenon investigation
- Design of acoustic modeling tools for system planning, e.g. via underwater acoustics physics models
- Hands-on at-sea testing of prototypes from concept to field deployment
By partnering with clients who prioritise innovation and hands-on technical leadership, researchers translate theoretical physics into practical technological solutions. Prototypes move rapidly from lab to live testing—an environment that rewards both disciplinary expertise and creative problem-solving.
About the Role
We seek a Signal Processing Scientist with deep expertise in underwater acoustics, detection theory, and design of signal processing algorithms. This position involves contributing to or leading the development of state-of-the-art systems through:
- Core technical contributions:
- Post-processing of noisy acoustic datasets with diagnostic forensics - Design of planning/adaptive tools for system acoustic performance``` - Leadership & integration:
- Technical and/or project leadership for system design, code integration, and customer-facing testing
