Primary Responsibilities:

Review and analyze complex survey datasets, identifying events and trends of scientific or operational interest.

Perform quality control on survey datasets to identify potential system engineering issues.

Report complex technical findings from survey data to the engineering and analysis teams. Collaborate with the teams to investigate and troubleshoot each issue.

Review and collaborate on engineering developments to ensure all system requirements are met.

Assist in the development of new analysis tools.

Validate ambient noise products for accuracy.

Compile clear technical reports which present complex acoustic findings to various audiences.

Required Qualifications and Skills:

Must be a US citizen.

Must have an active TS/SCI clearance.

Doctorate degree in Physics, Mathematics, Systems Engineering, or a related discipline with at least 15 years of relevant experience.

Strong foundation in mathematics, physics, and engineering.

Demonstrated experience solving complex technical problems in one or more relevant fields, such as acoustic or sonar signal processing, algorithm development, modeling and simulation, or detection and estimation theory.

Working knowledge of underwater acoustic theory.

Demonstrated proficiency in MATLAB.

Excellent communication skills with the ability to translate complex concepts to audiences with varying technical backgrounds.

Strong problem-solving skills.

Ability to work independently with minimal supervision.
