Original job description

Leidos Undersea Systems Division (USD) is seeking a Senior Systems Engineer to support the Environmental Acoustic Recording System (EARS) program at the Stennis Space Center in Mississippi. The primary focus of this position is to perform in-depth data analysis on EARS survey data and serve as the liaison between the engineering and analysis groups working on the project. This role requires a deep understanding of underwater acoustics, signal processing, and systems engineering principles. You will apply strong technical expertise to define complex undersea and maritime problems, weigh engineering tradeoffs, and convey this information to multidisciplinary teams with recommendations for improved capabilities.

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.

SUBSEAMSS If you're looking for comfort, keep scrolling. At Leidos, we outthink, outbuild, and outpace the status quo - because the mission demands it. We're not hiring followers. We're recruiting the ones who disrupt, provoke, and refuse to fail. Step 10 is ancient history. We're already at step 30 - and moving faster than anyone else dares.

Original Posting:

November 12, 2026 For U.S. Positions: While subject to change based on business needs, Leidos reasonably anticipates that this job requisition will remain open for at least 3 days with an anticipated close date of no earlier than 3 days after the original posting date as listed above.

Pay Range:

Pay Range $107,900.00 - $195,050.00 The Leidos pay range for this job level is a general guideline only and not a guarantee of compensation or salary. Additional factors considered in extending an offer include (but are not limited to) responsibilities of the job, education, experience, knowledge, skills, and abilities, as well as internal equity, alignment with market data, applicable bargaining agreement (if any), or other law.
