GNSS Data Science and Navigation Analyst

About the role

Join the GNSS and SATRACK Systems Group to make impactful contributions in GNSS-based navigation to improve the reliability, accuracy, and effectiveness of our nation's strategic deterrent weapon systems. You will delve into flight test GNSS data, focusing on post‑processed RF signal records collected during each test, converting these records into clear, quantitative performance metrics, and delivering recommendations that drive next generation navigation instrumentation. You will conduct in‑depth assessments, devise innovative algorithms, and team with multidisciplinary experts to define instrumentation and sustainment requirements that keep our systems aligned with the nation's evolving strategic deterrence objectives.

Responsibilities

• Analyze GNSS data to extract detailed insights of navigation performance for various missions, through predictive analytics, data engineering, and visualization
• Evaluate emerging GPS and GNSS technology (e.g., GPS modernization, contested-environment operation, alternate navigation options) and translate into recommendations
• Develop your proficiency in navigation satellite signal physics and receiver technology
• Lead cross-functional teams to respond to sponsor needs
• Implement, build, and enhance innovative algorithms as we improve our simulation and data science tools to deliver insightful analysis
• Build team knowledge-base and collaborate with staff across all experience levels, establishing yourself as a technical authority on satellite-based positioning applications

Qualifications

You will meet our minimum qualifications if you:

• Hold a B.S. in a quantitative or engineering field such as Data Science, Applied Physics, Computer Science, Electrical Engineering, Aerospace Engineering, or Mathematics
• Demonstrated track‑record of systematically exploring innovative ways to improve the fundamentals of navigational accuracy through predictive analysis and data engineering
• Have at least 8 years of technical experience and at least 5 years of exposure to a navigation-related field
• Proficient in at least one scientific programming language such as Python, MATLAB, or C/C++
• Established ability to engage both technical experts and program management, and document sophisticated technical analysis with compelling reports, briefings, and visualizations
• Are able to obtain a Secret security clearance by your start date and can ultimately obtain a Top Secret level clearance. If selected, you will be subject to a government security clearance investigation and must meet the requirements for access to classified information. Eligibility requirements include U.S. citizenship

Preferred qualifications

• Hold an M.S. or Ph.D. in a relevant subject area
• Possess a minimum of 10 years engaged in GNSS navigation or alternative Position Navigation and Timing systems
• Have a solid foundation in statistical data analysis, Kalman filtering, signal propagation physics, and/or machine learning
• Possess software development experience with a focus on Matlab and Python, including use of Git/GitLab with Continuous Integration
• Are familiar with the strategic deterrence mission
• Have demonstrated project leadership and mentoring skills
• Hold an active Top Secret level clearance
