Job description

Description

Ready to make impactful contributions in GNSS-based navigation to improve the reliability, accuracy, and effectiveness of our nation’s strategic deterrent weapon systems?

Interested in modeling the effects of missile kinematics on GPS signal propagation and reception in large-scale test flights, and characterizing the performance of deployed flight hardware?

Eager to develop and evaluate forward‑thinking GNSS and alternative navigation solutions together with a dedicated, collaborative team, in order to tackle national security challenges?

Join us in the GNSS and SATRACK Systems Group

We are seeking an inquisitive, motivated data scientist to delve into flight test GNSS data, focusing on the post‑processed RF signal records collected during each test. By converting these records into clear, quantitative performance metrics, you will deliver recommendations that drive next‑generation navigation instrumentation.

In this role 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. Join a forward‑thinking team of satellite navigation specialists whose blend of algorithm development, data analytics, and custom hardware design directly supports the nation!

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
