Principal PNT & Timing Engineer - Space Constellation

Blue Origin LLC; United States; On-site; USD 170,000 - 237,000; Full time

Job summary

Blue Origin seeks a Principal Engineer for Position, Navigation, and Timing (PNT) to own timing and synchronization for the TeraWave constellation and to lead PNT resilience and R&D efforts. You will write estimation algorithms, build simulators, and drive architectural trades while shaping a focused PNT team within the Chief Systems Architecture office.

You will work cross-functionally with payload, flight software, ground, and network teams to ensure interfaces are well defined and verifiable,

Qualifications

• Bachelor's degree in Aerospace Engineering, Electrical Engineering, Physics, Mathematics, or related field; MS or PhD preferred
• 10+ years of experience in PNT systems, navigation algorithm development, or timing and synchronization engineering for satellite or distributed systems
• Hands-on experience developing estimation algorithms for orbit determination, clock estimation, or sensor fusion.
• Working knowledge of time transfer methods and clock characterization
• Experience with GNSS-based navigation and an understanding of performance under degraded or denied conditions
• Proficiency in MATLAB and/or Python for algorithm development, simulation, and analysis
• Demonstrated ability to frame and close architectural trades scoping the question, identifying binding constraints, and documenting defensible outcomes
• Strong technical communication skills able to present PNT architecture and trade results clearly to both domain specialists and program leadership

Responsibilities

• Define timing and synchronization architecture for the TeraWave constellation.
• Develop and validate PNT estimation algorithms (orbit, clock, sensor fusion).
• Build simulation frameworks to characterize estimation filter performance and timing stability.
• Conduct architectural trades across PNT approaches and document outcomes.
• Define PNT resilience posture for operations under degraded conditions.
• Develop execution plan and build case for a focused PNT team.
• Collaborate with payload, flight software, ground, and network teams to verify interfaces.
