Senior GNC Engineer

ABOUT THE TEAM

Anduril’s Tactical Recon & Strike (TRS) is a division building highly capable autonomous drones and solid rocket motors at scale. We transform products like Ghost, Anvil, Bolt, and Altius from early concepts into fully operational capabilities. Within TRS, our GNC team is at the forefront of tackling the most challenging navigation problems, specializing in the ground-up development of resilient GPS-denied navigation solutions that empower our autonomous platforms to operate reliably in the most demanding, contested environments. We are a vertically integrated team, taking concepts from ideation to software loaded on a vehicle and into flight testing in the same week, sometimes even the same day.

ABOUT THE JOB

This is a senior role for an Algorithm Developer (Localization/GNC) who thrives on building cutting-edge technology from scratch and seeing their creations immediately deployed in the field. You will be a central architect in shaping Anduril's technical moat in GPS-denied navigation, driving the development of core vision-based navigation (VBN) and advanced sensor fusion algorithms. While core techniques like VBN and Terrain Contour Matching (TERCOM) exist, your role will involve pioneering novel approaches and advanced fusion methodologies that push their performance boundaries.
You will apply algorithmic creativity to explore and develop a diverse suite of advanced navigation solutions, including:

• Robust vision-based navigation
• Advanced map matching algorithms
• Terrain contour matching (TERCOM)
• Celestial navigation
• High-fidelity state estimation using various Kalman filter types (Error-State, Invariant Filters)
• Fusion of diverse sensor modalities (IMU, EO/IR, Baro, ToF, Radar Altimeter, Star Trackers)

You'll contribute directly to building capabilities that include collaborative navigation, precision landing on moving or maritime vessels, and developing a common, resilient navigation stack for platforms ranging from submarines and helicopters to boats and trucks. Join a close, collaborative team where your insights will directly translate into software loaded on vehicles, with rapid flight testing opportunities across diverse, exciting test sites – from captive flights on various vehicles to remote, cool locations. If you're passionate about making an immediate, tangible impact on national security by developing the most advanced navigation solutions for contested environments, this is your opportunity.

WHAT YOU’LL DO

• Design, implement, and rigorously validate advanced GPS-denied navigation algorithms, including Vision-Based Navigation (VBN), advanced Map Matching, and high-fidelity sensor fusion for state estimation.
• Drive ground-up algorithm development from theoretical concepts through high-fidelity simulation, Hardware-in-the-Loop (HIL) testing, and rapid flight validation on multiple physical hardware platforms.
• Collaborate intimately with Computer Vision, Flight Software, and Simulation teams to define requirements, integrate solutions, and push the boundaries of autonomous navigation in contested environments.
• Analyze extensive flight test data from diverse platforms (e.g., Altius, Ghost, manned aircraft) collected across varied, challenging environments to identify performance gaps, refine algorithms, and debug complex incidents.
• Contribute strategically to the growth of Anduril's technical moat in navigation, including areas like collaborative navigation and precise terminal guidance for challenging operational scenarios.
• Mentor junior engineers and champion best practices in algorithm design, validation, and continuous integration within a fast-paced, high-impact environment.
