Localization Software Engineer

Who we are

Theseus is a defense technology company building visual positioning to solve reliability for the next 10 million drones. We’re laser focused on solving localization on today's GPS-denied battlefield because we think it’s the biggest blocker to physical intelligence on drones.

Our products are already being used in real operational environments today. We’re a small team with high ownership and accountability, and we’re looking for engineers who want to move fast, build against real-world constraints, and see their work deployed in the field.

The role

We’re seeking a Localization Software Engineer to help build that autonomy stack. You’ll work on visual positioning systems that improve the accuracy, robustness, and reliability of Theseus’ products across sensors, onboard compute, and drone platforms.

You will:

• Design and iterate on visual localization and positioning algorithms
• Build tooling and data pipelines that accelerate model and algorithm development
• Contribute to architecture decisions across the localization stack
• Test, debug, and iterate on your work in real-world conditions

Required qualifications

• Deep experience with SLAM, VIO, localization, sensor fusion, or a closely related robotics problem, through work or substantial personal projects
• Strong track record of ownership: you’ve built real systems, deployed them, tested them in the real world, and can clearly explain the technical tradeoffs you made

Preferred qualifications

• Strong robotics fundamentals, including frames, poses, calibration, estimation, and uncertainty
• Strong Python/C++ skills
• Experience taking research software to production on edge hardware
• Experience deploying software onto robots, drones, or other real-world hardware systems
• Experience with map matching, place recognition, visual odometry, factor graphs, or EKFs
