Principal Localization Engineer – Location Intelligence

Location: San Francisco, California, United States

Department: RF Payload (Commercialization) - Software

 

ABOUT THIS ROLE

Hybrid role based in Seattle, WA or San Francisco, CA

We're seeking a Principal Localization Engineer to lead the development of robust location computation systems leveraging Hubble's dual-stack BLE + satellite telemetry. This is a highly technical and strategic role focused on solving complex state estimation problems at scale. You'll work cross-functionally with signal processing experts, firmware engineers, and data infrastructure teams to push the limits of what's possible in dynamic, global-scale environments.

This role has high visibility and direct impact on our core product performance and customer acquisition.

RESPONSIBILITES 

• Architect and implement cutting-edge location estimation algorithms based on BLE and satellite data, including Kalman filters, Extended Kalman Filters (EKF), and Particle Filters.

• Optimize for computational efficiency, real-world performance, and cost — balancing precision with system constraints.

• Build and deploy production-grade statistical and probabilistic models for state tracking and error correction.

• Partner with Data Engineering to define data collection, structuring, and processing pipelines that support robust modeling.

• Evaluate and iterate on models based on live system performance and simulation feedback.

• Collaborate with cross-functional stakeholders, including embedded systems and backend infrastructure teams, to ensure end-to-end feasibility and integration.

REQUIRED QUALIFICATIONS

• 7+ years of hands-on, industry experience in applied state estimation, robotics, or signal processing roles.

• Deep expertise in state estimation and sensor fusion, with practical implementation of Kalman, EKF, or Particle filtering techniques.

• Strong understanding of geolocation systems, signal propagation models, and statistical inference under uncertainty.

• Proven track record of bringing algorithms from prototype to production in real-world, resource-constrained systems.

• Strong foundational SQL skills (AWS Redshift, AWS Athena, or Trino/PrestoSQL) to pull and validate analytical datasets.

• Strong Python programming skills, with emphasis on numerical methods, simulation, and performance optimization.

• Experience working closely with data engineering teams or building pipelines to support analytical model development.

• Strong communication skills and the ability to synthesize complex technical ideas for both technical and non-technical audiences
• All applicants must be U.S. citizens or lawful permanent residents (“green card holders”) as defined by ITAR (22 CFR §120.15)

PREFERRED QUALIFICATIONS

• Background in robotics localization, GN&C, autonomous systems perception, or RF geolocation is a strong plus.
