Senior Localization Algorithms Engineer – EKF & Multisensor Fusion

Hubble is building a global Bluetooth Low Energy (BLE) + satellite network that connects devices from anywhere on Earth. This groundbreaking infrastructure opens new frontiers for global connectivity—and with it, novel challenges in geospatial intelligence.

We’re seeking a Senior Localization Algorithms Engineer – EKF & Multisensor Fusion 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.

Responsibilities

• 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.

Qualifications

• 7+ years of hands-on experience in applied data science or statistical modeling roles outside of academia.
• 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, using AWS Redshift, AWS Athena or Trino/PrestoSQL to construct analytical datasets, with emphasis on advanced modeling, performance tuning, or orchestration.
• Ability to translate complex analytical findings into compelling visual narratives that inform strategic decisions, with an emphasis on proficiency in BI tools like Apache Superset or dashboard tools like Plotly.
• 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.
