Software Engineer - Onboard Maps and State Estimation

Job description

Job responsibilities

• Own the onboard live-map estimator end to end: fuse HD map priors with live perception into a single, real-time estimate of the world the rest of the stack can trust
• Build our onboard map change detection: classify situations like boundary shifts, stop-line moves, and road closures from the divergence between map and perception, and define when the planner should stop trusting the…
• Define the map trust contracts the planner builds against: confidence semantics, degraded-mode behavior, and the operating points that hold across vehicle programs
• Build the evaluation backbone, ground-truth and metrics pipelines, operating points, and regression testing that keep estimator and detector quality from silently drifting
• Ship estimation code in modern C++ that meets real-time budgets on embedded compute
• Extend the loop offboard over time: aggregate divergence detections across fleet drive logs into map freshness and correction pipelines

Job requirements

• Bachelor's degree in Computer Science or equivalent
• 5+ years building production software, including at least one shipped system where they owned the estimation core
• State estimation fundamentals proven in production: factor graphs and/or filtering, data association, uncertainty representation and propagation, and 3D geometry and transforms
• Experience fusing heterogeneous sources such as prior map data, perception output, and raw sensors, into a single world estimate, with rigorous error characterization
• Strong modern C++ and the ability to make estimation code meet real-time budgets on embedded compute
• Rigorous evaluation practice: has built ground-truth or metrics pipelines and used them to hold a shipped operating point and prevent regressions
• Judgment about uncertainty: understands the difference between an error that degrades gracefully and one that is catastrophic, and designs the system accordingly
• Experience defining a system and its interfaces and negotiating those contracts with consumer teams
