Job summary

General Motors (GM) is seeking a Senior Software Engineer for its Mapping Engineering team in Sunnyvale, CA. You will design and implement mapping algorithms and geospatial data systems for automated map reconstruction and maintenance, owning the end-to-end lifecycle from data to production.

You will work with perception, localization, and simulation teams, apply machine learning to feature extraction, and build scalable pipelines for road networks, lanes, and topology.

Qualifications

• 3+ years of software engineering experience building production systems with a focus on mapping, geospatial, or geometric algorithms.
• Strong foundation in geospatial and computational geometry concepts—coordinate systems and projections, spatial indexing, geometry operations, map matching, and graph algorithms on road networks.
• Experience designing geospatial data models and working with road network or map data structures (lanes, segments, intersections, topology).
• Hands-on experience with machine learning or computer vision workflows in production—dataset curation, model training or fine-tuning, evaluation, and deployment.
• Experience building large-scale distributed data pipelines for geospatial or sensor data.
• Proficiency in Python and C++.
• BS or MS in CS, GIS, Electrical Engineering, Robotics, or related technical field, or equivalent industry experience.

Responsibilities

• Design and implement mapping algorithms for map reconstruction and maintenance — lane and boundary extraction, road network graph construction, map conflation and matching, geometry simplification, and topology validation.
• Build and evolve geospatial data models for lane-level connectivity at intersections, road network graphs, and associated map attributes and restrictions.
• Develop large-scale distributed geospatial pipelines that process sensor-derived and third-party road data into production map releases on a recurring cadence.
• Apply machine learning and computer vision models — detection, segmentation, 3D reconstruction, BEV representations — to automate feature extraction and map change detection, and integrate them into production pipelines.
• Build automated quality, validation, and regression systems that catch geometric, topological, and semantic map defects before release, with clear accuracy metrics.
• Collaborate cross-functionally with Perception, Localization, Simulation, and Platform teams on interfaces, data contracts, and integration points.
• Diagnose and resolve system-level issues spanning geospatial data pipelines, algorithms, models, and production workflows.
• Contribute to design reviews, engineering best practices, and mentorship of engineers on the team.
