Senior Software Engineer - Geospatial

Ocient is a company specializing in analytical databases with a focus on geospatial capabilities. They are seeking a Senior Software Engineer to enhance their geospatial engine, working on various aspects of spatial analysis and performance optimization.

Responsibilities:

• Core spatial engine. Extend and harden the 120+ geospatial function library across accessors, constructors, measures, predicates, spatial operators, spatial relationships, transformations, and parsers/formatters (WKT, WKB, EWKT, GeoHash)
• Spherical correctness. Work on the numerical correctness of non-Euclidean computation on both the spherical and spheroid WGS84 models: geodesics, great-circle distance, area on a sphere, antimeridian and pole handling, degenerate and near-degenerate geometries, and precision behavior at very small and very large scales
• Performance and indexing at hyperscale. Make spatial predicates, joins, and range queries fast across trillion-row datasets: spatial indexing, pruning and partitioning strategies, bounding-volume acceleration, vectorized evaluation, and planner integration so spatial filters push down correctly
• Spatiotemporal analytics. Deepen the space-and-time operator set; trajectory reconstruction, interpolation along linestrings over time, and movement and co-location analysis
• Convergence with the rest of the engine. Help connect geospatial to Ocient's other analytical surfaces, spatial clustering, accelerated nearest-neighbor search over geographic data, and in-database ML, so spatial and non-spatial analysis compose in a single query and not separate systems
• Customer-driven scope. Geospatial shows up across the industries we target; telco (CDR and cell tower analysis), adtech (geo-targeting), and national security (ISR and movement analysis at scale). You'll work with Product and customer-facing teams to turn those workloads into engine capability
• Collaboration and craft. Write clear design docs, tests, and documentation so spatial behavior is explicit, benchmarked, and protected against regressions

Requirements:

• 5+ years building production software systems, including solid experience in C++ (or comparable systems-level work with a willingness to work primarily in C++)
• Solid grasp of computational geometry and, critically, spherical/geodetic geometry – you understand why a great-circle distance is not a Pythagorean one and what breaks when you pretend otherwise
• Exposure to geospatial data, standards, or libraries: WGS84 and geodetic datums, OGC/WKT/WKB, GEOS, S2, H3, PostGIS, or equivalent
• Comfort with performance engineering such as profiling, algorithmic optimization, and reasoning about work at scale
• Strong instincts around numerical correctness and edge cases, and the discipline to encode them in tests and documentation
• Ability to work across teams and codebases and turn ambiguous requirements into concrete solutions
• Experience implementing spatial indexing or spatial query optimization inside a database or query engine
• Background in trajectory analysis, spatiotemporal data management, or moving-object databases
• Experience with large-scale data systems, analytical databases, query planners, or distributed execution
• Familiarity with in-database ML, or with optimization and spectral methods applied to geographic problems
• Domain experience in one of our target verticals such as telco, network analysis, adtech, automotive/mobility, aviation, logistics, or government/geospatial intelligence
