Remote Senior Geospatial Software Engineer — Hyperscale GIS

Ocient; United States; On-site; USD 165,000 - 190,000; Full time

Job summary

Ocient is hiring a Senior Software Engineer to extend the geospatial engine and own end-to-end features from spherical math correctness to query performance at hyperscale. This is a hands-on role on a small team with a broad surface area, requiring deep C++ expertise and strong attention to numerical correctness.

You will work on core spatial libraries, geodesic accuracy, and advanced indexing and analytics, collaborating with cross-functional teams to deliver end-to-end, in-database geospatial

Qualifications

• 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.
• 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.

Responsibilities

• Core spatial engine work: 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).
• Geodesic correctness: address geodesics, great-circle distance, and WGS84 model handling with edge-case considerations.
• Performance and indexing at hyperscale: optimize spatial predicates, joins, range queries, and vectorized evaluation.
• Spatiotemporal analytics: deepen space-and-time operators, trajectory reconstruction, and movement analysis.
• Engine integration: connect geospatial features with other analytical surfaces and in-database ML.
• Collaboration: write design docs, tests, and documentation to prevent regressions.
