Ask HN: Who is hiring? (December 2025)

We're making crop insurance accessible to farmers worldwide. Our platform helps major insurers monitor 10M+ hectares across 10+ countries using satellite imagery and ML — so farmers can manage the volatility of their industry.

You'll build web & mobile apps that agronomists use daily in the field (offline-capable, rough conditions), work on data-heavy features cramming gigabytes into mobile apps, and help shape product decisions with real autonomy.

Stack: TypeScript, React/React Native, PostgreSQL/PostGIS, Python + GDAL/NumPy for satellite imagery processing.

Small remote-first team, wear multiple hats. Quarterly in-person meetups.
