Job summary

Orcrist Technologies GmbH is building a next generation data intelligence platform. We are developing AirSpot, a mobile app for reporting drone sightings used by law enforcement and defense teams.

You will join an early team, co-own the architecture, and take the product from an early stage to production-grade.

• Strong React Native, TypeScript, and Expo experience, including the New Architecture (Fabric, TurboModules, Bridgeless).
• Experience with mobile performance, testing, observability, and production releases.
• Hands-on experience with MapLibre, Mapbox, Google Maps, or comparable mobile mapping technologies.
• Evidence of owning architecture or major technical decisions, not just implementing predefined features.
• Strong engineering judgment and the ability to work independently in a small team.
• University-level technical education in computer science, software engineering, or a related field.
• Eligible to work in Germany and, where required, for EU/NATO security clearance.

Responsibilities

• Own architectural decisions across state management, data fetching, offline behavior, navigation, and the mobile build/release pipeline.
• Build geospatial experiences with MapLibre, including real-time location and map interactions.
• Improve performance and reliability across startup time, animations, lists, memory, battery, and crashes.
• Establish reliable testing with Jest, React Native Testing Library, and Maestro.
• Own production delivery with EAS, including builds, signing, releases, and app store readiness.
• Contribute to backend APIs when useful and help establish engineering standards as the team grows.
• Use AI-assisted development tools to accelerate delivery without compromising quality.
