Sentinel Defense Technologies

Sentinel Defense Technologies is building real-time civilian threat intelligence for conflict zones. We have a working system: Django backend live, Flutter apps approved on App Store and Play Store, a multi-gate AI pipeline processing OSINT, and an admin console with human-in-the-loop verification. The team has begun an operational pilot with Winrock International for counter-trafficking intelligence in Southeast Asia. Role: Founding Product Engineer / Systems Architect. You will own the Django backend, MongoDB schemas, and the Flutter UI that connects them. The AI pipeline lead handles Gemini orchestration; your job is to own the data layer, build the API surface, and wire it into the offline-first client. Must be an end-to-end builder who cares about civilian interactions in crises. Must-haves: Python/Django, MongoDB, Flutter (or ability to pick up quickly), and system design thinking. Strong plus: DevOps (Docker, AWS), LLM integration, OSINT, geospatial. They also welcome strong full-stack implementation engineers who ship fast and want founding-team equity.
