We’re partnering with an AgTech & Sustainability innovator that is redefining how technology supports regenerative farming.
Their mission: develop smart solutions for virtual fencing and ultra-high-density grazing that make a real impact on sustainability and animal welfare.

- Integrate securely with the Python backend (REST APIs, auth, data models)
- Set up and maintain CI/CD, TestFlight, crash reporting, analytics, and rollout configs
- Implement field-ready features including offline workflows and geofencing
- Use AI-assisted tools (Cursor, Claude Code, LLMs) for development, testing, and documentation
- Monitor app health, analyze user data, fix issues, and iterate based on feedback
- Document architecture, interfaces, and operational procedures
