🪄 Skills: PostgreSQLPythonFrontend DevelopmentFull Stack DevelopmentGitMachine LearningReact.jsAPI testingReactCI/CDRESTful APIsJSONData visualization

Requirements:

Deep experience with React, including component architecture, state management, and styling frameworks.
Familiarity with Mapbox, Leaflet, or other map tile or rendering libraries.
Working knowledge of Python, especially for integrating with APIs or writing lightweight backend logic.
Comfortable working with RESTful APIs, JSON payloads, and asynchronous calls.
Some experience with relational databases like PostgreSQL or MySQL.
Ability to quickly prototype, test, and revise interfaces with minimal supervision.
Comfort with version control workflows and basic CI/CD tooling (e.g., GitHub Actions).

Responsibilities:

Rapid Prototyping: Take ideas from whiteboard to working demo in days — not weeks. Build and iterate on new products and features using lightweight frontends and LGND’s backend APIs.
Frontend Development: Build rich, spatially aware interfaces using React, including map-based UIs (e.g., Mapbox), data visualizations, and lightweight dashboards.
API Integration: Work almost entirely against APIs, integrating LGND’s services and MCP servers, as well as third-party geospatial services.
Backend Collaboration: Write or modify small backend components using Python, especially for internal tooling or lightweight extensions to our existing APIs.
Infrastructure-Aware UI: Build frontends that are responsive to real-world compute and data infrastructure constraints — particularly when working with large spatial datasets or ML workflows.
UX Experimentation: Help evaluate UX for interacting with embeddings, vector search results, and spatial metadata. Propose new patterns where needed.
Cross-functional Collaboration: Work alongside AI engineers, backend developers, product leads, and researchers to translate technical workflows into intuitive interfaces.
Speed & Flexibility: Adapt quickly in a fast-moving startup environment where priorities evolve and experimentation is encouraged.
