Responsibilities:
- Work alongside a senior developer to build a pipeline that ingests camera streams, passes frames through ML inference, and surfaces results in a web UI.
- Write clean, maintainable, and efficient code following SOLID/DRY and team standards.
- Build real-time UIs that visualize streaming data — live video, detections, charts, overlays, and dashboards.
- Implement backend services in Python to handle stream ingestion, orchestrate ML calls, and expose APIs to the frontend.
- Integrate with external services and APIs with proper auth, retries, timeouts, and error handling.
- Design and maintain database schemas, indexes, and migrations; optimize queries where it matters.
- Diagnose, reproduce, and fix bugs across the stack.
- Create and maintain documentation.
- Participate in code reviews and architectural discussions; propose improvements.
- Join team ceremonies and planning.
- Ensure data security and help mitigate vulnerabilities.
- Optimize server and application performance, especially around streaming and real-time data paths.
