• Help integrate sensors and devices (e.g., cameras, drones, LiDAR sensors) into the platform
• Build and maintain REST APIs, background tasks, and Kafka consumers for event-driven workflows
• Write clean, well-documented, and testable code under guidance from senior engineers
• Participate in code reviews, sprint planning, testing, and deployments
• Help simulate and test distributed workflows using Docker and Kubernetes
• Collaborate using Git, GitHub, and Jira/Confluence within a CI/CD pipeline
