• Build services for real‑time data ingestion, processing and storage, ensuring high throughput and fault tolerance.
• Collaborate with hardware and firmware teams to integrate IoT edge devices into cloud‑based services.
• Debug and troubleshoot complex distributed systems, including interactions between backend APIs, IoT gateways and edge devices.
• Ensure observability by implementing logging, monitoring and tracing frameworks (e.g., Jaeger, Prometheus).
• Participate in Agile development processes including backlog grooming, sprint planning, code reviews and retrospectives.
• Mentor junior developers and contribute to engineering standards and best practices.
• Collaborate with DevOps to ensure smooth CI/CD pipelines and containerized deployments in Docker/Kubernetes environments.
