- AI Experiences — Conversational 3D avatars, kiosk assistants, voice interfaces, RAG-based client knowledge systems, visitor analytics and AI agents.
- Immersive Installations — Interactive touch walls/tables, projection mapping, gesture and motion tracking, AR/VR/MR showcases and real-time 3D experiences.
- IoT & Hardware Integration — Sensors, cameras, RFID/NFC, beacons, lighting, relays and media players integrated with REDS™ OS.
- Automation & Show Control — Event-driven workflows, scheduled triggers, device health monitoring, alerts and internal operations tooling.

Key Responsibilities

- Integrate IoT devices and hardware using MQTT, WebSockets, REST, Serial, OSC, DMX/Art-Net and Modbus.
- Develop device-side applications where required using Raspberry Pi, ESP32 or Arduino.




- Build event-driven automation, show-control sequences, scheduled content and device monitoring systems.
- Develop real-time and offline-first systems capable of operating during network interruptions and synchronising when connectivity returns.
- Containerise services using Docker, implement CI/CD and deploy to AWS and in office edge devices.
- Convert creative designs into pixel-accurate, responsive and high-performance interfaces, from mobile screens to multi-panel LED walls.
