We are looking for an experienced IoT / OT Infrastructure Engineer to join a global IoT and Smart Buildings programme supporting a Tier 1 financial institution. The programme involves migrating non-PC devices across offices worldwide—including air quality sensors, occupancy sensors, smart lighting systems, CCTV cameras, printers, and building-adjacent systems—onto a dedicated SD-Access fabric that is fully segregated from the corporate network. This is an established, live programme operating across multiple global regions, with additional sites continuously being migrated. The successful candidate will join a small, senior engineering team and must be comfortable owning technical issues independently, troubleshooting across application and infrastructure layers, and coordinating with multiple technology and vendor teams.

Key Responsibilities
- Onboard, configure, and troubleshoot IoT devices including occupancy sensors,



air quality monitors, smart lighting, CCTV systems, printers, and other building-connected devices.
- Manage devices from initial deployment and onboarding through configuration, reliable operation, and eventual decommissioning.
- Administer and troubleshoot Linux and Windows servers hosting IoT application services.
- Monitor broker services, analyze application logs, and troubleshoot issues affecting device-to-cloud data flow.
- Work with MQTT brokers such as Mosquitto and EMQX to diagnose application-layer connectivity and messaging issues.
- Manage firmware updates, configuration deployments, device certificates, and certificate lifecycle activities.
- Troubleshoot IoT endpoint connectivity in collaboration with network, security, proxy, firewall, and vendor teams.
- Support building migrations by coordinating with facilities engineers and internal technology teams.
- Validate end-to-end connectivity
