Full-Stack IoT Developer

Role Description

This is a contract hybrid role for a Full-Stack IoT Developer based in Calgary, AB, with some flexibility for remote work. We're looking for a developer who is genuinely comfortable across the full stack — embedded firmware, cloud infrastructure, and mobile frontend. You won't specialize in one layer; you'll own features end-to-end and make pragmatic decisions at every level.

If you're a web developer curious about IoT, this is not the right fit. If you've flashed a microcontroller, debugged a protocol with a logic analyzer, and shipped a cloud-connected product, keep reading.

We are looking for recent and soon-to-be grads from postsecondary institutions who want to get their foot in the door in their industry.

• LoRa/LoRaWAN integration for low-power, long-range device communication
• OTA firmware update pipelines with rollback and failure recovery
• AWS IoT Core device fleet management and Lambda-based data processing
• Supabase backend — Postgres schema design, RLS policies, Auth, and Realtime
• REST API design and MQTT-based device-to-cloud messaging
• React Native mobile dashboard with real-time sensor visualization

• ESP
