Senior IoT System Eningeer/Architect
Role Title: Senior IoT System Engineer / Architect Employment Type: Contract Duration: 6 months to start Preferred Location: Midwest Role Description: The Senior IoT System Engineer / Architect is a senior technical leader within the Technology & Architecture team for Connected Services, reporting to the Director of Technology & Architecture. This role owns and drives end-to-end IoT system architecture, spanning physical sensors, devices, connectivity, edge platforms, messaging infrastructure, cloud services, data pipelines, and fleet operations. This position requires hands on architectural depth across device side telemetry and edge communication, not just cloud or backend systems. The Senior IoT Architect ensures that Connected Services solutions are scalable, secure, reliable, observable, and cost-effective by designing coherent systems from sensor to cloud, accounting for real world fleet constraints. You will work closely with Technical Leads, firmware and edge teams, AI/ML, IT, Core Product Engineering, and Product Management to translate product and business needs into clear, executable system architectures and technical roadmaps. Requirements: • Define and own end-to-end IoT system architecture, from sensor data acquisition and device behavior through edge platforms, messaging, cloud services, analytics, and fleet operations. • Architect upstream IoT components, including sensor integration, edge data validation, telemetry transport, and device to cloud communication reliability. • Ensure device, edge, and cloud components integrate cleanly and operate as a coherent, production ready system. • Drive architectural decisions for device onboarding, secure provisioning, telemetry ingestion, command & control, OTA update strategies, and fleet lifecycle management. • Define connectivity strategies across BLE, WiFi, and Cellular, accounting for latency, bandwidth, cost, and reliability tradeoffs. • Design and govern MQTT based telemetry systems, including: Topic hierarchy and namespace design, QoS strategy and delivery guarantees, retained messages and offline device handling, and Secure communication using certificates, identity, and encryption
