Own platform-level technical decisions for distributed cloud components and microservices using C#, .NET Core, MVVM, and related frameworks, applying object-oriented design and SOLID principles. Lead and mentor the development team, overseeing project execution, code quality, and technical delivery. Design, develop, and optimize real-time data pipelines between IoT devices, gateways, and cloud platforms using MQTT, WebSocket, SignalR, Redis, TCP/IP, and Kafka, leveraging Rust where performance and concurrency optimization are critical. Define and implement REST APIs and microservice architectures for large-scale IoT deployments, ensuring high availability, performance, and maintainability. Oversee cloud infrastructure deployment and operations (AWS or equivalent), including EC2, Lambda, Route 53, Cognito, RDS, ELB, and CloudWatch, to ensure fault tolerance, scalability, and reliability. Design and manage LoRaWAN networks, LNS systems, and the network and communication layers for other IoT protocols, including device provisioning, messaging, and network optimization. Design and implement scalable, high-performance data systems using MySQL and exposure to Cassandra or equivalent databases for telemetry and analytics workloads. Drive technical strategy for web interfaces and dashboards, enabling device management, configuration, and real-time visualization. Lead IoT security efforts, including secure coding practices, and coordinate with the security team on penetration testing, vulnerability scanning, and remediation. Ensure platform compliance with ISO 9001 standards and implement ISO-compliant software development processes. Collaborate cross-functionally with embedded, DevOps, security, product management, business, and customer teams to define platform architecture, device-cloud integration strategies, and roadmap priorities. Provide senior-level technical guidance and Level 3 support for production IoT systems, resolving complex issues affecting cloud platforms and device networks. Develop and execute automated unit and integration tests (e.g., NUnit) to ensure code quality, reliability, and adherence to ISO-compliant development processes. Document platform architecture, operational procedures, and design decisions to support internal knowledge, regulatory compliance, and continuous improvement. Participate in Agile planning and governance, influencing process improvements, technical strategy, and prioritization of work to ensure timely project delivery.
