Employment Type: Full-Time

About the Role

We are modernizing a large-scale legacy IoT monolith into a cloud-native, microservices-based platform on Microsoft Azure . We are looking for a hands-on Senior IoT Full Stack Engineer who can take ownership of development across cloud and edge services , with deep expertise in Azure IoT, distributed systems, and microservices architecture .

This role focuses on IoT cloud platforms, edge workloads, and backend services not on device hardware or firmware development. You will play a critical role in designing, building, and scaling a next-generation IoT platform that supports reliable, secure, and high-volume data flows from edge to cloud.

Key Responsibilities

Platform Modernization & Development

• Ramp up quickly on the existing IoT platform, business domain, and modernization roadmap.
• Design, develop, and maintain cloud and edge microservices using .NET / C# , gRPC , and RESTful APIs .
• Break down monolithic components into independently deployable microservices.

Azure IoT & Edge Engineering

• Develop, deploy, and manage workloads on Azure IoT Edge and Azure Kubernetes Service (AKS) .
• Build and integrate services across Azure IoT Hub, Event Hub, Edge Modules, Gateways , and cloud backend services.
• Implement edge-to-cloud communication patterns , including routing, buffering, offline sync, and failover handling.

IoT Data & Digital Twins

• Define and implement DTDL models for device capabilities, telemetry, and Azure Digital Twins .
• Own end-to-end data flows:
• Device Edge Gateway Cloud External Integrations .
• Ensure accurate modeling, ingestion, transformation, and consumption of IoT data at scale.

Messaging, Security & Reliability

• Implement reliable, secure messaging using AMQP and MQTT protocols.
• Ensure secure service-to-service communication using certificates, identities, and access controls.
• Design for resiliency, scalability, and fault tolerance in distributed IoT systems.

Collaboration & Delivery

• Collaborate closely with architects, QA, DevOps, and product teams to drive modernization milestones.
• Participate in architecture discussions, code reviews, and technical design sessions.
• Contribute to CI/CD pipelines, test automation, performance tuning, and observability improvements.

Must-Have Requirements

Core Engineering Skills

• 6+ years of professional software engineering experience.
• Strong hands-on expertise in .NET / C# development.
• Proven experience building gRPC-based microservices and RESTful APIs .

Azure & IoT Expertise

• Strong hands-on experience with Azure IoT services , including:
• Azure IoT Hub
• Azure IoT Edge
• Azure Event Hub
• Experience deploying and operating workloads on AKS or Kubernetes .
• Deep understanding of IoT messaging protocols : AMQP and MQTT .

IoT Architecture & Data Modeling

• Experience designing and implementing Edge + Cloud IoT architectures (gateway patterns, routing, buffering, offline sync).
• Strong understanding of DTDL , digital twin concepts , and IoT data modeling.
• Experience handling high-volume telemetry and event-driven data pipelines.

Good to Have / Nice to Have

• Experience with API Gateway patterns , service mesh , or distributed tracing .
• Exposure to Azure Functions , Cosmos DB , or Azure Time Series Insights .
• Experience building and managing CI/CD pipelines for IoT or microservices-based platforms.
• Familiarity with monitoring, logging, and observability tools in cloud-native environments.

Soft Skills

• Strong analytical and problem-solving skills.
• Excellent communication and collaboration abilities.
• Ability to work independently and take ownership of complex systems.
• Comfortable working in fast-paced, evolving engineering environments.
