Senior IoT Full Stack Engineer (Pune / Hyderabad)

We're rebuilding a legacy IoT monolith into a modern microservices-based platform on Azure. Looking for a hands-on IoT engineer who can own development across cloud and edge services. This role focuses on Azure IoT, microservices, and edge workloads - not device hardware/firmware.

Responsibilities

• Ramp up quickly on current IoT platform, domain, and modernization roadmap.

• Design and build cloud and edge microservices using .NET/C# with gRPC and RESTful APIs.

• Develop, deploy, and manage workloads on Azure IoT Edge and AKS.

• Build integrations across Azure IoT Hub, Event Hub, Edge Modules, Gateways, and cloud back-end services.

• Implement DTDL models for device capabilities, telemetry, and digital twins.

• Own E2E development for data flows: device → edge → gateway → cloud → external integrations.

• Ensure reliable and secure messaging across IoT protocols (AMQP, MQTT) and service communication.

• Collaborate closely with architects, QA, and product to drive modernization milestones.

• Contribute to CI/CD, code quality, automation, and performance improvements.

Must-Have Requirements

• 6+ years of software engineering experience with strong .NET and C#.

• Solid experience building gRPC microservices and RESTful APIs.

• Strong hands-on Azure IoT skills: IoT Hub, IoT Edge, Event Hub, and related services.

• Experience with AKS or Kubernetes-based deployments for IoT or distributed systems.

• Strong understanding of IoT messaging protocols AMQP and MQTT.

• Experience designing and integrating Edge + Cloud solutions (gateway patterns, routing, offline sync, failover).

• Good hold on DTDL, digital twin concepts, and IoT data modeling.

Good to Have

• Experience with API Gateway patterns, service mesh, or distributed tracing.

• Exposure to Azure Functions, Cosmos DB, or Time Series Insights.

• Experience with CI/CD pipelines for IoT or microservices workloads.
