Senior IoT QA Engineer (Pune / Hyderabad)

We're modernizing a legacy IoT monolith into a microservices-based platform. Seeking a hands-on QA engineer who can quickly grasp the domain and drive both manual and automation testing across edge, controller, and cloud services.

Responsibilities

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

• Own end-to-end test strategy for legacy and new microservices, covering API and messaging workflows.

• Design, write, and maintain automation test suites in Python for REST, SOAP, gRPC and messaging protocols.

• Prepare and execute detailed test plans and test cases, ensuring full coverage across device, gateway, and cloud components.

• Validate device messaging flows including telemetry, commands, events, c2d/d2c communication, twin updates, and partner integrations.

• Ensure backward compatibility between legacy SOAP services and new REST/gRPC services throughout migration.

• Track defects, ensure root cause clarity, and partner with engineering to tighten quality gates.

• Contribute to CI integration and continuous improvement of automation frameworks and processes.

Must-Have Requirements

• 6+ years of QA experience with strong hands-on automation using Python.

• Strong verbal and written communication; clear neutral accent for global collaboration.

• Solid experience testing APIs across REST, SOAP, and gRPC.

• Strong understanding and testing exposure with messaging protocols: MQTT and AMQP.

• Prior IoT product testing experience is mandatory (devices, gateways, controllers, cloud).

• Experience in both automation and manual testing, with strong test case design and execution skills.

• Proven experience testing distributed systems, microservices, and containerized environments.

Good to Have

• Experience with serial or USB-based device testing.

• Experience with event-driven architectures, schema validation, and performance testing for IoT systems.
