Job Description

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.
