Looking for a QA Engineer quickly grasp the domain and drive both manual and automation testing across edge, controller, and cloud services to migrate a legacy IoT monolith into a microservices-based platform.
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.
- 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.
- Understanding and testing exposure with messaging protocols: MQTT and AMQP.
Prior IoT product testing experience is mandatory (devices, gateways, controllers, cloud).
