Job Description
Senior QA Engineer
Weekday (YC W21)
• The QA engineer is responsible for the test strategy spanning both services, which includes reviewing unit tests, conducting integration testing, validating AVRO contracts, and coordinating UAT with the client.
Job Requirements
- Min Experience: 5+ years
- Test strategy & planning: Capable of developing a multi-layered testing approach (unit, integration, contract, acceptance) specifically for data integration services; experienced in drafting acceptance criteria for batch/ETL-style processes.
- Contract testing (AVRO): Skilled in validating message schemas with a Schema Registry, assessing backward and forward compatibility, and ensuring that generated events conform to the established contract.
- Integration testing: Practical experience in testing **API-to-Kafka pipelines**, including setting up mock or sandbox environments for third-party APIs, validating Kafka consumers, and confirming end-to-end data flow integrity.
- Test automation: Proficient in creating automated tests using tools such as pytest, Jest, or equivalents that integrate seamlessly into CI/CD pipelines; knowledgeable in using test fixtures for DynamoDB, Kafka, and REST API stubs.
- Data validation: Skilled at ensuring data accuracy at every pipeline stage — from the source API response, through DynamoDB intermediate states, Kafka event payloads, to the Snowflake destination when accessible.
- UAT coordination: Experienced in assisting business stakeholders during user acceptance testing by managing defect triage, preparing test evidence, and facilitating staging sign-offs.
- Knowledge of Kafka testing tools, for example kafka-console-consumer, schema registry CLI, and Confluent test utilities.
- Experience executing and analyzing performance and soak tests for batch workloads.
- Understanding of idempotency testing to ensure that repeated executions do not result in duplicate events.
