Job Description We are looking for a Senior QA Engineer / SDET to drive quality across our AI-native backend services and platform systems. You will own test automation strategy, release quality gates, and quality engineering practices — working closely with backend engineers (Java + Python), product managers, and platform architects. This role focuses heavily on validating hexagonal architecture adapters, Kafka event pipelines, multi-database correctness, and AI scoring model outputs. Key Responsibilities • Design, build, and scale automated test frameworks for Java microservices built on hexagonal architecture — with distinct test strategies for the domain core, adapter layers (MongoDB, PostgreSQL, Cosmos DB, Kafka, Elasticsearch, Redis/Aerospike), and external integrations. • Develop and maintain comprehensive test suites: functional, integration (Testcontainers), regression, contract, and end-to-end across all adapter implementations. • Validate Kafka event pipelines: consumer behavior, event ordering, idempotency, poison pill handling, and dead-letter queue processing. • Validate MongoDB document integrity, PostgreSQL relational consistency, Cosmos DB partition correctness, and Elasticsearch index accuracy across service boundaries. • Design and execute golden dataset test scenarios — seeding realistic dealer and customer data to validate scoring accuracy, suppression correctness, and attribution logic. • Validate Python-based AI/ML service outputs: scoring model results, recommendation correctness, and LLM response safety gates. • Collaborate closely with backend engineers and architects to embed quality early in hexagonal domain design and adapter implementation. • Drive testability improvements by influencing API design, logging, observability, and error handling. • Own release quality and go/no-go decisions by defining and tracking quality gates in CI/CD pipelines. • Define and monitor quality metrics: test coverage, defect leakage, flakiness, MTTR, and automation ROI. • Lead root cause analysis for production issues and drive preventive measures. • Mentor junior QA/SDET engineers and set best practices across teams. Skills & Experience • 6+ years of hands-on experience in QA Engineering, Test Automation, or SDET roles. • Strong test automation expertise using modern Java-based frameworks; working knowledge of Python test frameworks (pytest) is a strong plus. • Deep experience testing distributed microservices, REST APIs, and Kafka-based architectures. • Experience with Testcontainers for integration testing across MongoDB, PostgreSQL, Kafka, and Elasticsearch locally. • Strong understanding of Kafka testing: consumer behavior, event ordering guarantees, and idempotency validation. • Experience with MongoDB and PostgreSQL testing patterns: data integrity, schema migration validation, multi-tenant isolation verification. • Familiarity with Elasticsearch test strategies: index correctness, relevance, and query result validation. • Experience with CI/CD pipeline integration (GitHub Actions, Jenkins, or equivalent). • Familiarity with containerized environments (Docker, Kubernetes). • Excellent problem-solving, communication, and collaboration skills. Preferred Skills • Experience validating AI/ML model outputs and scoring pipeline correctness. • Exposure to contract testing (Pact or similar) and service virtualization for hexagonal adapter boundaries. • Experience with performance, load, and chaos testing (JMeter, Gatling, k6) against Elasticsearch and Kafka. • Background in DevOps or Site Reliability Engineering practices. Perks & Benefits • Competitive compensation and generous stock options. • Medical insurance coverage. • Work with some of the brightest minds from Silicon Valley's most dominant and successful companies.
