About the Role

We are seeking a Staff SDET to own the quality architecture for our AI-native platform. This is a quality engineering leadership role focused on designing and implementing test strategies across all layers of the hexagonal architecture.

Key Responsibilities

→Own the complete quality architecture: define test strategies at each hexagonal layer — domain core unit tests, adapter integration tests (Testcontainers), service-to-service contract tests (Pact), and end-to-end scenario tests.
→Design and build the golden dataset evaluation framework: seed realistic multi-tenant dealer/customer data across MongoDB, PostgreSQL, Cosmos DB, Elasticsearch, and Kafka, and define assertion criteria for scoring accuracy, suppression correctness, and attribution logic.
→Establish AI quality gates: define evaluation criteria for ML model outputs (scoring, recommendations), LLM response quality, RAG retrieval accuracy (precision@k, recall), and agentic workflow correctness.
→Architect test infrastructure: Testcontainers configurations for MongoDB, PostgreSQL, Cosmos DB, Kafka, Elasticsearch, and Redis/Aerospike — enabling fully local integration test runs.
→Own CI/CD quality pipeline: define what automated tests run at commit, PR, staging, and pre-release gates — with blocking quality thresholds.
→Define and track quality metrics: test coverage per hexagonal layer, defect leakage, flakiness rate, MTTR, and automation ROI.
→Lead root cause analysis for production escapes — own post-mortems and preventive measure implementation.
→Mentor Senior SDETs and QA engineers across both teams; conduct design reviews for test frameworks and golden dataset designs.
→Influence backend and frontend engineers on testability: drive API design, logging, observability, and error handling that makes services intrinsically testable.

Requirements

✓8+ years of QA Engineering, Test Automation, or SDET experience with strong hands-on engineering depth.
✓Deep expertise designing test strategies for hexagonal architecture: proven ability to test domain cores independently from adapters, and adapters independently from each other.
✓Strong programming skills in Java (primary) and Python — able to write production-quality test frameworks, not just test scripts.
✓Expert-level Testcontainers experience across MongoDB, PostgreSQL, Kafka, Elasticsearch, and Redis/Aerospike.
✓Experience with contract testing (Pact or similar) for service boundary validation and service virtualization.
✓Deep Kafka testing expertise: consumer group behavior, event ordering guarantees, idempotency, and dead-letter queue validation.
✓Experience designing golden dataset strategies: multi-tenant data seeding, realistic event sequences, and deterministic assertion design.
✓Experience integrating quality gates into CI/CD pipelines with meaningful blocking thresholds.
✓Strong understanding of AI/ML output validation: scoring correctness, RAG retrieval quality metrics, and agentic workflow eval design.
