Senior SDET Engineer

Role:Senior SDET Engineer(4-7 Years)

Location:Chennai

About Tekion:

Tekion is building the first cloud-native platform for the automotive retail industry. Our platform brings together dealer operations, digital retail, OEM integrations, and data intelligence to transform how dealers and OEMs operate at scale.

Role Overview:

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 & Qualifications:

• 4+ 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

Good to Have:

• 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.
