Sr SDET Data & Platform Quality
Location: Dallas, TX (Hybrid 3 days per week in-office)
Interview Process: In-Person Interview
Locals & Non-Locals Can apply.

Role Overview
We are seeking a Senior SDET to own automation quality for large-scale, data-heavy, event-driven platforms. This role focuses on backend, Kafka, and AWS data platform validation using Python-based automation frameworks.

This is a hands-on engineering role, not a traditional QA position.

No manual testing
No UI / Selenium-only testing
No basic ETL script validation

You will design and own automation frameworks that validate Kafka-driven architectures, backend services, and cloud-native data pipelines, while partnering closely with data and platform engineers.

Key Responsibilities
Automation & Framework Ownership
Design, build, and maintain Python-based test automation frameworks, not just individual test cases
Define reusable test libraries for validating data platforms and distributed systems
Drive automation standards, patterns, and best practices across teams

Kafka & Event-Driven Systems Testing
Validate Kafka-based event streams, including:
Topic-level data validation
Producer and consumer behavior
Message schemas, payload integrity, ordering, and replay scenarios
Failure handling, retries, and dead-letter scenarios
Test asynchronous workflows and event propagation across services

Data Platform & Backend Validation
Validate end-to-end data flows across distributed services and pipelines
Test backend APIs, service integrations, and asynchronous processing layers
Perform schema validation, transformation checks, data consistency, and completeness validation

AWS & Cloud Data Testing
Test cloud-native data platforms built on AWS services such as:
S3, Glue, Redshift, Lambda (or similar services)
Validate ingestion, processing, storage, and downstream consumption of data
Debug data and automation failures across multiple cloud services

CI/CD & Quality Gates
Embed automation into CI/CD pipelines
Enforce quality gates and fail pipelines on critical data or platform issues
Provide actionable feedback to engineering teams based on automation results

Collaboration & Strategy
Work closely with data engineers, platform engineers, and architects
Define test strategies for event-driven and distributed data systems
Proactively identify quality risks and gaps in platform design

Required Experience (Non-Negotiable)
Strong test automation engineering experience using Python
Hands-on Kafka testing experience (real production systems, not theoretical knowledge)
Proven experience testing distributed and event-driven systems
Solid understanding of data validation concepts, including:
Schemas and contracts
Transformations and enrichment
Data consistency, completeness, and accuracy
Experience working in AWS-based data platforms
Ability to debug and troubleshoot issues across multiple services, not just log defects
Engineering mindset with ownership mentality

Nice to Have
Experience with schema registries (Avro / JSON / Protobuf)
Knowledge of streaming vs batch data architectures
Familiarity with observability, logging, and monitoring in distributed systems
Experience working in high-volume, near-real-time data environments

Flexible work from home options available.
