About The Position

We are seeking a Mid to Senior SDET to own and evolve our test infrastructure, enabling our engineering team to ship quality features at velocity. You will design test harnesses, establish testing best practices, and ensure our platform—including AI Agent capabilities—is thoroughly validated across API, backend, and full-stack scenarios. This is not a QA role. You are an engineer with a testing focus, embedded with developers, contributing to sprint work, test strategy, and platform reliability.

Requirements

5+ years total software engineering experience with 3+ years focused on test automation/SDET work
A deep understanding of automation testing and ability to lead engineers in writing automation scripts/programs that aid automated testing
Strong proficiency in at least one backend language: Java, Node.js with object-oriented design experience
API testing expertise: REST, request/response validation, mocking, contract testing.
Test framework experience: JUnit, Jest, or equivalent; experience building custom frameworks a plus
Tools and Test Platforms - SOAPUI, Postman, Bruno, Playwright, Selenium, Cucumber, Hammer and Cyara.
Voice and Chat test automation expertise and familiarity with test methodologies for conversational systems.
CI/CD pipeline knowledge: GitHub Actions, comfortable with automation in pipelines
Test data management: Experience designing and maintaining test data strategies
Full-stack testing: Comfortable testing across APIs, backends, and frontend layers
Strong communication: Ability to document patterns, mentor others, and articulate testing strategy
Familiarity with software technologies, methodologies, and applied software engineering practices such as Object-Oriented Design (OOD) and cloud software development
Experience with testing LLM/AI responses, using such approaches as LLM-as-a-judge, etc

Nice To Haves

Deep hands-on technical expertise in automation, developing test frameworks, tools, and APIs
