## Description

We are seeking a Mid to Senior Software Development Engineer in Test (SDET) to join a team developing a Conversational AI platform that delivers voice and chat experiences. The ideal candidate will own and evolve test automation frameworks, helping ensure quality, reliability, and scalability across the platform., This is not a traditional QA role. As an engineering-focused SDET, you will partner closely with software developers to build automated testing solutions, define testing strategies, and validate platform capabilities across APIs, backend systems, user interfaces, and AI-enabled features. You will contribute directly to sprint deliverables while helping drive engineering excellence and platform reliability.

_*Please note, this role is not able to offer visa transfer or sponsorship now or in the future*_

In this role, you will:

 - Understand how all elements of the system software ecosystem work together and develop QA approaches and tools that fit the overall strategy

 - Collaborate with Product, Architecture, and Engineering teams to define test strategy, coverage goals, and acceptance criteria

 - Develop test strategies and create appropriate test harnesses for Conversational AI systems across Voice and Chat channels

 - Identify testing gaps and recommend solutions

 - Design, build, and maintain reusable test harnesses and frameworks that eliminate decision paralysis for engineers

 - Provide clear patterns for: test framework selection, test data setup, and test implementation

 - Create comprehensive examples and documentation so developers can write tests without reinventing solutions

 - Provide test infrastructure to enable engineering teams to test and own quality of the services

 - Support testing across Java/Node.js backends, APIs, and Conversational AI platforms

 - Develop specialized test strategies for conversational AI workflows and agent interactions

 - Build test harnesses for API-level, backend service, and end-to-end scenarios

 - Validate complex multi-turn conversations, intent recognition, and orchestration logic

 - Develop and automate Voice and Chat test plans

 - Be a stakeholder of the release to ensure defects are fixed per SLA and end customer experience is protected and improved

 - Monitor and report on test execution and quality metrics

 - Validate that platform changes maintain or improve customer experience

 - Educate and train engineers on test harnesses, frameworks, and best practices

 - Mentor team members on test-driven development and automation patterns

 - Make testing accessible-remove friction from the testing process

 - When harness work is complete, contribute to automated test implementation and general development items
