Senior Software Development Engineer in Test (SDET)
Team: Quality
Location: United States
Commitment: Full-time
Workplace Type: remote
Role Summary:
Filevines Telephony team builds the voice communication capabilities that keep our customers connected to the information and people who matter most to their concerns. The platform spans a range of surfaces, from deep backend services and integrations to customer-facing applications and intelligent, AI-driven voice experiences.
We are looking for a Senior SDET to own quality across this full breadth. The ideal engineer is equally at home driving rigorous backend and API testing, validating customer-facing applications, and inventing new approaches to test systems that resist conventional, UI-driven automation. This is a backend-leaning, tooling-heavy role for an engineer who wants to solve hard testing problems and raise the quality bar for the entire team, not simply execute existing test plans.
Responsibilities
-
Design and write test plans and automated test scripts across backend services, APIs, and customer-facing applications
-
Analyze and improve the scalability, performance, and efficiency of the testing pipeline
-
Design and implement automated test frameworks
-
Build solutions to aid in automated and load testing
-
Responsibly drive complex projects forward to completion
-
Exercise independent judgment
-
Make informed recommendations to management
-
Provide leadership and mentoring to other engineers
-
Independently identify opportunities for automated testing at different levels (End to End, Integration, UI, etc.) and possible solutions
-
Communicate frequently, clearly, and effectively with various technical and management audiences on usability, serviceability, and suggested changes
Qualifications:
-
7+ years working as a software engineer or test automation engineer
-
Expert in an object oriented language such as C# or Java
-
Complete understanding of the application development life cycle
-
Expert knowledge of QA testing techniques and the STLC
-
Expert experience testing REST web services
-
Expert at testing backend-heavy services where little or no user interface is available to drive testing
-
Demonstrated ability to design and build custom test tooling and harnesses for systems that are difficult to exercise through conventional automation, including asynchronous and event-driven services
-
Practical experience applying GenAI/LLMs to solve engineering productivity, test generation, and analysis challenges
-
Experience with stress and load testing tools and techniques
Nice to Have:
-
Experience testing telephony, VoIP, or other real-time communication systems
-
Experience testing AI-driven, conversational, or agent-based applications
-
Familiarity with modern front-end frameworks
-
Expert understanding of advanced techniques such as stubbing and mocking
-
Expert understanding of source control systems (GitLab) and CI/CD pipelines
-
Expert understanding of automated testing frameworks such as Playwright
