Job Description

Filevine is a Legal AI company delivering Legal Operating Intelligence for the future of legal work. Grounded in a singular system of truth, Filevine brings together data, documents, workflows, and teams into one unified platform—where modern legal work happens with clarity and consistency.   Powered by LOIS, the Legal Operating Intelligence System, Filevine connects context across every matter to transform legal operations from reactive to proactive. LOIS reads, understands, and reasons across your data to surface insight, automate complexity, and give professionals the clarity and confidence to see more, know more, and do more. Fueled by a team of exceptional collaborators and innovators, Filevine’s rapid growth has earned AI awards and recognition from Deloitte and Inc. as one of the most innovative and fastest-growing technology companies in the country.

Role Summary: Filevine's 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
