About The Position

Virtru is seeking a Senior Software Engineer for its Delivery Engineering organization. The role builds custom integrations and policy enforcement points for customers, particularly those operating in classified and other sensitive environments. The engineer works directly with customer engineers to understand their systems, design and deliver software suited to those environments, and explain the software to customer security reviewers. Work is scoped against statements of work, tested with QA, and delivered into customer environments that Virtru does not operate, including disconnected environments. The engineer partners with deployment and forward deployed engineers, QA, product engineering, and Platform Engineering. They build on Virtru SDKs and APIs, report product gaps and defects, and turn repeat customer solutions into reusable templates, libraries, or tools. The role also contributes to engineering standards, design reviews, documentation, release practices, and the team's use of AI coding agents. It may require travel up to 25% of the time, and work in classified environments at least 25% of the time.

Requirements

Active TS/SCI U.S. security clearance.
Experience building and shipping production software, owning code from design through release and maintenance, and discussing the relevant language and stack in depth.
Ability to explain software designs and security properties to government security reviewers and respond to follow-up questions.
Willingness to work directly with customers in their environments on customer problems.

Nice To Haves

Production .NET experience on Windows, including Windows Services, signed installers, and managed distribution.
