Senior Test Infrastructure Engineer

SciTec•Boulder, CO

About The Position

SciTec, a wholly owned subsidiary of Firefly Aerospace, is a dynamic non-traditional defense contractor that delivers advanced technologies in support of U.S. National Security and Defense. For the past forty-five plus years, we have supported Department of Defense customers by developing innovative remote sensing algorithms, tools, and techniques to deliver world-class data exploitation capabilities supporting missile defense; intelligence, surveillance, & reconnaissance; space domain awareness; and aircraft survivability missions. Important Notice: SciTec exclusively works on U.S. government contracts that require U.S. citizenship for all employees. Applicants that do not meet this requirement will not be considered. We are seeking a Senior Test Infrastructure Engineer to design, build, and operate the infrastructure, environments, and tooling that enable effective testing across complex software and infrastructure systems. This role focuses on test environments, system integration scaffolding, automation platforms, and CI/CD-integrated test infrastructure, rather than writing application test cases. The ideal candidate is a strong infrastructure or platform engineer with a testing mindset—someone who enables teams to test reliably, repeatedly, and at scale.
