About this role

SciTec, a Firefly Aerospace company 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 Principal Software Engineer to serve as our Data Storage Domain Lead. In this role, you will guide how our engineering teams select, design, implement, optimize, and operate data persistence and retrieval systems that support mission critical data processing, visualization, and operational workflows.

This role is hands on and combines deep technical work with technical stewardship: you will assess how our teams use storage technologies today, establish evidence-based recommendations, build reference implementations, and work directly with engineers to raise our organization-wide capability. The ideal candidate has deep, production-grade expertise in data storage systems, the ability to evaluate technical alternatives against real workload requirements, and the communication and mentoring skills to turn that expertise into practical guidance that other engineers can adopt independently.

Responsibilities Assess current storage technologies, data access patterns, recurring problems, and capability gaps across engineering teams. Define evaluation criteria and use benchmarks against representative workloads to select and maintain a Core Collection of recommended storage technologies, patterns, and practices. Document recommended technologies, valid alternatives, and exceptional cases through decision guides, reference architectures, architecture decision records (ADRs), and tuning and troubleshooting guides.
