Systems Engineer - Compute and Software Systems

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., SciTec is seeking a Systems Engineer with experience in software-defined sensor data processing pipelines and supporting computaional systems to support the Ground-Based Radar Digitization (GBRD) modernization program. This engineer will be responsible for use case development, requirements definition, architecture development, and verification support for a modernized, software-centric radar data processing backend system., * Requirements Development & Traceability - Derive, refine, and manage system-level and subsystem-level requirements for software processing flows including data ingest, timing/synchronization, signal processing outputs, interfaces. Define requirements constraining the system design, including latency, throughput, cybersecurity requirements, and space/weight/power constraints. Maintain full traceability of requirements within a digital engineering environment.

• Systems Architecture & Interface Definition - Develop a high-level software architecture for deploying signal processing services within a Kubernetes-based environment. Support the design of computing infrastructure which can execute the designed software architecture. Ensure that the resulting system is modular, open, interoperable, and addresses cybersecurity requirements.
• Model-Based Systems Engineering (MBSE) - Create and maintain MBSE artifacts (SysML diagrams, functional flows, ICDs represented as digital models) that describe system behavior, support design decisions, and drive verification planning.
• Integration & Verification Planning - Define integration strategies for software-processing components. Support system-in-the-loop testbed planning, verification event preparation, and validation of processing chains against mission needs.
• Cross-Team Coordination - Collaborate with radar-frontend teams, signal processing algorithm developers, cybersecurity, mission operations stakeholders, MBSE validators, and government technical directors to ensure system alignment, risk reduction, and requirement compliance.
• Risk Management & Configuration Control - Identify and track technical risks for the processing architecture and supporting computing infrastructure. Support configuration management processes within the centralized digital repository.
• Support Technical Communication - Develop artifacts and communicate effectively in support of external program reviews and internal design meetings.

• Bachelor’s or Master’s degree in Systems Engineering, Electrical Engineering, Physics, Computer Engineering, or related technical field.
• 5+ years of experience in systems engineering for sensor systems, large-scale real-time systems, or mission-critical software-processing pipelines.
• Experience developing or maintaining system architectures, requirements, and interface specifications for data-processing systems.
• Familiarity with the design and architecture of high-throughput sensor data processing systems.
• Familiarity with model-based systems engineering tools and techniques.
• Strong technical communications skills for cross-functional collaboration
• U.S. Citizenship with ability to obtain and maintain a DoD clearance.

Candidates meeting the following criteria will be preferred:

• Experience with radar-processing architectures.
• Experience in developing modular and open systems architectures.
• Experience with Kubernetes or high-performance computing environments.
• Experience supporting software-in-the-loop or hardware-in-the-loop integration environments.
• Familiarity with digital twin approaches or large-scale MBSE repositories.
• Familiarity with DoD cybersecurity (NIST 800-53) and program protection processes.
• Active DoD security clearance.

*Resumes, Cover Letters, and Applications which are generated by AI will not be considered for employment.
