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.

• →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.
