System Engineer (Human Factors)

SciTec•Boulder, CO

13h•$156,000 - $193,000

About The Position

SciTec, a subsidiary of Firefly Aerospace, is seeking a Systems Engineer with a specialization in human factors and software user experience to support the Ground‑Based Radar Digitization (GBRD) modernization program. This role focuses on the systems engineering of operator-facing interfaces, ensuring mission users can clearly understand radar system state, data flow, alerts, and operational context. The engineer will translate mission and stakeholder needs into system requirements, define UI workflows, manage interface specifications, and guide the integration of display components into the modernized architecture. This position involves collaboration with radar-processing teams, MBSE modelers, UI/UX designers, backend developers, mission operators, and government stakeholders to deliver clear, actionable, and intuitive user displays. SciTec exclusively works on U.S. government contracts requiring U.S. citizenship, and cannot sponsor work visas. Applicants must meet these requirements.

Requirements

Bachelor’s or Master’s degree in Systems Engineering, Human‑Systems Integration, Electrical Engineering, Computer Engineering, or related field.
5+ years of experience in systems engineering for complex software systems, sensor/mission systems, or operator‑facing interfaces.
Experience writing and managing system and interface requirements for user interfaces or mission displays.
Familiarity with radar systems, real‑time data flows, alerting systems, or high‑bandwidth operational environments.
Experience with MBSE practices, SysML, or model‑based requirement traceability.
Ability to collaborate with UI/UX designers and software teams to translate mission needs into display functionality.
Understanding of operator workflows, human‑factors considerations, and mission‑focused interface design.
Strong communication skills for cross‑disciplinary collaboration.
U.S. Citizenship with ability to obtain and maintain a DoD security clearance (active preferred).

Nice To Haves

Active DoD security clearances.
Prior experience with operator interfaces for radar systems, air and missile defense systems, or space domain systems.
Experience with developing components in a system with an open systems architecture (e.g. Modular Open Systems Approach).
Experience supporting system integration events or mission‑scenario verification.
Experience modeling user workflows or UI architectures within a SysML or MBSE environment, particularly using the Cameo suite of tools.
Background in human‑systems integration, usability evaluation, or cognitive workflow analysis.

Responsibilities

Develop and communicate mission human factors requirements, capturing and refining stakeholder needs.
Develop system- and subsystem-level requirements for user interfaces, visualizations, alerting behavior, data-flow awareness, and operator workflows.
Define operational user interface concepts, display behaviors, and functional flows aligned with mission use cases and radar system behavior.
Develop architectures and system-to-system interfaces for user-facing components, defining data flows and ensuring alignment with site space and power requirements.
Ensure user interfaces meet mission-assurance, cybersecurity, accessibility, and reliability standards for DoD environments.
Support the creation of a digital engineering baseline using SysML to develop key engineering artifacts and maintain traceability.
Maintain configuration control of display-system requirements, diagrams, and ICDs.
Support program integration, verification, and test activities, including system integration testing, mission-scenario validation, and user-workflow assessments.
Evaluate display responsiveness, clarity, and operator usability during integration events.
Support program requirements verification activities.
Collaborate with radar and signal processing engineers, system architects, UI/UX designers, backend developers, operators, and IV&T teams to ensure cohesive system behavior.
