As a Systems Engineer, you will support the technical planning, development, and integration of mission‑planning and systems‑engineering artifacts that advance program goals and operational outcomes. You will help shape requirements, architectures, interface definitions, and engineering products that ensure system capabilities are aligned, traceable, and technically sound across the broader system landscape. In this role, you will collaborate with cross‑functional teams, contribute to disciplined engineering processes, and ensure solutions remain consistent with program objectives and stakeholder priorities.

What you’ll do:

• Provide feedback and refinement for mission‑level specifications in coordination with the system integrator and engineering teams.
• Support development of requirements, architectures, use cases, technical analyses, interface definitions, and system‑level roadmaps.
• Define component‑level requirements derived from operational needs, system behaviors, and stakeholder priorities.
• Lead or support generation and implementation of Interface Control Documents (ICDs).
• Contribute to the creation of requirement‑verification artifacts for mission‑planning and component specifications.
• Work with data, AI/ML, software, and systems‑engineering teams to integrate required data sources, model inputs, outputs, assumptions, and validation methods.
• Identify technical risks, dependencies, integration challenges, sequencing concerns, and capability gaps across system‑engineering activities.
• Ensure systems‑engineering efforts remain aligned with program objectives, MBSE practices, CTO advanced analytics initiatives, and stakeholder needs.
• Support engineering activities related to ground systems and Agile‑based development workflows.

Required Qualifications:

• Associates degree and 10+ years of experience in a Systems Engineering related field; OR bachelor’s degree in Computer Science, Computer Engineering, Cloud Computing, or related field and 8+ years of experience in a Systems Engineering related field; OR a master's degree in Computer Science, Computer Engineering, Cloud Computing, or related field and 6+ years of experience in a systems engineering related field; OR a Ph.D. and 3+ years of experience. Additional four (4) years of relevant experience will be considered in lieu of a degree.
• This position requires the candidate possess a minimum of Secret clearance with ability to upgrade to TS/SCI. The candidate must maintain the clearance.
• Experience contributing to systems‑engineering activities such as requirements development, architecture definition, interface analysis, or verification support.
• Demonstrated experience developing and interpreting Interface Control Documents (ICDs) and supporting interface integration across system components.
• Proven ability to analyze system behaviors, data dependencies, and integration needs in support of mission‑planning and component‑level design.
• Experience collaborating with software, data, AI/ML, MBSE, and test teams to support integration of technical inputs, outputs, assumptions, and validation methods.
• Ability to identify and communicate technical risks, dependencies, and integration challenges within multi‑component system environments.

Desired Qualifications:

• Familiarity with Model‑Based Systems Engineering tools or practices.
