Arcfield•Chantilly, VA

About The Position

Arcfield is seeking an experienced Mission / Systems Engineer to support the development and integration of advanced space-based sensing and mission capabilities for the US Space Force and national security. The role is part of a multidisciplinary mission engineering team and supports senior technical leadership while owning mission- and requirements-focused engineering activities. The engineer will work with government customers, mission users, and technical stakeholders to understand operational needs, analyze information from technical and requirements sources, and contribute to mission concepts, CONOPS, requirements, architecture, and solution development. The position involves moving between operational and technical perspectives, identifying relationships and gaps in complex documentation, communicating technical findings, and translating ambiguous mission needs into actionable engineering problems. Work spans the system lifecycle, from mission concept and requirements development through development, integration, test, deployment, and operations.

Requirements

Bachelor of Science degree and 5–7 years of experience, Master of Science degree and 3–5 years of experience, or PhD and 0–2 years of experience.
Technical degree or relevant experience, including internships or early-career professional experience.
Must possess and be able to maintain a TS/SCI clearance with polygraph.
Strong written and verbal communication skills.
Self-directed, motivated, and willing to take initiative in an environment where requirements and priorities can evolve.
Ability to work effectively with technical leads, teammates, customers, and multidisciplinary engineering teams.

Nice To Haves

Experience or interest in systems engineering and mission engineering.
Knowledge of space systems, sensors, RF/radar, and satellite communications.
Familiarity with ground systems and mission processing.
Experience or interest in modeling and simulation, data analysis, and integration and test.
Familiarity with MATLAB, STK, MBSE tools, DOORS, Jira, or similar engineering tools.

Responsibilities

Support mission and systems engineering activities across the full system lifecycle, from mission concept and requirements development through development, integration, test, deployment, and operations.
Engage with government customers, mission users, and technical stakeholders to understand operational needs, mission objectives, priorities, constraints, and challenges.
Support and participate in user engagements, working groups, technical discussions, and stakeholder reviews; capture and communicate mission needs and engineering considerations.
Develop and refine mission concepts, CONOPS, requirements assessments, requirements, user engagement materials, briefings, and related engineering products.
Analyze requirements and technical documentation from multiple sources to identify commonality, overlap, gaps, inconsistencies, dependencies, and items requiring clarification.
Translate operational and mission needs into actionable systems engineering activities and support requirements development, decomposition, allocation, and traceability.
Support requirements and architecture assessments by identifying technical, operational, and mission-level implications.
Participate in technical reviews and help identify risks, issues, assumptions, dependencies, and areas requiring additional analysis.
Maintain awareness of related engineering efforts and identify opportunities for integration, reuse, and alignment across technical threads.
