You’ll work closely with systems engineers, software developers, and program stakeholders to define system-level architecture, ensure interoperability, and guide the technical direction across multiple domains including space, cyber, and digital modernization.

Key Responsibilities:

• Develop, maintain, and communicate system and enterprise architectures for mission-critical systems.

• Translate operational requirements and CONOPS into technical architectures and design solutions.

• Lead architecture definition, design reviews, and trade studies to guide technical decisions.

• Create and manage architecture artifacts including system views, interface control documents (ICDs), and data exchange specifications.

• Ensure compliance with DoDAF, UAF, or enterprise architecture frameworks, as required by the customer.

• Define system integration and interoperability strategies across hardware, software, and cloud environments.

• Support Model-Based Systems Engineering (MBSE) efforts using tools such as Cameo, MagicDraw, or Sparx Enterprise Architect.

• Collaborate with cybersecurity engineers to ensure architecture resilience and compliance with mission security requirements.

• Evaluate emerging technologies and recommend architectural enhancements to improve system performance, scalability, and maintainability.

• Support program reviews, milestone readiness, and risk assessments for architecture implementation and verification.

Required Qualifications:

• Bachelor's degree in Systems Engineering, Computer Science, Electrical Engineering, or related technical discipline.

• Active TS/SCI clearance (polygraph may be required for specific programs).

• 8+ years of experience in systems engineering or architecture for government, defense, or intelligence systems.

• Strong knowledge of systems engineering lifecycle processes, including requirements, design, integration, verification, and validation.

• Demonstrated expertise in architecture modeling, interface management, and technical baseline control.

• Experience using MBSE tools and techniques to support architecture development.

• Excellent written and verbal communication skills, including the ability to brief senior leaders.

Desired / Preferred Qualifications:

• Master's degree in Systems Engineering or related technical field.

• INCOSE CSEP, DoDAF, or MBSE certification.

• Experience with cloud architectures, hybrid computing, or enterprise service integration (e.g., AWS, Azure, Kubernetes).

• Knowledge of space systems, ground control, or C4ISR architectures.

• Familiarity with Agile and DevSecOps environments and how they interface with system architecture processes.

• Experience with digital engineering and digital twin environments.

• Understanding of mission assurance and cybersecurity architecture principles.

Why Join Arcfield:

• Work on mission-critical programs that safeguard U.S. and allied national security.

• Collaborate with top-tier engineers and architects in a cleared, high-impact environment.
