Description

At UNCOMN, we don’t just fix issues; we deliver secure solutions that power essential operations in both the public and private sectors. Our team tackles tough challenges—whether it’s improving organizational systems, streamlining logistics, or making sense of complex data—all with one goal: helping our clients succeed so they can continue serving others.  

We’ve built a culture rooted in our Core Values, where innovation thrives, work-life balance is respected, and career growth is always encouraged. We're also proud to be recognized as a ‘Top Workplace,’ and that’s not just us talking; it’s our employees. Now, we’re looking for another Uncommon Genius to join our dynamic team. If you love solving puzzles, building new things, fixing what’s broken, or pushing the boundaries of creativity, we encourage you to explore the details of this position below! 

UNCOMN is seeking a Senior Systems Engineer/Enterprise Architect to:

• Support system architecture design, requirements development, integration planning, and configuration management activities.
• Provide engineering expertise for mission systems across the full lifecycle from concept development through deployment, operations, and sustainment.
• Develop and maintain system architecture artifacts using UAF and DoDAF, including operational, system, service, and capability viewpoints as appropriate.
• Utilize Model-Based Systems Engineering methods.
• Collaborate with customer and contractor teams to ensure interoperability, scalability, and mission alignment across systems and interfaces.
• Conduct analysis of system performance, dependencies, and risks; provide clear, actionable recommendations for optimization.
• Evaluate and recommend tools, techniques, and processes to improve system development, integration, and lifecycle management.
• Develop and maintain high-quality technical documentation, including Interface Control Documents (ICDs), system descriptions, engineering reports, and architecture decision artifacts.
• Ensure engineering artifacts align with configuration management practices and government standards.
• Serve as a professional, credible, and approachable technical representative in client-facing environments.
• Communicate complex technical concepts clearly and confidently to both technical and non-technical stakeholders.
• Influence architectural and engineering decisions through collaboration, trust-building, and well-reasoned analysis rather than positional authority.
• Support alignment across multiple teams, helping reduce friction and improve shared understanding during transformation initiatives.

This position description outlines the core duties for this role, but it is not all-inclusive. Responsibilities may shift based on contract requirements, mission needs, or organizational objectives.

• Strong understanding of systems engineering principles.
• Demonstrated experience working in a DoD or Intelligence Community (IC) environment.
• Hands-on experience developing architecture views, conforming to DoDAF or UAF standards, and developing architectures to ISO/IEC/IEEE 15288 System Life Cycle concepts and practices.
• Experience with Model-Based Systems Engineering (MBSE) tools and methodologies, preferably Sparx EA and/or Cameo EA, particularly for architecture modeling, traceability, and requirements integration.
• Excellent written and verbal communication skills, with the ability to engage effectively with senior government stakeholders.
• Must be comfortable working onsite with the potential to travel (estimated) once per month.

Preferred

• Active DoD (top) secret clearance.
