Cyber Architect and Integration Lead (SDIN)

Stellar Solutions Inc•Colorado Springs, CO

17h•$135,000 - $175,000•Hybrid

About The Position

Stellar Solutions is seeking a Cyber Architect and Integration Lead to support the U.S. Space Force in advancing secure, resilient, and interoperable network capabilities across the national security space enterprise. The position supports coordination between the SDIN and meshONE-T network environments and combines systems security engineering, classified network architecture, and enterprise integration. The successful candidate will help mission partners evaluate network solutions, establish secure interconnections, and navigate cybersecurity risk and authorization boundaries. This is an advisory and systems integration leadership role, rather than a hands-on network equipment configuration or installation position. The role works with government stakeholders, program leadership, network engineering teams, and mission partners to assess architectures and integration approaches, guide decisions, and communicate technical, cybersecurity, cost, schedule, and operational considerations. Work products may include architecture assessments, interconnection recommendations, cybersecurity compliance analyses, RMF package support documentation, onboarding guidance, cost-benefit evaluations, and executive briefings. The position is based in Colorado Springs, Colorado, and is hybrid, with regular on-site support at designated customer or program locations. Remote work may be permitted under the approved hybrid arrangement, with expectations determined by customer and program requirements. An active Secret security clearance is required.

Requirements

Bachelor's degree and at least 7 years of experience in network engineering or network architecture.
Technical experience with SDIN network capabilities and architecture.
CISSP or equivalent.
Demonstrated experience developing RMF packages supporting ATO, ATC, or ATT for classified or National Security Systems (CNSSI 1253), including body of evidence preparation and continuous monitoring (ConMon).
Experience advising or consulting customers on enterprise network solutions and technical integration approaches.
Knowledge of enterprise networking principles, protocols, architecture, and operational dependencies.
Experience leading technical briefings and stakeholder discussions using Microsoft Teams.
Experience developing clear, concise technical documentation, including architectural blueprints, onboarding guidance, and executive summaries.
Ability to engage executive leadership, communicate technical recommendations, and build consensus across multiple stakeholder organizations.
Ability to translate complex technical information into actionable recommendations for technical and non-technical audiences.
Active Secret security clearance.
Must meet applicable security investigation and eligibility requirements for access to classified information.

Nice To Haves

Experience supporting meshONE-T network environments and associated integration considerations.
Experience architecting classified networks and evaluating security considerations associated with interconnected architectures.
Experience in systems engineering, network architecture, or cross-domain solutions supporting secure interoperability.
Knowledge of the Risk Management Framework (RMF), NIST standards, and their application to cybersecurity compliance and authorization boundaries.
Strong verbal and written communication skills, particularly when presenting complex cybersecurity, architecture, and integration issues to senior leadership.

Responsibilities

Serve as a primary technical advisor and integration liaison between SDIN, meshONE-T, government stakeholders, and external mission partners to advance secure enterprise network interoperability.
Assess classified network architectures, interconnection approaches, and related security considerations in support of mission requirements and architectural decisions.
Ensure interconnected architectures meet applicable risk management and authorization boundaries, and support development of associated RMF packages.
Develop and recommend secure interconnection frameworks that account for network capabilities, technical dependencies, operational constraints, and mission-specific requirements.
Analyze SDIN and meshONE-T technologies, architectures, capabilities, and limitations to identify integration opportunities, dependencies, and potential mission risks.
Support systems engineering and cybersecurity architecture discussions to align integration recommendations with security requirements and established risk management processes.
Evaluate network onboarding approaches, implementation timelines, organizational responsibilities, cost models, and operational considerations.
Facilitate technical coordination among network design teams, systems engineers, cybersecurity stakeholders, and program leadership to resolve integration challenges and establish common architectural understanding.
Develop technical analyses, architectural recommendations, cost-benefit assessments, onboarding guidance, and executive-level briefings for program decisions and enterprise governance reviews.
Communicate network and cybersecurity concepts—including interconnection risks, authorization dependencies, bandwidth constraints, costs, and deployment schedules—to technical and non-technical decision makers.
Identify integration challenges, cybersecurity dependencies, and potential risks early, and recommend mitigation approaches.
Build consensus across government organizations, engineering teams, and mission partners to advance coordinated integration strategies and secure, resilient space mission infrastructure.
Support secure interoperability between SDIN and meshONE-T by providing architecture assessments, integration strategies, technical recommendations, and leadership engagement.
