21, LLC is a Charleston, South Carolina-based small business and technology consulting firm specializing in solving complex business problems for global business and government clients. Our philosophy is simple – deliver quality through high performance to our clients; provide value to our clients through the ability to streamline, measure, and improve their business processes via business intelligence and business architecture; and practice professional integrity by being trustworthy and reliable.

Our expertise has proven highly successful in helping organizations recognize greater value by aligning their strategy and objectives to technology and execution.

The Naval Information Warfare Center Atlantic (NIWC LANT) Cloud Computing Innovation, Transformation, and Integration (CLOUD CITI) Division is tasked with providing hosting environments and platforms for Navy applications, as well as other DoD and Homeland Security (HLS) applications utilizing both Component Enterprise Data Centers (CEDCs) and Commercial Cloud Service Providers (CSPs) as hosting platforms. As part of the program, we are seeking an experienced Senior Service Now Developer to lead the evolution of our Service Now platform from a foundational ITSM implementation into a strategic enterprise platform.

This is a hands‑on technical role requiring an individual who can both define platform strategy and personally collaborate on designs; and develop, configure, and implement solutions across the Service Now ecosystem.

The successful candidate will serve as the senior technical expert for the platform, driving the expansion of Service Now capabilities including CMDB, CSDM, Strategic Portfolio Management (SPM), integrations, workflow automation, and platform governance. While this role will provide technical leadership and input on strategic direction, it is expected that the individual will remain actively involved in day‑to‑day development, configuration, integration development, troubleshooting, and solution delivery.

This position is ideal for someone who enjoys balancing architecture, strategy, and hands‑on execution to deliver measurable business outcomes, and enjoys building sustainable solutions rather than delivering short‑term projects. You will serve as a trusted technical leader, helping guide the customer's Service Now journey from foundational ITSM capabilities to a mature enterprise platform that includes CMDB, CSDM, SPM, advanced analytics, automation, and integrations.

• Serve as the technical lead and hands‑on developer for Service Now platform initiatives.
• Design, develop, configure, test, and deploy Service Now solutions across multiple modules.
• Develop workflows, business rules, client scripts, integrations, custom applications, and automation solutions.
• Troubleshoot complex platform, integration, and data quality issues.
• Provide technical mentorship while actively contributing to platform administration and development.
• Contribute to the Service Now roadmap and platform modernization strategy.
• Establish architecture standards, development best practices, and governance processes.
• Ensure platform scalability, security, performance, maintainability and adherence to platform best practices.

• Support the implementation and maturity of CMDB, CSDM, and Asset Management capabilities.
• Maintain configuration data models, CI relationships, and governance processes.
• Improve data quality and operational effectiveness through standardization of processes and automation.
• Support implementation and administration of Service Now SPM capabilities, including Demand Management, PPM, Resource Management, Agile Development, Collaborative Work Management and Strategic Planning.
• Collaborate with business leaders to align portfolio management processes with organizational goals.

• Design and support integrations using REST APIs, Integration Hub, Import Sets, and other enterprise integration…
