What Your Job Will Be Like:

We are seeking a cleared, experienced Space Systems Engineer to be an on-site customer liaison that sits with the US Space Force customer in Colorado Springs, Colorado. The person occupying this role will represent Sandia programs to the Operational Test & Training Program Office, Space Warfighting Analysis Center, and Space Security and Defense Program Office.

The selected candidate will serve as an on-site technical representative and systems-engineering integrator, representing Sandia's modeling, simulation, mission-analysis, and systems-engineering capabilities to multiple government customers. The role requires the technical judgment and leadership to build trusted customer relationships; translate complex mission needs into executable technical and analytic work; coordinate distributed Sandia teams and integration partners; evaluate the mission relevance and fitness-for-use of technical results; and communicate technically rigorous, decision-quality findings to senior stakeholders.

On any given day, you may be called on to:

  • Serve as Sandia's on-site technical representative for government customers supporting classified space security, defense, test, training, modeling and simulation, and mission-analysis activities; provide customer-facing systems-engineering coordination and technical leadership across Sandia technical teams and integration partners.

  • Build trusted working relationships with customer technical leaders, program managers, analysts, and operational stakeholders, and communicate Sandia capabilities, technical findings, risks, assumptions, and recommendations.

  • Translate customer mission needs and technical questions into executable Sandia model-development and analysis work, including objectives, technical requirements, assumptions, measures, deliverables, and execution plans.

  • Coordinate Sandia-developed model-delivery activities for use in mission-level, system-of-systems, distributed, or high-fidelity simulation environments.

  • Provide systems-engineering and customer-facing coordination for model integration, including intended use, technical interfaces, dependencies, assumptions, data-exchange expectations, configuration needs, verification and validation planning, and resolution of cross-organizational technical issues.

  • Coordinate Sandia organizations conducting mission analysis, modeling and simulation, system assessments, and related technical studies; integrate results into clear products, briefings, and recommendations for customer decisions.

  • Apply technical judgment to help customers and Sandia teams understand the appropriate use, assumptions, uncertainty, limitations, and mission implications of model and analysis results.

  • Identify and facilitate technically appropriate collaboration among customer organizations and Sandia teams, including opportunities to apply existing Sandia capabilities to emerging mission needs.

  • Support Sandia technical program and program-management leadership with technical objectives, statements of work, work packages, milestone plans, customer engagements, and proposals for new or expanded work.

  • Protect classified information and exercise sound professional judgment in handling sensitive mission, customer, technical, and programmatic details.

The person in this role will report daily to the project leads they are supporting and be supervised by a Manager who are all located in Albuquerque, NM. Thus this person will be expected to effectively and professionally operate in a remote location with minimal supervision. Regular onsite work in Colorado Springs, CO is expected of the selected applicant.
