We are seeking aCost Engineer/Senior Cost Engineerto support the National Security Space Enterprise. In this role, you will support or lead cost analyses, evaluate technical and programmatic data, and develop cost estimating models and methodologies. You will contribute to advancing cost engineering capabilities through the development of tools, analytical frameworks, and data approaches that enable defensible, decision-ready cost products, while integrating cost with schedule and risk insights to inform acquisition and funding decisions.

Work Model: This position is full-time and requires on-site work at one of the following locations:El Segundo,CA;Chantilly, VA; Crystal City, VA; Greenbelt, MD;Huntsville, AL; Albuquerque, NM; Colorado Springs, CO,offering an in-person work model that combines 4 or more regular onsite workdays per week and remote flexibility as the business needs allow.

WhatYouBe Doing

• Advisecustomers onacquisition strategies that balance cost, schedule, and risk to enable mission success

• Participate in space system design and evaluation teams and may lead the cost analysiscomponentandAdvise customers on acquisition strategies, balancing cost, schedule, and risk

• Contribute to space system design and evaluation efforts byprovidingcost insights andidentifyingcost and schedule risks

• Develop life cycle cost estimates and trade studies to support program direction, funding strategies, and investment decisions

• Work with customers and program offices to develop cost methodologies grounded in cost engineering practices and estimating principles

• Conduct cost research and build ormaintaindatabases, tools, and methodologies that strengthen cost estimating capabilities

• Evaluate contractor proposals and program artifacts toidentifycost drivers, risks, and potential gaps

• Apply cost and analytical methods across a range of acquisition environments (e.g., rapid acquisition, OTAs,fixed-price), adapting approaches to support faster program delivery

• Contribute to team development and technical quality through mentoring and peer reviews
