Engineer Drafter - TS/SCI Polygraph Required

Leidos has an opening for an Engineer Drafter in Reston, Virginia. The primary focus of this position is the creation and modification of detailed engineering drawings, including parts, assemblies, installations, and facility models, based on basic layouts, established references, and standard engineering data. Work is performed using computer-aided design and modeling tools such as CAD, CAM, CATIA, and Building Information Modeling (BIM) software.

In addition to drafting and modeling responsibilities, this role requires the development of technical solutions through collaboration with subject matter experts and stakeholders. The successful candidate will perform deep technical analyses and evaluate impacts to end products and solutions. This position requires the ability to solve complex and often ambiguous technical challenges where complete information may not be readily available. Candidates must demonstrate sound engineering judgment, creativity, exceptional attention to detail, and a commitment to producing high-quality work.

The selected candidate will work as part of an interdisciplinary team of government and contractor personnel in a fast-paced, mission-focused environment within a government facility.

Roles and Responsibilities

• As a member of a characterization team, integrate all-source intelligence, geotechnical data, topographical data, underground infrastructure expertise, and engineering principles to identify and model facility functions (missions) and physical configurations, including layouts, structures, mission systems, support systems, and associated components.

• Develop detailed 3D BIM models and 2D CAD drawings across multiple engineering disciplines.

• Perform clash detection and coordination among engineering disciplines, identifying and resolving model conflicts and spatial issues prior to design completion.

• Develop, maintain, and enhance project-specific and enterprise BIM libraries, including custom families, templates, metadata, and annotations.

• Audit models to ensure data integrity, spatial accuracy, compliance with Level of Development (LOD) requirements, and adherence to organizational BIM, modeling, and simulation standards.

• Generate customer-required deliverables, including technical reports, detailed measurements, material schedules, cross-sections, and supporting documentation directly from BIM models.

• Participate in model coordination meetings with clients, stakeholders, and cross-functional teams.

• Execute detailed engineering drawings and layouts in accordance with established drafting standards and engineering best practices.

Required Education, Skills, and Experience

• Must possess in-scope and active TS/SCI Polygraph clearance for consideration. U.S. Citizenship is required.

• Expert knowledge of, and demonstrated ability to apply, advanced technical principles, theories, and concepts.

• Bachelor's degree with 8+ years of relevant experience, or a Master's degree with 6+ years of relevant experience. Additional relevant experience may be considered in lieu of a degree.

• Experience in Civil Engineering, Structural Engineering, Protective Engineering, or a related discipline applicable to Building Information Modeling (BIM).

• Excellent written and verbal communication skills, including the ability to effectively brief and interact with senior government and organizational leaders.

Preferred Qualifications

• Working knowledge of protective engineering principles and physical force protection measures.

• Experience with Autodesk Revit, Autodesk AutoCAD, and BIM software, methodologies, and best practices.

• Experience with VENTSIM, ETAP, or other infrastructure modeling and simulation tools.

• Military, intelligence community, or defense-related experience.

• Construction experience involving mission-critical facilities, tunneling, underground structures, or large-scale excavations.

• Experience with design reviews, engineering modifications, specifications development, dimensioning, and document management.

• Experience developing and implementing BIM-related workflows, standards, and processes.
