Senior, Civil Engineer

As a Senior Civil Engineer, you will lead the development of deployment sites that support safe, efficient, and cost-effective reactor installation. You'll evaluate prospective sites, develop standardized civil infrastructure, and work with multidisciplinary engineering teams to create modular site designs that can be deployed repeatedly with minimal site-specific customization. This role spans the full project lifecycle—from customer site evaluation and conceptual planning through detailed design, permitting, construction, commissioning, and fleet deployment. You'll help establish the civil engineering standards and deployment methodologies that enable Antares to scale reactor deployments while maintaining the highest standards of safety, quality, and constructibility. Success in this role requires close collaboration with reactor, structural, mechanical, electrical, licensing, manufacturing, construction, and operations teams to ensure each deployment site is optimized for rapid installation, long-term operation, and regulatory compliance.

Roles and Responsibilities:

• Lead civil engineering activities supporting deployment of the Antares R1 microreactor.
• Evaluate prospective deployment sites for geotechnical conditions, grading, drainage, utilities, transportation access, constructibility, environmental constraints, and permitting requirements.
• Develop standardized site layouts that enable repeatable deployment across commercial, defense, and government applications.
• Design site grading, drainage systems, stormwater management, access roads, equipment pads, underground utilities, and civil infrastructure.
• Develop reactor site layouts including reactor silos, balance-of-plant facilities, electrical infrastructure, security systems, and operational support facilities.
• Coordinate geotechnical investigations and incorporate subsurface conditions into foundation and site designs.
• Work closely with structural engineers to develop foundations, reinforced concrete structures, retaining walls, and below-grade facilities.
• Coordinate with reactor, mechanical, electrical, controls, manufacturing, licensing, and construction teams to optimize deployment designs.
• Support transportation planning, heavy-haul logistics, crane studies, equipment installation, and construction sequencing.
• Prepare engineering calculations, specifications, design drawings, cost estimates, and construction packages through conceptual, preliminary, and final design.
• Support permitting activities including grading permits, stormwater permits, environmental reviews, utility coordination, and site development approvals.
• Interface with customers, EPC contractors, government agencies, and regulatory organizations throughout project execution.
• Support construction, commissioning, startup, and lessons learned to continuously improve standardized deployment designs.
• Develop engineering standards, design guides, and best practices that improve deployment speed, quality, and repeatability.

Basic Qualifications:

• Bachelor's degree in Civil Engineering, Mechanical Engineering, or a related field.
• 7+ years of experience in civil engineering supporting industrial, power generation, energy, defense, or large infrastructure projects.
