The Antares Reactor Deployments team is responsible for bringing the Antares R1 microreactor from the factory to operational service.
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.
Interface with customers, EPC contractors, government agencies, and regulatory organizations throughout project execution.

Responsibilities

Lead civil engineering activities supporting deployment of the Antares R1 microreactor.
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.

Requirements

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.
Experience with site development including grading, drainage, utilities, roadway design, and civil infrastructure.
Experience coordinating multidisciplinary engineering projects.
