Director, Construction - Reactor Deployments

About UsAt Antares, our long-term mission is to make clean energy abundant from Earth to the Asteroid Belt. We’re fueled by the belief that advanced nuclear energy can strengthen our military, solve the climate crisis, elevate global living standards, and expand humanity's presence in outer space. To achieve our mission, we’re building mass-producible, inherently safe, deployable microreactors that can be used terrestrially, underwater, and in space.Formed in 2023, the Antares team hails from SpaceX, The White House, MIT, Rigetti Computing, The Air Force, General Atomics, Relativity Space, Ursa Major, and National Laboratories like Los Alamos, Idaho, and Oak Ridge. Antares has raised over $130M in venture capital from top-tier investors and has over $13M in government funding.About The TeamThe Reactor Deployments team is responsible for delivering Antares systems from factory to field. We operate at the intersection of engineering, construction, and operations—ensuring each deployment site is designed, built, and commissioned to the highest standards.This team partners closely with design engineering, manufacturing, regulatory, and external stakeholders to bring first-of-a-kind energy infrastructure online.Roles and Responsibilities:As Director of Construction at Antares, you will lead the planning and execution of all site development and construction activities for reactor deployments. You will own the end-to-end construction strategy—from early site design input through field execution.You will serve as the critical bridge between engineering and the field, ensuring designs are constructible and projects are delivered safely, on schedule, and at high quality. You will be responsible for driving cost efficiency and ensuring timely project completion to meet Antares’ aggressive deployment timelines.You will also build and lead the construction function, managing contractors, developing processes, and scaling Antares’ deployment capabilities.Own construction strategy and execution for all reactor deployment sitesDrive projects to completion on aggressive timelines while maintaining safety and quality standardsMinimize cost and schedule through strong planning, contractor management, and execution disciplinePartner with design engineering to ensure site requirements, constructability, and field constraints are incorporated earlyEstablish construction standards, processes, and best practices across deploymentsEnable flexible deployments to meet customer needs including above grade and below grade constructionLead budgeting, scheduling, and cost control across multiple concurrent projectsOversee civil, EPC, and construction subcontractors, holding them accountable to performance, cost, and scheduleBuild and manage relationships with site owners, utilities, and local stakeholdersEnsure compliance with safety, environmental, and regulatory requirementsIdentify and resolve construction risks and execution challenges in real timeSupport permitting, site selection, and pre-construction development effortsBuild and scale a high-performing internal construction and field operations teamBasic Qualifications:10+ years of experience in construction management, infrastructure delivery, or large-scale project executionExperience managing contractors or subcontractors across multiple sitesStrong understanding of civil works, site development, and construction systemsAbility to interpret engineering drawings and drive design-for-construction decisionsPreferred Skills & Experience:Demonstrated leadership experience building or managing teamsProven track record delivering complex projects on schedule and within budgetExperience in energy, industrial, or mission-critical construction (e.g., power plants, data centers, defense infrastructure)Direct experience with nuclear site construction or nuclear-adjacent infrastructureFamiliarity with DOE, DoD, NRC, or other regulated project environmentsExperience with first-of-a-kind (FOAK) or highly technical projectsBackground bridging design engineering and field executionExperience scaling construction operations in a high-growth environmentAdditional Requirements:Ability to travel to sites as neededLocationWe are located in Torrance, CA in a 322,000 square foot, brand new facility featuring large open spaces for team collaboration, R&D, and production, as well as easy access to the 405, 105, and 110 freeways. Our facility is in the heart of Los Angeles' vibrant emerging tech ecosystem alongside many other high growth startups and enterprises. CultureAt Antares, we like to specifically tie each role to our founding document’s set of values–here are the top five cultural values we think you should believe at your core to be successful:Think in Systems - Energy and Defense are complex ecosystems with numerous stakeholders with competing priorities, conflicting policies, perverse incentives, and emergent and path-dependent properties. First principles thinking alone is insufficient. Think probabilistically and then take action. “If you want to be certain, then you are apt to be obsolete.” Over-optimizing the components often degrades the systemObsess over the End User - The customer and end user are often not the same. We will never build globally competitive commercial products if we lose sight of our end users and their entire interaction with the product life cycleBe Unconstrained by Convention - Our only limits are the laws of physics. Many, even experts, will say what we are working on is impossible. They said the same about SpaceX reusing rockets. Generationally impactful companies, by definition, must accomplish the seemingly impossible. If it were easy, it would have already been done. Never shy away from a solution because it has never been tried before, and never choose to do something because that's “how it's always been done”Go Where the Work Is - Never miss a chance to meet a customer, user, or stakeholder face to face, even if that means hopping on a plane. If you can’t make it, find a teammate who can channel your intentions and go in your place. Deep work can be done from anywhere, but we believe teams are built in person, and aim to maximize our time togetherOperate in the Grey - Embrace nuance in pursuit of truth.
