CAD Drafter

About Us At 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 Role In this role, you will create and manage large, complex CAD assemblies, build out a common hardware library, and create engineering drawings for our nuclear microreactor. The ideal candidate has expert level proficiency in NX, is extremely detail oriented, and communicates proactively and effectively. The ideal candidate also has a strong track record in designing and developing precision control mechanisms, preferably with experience in robotics or electromechanical systems. You will also contribute to system-level architecture trade studies and support the evaluation and selection of key vendors. Roles and Responsibilities: Create and maintain error-free complex assemblies in NX Identify and correct issues with CAD models and drawings while ensuring CAD models and drawings adhere to modeling best practices Design mechanical parts and assemblies in collaboration with engineering teams Manage part metadata and component library Create part and assembly level drawings with proper application of GD&T Coordinate with sourcing, design engineering, and configuration management on the cut in dates of new components and assemblies Basic Qualifications: 5+ years of experience with CAD in Siemens NX. Experience working in Siemens Teamcenter Proficient in GD&T concepts and application per ASME Y14.5-2009 Good mechanical intuition - excellent at understanding how components interact in larger mechanical systems Preferred Skills & Experience: Bachelor’s degree in engineering 8+ years of experience with CAD in Siemens NX. Previous experience as a CAD Librarian, drafter, or similar Experience in the Nuclear, Aerospace, or Robotics industries Experience in a demanding fast-paced development environment Experience in mechanical design of components from early conceptual phase into production Experience with design and analysis engineering tools such as ANSYS or Femap, and other product lifecycle software Experience with engineering scripting languages such as Python and MATLAB Additional Requirements Ability to work long hours and weekends as necessary to support critical milestones. Ability to travel to customer and mission-relevant locations as needed. Ability to obtain a Top Secret or Top Secret SCI clearance is preferred. Location We 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. Culture At 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 system Obsess 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 cycle Be 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 I s - 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 together Operate in the Grey - Embrace nuance in pursuit of truth.
