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. The Antares team hails from SpaceX, the White House, the Pentagon, the Department of Energy, MIT, Rigetti Computing, General Atomics, Relativity Space, Ursa Major, and National Laboratories like Idaho, Oak Ridge, Los Alamos, and Savannah River. Antares has raised over $600M in venture capital from top-tier investors and has hundreds of million-dollars on contract with the military services, NASA, and the Department of Energy. **About the Team** As an R&D Machinist, you will be at the forefront of our company’s critical operations in a fast-paced, innovative environment. You will take ownership of prototyping, machining and assembly operations, ensuring attention to detail and proper documentation as we develop next-generation nuclear systems.   **Roles and Responsibilities:** - Set up, operate, and troubleshoot multi-axis CNC mills (3, 4, 5-axis) and/or live tooling lathes for development hardware and test fixtures - Monitor, replace, and re-set cutting tools - Perform deburring on parts as necessary - Provide feedback to engineering to improve manufacturability of various components - Complete work instructions and other process documentation - Work across graphite, stainless, and high-temp alloys   **Basic Qualifications:** - High school diploma or GED - Ability to read and understand G-code, engineering drawings, GD&T   **Preferred Skills & Experience:** - Experience with machining stainless steel, exotic alloys (Inconel), and/or graphite - Experience operating Fanuc CNC controllers - Able to read and modify G-code based on the fly based on machine performance - Experience working in an R&D machining environment - Experience working with a quality system (AS9100, ISO 9001, NQA1, or similar) - Able to balance/adjust priorities based on dynamic schedule demands   **Additional Requirements:** - Ability to work long hours and weekends as necessary to support critical milestones - Ability to lift up to 50 lbs unassisted - Bending, stooping, and standing for long periods of time may be needed to perform the tasks of the job   **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.
