Los Angeles, United States Antares Full time

Senior Mechanical Design EngineerAbout UsAt Antares, our mission is driven by the conviction that a new era of energy abundance is key to elevating global living standards and meeting the needs of Earth's changing climate. We envision a future where affordable, reliable, and sustainable modern energy is as accessible in remote communities on Earth as it is in missions to the Asteroid Belt. To achieve that goal, Antares will become the de facto experts in nuclear microreactor development, test, and operation by making the world's first mass-produced rapidly-deployable reactors. Antares is set to achieve timely certification and production scale by first partnering with the U.S. Department of Defense, where we can unlock unique capabilities not possible with current energy solutions, by untethering austere and contested locations from fossil fuel logistics.Formed in 2023, the Antares founding team hails from SpaceX, The White House, MIT, Rigetti Computing, and The Air Force. To date, they have raised over $8M in capital from top-tier investors, including Caffeinated Capital and Susa Ventures.About the RoleAs a member of the engineering team, you will be Antares' expert on mechanical design. You will work on all reactor, power conversion, and ground support equipment subsystems to ensure simplicity, manufacturability, and reliability in extreme maintenance-free environments. You will help develop and document our design best practices, requirements, and workflow. The ideal candidate will have a proven track record of successful mass and form-efficient design, experience with exotic materials and superalloys, and will have at least a light background in structural analysis and test. Additionally, you will provide nuanced input into the system architecture trades and take a lead role in managing outsourced designs and commercial off the shelf parts. ResponsibilitiesDesign state-of-the-art components, structures, and mechanisms for any and all subsystemsGenerate and maintain detailed drawings, component specifications, analysis and risk assessments.Participate in root cause investigations that arise in development, production, test, integration, and field operation to implement corrective actions to prevent repeat failures.Define the standard process and workflow for rigorous part designInform system-level architecture, with component capabilities and vulnerabilities in mind, to minimize overall unit costBasic QualificationsBachelor's degree in an engineering discipline or physics5+ years of experience designing and analyzing mechanical systems via professional work experience, project/research-based student experience, or a combination of both.Preferred Skills and Experience Strong interpersonal and collaborative skills, enthusiasm for problem-solving, and desire to optimize modern nuclear design and operation.Master's degree or 5+ years of professional experience in mechanical or aerospace engineering.Experience designing, building, testing, and troubleshooting mechanical systems.Demonstrated track record of high impact / ROI contributionsStrong project management skills and effective communication of technical concepts across multi-disciplinary teams.Hands-on experience with fluid, gas, or high-voltage systems.Leadership experience on a project or research team.Experience using test instrumentation and control components (e.g. pressure transducers, thermocouples, strain gages, relays, solenoid valves, etc.).Knowledge of electro-mechanical devices, actuators, motors, valves, regulators, or other fluid and position control devices.Understanding of fundamental principles in fluid systems and solid mechanics.Broad knowledge of materials science and material selections, especially for nuclear applicationsAdditional RequirementsBased in or ability to relocate to Los Angeles to work in person at our Redondo Beach officeAbility to work long hours and weekends as necessary to support critical milestonesCultureHere 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 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."Craftsmanship - We also focus on the inputs. We aspire to high-quality engineering for its own sake. As such, we invest in personal growth, learning, and developing a long-term career path for exceptional individual contributors. We embrace a beginner's mindset, share knowledge, and never condescend the curious.Loyally Collaborative - Team > Self. We win together. There is nothing more precious than a high-performing team.ITAR RequirementsTo conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
