Mechanical Design Engineer II

About Us

At Antares our long-term mission is to make clean energy abundant from Earth to the Asteroid Belt. Were fueled by the belief that advanced nuclear energy can strengthen our military solve the climate crisis elevate global living standards and expand humanitys presence in outer space. To achieve our mission were 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 Role

As a Mechanical Design Engineer in our Electronic Hardware youll serve as the Responsible Engineer (RE) for the mechanical design and development of hardware supporting the reactors electronic systems. This includes the design of enclosures equipment racks mounting hardware cable management features and structural supports for control system electronics and associated instrumentation. Youll work closely with electrical controls manufacturing and test engineers to define system layouts enclosure requirements thermal and environmental considerations and verification plans. The ideal candidate has experience designing and releasing electronic hardware assemblies for production creating detailed mechanical drawings and documentation and managing CAD models bills of materials (BOMs) and engineering data within a Product Data Management (PDM) system.

Roles and Responsibilities:

• Design and develop mechanical hardware for reactor electronic systems including enclosures equipment racks mounting hardware cable management and structural support assemblies.

• Create and maintain 3D CAD models manufacturing drawings bills of materials (BOMs) and engineering documentation to support fabrication and product release.

• Perform engineering calculations and analyses to validate the structural thermal and environmental performance of mechanical hardware.

• Collaborate with electrical controls manufacturing and test engineers to define mechanical interfaces packaging layouts and installation requirements.

• Support prototype fabrication testing design verification supplier engagement hardware deployment and the resolution of manufacturing assembly and field issues.

• Maintain engineering configuration within the Product Data Management (PDM) system and participate in design reviews throughout the product development lifecycle.

Basic Qualifications:

• Bachelors degree in Mechanical Engineering Aerospace Engineering Nuclear Engineering or a related engineering discipline.

• 2 years of professional experience designing and developing mechanical hardware for electronic systems including enclosures mounting hardware racks or structural support assemblies.

• Experience creating 3D CAD models detailed engineering drawings and bills of materials (BOMs) for production hardware.

• Demonstrated ability to perform engineering calculations to size and validate mechanical components and support structures.

• Familiarity with geometric dimensioning and tolerancing (GD&T) and standard manufacturing processes for fabricated and machined components.

• Experience managing engineering documentation revisions and product structures within a Product Data Management (PDM) or Product Lifecycle Management (PLM) system.

• Demonstrated ability to collaborate effectively with multidisciplinary engineering teams including electrical controls manufacturing and test engineers while clearly communicating technical information to both technical and non-technical stakeholders.

Preferred Skills & Experience:

• Masters degree in Mechanical Engineering Aerospace Engineering Nuclear Engineering or a related engineering discipline.

• Experience designing electronic enclosures equipment racks mounting hardware and structural support assemblies for demanding operating environments.

• Knowledge of electronic packaging principles including thermal management vibration isolation EMI/EMC considerations nuclear radiation shielding cable management and environmental sealing.

• Experience performing structural and thermal analysis using engineering tools such as ANSYS Femap COMSOL Multiphysics or equivalent FEA software.

• Experience designing for manufacturing and assembly (DFMA) including sheet metal machined welded and fabricated components.

• Experience managing CAD models engineering drawings and product structures within a Product Data Management (PDM) or Product Lifecycle Management (PLM) system.

• Experience in the nuclear aerospace defense robotics or other highly regulated or high-reliability industries.

Additional Requirements:

• Ability to work long hours and weekends as necessary to support critical milestones.

Location:

• We are located in Torrance CA in a 322000 square foot brand new facility featuring large open spaces for team collaboration R&D and production as well as easy access

Culture

At Antares we like to specifically tie each role to our founding documents set of valueshere 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 thats how its 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 cant 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. Question every fundamental assumption
