Senior Mechanical Design Engineer Reactivity Controls

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.

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

As the Responsible Engineer for Reactivity Controls Mechanical you will lead
the design development testing and validation of the mechanical systems that
govern reactor reactivity and ensure the safe operation of the reactor. You will
architect and build the mechanical mechanisms that interface with electrical and
software subsystems collaborating closely across disciplines to define system
architecture requirements and documentation.

The ideal candidate 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:

• Design build and test the reactors control mechanisms hardware and
  assemblies.

• Concept and develop custom actuation solutions including mechanisms
  linkages interfaces and instrumentation.

• Define design criteria requirements system architecture and
  verification/validation test plans.

• Collaborate closely with cross-functional teams across thermal structural
  neutronics controls and simulation disciplines.

• Engineer components for high-temperature high-stress and radiation
  environments using metals ceramics and other advanced materials.

• Perform design-for-manufacturability (DFM) assessments and execute
  tradeoffs across performance cost schedule and risk.

• Conduct mechanism trade studies document findings and present
  recommendations to senior leadership

Basic Qualifications:

• Bachelors degree in engineering

• 5 years of experience in a full-cycle design engineering roles
  encompassing hands-on experience with CAD analysis build and test

• Experience with kinematic synthesis pneumatic/hydraulic actuation
  mechatronics and instrumentation

• Experience with FMEA including structure strength stability and fatigue
  failure modes

Preferred Skills & Experience:

• Masters degree in engineering

• 7 years of experience in a full-cycle design engineering roles
  encompassing hands-on experience with CAD analysis build and test

• Experience in the Nuclear Aerospace or Robotics industries

• Experience in a demanding fast-paced development environment

• Experience with design engineering tools such as NX 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

Location

• We are located in Torrance CA in a 145000 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 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
