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. 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 Senior Electrical Engineer at Antares, you will contribute to the architecture, design, testing, and integration of instrumentation and control (I&C) and power distribution systems for advanced nuclear microreactors. You will work closely with systems, mechanical, software, licensing, and test teams to ensure electrical designs meet performance, safety, and regulatory requirements across multiple applications. The role includes hands-on electrical design, hardware development, and preparation of instrumentation and control documentation that supports DOE and NRC licensing Key Responsibilities * Design electrical systems for reactor instrumentation, control, and power distribution, from early concept through detailed implementation. * Develop schematics, wiring diagrams, and interface definitions for sensors, control hardware, and electrical subsystems. * Review and provide feedback on schematics, wiring diagrams, harnesses, and control panel designs. * Participate in design reviews, ensuring electrical and I&C sections are technically sound and traceable. * Assist with hazard analysis, identifying electrical or instrumentation failure modes and mitigations. * Support test activities including bench testing, HIL/HITL, and integration campaigns. * Collaborate cross-functionally with systems, mechanical, software, and licensing teams. Basic Qualifications * 5+ years of relevant electrical engineering experience in the design, development, integration, or testing of electrical systems and hardware. * Bachelor’s degree in Electrical Engineering, Systems Engineering, or related field. * Strong grasp of electrical fundamentals, including DC and AC circuits, impedance, and transient behavior. * Ability to create, read, and review electrical schematics and wiring diagrams. * Familiarity with electrical design, simulation, or PCB layout tools (e.g., SPICE-based simulators, schematic capture, or layout review tools). * Hands-on experience with lab instrumentation such as oscilloscopes, multimeters, power supplies, and signal generators. * Ability to reason about failure modes and safe states in electrical or control systems. * Comfort working in fast-paced, ambiguous hardware development environments. * Strong written and verbal communication skills. Preferred Skills & Experience * Experience working in regulated or safety-critical environments (nuclear, aerospace, defense, maritime, or industrial). * Understanding of fail-safe design, redundancy, voting logic, or diversity in control systems. * Hands-on experience with hardware bring-up, troubleshooting, and root-cause analysis. * Exposure to HIL/HITL testing, automated test frameworks, or data acquisition platforms. * Familiarity with relevant codes, standards, or guidance (e.g., IEEE, IEC, DOE nuclear standards). * Familiarity with GDE-987 processes or similar hardware qualification paths. * Experience contributing to formal design reviews, hazard analyses, or configuration-controlled documentation. * Demonstrated ability to take ownership of hardware problems, work through ambiguity, and drive issues to closure. 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 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 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.
