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. 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 Antares is seeking a Research & Development Software Engineer to build the software systems that enable fast, rigorous experimental engineering across our R&D organization. This role supports test campaigns, prototype development, lab systems, engineering analysis, and verification and validation activities by creating the tools, automation frameworks, data workflows, and hardware/software interfaces that allow engineers to collect high-quality data and make better technical decisions. The ideal candidate is a strong software engineer who is comfortable near hardware: someone who can write production-quality Python and C++, debug DAQ or networking issues in a lab, structure experimental data, build tools that other engineers actually use, and bring software engineering discipline to a fast-moving R&D environment. We are looking for someone who can operate across the stack, from quick analysis scripts to durable internal tools and test infrastructure, while helping establish the practices and alignment needed for R&D software and V&V workflows to scale. Roles & Responsibilities: - Build software-hardware interface tools that support R&D testing, experimental campaigns, prototyp
