Electrical Integration Engineer

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

Every system we build is tied together by wire and some of that wire carries safety-class functions. As our Electrical Integration Engineer, you'll own that layer end to end: from wire and connector selection, through schematic and routed 3D model, through a release package a supplier can build from without a single clarifying email, all the way to harnesses coming off the bench on our own floor.

In this role you would be responsible for interfacing harnesses between systems and the internal harnesses inside each electrical system and distribution cabinet, across both testbed and safety-class applications. Beyond the design itself, you'll own the toolchain, the release process, the BOM, the supplier relationships, and the in-house build. If you like being the person who defines how something gets done, not just the person doing it, this role is built for that.

Roles and Responsibilities:

- Own harness CAD design: Route, bundle, and constrain every harness in the 3D model: interface harnesses between systems and internal harnesses for each electrical system and distribution cabinet. Manage bend radii, service loops, strain relief, clearance to thermal and moving hardware, and connector accessibility for both assembly and field service. - Own harness schematics: Develop and release wiring diagrams, wire lists and from-to charts, connector pinout tables, splice topology, and shield and grounding schemes for every harness. - Own component selection: Choose wire type and gauge against current, derating, voltage drop, insulation, temperature, radiation, and flex requirements. Select connectors, contacts, backshells, and sealing. Specify and qualify the crimp tooling, dies, and calibration and pull-test regime that go with them. - Design to safety-class requirements: Apply physical separation and independence between redundant divisions, respect qualification envelopes for cable and terminations, and maintain the design records and requirements traceability that support I&C classification and licensing. - Own the harness design review and release process: Define what a review gate looks like, what a complete package contains, and how changes move through ECO and PLM under our QA program. Then improve it, including the software integrations that make release faster and less error-prone. - Be the responsible engineer for our harness design software: Partner with our software applications engineers to improve how we build harnesses: connector and part library management, schematic-to-3D data flow, design rule checks, and automation of repetitive deliverables. Own license administration, version upgrades, and escalation with the tool vendor. - Support supplier selection and qualification: Work alongside supply chain and quality to evaluate harness houses and electrical panel builders, capability assessments, supplier audits and approved supplier list entry, RFQ technical packages, quote reviews, and DFM feedback that lowers cost and build time. - Own build packages and supplier technical communication: Hand off the package, resolve drawing questions, disposition deviations and nonconformances, support first article and source inspection, and drive workmanship and quality escalations to closure. - Own the harness BOM and material readiness: Keep the BOM accurate and released, and work with supply chain and quality so parts land on site on time and clear receiving inspection, including certificates of conformance, lot traceability, and commercial grade dedication where hardware is destined for safety-class use. - Manage in-house harness builds: Direct our harnessing technicians day to day: prioritize the queue, prepare formboards and work instructions, run operator training and crimp certification, set the workmanship bar, maintain inspection and test records, and be on the bench when something doesn't go together the way the model said it would.
