Atoms builds Physical AI— real-world robots for the industries that move civilization forward, starting with food, mining, and transport. Our systems are designed to understand, predict, and control the real world with precision, turning complex physical operations into something more reliable, more scalable, and more productive.

What you’ll do

• Lead plumbing system design and analysis — domestic water, sanitary/waste, grease waste, natural gas, and fire protection coordination — for new and retrofit facilities across Atoms' portfolio.
• Prepare plumbing calculations, drawings, and specifications for permit submission across multiple jurisdictions.
• Design and size grease interceptors, hot water systems, and process piping for high-volume commercial kitchen and food production facilities.
• Partner with Structural, Building Design, Civil, and MEP consultant teams to resolve system conflicts and keep designs constructible and cost-effective.
• Review and respond to plan check comments from Authorities Having Jurisdiction (AHJs) and utility/water providers to keep permitting on schedule.
• Evaluate vendor and manufacturer plumbing and fixture submittals for code compliance and site suitability.
• Support construction administration, including RFIs, submittal review, and field observation for plumbing systems.
• Build and refine standardized plumbing details and design templates that can be reused across Atoms' different business lines to support rapid, repeatable deployment.

What we’re looking for

• 7–10 years of plumbing engineering experience, including design for commercial, industrial, or food service facilities
• Professional Engineer (PE) license preferred; ability to obtain additional state licensure/reciprocity as needed
• Demonstrated experience with domestic water, sanitary/waste, grease waste, and gas piping system design
• Working knowledge of IPC/UPC plumbing code, local amendments, and relevant health department requirements for food facilities
• Experience preparing permit-ready plumbing drawings and independently managing AHJ plan review cycles

Why join us

At Atoms, you’ll work on one of the defining challenges of our time—bringing automation into the physical world to drive real, lasting impact. We exist to uncover valuable unknown truths and turn them into progress, which means constantly pushing beyond what’s known and building what doesn’t yet exist. The work is ambitious and often challenging, but it’s grounded in a shared sense of purpose and a team committed to seeing it through together. Our work only matters if it serves others, and we know that meaningful progress depends on the trust of the people we serve and the strength of our team—so we invest in both, creating an environment where you can do your best work and grow.
