Specialist Lab Piping Designer (Buildings)

General Matter enriches uranium. We are designing, building, and operating the world’s lowest-cost enrichment services in the US, restoring America’s ability to produce nuclear fuel to power AI, advanced manufacturing, and critical industries. Our mission is to make nuclear energy the cleanest, safest, and most affordable source of baseload power, driving a nuclear Renaissance and enabling a post-scarcity society. Backed by top venture capital firms and incubated inside Founders Fund, we are a lean, world-class team of engineers and operators with a culture of urgency, accountability, and transparency.

About the role

We’re looking for a Specialist Lab Piping Designer to lead the design of complex fluid and gas distribution systems for our most sensitive R&D, industrial, and high-stakes infrastructure projects. This role sits at the intersection of process engineering and architectural coordination, requiring a designer who understands that a wet lab or cleanroom is only as functional as the high-purity systems supporting it. You will architect the routing, containment, and point-of-use delivery for specialized gases and high-purity water systems, ensuring seamless integration into the building’s structural and mechanical fabric while adhering to the highest standards of safety and contamination control.

Responsibilities

• Design and engineer comprehensive laboratory piping systems, including high-purity specialty gases such as N2, compressed air, vacuum, and RODI (Reverse Osmosis/Deionized) water systems.
• Prepare high-fidelity design packages in Revit, owning the 3D coordination of sloped waste lines, gas manifolds, and overhead service carriers within complex ceiling voids.
• Specify materials and components appropriate for the medium, ranging from orbitally welded stainless steel for high-purity gases to acid-resistant neutralized waste piping for wet labs.
• Develop P&IDs (Piping and Instrumentation Diagrams) and flow schematics that define system logic, pressure regulation, and emergency shut-off protocols.
• Lead multidisciplinary coordination to ensure piping routes do not conflict with structural bracing, HVAC ductwork, or electrical busways, maintaining strict architectural clearances.
• Ensure code compliance with NFPA 45 (Standard on Fire Protection for Laboratories using Chemicals), NFPA 99 (Health Care Facilities Code), and ASME B31.3 (Process Piping).
• Support construction and commissioning by performing submittal reviews and technical field inspections to verify the integrity of specialized joints and purges.

Requirements

• Bachelor’s degree in Mechanical Engineering, Architectural Engineering, or Architecture.
• 8+ years of experience in specialized piping design for R&D, healthcare, or semiconductor facilities.
• Advanced proficiency in Revit and AutoCAD, specifically in creating parametric pipe types and complex 3D assemblies for laboratory equipment.
• Deep technical knowledge of laboratory-grade plumbing, gas cabinet integration, and high-purity water generation.
• Ability to work in a fast-paced environment, balancing precision in micro-level piping details with the scale of massive industrial facility design.

Skills

• Professional Engineer (PE) or AIA license is highly preferred.
• Experience with BIM automation (Dynamo or Python) to streamline pipe routing and automated pressure drop calculations.
• Prior experience in nuclear or pharmaceutical environments, where containment and high-integrity piping are mission-critical.
• Familiarity with seismic bracing for piping systems in high-seismic zones.
• Strong communication skills, with the ability to translate complex P&IDs into clear architectural layouts for project stakeholders.

Why General Matter

• Scale: Work on specialized systems for a massive, first-of-its-kind enrichment facility.
• Complexity: Solve unique challenges of routing hazardous and high-purity media in a high-security industrial context.
• Innovation: Join a team that values digital engineering and "hands-on" technical excellence from design through construction.

Pay

The base salary range for this role is $90,000–$175,000 annually. Compensation bands are determined by role, level, location, and alignment with market data. Individual level and base pay is determined on a case-by-case basis and may vary based on job-related skills, education, experience, technical capabilities, and internal equity. In addition to base salary, full-time hires may be eligible for long-term incentives in the form of stock options.

Benefits

• Medical, vision, and dental coverage.
• Access to a 401(k) retirement plan.
