Designer/Detailer (Mechanical/Structural), Modular R&D

Fluidstack; San Francisco (CA); On-site; USD 134,000 - 164,000; Full time

Job summary

Fluidstack seeks professionals to detail modular data center components for fabrication, turning engineering concepts into shop-ready drawings. You will produce structural, piping, and assembly models to fabrication level, ensuring every detail supports fast, accurate manufacturing.

You will work with Tekla/Advance Steel or BIM tools, maintain library standards, and adapt to rapid engineering changes while upholding strict revision control and quality.

Qualifications

• Detail for fabrication: steel, skids, piping, modular assemblies with shop-ready packages.
• Packages include weld symbols, bolt callouts, and dimensions a fabricator needs.
• Maintain library discipline and version control to ensure correct released drawings.

Responsibilities

• Produce the detailed mechanical and structural models and drawings the factory builds from: structures, skids, piping, and assemblies, fully detailed with nothing left to interpretation.
• Detail steel and mechanical systems to fabrication level: connections, penetrations, pipe spools, and BOM-linked parts, complete enough that a fitter never has to guess.
• Turn engineering changes into updated, released drawing packages in days, not weeks, with clean revision tracking throughout.
• Own model hygiene: build and enforce the standards, libraries, and templates that make each subsequent unit faster to detail and harder to get wrong.

About Fluidstack

We exist to make humanity more free. For most of human history, you farmed or you starved. Technology gave people more time for the things they wanted to do, instead of things they had to do. Powerful AI will be the biggest lever for human choice we've ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who don't share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it.

We're singularly focused on delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. We acquire power, design and build data centers, and operate them - with teams spanning hardware and software. Speed and scale are our key differentiators. Come be a part of building civilization-scale infrastructure for AI. We hire people who care deeply about this problem space.

How We Operate

• Extreme ownership. Full autonomy. Own things end to end often taking on scope outside your core role without being asked to get things done.
• Velocity. We drive everything forward as fast as possible.
• First principles. Challenge every assumption. Zero analogy thinking, no egos, the best idea wins.
• Love of the game. The frontier of AI is the most interesting problem of our time. We put in long hours at high intensity to push the frontier forward.

The Modular Team

The Modular team designs and industrializes factory-built data center units, turning first-of-a-kind designs into repeatable products the factory can build again and again.

Examples Of Key Problems The Team Is Working On

• Take modular data center designs from engineering concept to fabrication-ready packages that a shop can build without a phone call.
• Detail the structures, skids, and piping systems inside each unit down to the weld and bolt level.
• Absorb rapid engineering changes across in-flight units without losing revision control or slowing the factory.
• Build the modeling standards, part libraries, and templates that make every next unit faster to detail than the last.

Role Scope

• Produce the detailed mechanical and structural models and drawings the factory builds from: structures, skids, piping, and assemblies, fully detailed with nothing left to interpretation.
• Detail steel and mechanical systems to fabrication level: connections, penetrations, pipe spools, and BOM-linked parts, complete enough that a fitter never has to guess.
• Turn engineering changes into updated, released drawing packages in days, not weeks, with clean revision tracking throughout.
• Own model hygiene: build and enforce the standards, libraries, and templates that make each subsequent unit faster to detail and harder to get wrong.

What We're Looking For

• You've detailed for fabrication: structural steel, skids, piping, or modular assemblies, in a fab shop, skid builder, or modular manufacturing environment.
• Shops build from your drawings without calling. Your packages carry the weld symbols, bolt callouts, and dimensions a fitter actually needs.
• You model to standards and keep library discipline: parts, templates, and naming conventions stay clean under pressure.
• You handle revision storms without version chaos. When engineering changes land, the released package is always the right one.
• You know how things get made: welds, bends, tolerances, and the clearances real fabricators need to fit up, weld out, and inspect.
• You know what gets red-lined when it's missing, and your detailing has changed because of it.
• Bonus: Tekla or Advance Steel, plant and BIM modeling (Revit, Plant 3D), AWS weld symbols and AISC detailing standards, or BIM coordination experience.
