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. If that is you, please apply!

About the Role

The Senior Structural Engineer, Modular Construction is an outstanding opportunity for a driven engineer to take real ownership at the forefront of modular data center development. You will lead structural engineering efforts on custom modular systems across a multi-site, multi-state portfolio, from early-stage design through factory production, delivery, and site installation.

This is an owner/developer role with approximately 25% travel. You will manage modular designs, external structural consultants and modular manufacturers, coordinate with civil and MEP engineers, and drive technical alignment across fabricators, GCs, and project teams.

Responsibilities

Design & Standards

• Design and engineer structural steel frameworks and modular systems for data center applications, ensuring accuracy and compliance with project requirements and industry standards throughout

• Perform static, dynamic, and seismic structural calculations for modular frames, stacking configurations, lifting and rigging conditions, transport load cases, and foundation interface connections using ETABS, RISA, RAM Structural Systems, and SolidWorks

• Develop detailed 3D structural models using Revit and AutoCAD 3D; maintain comprehensive model accuracy across design iterations and fabrication releases

• Produce detailed connection designs for module-to-module interfaces, foundation anchorage, and field-assembled structural elements, with a focus on constructability, weld specifications, and tolerance accommodation

• Lead design for manufacturability reviews, translating engineering intent into factory-executable details with clear fabrication tolerances and assembly sequences

• Produce construction drawings, material lists, and cutting schedules to internal and client specifications; coordinate closely with fabrication and warehousing teams to ensure accurate and timely material delivery

• Develop and maintain modular structural basis of design, master specifications, and standard details for Fluidstack's campus portfolio

• Apply and enforce ACI, AISC, AWS D1.1, ASCE 7, IBC, and other industry-relevant design codes and standards across all project phases and fabrication scopes

• Participate in BIM coordination meetings with clients, consultants, and internal teams; present structural calculation reports and technical documentation to clients and design verification partners

• Manage external structural consultants and modular fabricators from schematic through IFC and factory release; review and redline deliverables, enforce standards, and track design quality across engineering and manufacturing workflows

• Field internal and external technical inquiries regarding structural products and systems; develop and expand the team's technical knowledge base

• Develop and drive automation of internal engineering processes to improve speed, accuracy, and repeatability across future projects

• Manage concurrent projects and their deliverables, maintaining schedule alignment across design, permitting, fabrication, and installation workstreams

Permitting & Regulatory

• Lead structural permitting strategy across jurisdictions for modular programs: building permits, factory inspection and certification, special inspections, and structural observation requirements

• Coordinate with state modular program offices, local building departments, third-party inspection agencies, and factory certification bodies

• Manage permit and factory approval schedules as part of the overall project critical path

• Monitor regulatory risk including seismic design categories, wind exposure, transport route restrictions, and jurisdictional modular code acceptance; develop mitigation strategies

Construction & Fabrication Support

• Review fabricator submittals, RFIs, and factory non-conformances for structural scope

• Conduct periodic factory audits and site visits to document structural fabrication quality, dimensional compliance, and installation accuracy

• Collaborate with production teams for design optimization, ensuring structural solutions are practical, cost-effective, and manufacturable at scale

• Manage design changes and change order scope across both factory and field structural work

• Coordinate structural closeout, as-builts, and acceptance with local authorities, special inspection agencies, and modular certification bodies
  

Basic Qualifications

• B.S. in Civil Engineering (Structural emphasis), Structural Engineering, or Mechanical Engineering; M.S. preferred

• 10+ years of structural engineering experience, including significant work on modular, prefabricated, or custom-engineered structural systems and data center or industrial applications

• Professional Engineer (PE) license

• Hands-on experience performing structural analysis and design, including static, dynamic, and seismic calculations, member sizing, connection design, and calculation package development

• Proficient in Revit, AutoCAD, ETABS, RISA, RAM Structural Systems, and SolidWorks

• Working knowledge of IBC, ASCE 7, ACI 318, AISC, and AWS D1.1 standards as applied to modular and prefabricated construction

• Experience working within a BIM environment and participating in BIM coordination workflows

• Familiarity with module transport requirements, lifting and rigging design, and site installation sequencing

• Strong proficiency in Microsoft Office (Excel, Word, PowerPoint) and comfort with engineering data management

• Excellent problem-solving, communication, and collaboration skills; able to work effectively across engineering, fabrication, and project management teams

• Ambitious and career-driven, with a desire to grow into senior leadership as the business scales

Preferred Qualifications

• Experience in hyperscale data center, large-scale industrial, or mission-critical modular facility development

• Exposure to high-seismic, high-wind, or expansive soil site conditions and their implications for modular foundation design

• Experience with factory quality management systems and modular third-party certification programs

• Familiarity with tolerance stack-up analysis, connection detailing for field assembly, and dimensional control programs

• Experience developing or automating internal engineering workflows and design standards

• Owner/developer-side experience (vs. pure consultant, EPC, or fabricator)

• Familiarity with raised floor systems, equipment pad design, and integrated MEP support structures common to modular data center environments

• Experience with steel detailing software (similar to Tekla)

Benefits

• Competitive total compensation package (cash + equity).

• Retirement or pension plan, in line with local norms.

• Health, dental, and vision insurance.

• Generous PTO policy, in line with local norms.

The base salary range for this position is $200,000 - $250,000 per year, depending on experience, skills, qualifications, and location. This range represents our good faith estimate of the compensation for this role at the time of posting. Total compensation may also include equity in the form of stock options.
