# Mechanical Field Engineer, Capacity Delivery

**Company:** [Fluidstack](https://hotfix.jobs/companies/fluidstack)
**Location:** Austin, TX
**Role:** Hardware Engineering
**Salary:** $157k – $208k/yr
**Experience:** 5+ years
**Skills:** mechanical engineering, data center construction, industrial construction, field engineering, punch list management, liquid cooling, welding, pipefitting, commissioning, quality control
**Posted:** 2026-07-17

> Serve as the on-site mechanical engineering lead for high-speed data center builds, verifying installations, running punch processes, resolving field issues, and feeding lessons back into reference designs for gigawatt-scale AI compute infrastructure.

## Job Description

## Responsibilities
- Be the mechanical engineering presence on site: walk installs, catch deviations, and answer questions at the workface.
- Verify mechanical installation against design daily: supports, slopes, clearances, torque.
- Run the mechanical punch process so systems hand to commissioning complete, not merely close.
- Feed field reality back to design: what's buildable, what isn't, what should change.
- Engineer gigawatts from drawing to energized, in months not years.
- Own technical execution across every build: the drawings, the field questions, and the engineering calls that keep multiple concurrent gigawatt sites moving.
- Engineer data centers that go up in months, not years. At that pace rework is not an option: problems get caught on paper or they cost a data hall.
- Design it once, build it a hundred times. Every site's lessons roll into the reference design on the way to 50GW+, so each build starts ahead of the last.

## Requirements
- You've field-engineered mechanical scope on industrial or data center builds.
- You spot a wrong install from across the data hall.
- You document findings so contractors fix them without a fight.
- You live on site during the build and like it there.

## Nice-to-Haves
- Welding and pipefitting knowledge.
- Liquid cooling installs.
- Commissioning support.
- QC certifications.
