**Location:** Phoenix, AZ
**Role:** Hardware Engineering
**Salary:** $169k – $208k/yr

**Posted:** 2026-08-16

> This role owns cooling, piping, and airflow systems for modular data center products from released drawings through rate production. The engineer works hands-on on the Phoenix manufacturing floor, leading first-article reviews, pressure tests, nonconformance disposition, and controlled design revisions.

## Job Description

## Responsibilities
- Own the mechanical systems of the modular product—cooling, piping, and airflow—from released drawings through rate production.
- Work on the Phoenix manufacturing floor daily to identify piping and assembly issues at the station where they occur and disposition them immediately.
- Run first-article reviews, fit checks, and pressure tests in person as units come down the line.
- Answer mechanical RFIs from the floor and engineer fixes into controlled drawing revisions rather than leaving one-off deviations.
- Feed production learnings back into drawings, tolerances, and the BOM so issues do not recur.
- Support modular data center designs from released drawings through first article and rate production.
- Engineer cooling, piping, and airflow systems that build cleanly at the station, pass pressure tests, and perform reliably in the field.

## Requirements
- Hands-on experience engineering mechanical systems for complex physical products or modular construction.
- Experience working on a shop floor or production line and dispositioning nonconformances in real time.
- Experience supporting production launches of personally designed products through rate production.
- Ability to create drawings that build cleanly and resolve fabrication issues through drawing updates.
- Experience running first-article builds and pressure tests and tracing failures to drawings or processes.
- Ability to iterate quickly while maintaining configuration control and ensuring the line builds from the correct revision.

## Nice-to-haves
- Liquid cooling experience.
- Piping and pressure-testing experience.
- Sheet metal design.
- Strong design-for-manufacturing instincts.

## Compensation
- Salary range: $169,000–$208,000.
