Mechanical Design Engineer, Mechanical Routing

Karman Industries•Los Angeles, CA

3d•$80,000 - $160,000•Onsite

About The Position

Karman Industries is seeking a Mechanical Design Engineer to own fluid routing for its Heat Processing Unit (HPU), a supercritical CO2 chiller system designed for large-scale data centers and AI factories. The role focuses on translating P&IDs into compact, serviceable, and buildable piping, tubing, and hose networks using Siemens NX Mechanical Routing. Routing decisions must account for flow, thermal growth, support loads, vibration, clearance, service access, assembly, and leak risk. The engineer will develop and maintain NX assemblies and routing libraries, release manufacturing drawings and documentation through Teamcenter, and design supports and restraints in coordination with analysis engineers. The role also follows designs through fabrication, prototype builds, testing, and model updates, while coordinating packaging with electrical routing and other disciplines. The position is based on-site in Gardena, California.

Requirements

Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related discipline.
At least 1 year of hands-on mechanical design or build experience; internships and engineering project teams count.
Expert-level Siemens NX skills, including large assemblies, WAVE and interpart linking, parametric modeling, and production drawings.
Hands-on experience with NX Mechanical Routing or tube and pipe routing in another 3D CAD tool.
Solid drawing and GD&T fundamentals (ASME Y14.5).
Strong hand-calculation fundamentals, including pressure drop, wall thickness, thermal expansion, and support loads.
Clear communication and the habit of keeping models, files, and documentation organized.

Nice To Haves

Teamcenter experience with revisions, BOMs, and change workflow.
NX Open, journaling, Python, or VBA experience to automate bend reports, BOMs, or drawing checks.
Tube and pipe fabrication knowledge, including bend limits, weld joint types, and flared, flareless, and welded fittings.
Experience with ASME B31.3, B31.1, or BPVC, and pipe stress or FEA tools such as CAESAR II, ANSYS, or NASTRAN.
Exposure to turbomachinery, heat exchangers, refrigeration, or supercritical and high-pressure working fluids.
Formula SAE, Baja SAE, rocketry, Design Build Fly, or similar project-team experience.

Responsibilities

Route piping, tubing, and hose in NX Mechanical Routing from P&IDs across skids, test stands, and turbomachinery interfaces, balancing flow, thermal growth, clearance, and service access.
Build and maintain robust NX assemblies using WAVE-linked routing spaces and reference sets.
Create and maintain routing libraries for tube, pipe, fittings, valves, and flanges, including correct stock, bend radii, and port definitions.
Release isometrics, bend tables, weld maps, and fully dimensioned drawings with GD&T through Teamcenter.
Design pipe supports, brackets, and restraints, and work with analysis engineers on ASME B31.3 flexibility and stress results.
Work with suppliers and technicians on tube bending, orbital welding, cleaning, and pressure testing to support first-build fit.
Support prototype builds, leak and proof testing, and instrumentation, and incorporate findings into the model.
Coordinate packaging with the electrical routing engineer and other disciplines in design reviews.
