Why fractional

Full-time, freelance, or fractional — where each one fits.

01
Full-time design engineer
Full continuity — but a salary and headcount to carry before your product line justifies it.
~$113k/yr
CO design engineer · Glassdoor, 2025
02
Project freelancer
Flexible and low-commitment — but context resets each engagement, so continuity stays thin.
Resets each project
03
A dedicated block of my time
A full-timer's continuity, scaled to what you actually need — a 3-month commitment, not a hire.

What clients say

“Zach played an important role in developing our camper concept — working through the practical and technical challenges while also thinking along on the overall concept. He combines hands-on, practical experience with strong 3D and engineering skills, and he’s simply a good guy to work with.”
