🏢 About Doco Engineering

Founded and led by Doug Pientak, a multi-disciplinary engineer with over 25 years of experience across electrical, mechanical, and PLC systems, Doco Engineering Inc. is a Northern California leader in automation and precision manufacturing.

What makes Doco unique is its combination of engineering expertise and hands-on CNC manufacturing. Doug’s background in Assembly Language, C programming, and advanced control systems allows Doco to evaluate projects from every angle — ensuring smarter designs, better performance, and long-term reliability.

The result: custom automation systems and precision-machined components that meet the highest standards of accuracy and quality.

🛠️ CNC Capabilities

Doco’s CNC division supports both high-volume production and one-off prototype work, using Haas machines with WPS probing systems to reduce setup times and deliver cost-effective precision. The team works heavily in Autodesk Fusion 360, performing mostly 2.5D programming and machining on complex, dynamic parts used in advanced automation builds.

Doco was recently recognized by Xometry for “Excellence in Manufacturing” — achieving 100% accuracy and 100% on-time delivery.

👥 Culture & Team

At Doco, engineering and manufacturing operate as one. The team describes itself as a family-like environment, where knowledge is shared and everyone contributes to progress.

A Master Machinist is onsite daily, providing mentorship and training for newer machinists looking to grow their skills. Whether you’re an experienced programmer or an up-and-coming operator, you’ll have the opportunity to learn, collaborate, and take pride in meaningful work that moves technology forward.

As founder Doug puts it:

“If it’s worth doing, it’s worth doing right.”
