I take hardware products from concept to production.

Twenty-five years across mechanical, electronic and software products — industrial design, project management, design for manufacturing, sourcing and contract manufacturing. I co-founded Olinthus, and I take on outside work for teams that need it.

Available for fractional, project and contract work

About

Charles Etienne
Charles Etienne Co-Founder, Olinthus · Los Angeles

Born in Montreal, raised bilingual, and a jazz musician in New York before Los Angeles and a physics degree at CSUN. I have spent the years since making things that get manufactured.

At Strymon I started as a mechanical designer in 2011 and finished as project manager, running a 17-product line as part of a small, fast-growing team. In between I ran industrial design for 15+ product lines and helped deploy the company’s product data management system.

In 2022 I was CTO of a French audio company, where I built the product strategy, roadmap and specifications, and reformed how development actually ran.

In 2023 I co-founded Olinthus with Ethan Tufts. We design and build the world’s smallest effects pedals. I take our products from concept through production — CAD, sourcing, compliance and contract manufacturing.

I also run agentic-AI workflows in our own development: LLM agents drive KiCad and FreeCAD through MCP and draft purchase orders, which I review and approve before anything reaches a supplier. It is genuinely useful and genuinely unfinished.

I work in English and French, and I hold US, Canadian and EU (Belgian) citizenship.

Selected work

Every one of these started as a question from a client. Sketches, CAD, iterations, then the thing itself.

01

Can you fit a real pedal into something this small?

Olinthus, 2023 onward. Sketch, CAD, board layout, tooling and a contract manufacturer — the whole path from a drawing on paper to trays coming off an assembly line.

  • Design for manufacturing
  • Sourcing
  • Hand sketching
  • CAD
  • PCB layout
  • Contract manufacturing
02

Can you give a guitar pedal a backstory?

An illustrated world for the product — characters, a city, and a story told across panels and animation. I directed it; the illustration and animation were done by others.

Nobody asked for these. I have a passion for making things I find useful around the house — plywood, glue and drywall screws seem to be my medium.

  • Cardboard
  • SolidWorks
  • Blender
