Joshua’s Story

Joshua Raimond Portrait

Early Career

ANDIAL & Porsche Motorsports North America

Physics

UC Berkeley & Hasselgren Porsche Program

I’ve spent my career around racing engines, rocket engines, and mechanical systems built to survive high forces, extreme temperatures, and unforgiving environments—machines that have to work at their limits: on track, in test cells, and in orbit.

I started in motorsport at ANDIAL and Porsche Motorsports North America (PMNA), where I earned a reputation for endurance-race builds that were slow, meticulous, and faultless. After studying physics at UC Berkeley, I ran Hasselgren’s first Porsche race-engine program in its entirety, brought an AVL dyno online and ran every aspect of it, and calibrated Bosch Motorsport and Pectel ECUs while doing track support all across the U.S.

Pinnacle Engines was where I became an engineer. I arrived from physics and motorsport with a feel for machines but little formal grounding in mechanical design. What I found there was a masterclass in every dimension of the discipline.

I learned the clarity and craft of design from a former Cosworth engineer who became my mentor; I learned rigor in engineering calculations and the standards that give them meaning; I saw what ambition looks like in computational techniques and in the imagination of design. I was taught restraint—how easily one can go too far into analysis or the minutiae of an idea—and I learned honesty, the value of seeing things exactly as they are. As I grew, I started to see how easily convention masquerades as certainty, and I learned to question the designs most everyone else accepted without asking why.

My early years were spent in a culture where truth mattered more than ego. Designs were discussed warts and all, and mistakes were treated as data, not failures. That environment shaped the way I work today: open, empirical, and unafraid to question. Engineering, I learned, isn’t about defending an idea—it’s about revealing the truth the machine is trying to tell you.

The Philosophy

Engineering isn’t about defending an idea—it’s about revealing the truth the machine is trying to tell you.

When I transitioned to aerospace, the stakes changed, but the approach stayed the same: listen carefully, understand the real constraints, and design until the solution feels inevitable. Every successful project begins with empathy—listening to what people need, asking the questions that expose the unknowns, and making sure nothing important hides between the lines of the requirements.

Creativity comes when the boundaries close in: when space is tight, materials are limited, and every decision affects five others. The process becomes iterative—sketching, modeling, testing ideas quickly, proving them with simple calculations before committing to complexity.

At Commonwealth Fusion Systems, I replaced an over-complicated mirror assembly with a pure silicon-carbide design that resisted heat, ignored EM fields, and met review with a 3× safety margin.

Today, through cog design, I act as a fractional mechanical design team for clients who need reliable hardware under real loads. Empathy, curiosity, idealism, tenacity—applied to machines.

Most projects don’t fail because of a lack of intelligence or effort.They fail because too many things are treated as equally important.

Our work begins by helping teams identify what matters most, and what can safely recede into the background. That clarity is what allows complex systems to move forward without unnecessary risk or noise.

Our Approach

Finding balance in complexity.

Cog Design works as a fractional mechanical design team.

We partner with organizations building complex machines and systems, adapting our role to what the work actually requires.

Sometimes that means carrying an entire mechanical design scope from concept through prototype and test. Other times it means embedding within an existing team to provide senior-level insight at key moments.

In both cases, our role is the same:to help machines, and the people building them, find balance.

Joshua Raimond

The author has built a career around high-performance mechanical systems, beginning in motorsport at ANDIAL and Porsche Motorsports North America before studying physics at UC Berkeley. Through roles in race-engine development, running dyno programs, calibrating ECUs, and providing track support, they developed a hands-on feel for machines operating at their limits.

The pivotal transition to full engineering came at Pinnacle Engines, where a mentor from Cosworth instilled the discipline of rigorous design, honest calculation, and the intellectual courage to question conventions others accepted without scrutiny. That culture, where mistakes were treated as data and truth mattered more than ego, became the foundation of how they work.Carrying that mindset into aerospace, the author applies the same core approach: listen carefully, frame the problem honestly, and design iteratively until the solution feels inevitable.

They treat empathy as an engineering tool, exposing hidden requirements, understanding real constraints, and letting the physics guide the outcome rather than defending a preconceived idea. Notable work includes replacing an over-engineered mirror assembly at Commonwealth Fusion Systems with a clean silicon-carbide design that hit a 3× safety margin. Today, through their firm cog design, they serve as a fractional mechanical design team for clients who need hardware that performs reliably under real-world loads.
