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.
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.
Listening before modeling

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.
