Fractional Principal Engineering

Your fractional
principal engineer.
Senior-led. AI-augmented.

Architecture leadership without the $250K+ headcount line. Senior expertise, parallel AI-augmented delivery, direct accountability — at a fraction of the cost of a full-time hire.

Why traditional hiring doesn't work at your stage

Hiring a principal engineer takes 4–6 months — and that's before your first architecture review. Your roadmap doesn't wait.
A senior engineer costs $200–350K fully loaded per year. Most early-stage companies need 20–40 hours a month, not 160.
Most contractors just execute what they're told. You're paying senior-level rates with no architectural ownership and no one accountable for the outcome.
The Coldsmoke approach

Senior architect oversight.
AI-augmented delivery.
Team velocity at fractional cost.

The fractional model works when the work itself is done differently. Research, scaffolding, documentation, and boilerplate that used to consume senior hours now run in parallel — freeing capacity for the architectural decisions and production-critical work that actually require 20 years of experience.

You get a single senior engineer who scopes the work, builds it, and owns it through handoff. Not a project manager with a bench of juniors. Not a staff aug contractor who disappears when the ticket closes. One person accountable for the architecture, the delivery, and the outcome.

Architectural ownership

Nick designs it, builds the critical path, and owns it through handoff. Architecture reviews, security decisions, and production changes stay with a senior engineer — not delegated down.

AI-augmented delivery

Parallel work streams handle boilerplate, documentation, and iteration cycles — compressing timelines without cutting corners. You pay for the senior judgment, not the hours generating scaffolding.

No handoff tax

Every engagement ends with your team fully able to operate the thing we built — runbooks, documentation, and a handoff call. No dependency on us continuing to exist for your infrastructure to function.
