🚀 Fractional CTO / Technical Advisor

🚀 Fractional CTO / Technical Advisor — Stealth GenAI Startup

_Equity‑first · Prague‑preferred · Co‑Founder Path_

We’re a stealth‑mode team quietly re‑imagining how people interact with large language models. If you’ve taken an AI idea from blank repo to Series A and love mentoring engineers in short async bursts, we’d love to meet you.

Engagement Tiers

Tier 1 — Mentor (≈1–3 h / week, mostly async) : Daily Slack check‑ins, design & PR reviews, technical sign‑off.

Tier 2 — Builder (≈3–10 h / week, weekly touch‑points) : Deeper architecture work, pair sessions, roadmap co‑ownership.

Tier 3 — Partner (10 h + / week, high‑touch) : Strategic leadership, investor calls, hiring, potential Co‑Founder or long‑term advisor/board member.

_(Tier 1 and 2 equity defined and discussed if selected — the more you lean in, the more upside.)_

What You Will Do

• Be online daily at 15:00 CET to review Slack questions (async).
• Act as fractional CTO & technical sounding board — advise on architecture, review Epics, tasks & PRs.
• Shape the roadmap — balance features vs. tech‑debt with the founder & senior advisors.
• Mentor — level‑up our engineers on GenAI best practices and help interview early hires.

Why This Is Interesting

• Greenfield architecture — absolutely no legacy baggage.
• LLM UX on the edge of what’s possible today.
• Hands‑on guidance — provide prompt‑engineering tips and MLOps advice.
• Clear path to Co‑Founder for builders who lean in.

You Might Be a Fit If You…

• Built & led an engineering org from first dev to at least Series A (≈0–30 people).
• Raised capital (founder, CTO, or key participant) and speak fluently with investors.
• Shipped AI/LLM‑powered products in production — bonus for local‑models or streaming systems.
• Full‑stack fluency: TypeScript/React, Python, LLM‑ops, deployment, and cloud/edge infra.
• Great async communicator who can unblock a team quickly over Slack/GitHub.
• Based in Prague/CZ or comfortable working CET hours.
