FAQ

Should I include DORA metrics?+

Yes — DF + LT + MTTR + CFR are universal engineering-org signals.

How important is AI/ML strategy?+

Critical in 2026. LLM eval + partnerships + shipped features.

Multi-cloud vs single-cloud framing?+

Multi-cloud signals reliability maturity; single-cloud with named tier signals focus.

Should I list patents?+

Yes with count + assignment.

Prior IC required?+

Strongly preferred. Staff / Principal / research background signals technical bar.

How important is Glassdoor?+

Signal for eng-culture stewardship. 4.5+ is top decile.

Should I mention M&A integration?+

Yes — technical DD + retention + codebase integration.

Do I need a PhD?+

Not required. Common at AI-heavy companies; not a gate elsewhere.

External board roles worth listing?+

Yes if peer-level. Investor + advisor roles also count.

Founder-CTO vs hired-CTO framing?+

Distinct — founder = capital raised + product bets; hired = scaled org + platform + hiring.
