Head of Evaluations at a frontier model lab building general-purpose foundation models.

Head of Evaluations, reporting to the Head of Research. The Head of Evaluations runs one team across capability and safety evals on the lab's foundation models.

About the firm

Anonymised by default.

A frontier model lab building general-purpose foundation models. Around 130 staff, research-dense. The lab publishes evaluation research regularly, and the Head of Evaluations is one of the named authors.

We name a client on the mandate page only where the firm has approved publication. Where not named, the description above is intended to be enough for a senior candidate to recognise whether their pattern fits the brief.

The brief

What this seat exists to do.

Head of Evaluations, reporting to the Head of Research. The seat is one of four research area leads under the new Head of Research's structure.

Direct line management of around 12 evaluations researchers and engineers across two squads — capability evaluations and safety evaluations. Hiring three further senior researchers in the first nine months.

Owns the lab's pre-deployment evaluation programme for the next flagship model and the lab's engagement with the relevant AI Safety Institutes in the UK and US.

London-based, office-first three days per week. Travel to relevant policy convenings expected each quarter.

What we are assessing for

  • A current evaluations lead at a peer frontier lab, foundation lab, or AI Safety Institute; the candidate market for this seat is narrow and well-defined.
  • Comfort with the dual remit — capability evaluations are an engineering-led discipline, safety evaluations are research-led, and the seat owns both.
  • Publication credibility. The lab publishes on evaluations and the seat is the named voice for that publishing.
  • Patterns: a current evaluations lead from a peer frontier lab; a senior researcher from a major AI Safety Institute; an evaluations engineer from a foundation lab ready to step up.
The firm's read

Spectrum's read on this search.

The Head of Evaluations runs one team across capability and safety evals on the lab's foundation models. Capability work and safety work sit under the same head, on the same roadmap, with the same researchers. The role reports into the Head of Research, who has shaped it from the start and will be the day-one working relationship. Evaluations are part of what the lab publishes, so the work is visible externally as well as inside the research org.

— Peter Wood, Partner & Chief Strategy Officer
