AI & Data

People who have put models into production, not just notebooks.

01

Model lifecycle

  • Data
  • Features
  • Training
  • Evaluation
  • Serving
  • Monitoring
  • Governance

Most AI briefs describe training. Most AI failures happen after serving.

The gap is rarely modelling ability. It is the number of people who have taken a model to production, watched it drift, and defended its decisions to a risk committee.

02

What we understand

  • Research vs applied vs platform
  • Feature stores & drift
  • Training/serving skew
  • LLM retrieval & guardrails
  • Evaluation harnesses
  • Fraud & risk decisioning
  • Model explainability
  • Data lineage & contracts
03

What we screen for

Has anything they built reached production?

We ask for one specific model or system in live use, its evaluation approach, and what degraded over time. Notebook work and production experience look identical on paper.

Evaluation discipline

For LLM roles we probe how they measured quality beyond vibes — datasets, offline evaluation, human review, regression detection on prompt or model changes.

Explainability where required

In credit, fraud and financial decisioning, a model that cannot be explained cannot be deployed. We screen for candidates who have worked inside that constraint.

FAQ

Frequently asked

Do you recruit AI talent outside financial services?

Yes — AI infrastructure, enterprise AI and data-intensive products generally. Our strongest coverage is where AI meets finance: fraud, risk, decisioning and compliance automation.

ML engineer or applied AI engineer?

An ML engineer trains, evaluates and deploys models. An applied AI engineer builds products on existing models — retrieval, orchestration, evaluation, guardrails. Briefs routinely conflate the two, and separating them is usually the single biggest improvement to a shortlist.
