ShortlistSample data

Press Build the shortlist, or paste a role, to watch the shortlist arrive: Core reads the sample role, mines and assays engineers, and builds a shortlist of three.

Four practices, built first.

  • Agentic AI

    Agentic AI and orchestration · LLM applications and retrieval (RAG) · Machine learning engineering and MLOps

  • Cloud

    Cloud architecture and migration · Platform engineering and SRE · DevOps and CI/CD · FinOps and cloud cost

  • Data

    Data engineering and pipelines · Data science and analytics · Database engineering and performance

  • Full-stack

    Full-stack · Backend · Frontend · API and integration engineering

The engineer you interviewed isn't always the one who turns up.

Staffing agencies sell résumés and disappear on day one. Consultancies sell decks and bill for the bench.

What the 16Psyke architect wrote

Strong on what this role is about: keeping a fleet of agents reliable when the tools underneath them are not. Designed the evaluation harness before the workflow, which is the right order. Pushed back on the premise, correctly.
