Calibratr is an AI-native embedded recruiting firm.

We embed full recruiting pods inside fast-scaling seed to Series B AI startups, with a focus on AI in healthcare, and run hiring end to end: sourcing, screening, calibration, and close.

We hire on proof of work, not resumes, and calibrate to a founders real bar instead of a keyword list.

Our stack pairs experienced recruiters with an AI-native sourcing and evaluation workflow, so a small team moves at the speed our clients need.

About the Role Own and scale Calibratrs sourcing function across every client engagement.

This is a player-coach role: you run high-bar searches yourself and build the team, tooling, and quality bar that let a small pod out-source firms ten times our size.

What youll own Set the hiring thesis for each role alongside the recruiter and hiring manager: the actual problem the role solves and where that person works today, not a mirror of the job description.

Run and oversee evidence-based sourcing across our client book, building shortlists against tight specs (stage, stack, geo) with candidate rationale a founder can act on.

Own our AI-native sourcing workflow (Claude, Exa, Ashby, AI sourcing tools) and keep improving it: search strings, scoring, dedup, and calibration loops against real client feedback.

Hold the quality bar: enforce proof-of-work scoring,



our client-exclusion and no-duplicate rules, and verbatim-source discipline so nothing goes out half-checked.

Hire, train, and QA a bench of contract sourcers, calibrate them fast, and keep the bar consistent across everyone.

Own the sourcing scoreboard: shortlist-to-screen-pass rate, volume, and turnaround per client, and report it weekly.

Youre a fit if Youve personally sourced senior and staff-level roles (engineering, AI/ML, GTM), not just run high-volume pipelines.

You can read a technical spec and tell the difference between worked somewhere that uses X and built the thing.

Youve managed or trained other sourcers and can hold a calibration bar across a team.

Youre fluent with AI-native sourcing tools, or you pick up new tools rapid and have real opinions about how to use them well.

You write clearly.

Your candidate rationale goes straight to founders.

You default to high agency: you unblock yourself, flag a bad spec early, and dont wait to be told.

Bonus Youve sourced in AI or healthcare talent markets (HIPAA/FHIR, clinical, applied AI and agents, MLE).

Youve built or heavily used LLM workflows for sourcing or candidate evaluation.

How we work: Remote-first, US hours.

Small team, direct access to founders, fast feedback.
