Hire from how engineers think, not how they rehearse.
Chiron is an AI-era technical screen and coding assessment built on real engineering work alongside Lyra, an AI pair. We measure their code, their reasoning, and how they direct the AI — and hand your team a reviewable recommendation.
A leetcode question tells you whether a candidate has seen a leetcode question. The work doesn't look like that anymore — so the screen shouldn't either. Chiron screens for how someone thinks, decides, and pushes back when the AI is wrong.
A real editor, a real spec, a real pair. No fishbowl.

Three independent signals. One natural session.
Evidence, not a verdict.
Every score expands to the quote, the diff, or the moment that produced it. The reviewer reads, considers, and decides. Chiron recommends; the human calls.
Caught both planted errors, and said why.
Rejected a patch that silently dropped the last record, then flagged a missing null guard unprompted twelve minutes later.

A pair, not a proctor.
Lyra reads as a calm, helpful colleague — a senior teammate the candidate has never met. Lyra drafts, reviews, and asks questions to understand their thinking. Disclosed up front: Lyra is also fallible, and reviewing that work is part of the job.
The spec changes mid-flight. Like it does at work.
Once per session the requirements shift — calmly. Lyra flags it, the brief updates with what changed, the candidate acknowledges and adapts. We score how they handle the pivot, not whether they flinch.
Already have an ATS? Chiron Screen drops into it. Don’t have one? Chiron Hire is the platform around it — pipeline, scheduling, offers and analytics.

Chiron is designed against NYC Local Law 144 and the EU AI Act from the foundations up — not retrofitted. Every dimension is auditable. Every recommendation is reviewed by a human.
