What lands in your inbox instead of a resume pile
Other agencies send a PDF and a three-bullet vouch. Black-box AI tools hand you an arbitrary score no one can audit. Mosaic delivers an inspectable shortlist packet you can verify quote by quote—and lets you toggle to see the exact controls the candidate used before approving it.

How to read this evidence
Counts show which topics have source passages. Passages can describe successes, limitations, or work by other people. Quotes establish what was said, not independently verified accomplishments. Missing evidence is not a finding about ability. Review meaning and attribution before making a hiring decision.
Distributed incident diagnosis & mitigation
Why this matters and how it is evaluated
On-call engineers own primary triage across multi-region Postgres and Kubernetes services.
- Isolates contention or failure domain using telemetry before rolling restarts
- Applies bounded mitigation to stop customer impact while preserving forensic state
Weight: 40%
We saw p99 checkout latency jump from 90ms to 4.2s after a deploy, but CPU on the primary was flat. I pulled pg_stat_activity and caught an unindexed foreign-key cascade holding row locks across PgBouncer transaction pools, so we shed the async webhook worker pool first instead of failing over the primary.
Zero-downtime schema & state migrations
Why this matters and how it is evaluated
Role leads partitioning of a 14TB transactional ledger without maintenance windows.
- Sequences dual-writes, backfill throttling, and lock-timeout guards
- Defines deterministic cutover verification and instant read-path fallback
Weight: 35%
For the 12-terabyte ledger table, we ran an expand-and-contract migration over eleven days: dual-writing via a trigger with a 50ms lock_timeout guard, backfilling in 5,000-row keyset chunks gated on replication lag under 200ms, and keeping a feature-flagged read switch until checksum parity held for 48 hours.
Infrastructure RFC authorship & trade-off alignment
Why this matters and how it is evaluated
Requires aligning product and security teams on latency budgets and multi-tenant isolation.
- Documents rejected alternatives and concrete operational cost
Weight: 25%
In the multi-region failover RFC I explicitly priced the active-active option and recommended warm standby instead—showing product that synchronous cross-region writes would add 38ms to every card authorization for a recovery target we could meet with automated DNS + WAL replay in under 90 seconds.
How It Works
From open role to verified shortlist—with zero ATS integration
You don't need a new procurement cycle, seat rollout, or webhook plumbing to run a pilot.
Approve the role plan
A 10-minute intake turns your job description and must-haves into a version-pinned interview plan with explicit criteria, questions, location, and compensation band.
Structured voice interview (or live recruiter screen)
Candidates complete a role-specific AI voice interview on their schedule—or, on Human-Led Search, a live screen and pitch call with Josh Paul for passive senior roles.
Candidate review & explicit consent
Before anyone on your team sees a packet, the candidate reads the transcript and extracted spans, fixes any factual errors, reviews your role terms, and approves sharing with your company.
Inspect the shortlist link
You open a private shortlist link—no login or ATS integration required. Read criterion-by-criterion verbatim quotes in two minutes and advance who you want to meet.
Architecture & Guardrails
Built so every finding can be tested against its source
We separate extraction from judgment at the code level—and give candidates first-party ownership of their record.
1. Extract (Verbatim Only)
The model reads. It never judges.
At temperature 0, the model extracts candidate statements with character offsets and timestamps. It is forbidden from outputting a holistic pass/fail verdict or numeric rating.
2. Verify (Substring Resolution)
Confabulation is blocked mechanically.
Every extracted span must resolve to an exact substring of the interview transcript. Any span that fails resolution is discarded before evaluation. Missing coverage is labeled as unassessed, never as inability.
3. Candidate Control (Revision-Bound)
Nothing travels without candidate sign-off.
Candidates see their full packet, submit corrections that pause sharing until re-processed, confirm role-specific interest, and grant client-specific sharing tied to the exact packet revision.
What Mosaic refuses to build
No unconsented third-party web scraping in candidate packets. No automatic rejections or cross-slate black-box rankings. No voice tone, affect, or biometric inference.
