the noise problem

AI didn't fix hiring. It scaled the noise.

AI hiring tools scrape the same public data and repackage the keywords as a fit. Volume went up. Signal didn't. Upswell runs on live Git telemetry and peer attestations behind a double-blind trust layer: signal AI can't fabricate, and you never have to prove.

If you're hiring

You're not drowning in candidates. You're drowning in candidates AI qualified for you.

It scored the words. You still have to find out if the engineer behind them can ship.

If you're building

Your public work is training data for tools you never opted into.

Scraped, ranked on stars and followers, and repackaged into a “profile” that isn't yours. Nothing about you exists on Upswell until you put it there.

AWAITING ATTESTATION2 vouches requested
BACKGROUND

Seven years, two AI startups, both pre-Series A. I owned ML infra at both: data pipelines, training, eval, and serving. No separate platform team, so I built and ran all of it. Cut inference latency 9x on a team of three. Wrote the eval harness both companies still use to gate model releases. Before that, three years on a platform team doing on-call for other people's services.

WHAT I WANT

Looking for a small team where I can take on the full path from experiment to production. Most of the hard work happens after training: serving, evals, cost, and keeping it up, and that's the part I'm good at. Happy to be the person who handles it so the rest of the team can stay on the model. Staff level, remote, seed or Series A.

WHAT YOU'D OWN

We build the model training infra layer for next-gen ML pipelines, from data ingestion through low-latency serving. You'd own training infra, eval harnesses, and the serving pipeline from experiment to production. Third ML infra hire, reporting to the CTO. Scope is wide and a fair amount of the tooling is still half-built.

FIRST 90 DAYS

Own the eval harness end to end. Ship the first fine-tuned model to production. Define the serving SLA with the CTO, and help hire the next two infra engineers.

how it works

Filter by telemetry. Connect by intent.

For foundersFor builders

Describe the stack, not the job

Stack, repo scale, and codebase complexity in under two minutes.

01Intake

Connect Git, read-only

Pick which repos are visible. Your source never leaves your machine.

Skip the whole screening layer

No resume triage, no agency shortlists, no AI-assembled lists.

02Analysis

Your pass builds itself

Radar, code footprint, and execution metrics generate from live data.

Vetting you can audit

Commit velocity, architectural depth, and peer-verified history.

03Validation

Get credit for work under NDA

The Vouch Loop turns unshareable work into verified peer attestations.

Read the radar, not a bio

Drawn straight from Git telemetry. Nothing to take on faith.

04Discovery

Filter by team mission

Real engineering expectations, team culture, and 90-day roadmaps.

05 · MUTUAL MATCH

Mutual opt-in drops the double-blind shield.

Contact details unlock only when both sides opt in.

match % = overlap between the tags a builder selects and the tags on a role. plain arithmetic, no model, nothing scraped.
