Careers

Small company, working engine, network in pilot.

Fourthuman builds Physical AI training data for humanoid and VLA models out of India. Two founders, one validated end-to-end annotation run published in full with its SHA-256, and a Capture Partner network in pilot. The first commissioned brief is ahead of us. If that reads as the interesting part rather than a warning, read on.

Before you read the roles

What you would actually be joining

Stated the same way we state it to buyers, because a candidate deserves the same numbers a Commissioning lab gets.

The engine

Works, and is small enough to hold in your head

One clip has gone end-to-end: ingestion, face redaction, 3D annotation against FH-Ego v1, QA, export. 1,843 frames, 16 action segments. You can read the output on the reference implementation page before you decide whether you want to work on it.

The network

In pilot: the half we are building now

Capture Partners will be paid from ₹229/hr by UPI on QA approval and will hold revocable consent per task. None of that is running yet: no payment provider is integrated and nobody has been paid. Standing the recruitment, device logistics and QA loop up is the work, not a solved problem you would be maintaining.

The commercial position

Where the company is

The first commissioned brief is ahead of us. We have no third-party attestation — not SOC 2, not ISO 27001 — and we compete instead on verifiable provenance and on capture at an Indian cost structure. We would rather you knew the standing before an interview than after one.

Roles

Open positions

Bangalore and remote. Each role opens a panel with the full requirements and the exact question we would like answered in your email.

Roles not loaded

This list is empty because the script that renders it did not run. Email careers@fourthhuman.com and ask.

Applying

How to apply

Applications go by email, to an address a person reads. That is deliberate: a form would put a parser between you and the two people making the decision.

CV upload: not available

Send your CV by email — this box takes no uploads. Write to careers@fourthhuman.com; a person reads it, not a parser.

What to send

A CV as a PDF, the role you are applying for in the subject line, and a short answer to that role's question; the panel for each role states it. Three paragraphs is plenty; we are reading for how you think, not for length.

What happens next

One of the two founders reads it, and any reply comes from that person rather than a tracking system. If you have not heard back within two weeks, replying to your own email is a reasonable thing to do.

How we interview

We do not ask for unpaid trial work, and we do not run take-home exercises longer than an evening. If a conversation gets that far, we will tell you what we are trying to learn from it.
