Payments Engineer

The Team You Will Join
The mission of the Payments group at Mercor is to be the financial and commercial backbone of the company.

We ensure that:

Money moves deterministically and reliably at scale
Failures are surfaced proactively, not reactively
Ledger, payout, and settlement systems are observable end-to-end
Root causes are fixed, not patched
Automation replaces manual intervention wherever possible
We operate at the intersection of Engineering, Finance, Product, Ops, and Fraud. Our mandate is to transform payments from manual orchestration into resilient financial infrastructure.

The Role
This role exists to help build the financial backbone that supports the next 1000x. We are looking for a senior engineer to help harden and scale Mercor’s payments platform.

You will work on:

Flow-level observability across payout → settlement → reconciliation
Reliability engineering for distributed payment systems
Instrumentation and monitoring of financial primitives (ledger, payout orchestration, settlement ingestion)
Automation to eliminate manual treasury and payout workflows
Root-cause driven system redesign
