New This Week
We're working with a leading foundational AI lab to find experienced software engineers with a banking and financial infrastructure background who can help train their latest language model on core financial systems engineering tasks.
We're looking for senior and staff engineers with 5+ years of experience building or maintaining the large-scale infrastructure that underpins financial institutions: core banking systems, settlement and clearing infrastructure, ledger systems, and the data pipelines that connect them. You have worked in environments where uptime is measured in fractions of a percent, where data integrity is non-negotiable, and where changes go through more scrutiny than almost anywhere else in software engineering.
You'll create, evaluate, and refine AI-generated work across core financial infrastructure engineering workflows: core banking system architecture, ledger and settlement system design, data pipeline and reconciliation design, high-availability system patterns for financial environments, and technical documentation for large-scale financial infrastructure.
Compensation: $105/hour
Commitment: Flexible, up to 20 hours per week (up to $2,100/week)
Location: Fully remote, work on your own schedule
Start date: March
