The opportunity
Every dollar Anthropic earns and every dollar it spends on compute has to reach the books correctly, and the volume grows with Claude usage. That data comes from across the company and from partners: usage and billing, compute, infrastructure assets, leases.
What you'll do
Design and build the front door into finance and its governed contracts: APIs for apps and agents, an event bus for systems that publish, adapters for vendor apps and reports, data-quality gates, and processing that posts every event exactly once, with replay and backfill
Drive the build of the accounting ledger and engine: an append-only ledger with idempotent posting, a rules framework that turns business events into journal entries, translation into the ERP, and period locks
Design and build the SDKs and frameworks that finance apps and agents build on
Build controls into the platform as code: immutable audit trail, maker-checker, scoped access and segregation of duties
Build and run the production services that other engineering teams call in: real time, such as the tax and collections services in the billing flow, and own their reliability: uptime, latency, throughput and correctness targets agreed with those teams
Shape the platform’s technical direction: architecture, engineering standards and design reviews
