Job summary

Anthropic seeks to centralize its finance data and build a scalable, auditable platform. You will craft an accounting engine that posts every event exactly once, with replay and backfill, serving Claude-related finance workflows and external vendors.

You’ll collaborate with Billing, Compute, Infra, and internal audit to translate requirements into robust, scalable designs while maintaining strong data integrity and governance.

Qualifications

• Backend engineering in a statically typed language such as Go, Java or Rust, or Python at scale.
• Experience designing and running high-volume, event-driven systems with idempotent processing, replay and backfill.
• Experience designing relational data models and writing SQL for complex, versioned data.
• Experience designing APIs, SDKs and service-to-service integrations used by other teams.
• Experience building systems with auditability, access control or compliance requirements.
• Experience turning requirements from non-engineering partners into technical designs.
• Strong written and verbal communication, including design docs.

Responsibilities

• 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.
