Job Description:

This team designs intelligent, autonomous systems that eliminate financial operations for companies globally. We automate everything from bookkeeping and reconciliation to tax, payroll, forecasting, and document understanding: turning hours of work into seconds. The team blends deep research pedigree with proven industry experience. We operate with high standards, are tool-agnostic, and expect engineers to own problems end-to-end. We collaborate closely, push boundaries responsibly, and ship exceptional work quickly. You’ll solve unprecedented technical challenges using unique, end-to-end financial datasets no one else in the industry has.

Job Responsibility:

  • Design and operate distributed, event-driven systems that process high-volume, high-sensitivity financial data with strict correctness and latency guarantees
  • Build typed, production-grade APIs and services in Python (FastAPI + Pydantic) that power agentic workflows, AI copilots, and real-time financial infrastructure
  • Own data architecture end-to-end schema design, event models, ledger primitives, and storage layers optimized for auditability, traceability, and scale
  • Develop resilient infrastructure primitives (queues, retries, idempotency, observability, backpressure handling) that let teams ship fast without sacrificing reliability
  • Work at the intersection of systems + AI, building feedback loops where product data continuously improves models and models autonomously improve system behavior
  • Ship platform foundations, not one-off features internal frameworks, SDKs, and tooling that accelerate every engineer in the org
  • Partner closely with ML + product teams to productionize research-grade ideas into real customer-facing systems
  • Help define the architecture of an AI-native financial stack not bolting AI onto software, but designing software assuming AI is a first-class runtime

Requirements:

  • 5+ years backend experience with Python at scale
  • Deep knowledge of SQL/NoSQL database design
  • Experience with distributed systems, event-driven architectures, or microservices
  • Familiarity with GCP services (Pub/Sub, Cloud Run, Cloud SQL, BigQuery, KMS, etc.)
  • Strong grasp of security and compliance best practices
  • Passion for building the backend that powers intelligent products
What we offer:
  • Offers Equity
  • Offers Bonus
  • medical, dental, and vision insurance
  • a 401(k) plan
  • short-term and long-term disability
  • basic life insurance
  • well-being benefits
  • 20 paid days of vacation
  • 12 paid days of company holidays
