About the Role

Astra is looking for a Staff Backend Engineer to shape the core of our financial platform, including our global ledger, orchestration layer, and customer-facing APIs. You’ll work closely with product, compliance, and operations to deliver reliable systems that move and reconcile millions of dollars every day.

What You'll Do

  • Design and own key backend systems, such as payments orchestration, ledger primitives, and internal operational flows
  • Help evolve our service architecture as we scale, including how we model financial state, manage auth, and handle retries
  • Write clean, well-tested Python code using Flask and GCP-managed services
  • Work closely with other engineers, product, and cross-functional teams to understand customer needs and deliver robust APIs and features
  • Contribute to our observability, reliability, and deployment workflows
  • Participate in code reviews, tech planning, and mentoring

What We're Looking For

  • 7+ years of experience building backend systems in production
  • Strong system design and architecture skills; you’ve designed services that scale and evolve
  • Expertise in Python and API design; experience with Flask or similar frameworks
  • Familiarity with distributed systems, asynchronous processing, and idempotency
  • A product-minded engineer who enjoys building platforms with real-world constraints like money, compliance, and reconciliation
  • Comfortable taking projects from idea to implementation with minimal oversight

Nice to Have

  • Experience with GCP, Terraform, payments/fintech, or event-driven architectures

Technical Stack

  • Languages/Frameworks: Python (Flask/FastAPI), TypeScript (React)
  • Infrastructure: GCP (App Engine, Pub/Sub, Cloud Tasks, BigQuery, Datastore, GCS)
  • Tooling: Terraform, GitHub Actions, CircleCI, Cloud Logging
  • Data: BigQuery, Datastore, GCS

Team & Environment

We’re a small, fast-moving team tackling hard problems in financial infrastructure. You’ll work closely with product, compliance, and operations.
