Key Responsibilities
- Design and build Billing's first Python layer: the bridge between product features and the existing PHP core.
- Define the patterns for service communication, orchestration, and how responsibility splits between Python and PHP.
- Build scalable, async services for high-load, latency-sensitive billing workflows: payments, invoicing, anti-fraud, and regulatory compliance.
- Own API contracts across systems, keeping them stable, backward-compatible, and clearly bounded.
- Identify functionality worth extracting from the PHP core into Python services where it improves performance or maintainability.
- Design for failure: retries, idempotency, consistency guarantees, and the observability to catch problems early.
- Set the testing strategy, CI/CD, and rollout practices this layer will run on, since you're the one building them from scratch.
- Mentor and set the technical bar for two mid-level engineers who join the team after you.
- Partner closely with Platform and Product to keep architecture grounded in real business needs, not just technical elegance.
- Help shape how Billing supports new products and ventures being built on top of it.
