Requirements
- 6+ years of professional software-engineering experience, with significant work on complex backend applications.
- Experience decomposing a monolith.
- A track record on systems where correctness is non-negotiable, and the habits that come with it: idempotency, reconciliation, reversible migrations, and safe cutovers.
- Proficiency in at least one backend language (Go, Rust, Python, etc.).
- Familiarity with cloud infrastructure (AWS or equivalent).
- Strong production ownership including on-call.
- Bonus: Experience with billing, payments, or metering systems, or usage-based pricing.
- Bonus: Experience modeling entitlements, quotas, or multi-tenant limits.
Responsibilities
- Design and build the systems that define our plans, pricing, entitlements, and limits, and expose them through our API.
- Decompose billing from our monolith into services that are correct, testable, and independently deployable.
- Own correctness end to end — usage metering, reconciliation, and the invoices and usage data customers see.
- Operate what you build: SLOs, alerting, on-call, and fixing root causes rather than repeating mitigations.
