You build the platform everything runs on: accounts, billing, provisioning orchestration, usage metering and the public API. If it's load-bearing, you probably built it.
What you'll do
- Design and build core services: identity, billing/metering, eSIM and number provisioning orchestration.
- Own the public REST API contract that the dashboard, SDKs, CLI and MCP server all consume.
- Build for multi-supplier resilience: idempotent provisioning, retries, reconciliation.
- Set the bar on security: auth, secrets handling, audit trails, least privilege.
- Keep it boring in production: observability, runbooks, sane deploys.
What you bring
- Production backend experience with distributed systems that handle money or regulated resources.
- Strong API design instincts and opinions about versioning.
- Postgres (or similar) fluency; you think in transactions.
- You've been paged, and you made sure it happened less afterward.
Nice to have
- Cloudflare Workers, payment integrations, or telecom/numbering domain experience.
