Backend Engineer

Backend Engineer – Payments, TypeScript (Remote — LATAM)
About the Role

Our client processes serious subscription volume, and every renewal, plan change, and upgrade has to resolve into the right charge, the right credit, and the right event — every time — or a customer's order doesn't ship. You'll work in the backend of that system: subscription and renewal logic, credit ledgers, payment events, and webhook reliability.

The core stack is TypeScript (Google Cloud Functions) alongside Go services — you'll live mostly in TypeScript, and we'll teach you the Go you need. If you've built billing, checkout, or transaction systems in Node/TypeScript and sweat correctness, this role was written for you.
What You'll Do
- Build the money logic — subscription lifecycle, renewals, credits, and plan-change machinery that decides what a customer owes and what happens next.
- Guard the signal — every transaction emits a payment event that gates fulfillment; you'll treat event correctness and webhook reliability as the core of the job.
- Integrate the stack — work with payment processors and orchestration APIs, handling auth/capture, refunds, retries, and edge cases cleanly.
- Test like it's load-bearing — automated coverage written alongside the code; partial credits and multi-cycle renewals have too many edge cases for manual QA.
- Close the loop when needed — comfort touching the React surfaces your APIs feed is a plus; deep frontend work isn't the job.

The Stack
- Backend: TypeScript (Google Cloud Functions), Go, Temporal, Postgres
- Frontend: React, React Native (light touch)
- Infra/Observability: GCP, Datadog

Why This Role
- Own revenue-critical logic at real transaction volume — your work is impossible to miss.
- Small, senior team with direct access to product and leadership; no ticket-factory dynamics.
- Long-term, stable engagement through Maxana with direct integration into the client's team.
- Fully remote, LATAM-friendly hours.
