Job description

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.

Requirements

• 3+ years of backend TypeScript/Node in production — services, APIs, and async workflows, not just scripts.
• Payments or billing experience strongly preferred — subscriptions, webhooks, PSP integrations (Stripe, PayPal, Adyen, or similar), or other financial-correctness domains (ledgers, lending, e-commerce checkout).
• Postgres fluency — schema design and queries you'd defend in review.
• Willingness to learn Go — some of the platform lives in Go services; you don't need it on day one, but you need to want it.
• Testing-minded by instinct — you write the test alongside the code.
• AI-native workflow — you use AI-assisted engineering tools as part of your craft. Expected, not optional.
• Strong written and spoken English and availability on US business hours
