## Description

**About the Client**

Our client is one of the fastest-growing telehealth companies in the US — founded three years ago, now at eight-figure annual revenue, with partnerships spanning a major buy-now-pay-later provider and a household-name consumer fitness brand. Their payments platform processes every dollar of that growth.

**The Role**

You'll work on the backend of the payments platform: subscription and renewal logic, credits, and the payment events that release a customer's order. Correctness is the job — if the money logic or a webhook is wrong, product doesn't ship.

This is a hands-on engineering seat on a small team, not an architecture role.

**What You'll Do**

-   Build and maintain subscription, renewal, and credit logic in a TypeScript service
-   Own webhook reliability and payment-event correctness end to end
-   Work with payment processor and orchestration APIs — auth/capture, refunds, retries
-   Write automated tests alongside the code; partial credits and multi-cycle renewals have too many edge cases for manual QA
-   Occasional light React work where your APIs meet the checkout screens

## Requirements

### What We're Looking For

### Required

-   3–5 years of production backend TypeScript/Golang
-   Hands-on payments experience — you've worked on billing, subscriptions, checkout, PSP integrations (Stripe, Adyen, PagSeguro, Pix, or similar), or another system where money moved and had to be right
-   Postgres fluency
-   Comfort with event-driven systems and async processing
-   AI-assisted development as part of your normal workflow — expected, not a bonus
-   Strong written and spoken English
-   Availability during US business hours

### Nice to have

-   Go
-   GCP experience
-   React / React Native

## Benefits

-   Own revenue-critical logic at real transaction volume
-   Small senior team, direct access to product — no ticket factory
-   Long-term engagement through Maxana, paid in USD
-   Fully remote, LATAM-friendly hours
