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
