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 ### 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 - 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
