Backend Engineer - Payments

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
