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
