Job 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
