Senior Full Stack Engineer — Payments Infrastructure

Revley is building the operating system for the recurring economy, focusing on payments and tokenization infrastructure. They are seeking a Senior Full Stack Engineer to architect and scale their core platform, working closely with the founders and a senior engineering team to develop systems that manage real money transactions.

Responsibilities:

• Architect and ship multi-PSP payment routing across nine or more processors using strategy-pattern adapters in NestJS and TypeScript
• Build and maintain network tokenization flows and processor-agnostic token storage at PCI Level 1
• Design and implement subscription billing logic, including CIT checkout, MIT rebilling, authorization holds, captures, refunds, and voids
• Build webhook consumers for asynchronous processor events across all PSPs
• Make architectural decisions on database design, queueing, and observability, and document them clearly for the team
• Develop custom checkout experiences with Next.js on the frontend and NestJS on the backend, supporting credit card, Apple Pay, Google Pay, and PayPal
• Integrate with the Shopify Admin and Storefront APIs for order creation, selling plan management, and merchant onboarding
• Mentor engineers and contribute to engineering best practices

Requirements:

• Five or more years of professional software engineering experience, with a track record of shipping production systems end-to-end
• Strong backend engineering skills, with deep experience in Node.js and TypeScript (NestJS or a comparable framework)
• Demonstrated experience integrating payment processors such as Stripe, Adyen, NMI, Airwallex, or Braintree
• Working knowledge of payment tokenization, vaulting, and PCI compliance principles
• Experience with multi-PSP routing or orchestration architectures
• Deep experience with relational databases, including SQL and PostgreSQL
• Working knowledge of CIT versus MIT transaction flows, authorization and capture patterns, and webhook event handling
• Working proficiency with Next.js or a modern React framework (frontend depth is a plus, not a dealbreaker for strong backend engineers)
• Demonstrated ability to operate independently in early-stage or high-velocity environments
• Strong written and verbal communication skills
• Experience with network tokenization and tokenization platforms such as Basis Theory, Evervault, Spreedly, or VGS
• Experience designing distributed systems and event-driven architectures
• Experience with AWS services such as EventBridge, SQS, ECS, and CloudWatch
• Experience building checkout flows for Shopify, BigCommerce, WooCommerce, or custom platforms
• Experience with subscription billing platforms such as Stripe Billing, Recurly, or Chargebee
