Full Stack Engineer with Payment Processing
Job Description
About the company:
Revley operates at the intersection of SaaS, fintech, and performance-driven eCommerce.
We're a New York-based startup building a subscription and payment processing platform for e-commerce businesses.
Our system handles real transactions, recurring billing, and complex payment workflows across multiple payment gateways.
As an early-stage company, every engineering decision matters. You'll work on a small, focused team where your contributions have a direct impact on product direction and customer success.
What We Want You To Do
- Ship key product features: Build new subscription management capabilities-lifecycle state transitions, billing logic, payment method handling. Features you ship will go directly to production
- Refactor and improve existing systems: Identify bottlenecks, improve code quality, and enhance our payment processing flows. We'll teach you how to read complex codebases and make them better
- Debug production issues: Investigate payment failures, trace issues through logs and databases, and implement fixes. Learn systematic debugging in distributed systems
- Design and implement database changes: Write migrations, design schemas for new features, and optimize queries for financial data accuracy
- Build and extend APIs: Develop REST endpoints using NestJS, implement business logic, and ensure type safety across the stack
- Write comprehensive tests: Add test coverage for new features and existing code. Learn testing strategies that matter for production systems
Requirements
You're Perfect If You Have/Are…
• 3+ years of professional experience building production web applications with NestJS, , and TypeScript
• Hands-on experience working with PostgreSQL based databases (Supabase is a strong plus) including schema design, migrations, and performance optimization
• Experience deploying and operating production systems using Vercel and AWS
• Direct experience integrating with eCommerce platforms (Shopify) and at least one payment processor such as Stripe, Adyen, Airwallex, or NMI in real production environments
• Proven experience building and maintaining payment flows (billing logic, payment method handling, retries, webhooks, and failure handling)
• Experience designing and consuming REST APIs with strong typing and clear contracts across services
• Comfort working with production logs, databases, and monitoring tools to debug payment and financial issues
• Experience writing meaningful automated tests for critical business logic (especially around billing and payments)
• Strong understanding of data integrity, idempotency, and error handling in financial systems
Nice to have:
• Experience with AWS EventBridge, SQS, ECS, or similar event and messaging infrastructure
• Familiarity with containerized environments and orchestration (Docker, Kubernetes)
• Exposure to PCI DSS and SOC 2 compliance considerations in payment or fintech systems
What we explicitly look for:
• You have used these tools and systems in real production environments, not just side projects or tutorials
• You have shipped payment-related features that real users rely on
• You understand the operational and reliability requirements of financial systems
Benefits
• Fully remote role with EST working hours
• High-impact position with real ownership and autonomy
• Fast-growing SaaS and fintech environment with real problems to solve
• Clear growth path as the company scales
• Performance-based bonuses and career development opportunities
