Reap is a fintech company providing borderless, stablecoin-enabled financial infrastructure for businesses. It offers business accounts (Reap Direct), Visa corporate cards with fiat and stablecoin repayment, cross-border payments powered by stablecoins, expense management for multi-currency treasuries, and embedded finance APIs including card issuing and payment APIs to automate global fiat payouts and enable stablecoin-native finance.

📋 Description

• Embed with engineering teams across Reap to build and integrate agentic payment capabilities into their systems • Own agentic features end-to-end across team boundaries: design the flow, build it where it needs to live, and operate it in production • Build backend services in Node.js / TypeScript (NestJS or Elysia) for high-performance APIs and async jobs • Work with AWS cloud-native services (Lambda, SQS, EventBridge, Aurora, S3, CloudWatch) for scalable, resilient architectures • Turn the agentic payments roadmap into shipped infrastructure • Collaborate directly with product, founders, and the host team's engineers • Leverage AI tools and modern development practices to move fast across multiple systems

🎯 Requirements

• 5-8+ years of professional backend engineering experience • A track record of dropping into unfamiliar codebases and shipping quickly • Deep expertise with Node.js and TypeScript, including RESTful API design and async job patterns • Strong product sense — ability to take a capability from idea to production without a detailed spec handed to you • Proven hands-on experience with AWS cloud services (Lambda, SQS, Aurora, CloudWatch, Secrets Manager, etc.) • Strong SQL fundamentals and experience with relational databases • Familiarity with event-driven and serverless architectures • Low ego and high adaptability • Clear communication and the ability to work autonomously in a fully remote, async team

🏖️ Benefits

• A high-impact role in a rapidly growing fintech startup • Flexible remote work environment with a global, collaborative team • Insurance coverage after probation • Reap Card stipend • Use of AI tools at work — and the space to learn, experiment, and grow with them • A culture of innovation, inclusion, and continuous learning
