Senior Product Engineer, Embedded Finance
เกี่ยวกับบทบาทนี้
We're looking for a Senior Product Engineer who's fluent in TypeScript, Node.js, and AWS, and thrives in fast-moving, product-focused engineering teams. You'll be building the next generation of Reap's embedded finance infrastructure — powering stablecoin-backed payments, credit, and card services for global businesses. This is a high-ownership role where engineers design features end-to-end: from writing the PRD, to architecting the solution, to shipping and operating it in production.
ความรับผิดชอบของงาน
Own features end-to-end: write the spec, design the solution, build it, and operate it in production.
Design, build, and maintain 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.
Manage data storage and synchronization, working with Postgres and Aurora.
Implement and maintain CI/CD pipelines with GitHub Actions.
Contribute to architecture decisions, code reviews, and security practices.
Collaborate directly with product and business stakeholders — no PM layer, no hand-holding.
Leverage AI tools and modern development practices to drive engineering velocity.
คุณสมบัติของงาน
5+ years of professional backend engineering experience.
Deep expertise with Node.js and TypeScript, including RESTful API design and async job patterns.
Strong product sense — ability to take end-to-end ownership of a feature from idea to production.
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.
Clear communication and ability to work autonomously in a fully remote, async team.
Demonstrated use of AI tools to boost development efficiency.
Nice to Have
Experience building B2B API-based platforms or infrastructure products.
Background in fintech, payments, or card issuing.
Curiosity about Web3, stablecoins, or the Web2 ↔ Web3 intersection.
Startup experience where you've worn multiple hats.
