Job description

About Fin
Fin is a next-generation payments platform built for high-value, global, and instant transactions. We are a Series A-stage company backed by Sequoia, Circle, and other notable investors. Powered by stablecoins, Fin enables users and businesses to move millions of dollars in seconds - whether to other Fin users, directly into bank accounts, or across crypto rails. By combining the speed of crypto with the reliability and trust of traditional finance, Fin reimagines how money moves worldwide. If banks and payment products were reinvented today, they would look like Fin.
About the role
We are looking for a Senior Backend Engineer to own the core systems that make this work. You will design and build the services that move real money, integrate with payment partners and banks, and ensure the platform is secure, observable, and ready to scale to millions of transactions.
You will work closely with the CEO, CTO, and a small senior team, making foundational architectural decisions and shipping production systems quickly. This role is a fit if you enjoy wresting simplicity out of complex problems and care deeply about reliability and correctness in financial systems.
We value your time: our process focuses on practical system design and architectural discussions, not LeetCode grinding or unpaid take-home assignments.
What you will do
  • Design, build, and maintain core backend services that power global payments and account experiences.
  • Own key systems end to end, from data models and APIs to deployment and ongoing operations.
  • Integrate with payment processors, on and off ramps, banks, and compliance and identity providers.
  • Monitor, tune, and scale backend services while maintaining high availability and strong performance.
  • Define and champion backend engineering best practices, coding standards, and architectural patterns.
  • Build internal tools and automation that improve developer productivity and system reliability.
  • Set and guide technical direction for backend architecture with a clear view of business impact and scalability.
  • Review code, share knowledge, and help raise the bar for the rest of the engineering team.
  • Own our cloud infrastructure setup and deployment workflows in partnership with the rest of the team.
What you need to be successful
  • Deep experience with TypeScript and Node.js. We are mostly a TS shop with some pockets of Rust.
  • Strong experience designing and building scalable distributed backend systems.
  • Track record of owning critical backend infrastructure and making impactful architectural decisions.
  • Deep familiarity with cloud infrastructure, containerization, and infrastructure as code.
  • Experience building highly available systems with robust monitoring, logging, and alerting.
  • History of creating clean, well documented APIs and integrating complex external systems.
  • Ability to collaborate in a small, fast moving team while mentoring others.
  • Clear communication skills and comfort working with both technical and non technical partners.
Bonus points
  • Experience at early stage startups where you owned large parts of the backend.
  • Hands on experience with our stack or similar: Node.js and Typescript, AWS, Terraform, Kubernetes, Temporal (https://temporal.io) .
  • Background leading technical strategy for a growing product or platform.
  • Experience in payments, fintech, or cryptocurrency, especially working with stablecoins or settlement systems.
