The Company
We are building a modern, API-first fintech platform. Our product spans client-facing applications,
payment processing infrastructure, and a high-volume ACH and reconciliation engine operating in one
of the most compliance-sensitive domains in US financial services. We are not guessing at product-
market fit — we have deep domain expertise, enterprise clients going live, and a founding team that
has done this before. We are lean, ambitious, and AI-native by design.
The Role
You are full stack engineer but you live on the backend. You care deeply about what happens when a
payment fails, an API returns an unexpected response, or a queue backs up at 2am. You will
own the backend services, payment workflows, and event-driven systems that sit at the core of
our platform — and you will touch the frontend when the team needs it.
This is a high-intensity role at an early-stage company. This role will ask more of you than a
typical engineering job — systems need to stay up, deadlines are real, and the team is small.
What You Will Build
Production backend services and REST APIs — versioned, contract-stable, and
hardened
Experienced in Node.js, Express.js, Hapi, NestJS, REST APIs, GraphQL, Microservices,
WebSockets, Job scheduling
Frameworks & Libraries: React.js, Next.js, Express.js, Redux, Redux Toolkit, React Hook Form,
TanStack Query, Jest, Playwright, Yup Resolver
ACH payment workflows end-to-end — debits, credits, retries, failure handling, virtual
account ledgering, and reconciliation
Event-driven architecture & services using AWS SQS and web-hooks for reliable asynchronous
processing
PostgreSQL schemas that support complex financial workflows with integrity under failure
Experienced in cloud (AWS) & Dev-Ops
CI/CD contributions and test coverage that gives the team genuine confidence to ship
Internal React dashboards and operational tooling when needed
Design documentation, deployment run-books, and scalability notes that you write
because you are proud of the work — not because someone asked
You will occasionally work directly with customers to support integrations, troubleshoot live
workflows, and demonstrate platform capabilities
representing the product outside the codebase
What We Are Looking For
Must Have
6–7 years engineering experience with a strong backend focus
REST API, MicroServices archtecture & design
Node.js, Express.js, Hapi, NestJS, REST APIs, GraphQL, Microservices, WebSockets, Job
scheduling

OpenAPI / Swagger documentation experience
Event-driven systems experience — queues, web-hooks, retry and failure logic
CI/CD pipeline experience and automated deployment workflows
You obsess over API design, documentation, deployment, scalability, and observability
Cross-functional communicator — comfortable working directly with Product, QA,
DevOps, and business stakeholders
Agile practitioner — sprint planning, backlog grooming, and code reviews are second nature
End-to-end owner — you do not hand off, you follow through to production
Must be currently authorized to work in the United States without sponsorship

ACH payment workflows and NACHA operating rules
Wire, debit card, and real-time payment rail experience beyond ACH

This is not a fit for you if
You consider documentation someone else's job
You lose interest in a feature once it ships
You need a detailed spec before you start building
