Summary
Senior Software Engineer — Payments Platform
Authorized to work without sponsorship
The Company
We are building a modern, API-first fintech platform in the heart of Austin. 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 lean, ambitious, and AI-native by design.
The Role
You are full stack, 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 Node.js backend services and REST APIs — versioned, contract-stable, and hardened
ACH payment workflows end-to-end — debits, credits, retries, failure handling, virtual account ledgering, and reconciliation
Event-driven services using AWS SQS and webhooks for reliable asynchronous processing
PostgreSQL schemas that support complex financial workflows with integrity under failure
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 runbooks, 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 — you are comfortable representing the product outside the codebase
What We Are Looking For
Must Have
6–7 years engineering experience with a strong backend focus
Production Node.js and REST API design
Solid PostgreSQL — schema design, query optimization, data integrity
AWS — Lambda, RDS, SQS, API Gateway, Secrets Manager
OpenAPI / Swagger documentation experience
Event-driven systems experience — queues, webhooks, retry and failure logic
CI/CD pipeline experience and automated deployment workflows
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
Strong Plus
ACH payment workflows and NACHA operating rules
Experience with Java, Spring frameworks, or similar enterprise backend frameworks
Regulated fintech compliance — audit logging, idempotency, SOC 2
NestJS or similar structured Node.js frameworks
AI-assisted development tools — Claude, GitHub Copilot, Cursor
Team lead experience with mentoring junior team members
