Affiniti - Backend / Data Engineer
Requirements
• 3+ years of production engineering experience across backend, infrastructure, or data. Early-stage startup experience strongly preferred. • 3+ years of production engineering experience across backend, infrastructure, or data. • Hands-on infrastructure depth. You've run production systems on GCP or another major cloud with Terraform and Kubernetes, and you have real opinions about how they should be set up. • Hands-on infrastructure depth. • You've scaled Postgres in production. You know what breaks as tables, traffic, and transaction volume grow, and how to fix it before customers notice. • You've scaled Postgres in production. • Real data engineering chops. You've built pipelines and data models other teams depend on, and you care whether the numbers are right. • Real data engineering chops. • A real backend engineer, too. Deep fluency in TypeScript and Node.js, and comfortable shipping product features, not just platform work. • A real backend engineer, too. • You know how to build with AI, not just use it. Tools like Claude Code, Codex, and other coding agents are a core part of your engineering workflow, and you know how to use them to dramatically increase your speed and output without outsourcing technical judgment. • You know how to build with AI, not just use it. • Speed without the debt. You move fast without leaving behind the kind of infrastructure mess that makes a platform painful six months later. • Speed without the debt. • High ownership. You take problems as your own and see them through — the mark of the people who thrive here. • High ownership. • Work Authorization • Work Authorization • Candidates must be currently authorized to work in their respective country. For this role, we are considering U.S. candidates who are U.S. citizens, U.S. lawful permanent residents (Green Card holders), or individuals who otherwise currently hold valid authorization to work in the United States. • For Canadian candidates, we are considering Canadian citizens, Canadian permanent residents, or individuals who otherwise currently hold valid authorization to work in Canada. • Equal Opportunity Employment
Responsibilities
• Own the infrastructure our product runs on. GCP, Terraform, Kubernetes, CI/CD, and the foundational decisions that determine how the platform scales, deploys, and stays up. • Own the infrastructure our product runs on. • Scale Postgres as we grow. Schema design, query performance, indexing, partitioning, replication, and migrations that never take the product down. • Scale Postgres as we grow. • Build the data pipelines the business runs on. Turn messy financial data from banking partners, payment systems, and our own product into clean, trusted data for reporting, underwriting, and reconciliation. • Build the data pipelines the business runs on. • Drop into the backend when it counts. Build APIs, ship features, and trace a bug from the database to the customer without waiting on anyone. • Drop into the backend when it counts. • Obsess over the details that separate systems that work from systems customers can trust: data integrity, uptime, failure modes, cost, and the edge cases most engineers skip. • Obsess over the details • Make reliability a habit, not a fire drill. Monitoring, alerting, incident response, and the fixes that stop the same problem from happening twice. • Make reliability a habit, not a fire drill.
Benefits
• $150K – $250K • Offers Equity • Reimbursed Relocation, Free Lunch and Dinner (In NYC), Paid Technology Equipment Set Up, Health, Dental, and Vision Insurance Fully Paid • There is an enormous gap between the technology built in Silicon Valley and what the average small business owner in America can actually get their hands on. The pharmacist in rural Louisiana. The auto dealer in the Midwest. The vet clinic owner who has done their books the same way for twenty years. They run the businesses that hold American communities together, and the software serving them has never reflected how much they matter. • Affiniti is closing that gap. We're building the financial operating system for small businesses across America, and the infrastructure and data underneath it are the foundation. Every pipeline you build, every query you speed up, every system that stays up when it matters is money moving reliably for the people who needed it most and never got it. • If you want to build the systems everything else stands on, this is that opportunity. • Location • NYC (in office), Canada (remote) • TypeScript, Node.js, Postgres, GCP, Terraform, and Kubernetes
