Member of Technical Staff: Full-stack

Monk•New York City, NY

About The Position

Monk is an AI-native accounts receivable (AR) platform for B2B companies, helping businesses get paid fast. The AR stack is broken. Finance teams still chase payments with spreadsheets, reconcile AR in spreadsheets and use software that was built a decade ago. We think this is one of the largest, most ignored problems in B2B software. Trillions of dollars sit in outstanding invoices and the tools to unlock cashflow are stuck in the past. We are rebuilding Monk with AI, speed, and real craftsmanship. We are already doing this for over $1B of accounts receivables. We are backed by leading investors and our founders bring significant experience to our company. We are early, the upside is enormous, and the hardest, but also the most rewarding work is ahead of us.

Requirements

6+ years of production-level experience shipping full-stack products
Deep TypeScript fluency across backend and frontend
Strong product judgement and obsession, you make sound product decisions autonomously.
Experience with modern web infrastructure: Next.js, Vercel, Supabase, or comparable tools
Owner. You do not wait for specs. You figure out what needs to be built and go build it
Extreme drive and a track record of getting things into production, repeatedly, at high quality. You set the standard for code quality and you hold others to it
AI-native. You default to using AI to move faster. You see it as a multiplier, not a novelty
Excited to build in person in Flatiron, NYC

Responsibilities

Own an outcome: Design and ship agentic workflows end to end, from database schema to API to UI
Ship products and talk to customers: From the first line of code to conversations with the customers who use it. Use feedback directly to shape what you ship next. You do not rely on PMs
Set the standard for Agentic UX: Invent interaction patterns for how finance teams work alongside agents. This is a new world with no established best practice. You will pioneer the new bar for this industry
Defy technical limitations: We are an applied AI company where the outcome of your work determines our customer’s business outcome (cashflow). You will spend your time reinventing what it means to be reliable and accurate in an agentic world to get paid fast
Move fast across product areas: Ship across our web, backend, external connector products. Be a relentless force that solves problems fast and with technical and product craft
