Monk is an AI-native accounts receivable platform for B2B companies, helping businesses get paid faster. The AR market is massive and underserved—trillions of dollars sit in outstanding invoices managed with outdated tools. Monk is rebuilding this space with AI, speed, and craftsmanship, already processing over $1B in AR and backed by leading investors.
As the first Sales Engineer at Monk, you will be the technical bridge between enterprise customers and the product. You'll establish partnerships with large, complex finance organizations, acting as the technical subject matter expert to design solutions that address their specific needs and integrations.
Key responsibilities include: assessing customer requirements and determining Monk's fit across use-cases, ROI, and technical capability; working hands-on with implementation teams to get enterprise customers live; prototyping and shipping agentic and financial products with enterprise clients; tailoring proof-of-concepts to prospects' real AR workflows (collections, cash application, deductions, disputes, integration systems); and identifying new products to help acquire business and scale with customer needs.
You'll move between deep customer workflow analysis and building novel agentic experiences. You'll be the customer's voice internally, relentless in creativity, and obsessed with shipping elegant technical solutions and scalable processes.
Required: 5+ years shipping production full-stack products; deep TypeScript fluency; product obsession with focus on gorgeous, intuitive, performant UX; customer-centric mindset; experience with modern web infrastructure (Next.js, Vercel, Supabase, or comparable); autonomous ownership; AI-native approach; comfort with ambiguity and non-deterministic systems; and willingness to build in-person in Flatiron, NYC.
Monk values ownership and craft, speed and urgency, and radical clarity. The company is early-stage with enormous upside, offering competitive salary, meaningful equity, medical/dental/vision, flexible PTO, dinner stipend, and a beautiful Flatiron office. Founders are experienced (ex-finance, previous exits) and committed to helping you develop founder-level skills.
