Founding Full Stack Engineer
Location: New York City
Stage: Series A
Compensation: Competitive Salary + Meaningful Equity
We’re partnering with a fast-growing AI startup building infrastructure to automate accounts receivable workflows — tackling a massive global problem with trillions tied up in unpaid invoices every year.
The founding team has previously built and scaled a company to $50M+ in revenue and successfully exited. They’re now building an AI-native platform leveraging LLMs in deeply practical, workflow-heavy environments — not just surface-level AI features.
They’re looking for a Founding Full Stack Engineer to help architect and build the core platform as they scale following their Series A.
What You’ll Do:
- Build and scale the foundation of a high-impact AI product
- Own the full stack across backend systems, APIs, and frontend experiences
- Design complex workflow infrastructure powered by LLMs
- Work closely with founders on technical direction and product strategy
- Help establish engineering culture, standards, and architecture
- Ship quickly in a high-ownership, fast-moving environment
What They’re Looking For:
- Strong full stack engineering background
- Experience building and shipping production-grade products
- Ability to thrive in ambiguity and move quickly
- Strong product sense and ownership mentality
- Comfortable operating across frontend, backend, and infrastructure
- Interest in applied AI/LLM products and workflow automation
Why Join:
- High ownership and influence on product and technical direction
- Meaningful equity upside
- Opportunity to help shape engineering culture during a key growth stage
- Proven founding team with prior startup success and exits
- Fast execution environment with strong builder culture
- Ability to work on real-world AI applications solving large-scale operational problems
This is an ideal opportunity for someone who enjoys building in high-growth environments, wants significant impact, and thrives in fast-moving startup teams.
