Founding software engineer 2025

About the position

Besty is building the AI brain for the $120B hotel and short-term rental industry. In less than two years, we've shipped a product loved by hundreds of paying hosts, achieving a 30% month-over-month revenue growth. We have raised over $4M from prominent investors, including the heads of the Stanford and Berkeley AI labs, and those behind Discord, Fastly, Hugging Face, Covariant, and Replicate. As one of our first five engineering hires, you will have the opportunity to shape the culture of the company for years to come.

Responsibilities

• Stand up new PMS integrations and latency/uptime targets as we scale from thousands to millions of API calls per day
• Pair with customers to surface pain points and ship fixes in hours
• Prototype AI workflows that automate messaging, dynamic pricing, and ops for hosts

Requirements

• You've built impressive solo or side projects
• Hungry, curious, and comfortable with minimal structure - maybe you've founded (or plan to found) something yourself
• You bias for shipping: fast feedback, tight loops
• Strong fundamentals in at least one backend language (TypeScript, Go, Rust, Python, etc.) and willingness to learn the rest fast
• Thrive in high-intensity environments

Benefits

• High ownership - direct line to product decisions & customers
• Ideal experience to found your own company or lead an engineering team
• Competitive equity and salary + full benefits
• One-on-one mentorship from Aarlo Stone Fish (20 years building & scaling SaaS)
• Fully in-person office in Flatiron, Manhattan
