Senior Full-Stack Engineer

Department: Engineering

Location: San Francisco Bay Area

Employment Type: FullTime

We’re looking for a senior full stack engineer to help build the core systems behind AI teammates for finance. You’ll design and ship infrastructure that allows agents to initiate, execute, and complete real workflows across messy enterprise environments. This is not surface-level AI. You’ll be working on systems that combine reasoning, context, and action in production.

What you’ll do

• Design and build end-to-end systems that power intelligent, outcome-driven workflows

• Own features across the stack, from backend services to user-facing interfaces

• Integrate AI models into reliable, auditable production systems

• Work closely with product and customers to solve real finance and accounting problems

• Build for scale, security, and enterprise-grade reliability from day one

What we’re looking for

• 5+ years of full stack development experience

• Strong proficiency in Python

• Experience with modern cloud platforms (AWS, Azure, or GCP)

• Hands-on experience integrating AI/ML systems into applications

• Background in enterprise software architecture and distributed systems

Why Numos
You’ll be building systems that don’t just assist work, but actually get it done. The problems are complex, the expectations are high, and the impact is real.
