About the Opportunity

Our client is an applied AI company building accounting software that automates financial workflows for entrepreneurs. Backed by $20M from OpenAI Startup Fund, General Catalyst, and Google Ventures , the team is scaling rapidly ahead of a planned Series A.

You will take ownership of backend services powering a modern AI-native product, working closely with Product, AI, and Operations teams in a fast-moving environment.

• Strong AWS or GCP infrastructure experience
• Practical CI/CD and deployment knowledge
• Solid observability and on-call practices
• Experience operating in fast-paced startup environments

Nice to Have

• Early-stage or scaling startup background
• Exposure to AI/ML-powered products
• Experience working without heavy PM structure
• Python or Ruby familiarity
• DevOps or Terraform experience
• Finance or accounting domain exposure

Why This Role Stands Out

• Backed by top-tier investors (OpenAI Startup Fund, GV, GC)
• Competitive salary plus meaningful equity
• High ownership in a scaling AI product company
