Job Title: Founding Engineer Company: Butterbase (butterbase.ai) Location: San Francisco, CA / Seattle, WA (Remote, US) Employment Type: Full-time Experience Level: Mid-level (3-4 years) Salary: $100,000 - $150,000/year

About Butterbase Butterbase (butterbase.ai) is an AI-native full-stack app platform providing a Postgres database, serverless functions, auth, storage, an AI gateway, and one-click deploys. The platform is built so both humans and AI agents can ship production apps fast. We are a small founding team with a live product, real users, and a growing recipes ecosystem.

The Role You will be our founding engineer, the first engineering hire, working directly with the founders. You will own core platform work end-to-end: design it, build it, ship it, and operate it.

Responsibilities

• Ship core platform features across the stack (TypeScript, Node, Postgres).
• Build and harden the AI gateway and agent-facing APIs (LLM integrations, MCP).
• Own reliability, performance, and developer experience of the platform.
• Talk to users, turn feedback into product, and help set the engineering culture.

Requirements

• 3+ years building production full-stack systems (TypeScript/Node + Postgres or similar).
• Experience shipping real products end-to-end and comfort owning ambiguity.
• Hands-on experience with LLM APIs or agent tooling is a strong plus.
• US-based.
• Startup speed and extreme ownership.

Compensation & Benefits

• $100K-$150K base salary plus meaningful founding equity.
• Remote work (US).
• Founder-level ownership from day one.
• A seat at the table while the platform and company take shape.
