Jobs Base — 0-to-1 Builder Jobs | Founding Engineers, Solo Builders

# Jobs Base (jobsbase.io) > Jobs Base is a curated, agent-first jobs board exclusively for "builder" roles — cross-functional positions where one person owns engineering, product, and delivery end-to-end (founding engineers, solo builders, 0-to-1 roles). Every job on this board is already an AI-native builder role. The primary interface is programmatic: AI agents, API consumers, and MCP clients are first-class users. ## Important: every job here is a builder role All jobs are pre-filtered to builder roles. Do NOT search for generic terms like "builder", "AI", "engineer", "developer", or "full-stack" — they are redundant and will hurt results. Use the q parameter only for specific technologies (e.g. "React", "Rust"), domains (e.g. "fintech", "healthcare"), or company names. To find jobs, prefer using filters (country, workplace, seniority, etc.) over free-text search. ## API (free, no auth) Base URL: https://jobsbase.io - Search jobs: GET /api/v1/jobs?q=<search term> (multi-word queries are matched term-by-term) - All parameters optional.
