L4 · The Director

AI-Native System Builder

You build the AI system for the project — not just the code.

You direct agents at a high level instead of typing routine. A spec becomes production in days. You build reusable harnesses, run parallel agents in worktrees, add evals to CI, and set the safety policy.

What this level looks like

• ▹You orchestrate 5–10 parallel agents in worktrees
• ▹Spec → feature in production in days, not weeks
• ▹Reusable skills / harness + evals in CI
• ▹Independent AI review on every meaningful PR; 5+ h autonomous runs

How to reach Level 5: AI Engineering Architect

• →Turn repeated problems into reusable skills / harnesses
• →Run 3–6 independent agent roles incl. reviewer & security
• →Add evals + acceptance loops to CI; route models by task
• →Set hooks / permissions: tests before commit, approval for prod
