Job description

QA slows the world down. Flaky tests kill trust, stall releases, and bleed engineering velocity.

Duku AI is ending that era.

We’re building autonomous agents that think like engineers : they run every critical user journey, catch failures before users do, and self-heal as the codebase evolves. Real AI teammates, not test scripts that break on impact.

We’re venture-backed and led by operators who’ve scaled Meta’s testing infrastructure, launched Uber’s global playbooks, and grew Deliveroo from zero to hypergrowth. We know what elite execution looks like and we’re hunting for one more builder to help us rewrite the rules of software quality.

What You’ll Do

• Build and own growth channels from zero across outbound, content, partnerships, communities, and experiments
• Work directly with founders to design and run founder‑led GTM loops
• Turn customer and market signals into repeatable growth systems
• Rapidly test hypotheses across ICP, messaging, channels, and conversion paths
• Identify and double down on what compounds, kill what doesn’t
• Operate inside the product engine to align growth with real user value

What We’re Looking For

• Relentless executor: you move fast, learn faster, and don’t wait for permission
• Builder mindset: you create systems, not one‑off campaigns
• High ownership: growth lives and dies with you
• Strong first‑principles thinking and commercial intuition
• Comfortable operating without a playbook, PMF, or safety net
• Clear communicator who can work at founder altitude

Ideal Background

We hire for mindset, not pedigree. You might have:

• Built growth at an early‑stage startup or developer tool
• Run scrappy outbound or demand loops that actually converted
• Experience in growth, GTM, product, ops, or founder‑adjacent roles
• Exposure to technical products or engineering audiences
• Shipped experiments in ambiguous environments

Why This Role Matters

Autonomous testing is inevitable. AI agents will replace brittle scripts and manual QA. Duku AI is building that future now.

This is an early, defining hire. You’ll shape how growth works at Duku before the rules are written. Real ownership. Real impact. Direct line to the founders.
