Change Software Forever
Most engineering roles build software nobody fully trusts. This one builds the trust layer itself. AI is making engineers dramatically more productive. The problem is nobody fully trusts what AI ships.
Why this matters now
AI is rewriting how software gets built. But shipping still breaks on testing. Engineering leaders are desperate to release faster without dropping quality, and they can't get there with manual QA or brittle test automation.
Here's the bigger shift: as AI writes more of the code, the bottleneck moves from generating software to trusting it. Nobody owns that trust layer yet. Duku is building it, autonomous agents that simulate real users, catch critical failures before production, and self-heal as the product evolves.
Backed by experienced operators and investors, we're building what we believe will become a core layer of the modern software stack. We're looking for an exceptional Full Stack Software Engineer to help build it. Not someone to maintain a codebase. Someone to define one.
What You’ll Do
- Ship fast, learn faster : We deploy daily, not monthly
- Talk to users, shape the roadmap : Sit in the trenches with founders on calls that define what we build
- Train AI agents: Design LLM-powered testers that explore, learn, and adapt in real time
- Own the stack :Python, TypeScript, cloud infra, from commit to production
- Turn prototypes into production : Run real experiments on models, embeddings, and retrieval pipelines
What We’re Looking For
- Relentless drive: You execute fast, adapt faster
- Startup scar tissue : You’ve shipped product with no safety net
- Fluency with AI/LLMs : LangChain, vector stores, prompt engineering
- Full-stack firepower : Frontend, backend, infra, no silos
- Product obsession : You care more about outcomes than outputs
- Experimental instinct: You build → test → learn → repeat
Ideal Background
There’s no perfect pedigree. We hire for mindset, not credentials. That said, you might have:
- Shipped AI features in prod
- Built something from 0 to 1
- Thrived in chaos with high ownership
Why This Matters
Software is accelerating. QA hasn’t kept up. Autonomous testing is inevitable, and we’re building it.
Five years from now, every high-velocity team will rely on AI agents like ours to ship faster, safer, and smarter.
Join now, and help make that future real, before someone else does.
Skills Required
- Experience shipping AI features in production
- Experience building products from 0 to 1
- Experience working in high-ownership startup environments
- Fluency with AI and LLM technologies, including LangChain, vector stores, and prompt engineering
- Full-stack experience across frontend, backend, and infrastructure
- Ability to work with Python and TypeScript
What We Do
Duku AI is building autonomous testing infrastructure for the AI era. Its platform uses intelligent agents to simulate real users navigating software, identify critical failures that conventional tests miss, and help teams verify that products work before release. By automating quality assurance and adapting as products evolve, Duku aims to provide a trust layer for AI-written software and modern engineering teams.
