Machine Learning Engineer
About this role
You're not joining a QA team. You're joining a mission to make broken software a thing of the past.
At Duku AI, we're building the next generation of autonomous testing agents — systems smart enough to understand what your product is supposed to do, find where it fails, and fix themselves when the codebase changes. No flaky test scripts. No brittle selectors. No 3am pages because a deployment broke something no human thought to check.
As a core member of our team, you'll work at the intersection of AI systems, developer tooling, and product engineering. You'll own meaningful problems end-to-end — from shaping how our agents reason about software behaviour, to ensuring our platform scales across the world's most demanding engineering teams.
This is a high-autonomy role. You'll collaborate directly with founders who have built and scaled infrastructure at Meta, Uber, and Deliveroo. You'll move fast, think deeply, and ship things that matter.
What you'll do:
• Design and build systems that make autonomous software testing a reality at scale
• Work closely with engineering and product to define how AI agents interact with real-world codebases
• Own your work from first principles through to production — with full context and full accountability
• Shape the culture, processes, and technical standards of a team that's serious about craft
What we're looking for:
• Deep technical ability and an instinct for elegant solutions to hard problems
• Someone who raises the bar around them — for quality, for thinking, for execution
• A builder who thrives with ambiguity and ships with conviction
• Curiosity about AI, autonomous systems, and the future of developer tooling
If you've ever been frustrated watching slow, manual QA block great engineering — this is your chance to fix it.
Company at a glance
As AI commoditises code generation, the bottleneck moves from writing software to trusting it. Verification is the layer that determines whether AI-generated code ships to production or stalls in review.
Code-level tests rot every time the implementation changes.
Product-level verification does not care how the code was written, only whether the product still does what users came to do.
Duku continuously simulates your users so you can trust every release, before it ships.
