Duku AI

Duku AI in Greater London is seeking a Full Stack Software Engineer to play a key role in building trust in AI-driven software solutions. This position offers the opportunity to ship products at a rapid pace and define new features that leverage AI for testing and quality assurance. The ideal candidate will thrive in a fast-paced environment, be experienced in AI/LLMs, and be driven by product outcomes rather than outputs. Join Duku AI to help shape the future of software development.

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 Product obsession : You care more about outcomes than outputs 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.

Duku AI in London is seeking a Machine Learning Engineer to innovate in autonomous software testing. You'll design systems to ensure AI software reliability, collaborating with talented founders from giants like Meta and Uber. This role focuses on creating new models, shaping team culture, and leading meaningful projects. Ideal candidates will possess deep technical expertise, a passion for AI, and an instinct for elegant solutions. Join us to redefine software quality and trust.

Most ML roles optimise models in isolation. This one builds the intelligence layer that determines whether AI-generated software can actually be trusted in production. 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 Machine Learning Engineer to help build it. Not someone to tune existing models. Someone to design new ones. 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.

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 You will own engineering execution end-to-end. You will take ideas from zero to production. You will help define the technical DNA of the company.
