Design Engineer

About Chai Discovery Chai Discovery is re-architecting drug discovery by building frontier AI foundation models to design molecules. The founding Chai team has brought together the leading researchers in this space, with seminal research accomplishments at top AI labs. The team has led AI-for-biology programs at premier labs, co-invented protein language modelling, built state-of-the-art folding algorithms, and sold AI adopted by top-10 pharma companies. The company is backed by top-tier investors, including OpenAI, Thrive Capital, Dimension, Conviction, Lachy Groom, Amplify, and many more. We’re looking to add a few members to our team of scientists and engineers, who obsess over creating the most powerful AI models for antibody discovery, and turning them into products that can transform how medicines are made. About the role As Chai’s first Product Designer, you will turn cutting-edge AI science into intuitive tools that scientists love. You’ll own the end-to-end design process, user research, wire-frames, high-fidelity mock-ups, and design-system stewardship, for our web apps and dashboards that let biologists explore model results, run jobs, and manage data. You’ll guide the product to optimize clarity of workflows, consistency of visual language, and user delight in a domain that is often cluttered and technical. At Chai, we’re entering a pivotal stage. After years of foundational R&D, our models are moving beyond protein structure prediction and into real-world therapeutic engineering. We're now tasking our AI models on a broad spectrum of drug development challenges, at an exciting scale of wet-lab validation. This is not a typical role — it’s a chance to push the boundaries of drug discovery by building some of the most advanced AI drug design models ever built. About you We’re looking for a mission-driven product designer who wants to define the gold standard for AI-powered drug-discovery products. You should have: Design depth: 4+ years designing web or data-heavy SaaS products; a portfolio that shows end-to-end ownership of complex workflows Comfortable moving from low-fi sketches to polished Figma files and interactive prototypes Able to learn enough about molecular biology and AI/ML concepts to model user mental maps accurately Skilled at planning and running user-research sessions, interviews, usability tests, and rapid feedback loops with scientists or enterprise users Translate insights into clear information architecture, task flows, and interaction patterns Communication & collaboration Can articulate design decisions to cross-functional audiences (engineers, product managers, ML researchers, wet-lab scientists) Fosters a culture of design thinking, documenting guidelines and evangelizing best practices Mindset: Bias for simplicity and minimalism in highly technical domains; you enjoy turning complex topics into elegant UIs Comfortable iterating quickly in a startup where requirements, and underlying science, evolve fast Clear communicator who can simplify complex science for external partners and internal stakeholders Nice-to-have experience: Designing for scientific or data-visualization products (bioinformatics tools, lab automation, analytics dashboards) Basic front-end skills (HTML/CSS/React) that help you communicate with engineers and prototype interactions What we offer Frontier technology: we’re developing the next frontier of AI-driven drug discovery that will fundamentally change how new therapeutics are created. World-class team: opportunity to work with world-renowned leaders in the AI x biology and technology ecosystem who have created some of the most impactful advancements. Highly competitive compensation: we offer highly competitive salary, equity package, and healthcare and wellness benefits. Velocity and ownership: we move incredibly fast, which means continuous learning and career growth opportunities are a guarantee. Every team member owns a significant slice of the roadmap. Strong team culture: Collaborative and supportive startup culture in a small and high-energy team who are guided by our mission to increase the efficiency of creating new medicines and positively impact millions of lives. #J-18808-Ljbffr
