About us:
Causaly is redefining how humans acquire knowledge and develop insights in biomedicine. Our AI-powered platform enables researchers and decision-makers to discover and interpret evidence from millions of scientific publications, clinical trials, regulatory documents, and other complex data sources in minutes.
We are building the world’s most advanced biomedical knowledge platform, powered by a high-precision Knowledge Graph and GenAI capabilities. Our technology is already used by leading biopharmaceutical organizations to accelerate drug discovery, improve safety, and drive better decision-making.
Backed by top-tier investors including ICONIQ, Index Ventures, Pentech, and Marathon, we are scaling rapidly and expanding our product suite and market presence.
The role
We’re looking for a Senior Product Designer to join our small but impactful Product Design team to own and shape the experience of our AI platform for life sciences.
This is a senior IC role embedded within a cross-functional team, focused on agentic research workflows and AI-driven user experiences for our customers.
You’ll lead end-to-end design from discovery through to delivery, defining how users interact with complex, intelligent, evidence-backed systems in intuitive, trustworthy and high-impact ways.
This is not a traditional product design role. You will be designing systems, workflows, and behaviours — shaping how humans collaborate with AI in scientific and expert domains.
What you’ll be doing
Product and experience design
Own the end-to-end design of product experiences from discovery to delivery
Design AI-native workflows and agent-driven experiences, translating complex capabilities into intuitive interactions
Define system behaviours, states and flows — not just screens
Prototype rapidly across different fidelity levels using AI and coding agents to explore and validate ideas
Discovery and problem definition
Lead product discovery, framing problems and identifying high-impact opportunities
Conduct user research and usability testing to inform decisions
Synthesise insights into clear product and design direction
AI interaction and systems design
Design interaction models for human–AI collaboration, ensuring clarity, control and trust
Work with non-deterministic systems, shaping experiences that account for uncertainty and variability in AI outputs
Contribute to defining new patterns for agentic and generative interfaces
Prototyping and implementation
Prototype ideas using modern AI tools and code (e.g. Cursor, Claude Code) to explore and validate concepts quickly
Create interactive, production-adjacent prototypes beyond static design tools
Contribute lightweight code changes and PRs where it accelerates learning and delivery
Partner closely with engineers to ensure high-quality implementation
Cross-functional collaboration and ownership
Partner closely in a trio model with Product Managers and Engineers to shape product strategy and roadmap
Translate business goals into product direction, user experience, and execution
Drive projects forward in ambiguous environments with a high degree of ownership
Systems and craft
Design scalable systems, patterns and components
Contribute to and evolve our Causaly design system
Maintain a high bar for interaction, visual design and overall product quality
Leadership and influence
Act as a design leader within your team, raising the bar for quality and clarity
Communicate ideas effectively to stakeholders across product, engineering and leadership
Contribute to design culture, critique and continuous improvement
Take ownership of your domain and decisions backed by user feedback, analytics and business rationale
What we’re looking for
Core experience
5 – 8 years experience in product design (UX/UI), ideally in SaaS, AI or technical products
Proven track record of designing and shipping complex products or workflows end-to-end
Strong portfolio demonstrating product thinking, craft and impact
AI and systems thinking
Experience or strong interest in designing AI-powered or data-rich products
Ability to think in systems — designing flows, behaviours, patterns and interactions
Comfortable working with ambiguity and shaping new UX paradigms
Prototyping and builder mindset
Comfortable prototyping with code or AI-assisted tools (e.g. Cursor, Claude Code, or similar)
Ability to move fluidly between design and implementation
Experience contributing to production codebases (e.g. small PRs, functional prototypes) is a plus
You’re comfortable building product yourself – taking ownership and doing what it takes to bring ideas to life
Strong design craft
Strong interaction and visual design skills
High proficiency with modern design tools (our key tool stack includes figma, Claude Code, Cursor, Miro and prototyping tools, etc.)
Experience building and maintaining design systems
Experience working in cross-functional product teams
Strong communication and storytelling skills
What we’d like to see
Experience with generative AI, agent-based systems or conversational interfaces
Background in healthcare, life sciences or other complex domains
Experience in fast-paced start-up environments
Experience designing for trust, transparency and judgement in AI systems
