Job description

Most software assumes the user will learn its interface. We're building an interface that learns the person.

What should an AI companion become when its users did not grow up with software? A human face, an abstract presence, or voice alone? When should it speak first? How does it show it is listening, remembering, acting? These are not polish questions.

You'll answer them through rapid experiments with real seniors in real homes. This interaction model barely exists as a discipline. You'll help invent it.

Have the best time of your career working on an awesome, meaningful product with super talented people.

• A voice-first interaction model: turn-taking, interruptions, silence, proactive moments, recovery when Olympia gets it wrong. Less like operating software, more like being understood.
• A generative interface system: the screen assembles the right thing around the conversation (a memory, crossword, reminder, photo) and stays coherent, accessible, trustworthy.
• Embodiment grounded in evidence. Avatar, abstract presence, or voice alone? Prototype, test during onboarding, learn what works.
• A calm, accessible home experience. Legible with low vision, forgiving of shaky hands, warm without being childish or clinical.
• The family connection loop. Messaging that turns everyday moments into reassurance and prompts like "call your mum", while protecting the older adult's agency and privacy.
• An agent that can act: medication, appointments, transport, everyday tasks through conversation.
• A research and experimentation engine. Fast prototypes, field tests, clear measures of trust. We have hypotheses; you replace them with evidence.

A specialist studio handles marketing and visual identity. This role owns the product experience: interaction system, generative UI, embodiment, accessibility.

WHO WE'RE LOOKING FOR

• Obsessed with human-computer interaction and the future of AI interfaces. You have opinions on why today's voice assistants feel awkward, and the curiosity to test them.
• You think in systems, behaviours, and moments, not screens.
• You prototype to learn: Figma, code, motion, AI tools, whatever gets an idea in front of a user fastest.
• You do your own research. Sit with an older adult, notice what they do rather than what they say.
• You know how hard simple is. Accessibility is part of the architecture, not a checklist.
• Shipped consumer products. Your portfolio shows craft and what changed after real people used it.
• High agency. You'd rather test a rough version in a home this week than wait for a perfect brief.
• You care about the mission. Low ego, kind, hard-working. No politics.

BONUS

• Voice UI, conversational design, generative interfaces, motion, front-end prototyping, health or care products, designing for older adults.
