Ihre Aufgaben
We're looking for a Senior Product Designer to join our team and take full ownership of design at OPTIMUSE. In this role, you'll work across the entire product — from shaping individual features to defining our design system and product vision. You'll actively shape how we learn from users, partnering closely with product to turn insights into well-crafted interfaces. As the sole designer on a scaling team, you'll be at the center of fast decision and iteration cycles.
Job description
Own end-to-end product design across features — flows, interactions, UI, and prototypes.
Maintain and evolve the OPTIMUSE design system, ensuring visual and experiential consistency across the product.
Contribute to product vision at the macro level, shaping the design language of OPTIMUSE as we scale.
Actively shape user research — collaborating on study design, feeding into validation loops, and translating findings into design decisions.
Collaborate closely with product, engineering, and customer success to bridge user needs and product execution.
Use AI tools actively as a productivity multiplier — for research synthesis, rapid ideation, prototyping, and iteration.
Ihr Profil
3+ years of professional experience in digital product design, specifically in software or SaaS products.
You've worked across more than one digital product and bring cross-context perspective to design decisions — you know what good looks like because you've seen it in different shapes.
Hands-on experience owning a design system or contributing significantly to one.
Confident shaping research direction — you don't just consume findings, you help design the questions.
AI-native workflow: you actively use AI tools as part of your day-to-day design process and can speak to how they've changed the way you work.
Comfortable with ambiguity and shifting priorities — you've worked in a startup or scale-up and know what that means in practice.
Proficiency in our core toolset: Figma, Storybook, and AI-assisted workflows (Claude, Cowork/Code or equivalent).
Experience with unmoderated usability testing tools (e.g. Maze, Lyssna) — we're building this practice and looking for someone who can help establish it.
Working proficiency in English required. German is nice to have.
Warum wir?
Be the design owner at a company that has found its market and is now scaling — your work shapes a product that real asset managers and building professionals rely on.
Work with a talented, international team (~25 people, 10 nationalities) that values craft, collaboration, and moving fast.
Modern office in Vienna's 2nd district. We work on site, with home office days possible upon request.
Flexible working hours outside of core times — and plenty of ways to recharge, from table tennis to team events and company celebrations.
