Conceive Tuttim's future experiences, from discovery to delivery
Clarify the scope and user needs by gathering on-the-ground facts (user feedback, interviews, stakeholders)
Lead exploration and solution generation, from lo-fi (journey maps, sketches) to hi-fi (functional logic, prototypes) to align the team
Evaluate solutions in terms of user desirability, business impact and implementation cost, relying on field evidence (user tests, design critiques, data) to defend your choices with proof, and in collaboration with product managers
Contribute to the improvement and enrichment of our Design System, and ensure a coherent experience between Tuttim and Epsor — from identifying needs to specs and acceptance testing
Propose use cases where AI can advance our design organization and then lead experiments. In particular to accelerate user research, prototyping, and developer handoff.
Challenge our organization and be an actor in experiments related to our processes

5 to 8 years of experience in Product Design, including at least 3 years on native mobile (iOS and/or Android) in production, ideally in fintech, B2C or scale-up.
Designer on web and mobile taking into account the specificities and constraints of each platform
Challenge a need to ensure that a solution addresses a real problem, speak to users to capture their expectations, and defend your choices with evidence (user tests, data, design critiques)
Propose, rationalize and arbitrate between several approaches with regard to user needs and project/product/tech constraints
Take into account a large number of inputs to obtain the most optimized trade-off: user edge cases, business edge cases, security, technical infra, device
Design a complete system (UX, UI, functional logic) ready for delivery from the first iteration
Use standard design and design system management tools (Sketch, Figma, FigJam) and quickly upskill on new ones (AI-driven design)
Use AI as a real productivity lever in daily work — in both user research and prototyping.
Proactively coordinate with Product Managers, engineers and stakeholders, and you know how to bring methods to improve collective efficiency (rituals, design reviews, handoff, impact measurement)
Be comfortable in a fintech environment where clarity, trust, security and accessibility are non-negotiable
Embody the values of teamwork and trust 💚
