Senior Product Designer

About the Role

We are looking for a Senior Product Designer to join our growing design team. This is a hands-on role where you’ll work across discovery, user flows, wireframing, prototyping, and delivery to improve the Once For All ecosystem. You’ll collaborate closely with researchers, product managers, and engineers to design intuitive, scalable solutions for complex workflows across all Once For All products. This role is ideal for someone who thrives in complex SaaS environments, enjoys turning research insights into clear design solutions, and is eager to leverage AI tools to make design more efficient and consistent.

Responsibilities

• Take ownership of end-to-end product design for core areas of our SaaS ecosystem, from discovery and user flows through to high-fidelity delivery.
• Partner with UX researchers, product managers, and engineers to translate insights into impactful design solutions.
• Apply systems-thinking to design scalable workflows, dashboards, and multi-role user journeys across compliance, ESG, procurement, and marketplace features.
• Create wireframes, clickable prototypes, user flows, and high-fidelity designs that bring clarity to complex problems.
• Contribute to and evolve our design system, ensuring consistency and scalability across products.
• Enhance user engagement with micro-interactions and animation where appropriate.
• Use AI-powered tools to aid speed, efficiency, and consistency.
• Share knowledge and support the wider design team through collaboration and constructive feedback.
• Champion collaboration over handoff, ensuring design and research inform each other throughout the process.

Qualifications

• 7+ years of product design experience, with a strong focus on B2B SaaS platforms.
• Portfolio that demonstrates complex workflows, dashboards, data-heavy systems, or multi-role experiences (not only visual/UI).
• Proven ability to design and iterate wireframes, user flows, prototypes, and interaction patterns.
• Strong proficiency in Figma (including variables, tokens, prototyping, and animation).
• Experience working with design systems, accessibility standards, and responsive design.
• Collaboration experience with UX research, including usability testing and data-informed design.
• Comfortable working in an agile, cross-functional, regional environment.
• Curiosity and openness to AI tools as part of your workflow.
• Excellent communication skills in English (French or Spanish a bonus).

Preferred Skills

• Experience designing for compliance, procurement, ESG, or marketplace systems.
• Familiarity with motion design and micro-interactions to improve usability.
• Understanding of front-end development concepts (HTML, CSS, React) to collaborate effectively with engineers.
• Experience mentoring or coaching junior designers.
