Senior Product Designer (Part-time 80% / 32 hrs) at Forteil GmbH - bonify

About us

Join bonify, Germany’s leading platform for credit scoring and financial management. We are on the mission to revolutionize the FinTech industry and make the credit score and financial data available and transparent for our users.

We are hiring a Senior Product Designer (part-time, 32hrs/week) to shape how millions of users understand and improve their financial health across mobile and web.

You'll own design end-to-end for a defined product area, from framing the right problems through research, prototyping, validation, and delivery. Our focus is on creating more value beyond the credit score, making complex financial information feel simple, useful, and trustworthy, and embedding AI into both our products and our daily work.

This is a hands-on, high-autonomy role with a strong research mindset. You'll speak directly with German-speaking users, work closely with Product, Engineering, and Data, contribute to our design system, and support less experienced designers through collaboration and feedback.

Your tasks

• Lead product design for a defined area across mobile and web.
• Turn complex financial and credit-related information into experiences that feel simple, useful and trustworthy.
• Plan and conduct customer research, interviews and usability testing, particularly with German-speaking users.
• Translate qualitative research and behavioural data into clear product decisions.
• Create user flows, interaction models, prototypes and polished product experiences in Figma.
• Work closely with Engineering to ensure solutions are feasible, scalable and implemented with high quality.
• Partner with Product and Data to define what success looks like and evaluate the impact of shipped work.
• Contribute to and improve reusable patterns and our design system.
• Use AI practically in your day-to-day work to accelerate research, exploration, prototyping and documentation.
• Help shape AI-powered customer experiences where relevant — while applying strong judgement around trust, clarity and user control.
• Share your expertise, give thoughtful feedback and help raise the quality of design across the team.

Requirements

• You have around 6–8 years of experience in product design, ideally working on digital consumer products.
• Availability for a fixed 32 hours per week (80%)
• Strong experience designing end-to-end product experiences across mobile and web.
• Advanced skills in Figma, interaction design and prototyping.
• Strong hands-on user research experience — not only consuming research, but planning and conducting it yourself.
• The ability to simplify complex, data-heavy or sensitive topics into clear customer experiences.
• Strong product thinking and the ability to connect design decisions to customer and business outcomes.
• Experience working closely with Product, Engineering and Data in cross-functional teams.
• Confidence working independently and taking ownership from ambiguity through delivery.
• German at C1 level or above, including the ability to conduct customer interviews and usability studies.
• Berlin-based (Hybrid Working Model)
• Strong practical experience using AI tools in your design workflow — for example in exploration, synthesis, prototyping or documentation.
• A collaborative, kind and constructive working style.
• Experience in fintech, banking, financial services or another regulated/data-intensive environment is a strong plus.
