About the role

Senior Product Designer owning the design function at Smartnumbers, collaborating with Product Managers and engineers to enhance fraud prevention and customer experience.

Responsibilities

You will own the entire design function at Smartnumbers: user research, interaction design, prototyping, design system, and facilitation.
You will work as a close partner to two Product Managers and their engineering teams across our fraud prevention and upcoming new products.
This is an opportunity for a designer who wants real ownership and influence.
You will have direct customer access, a tight Design, Product, and Success team feedback loop, and no layers of approval.
You are the design authority.
You decide which customers to speak to, which problems to investigate, and how the product should feel.
You work directly with Product Managers and engineers to ship work grounded in user evidence.
Success in this role means features ship with user validation, design quality remains high across the portfolio, and the team consistently makes better product decisions because of the research, facilitation, and design thinking you bring.

Circa 5 to 8 years of product design experience in B2B SaaS or enterprise software environments
Strong user research skills: interview design, usability testing, synthesis, and problem framing
Confident and proactive communicating directly with enterprise customers without needing support
Expert in interaction and visual design: clarifying data, indicating relationships, and hinting at behaviour using colour, style, iconography, typography, and visual hierarchy
Proficient in Figma (or equivalent) for wireframing, prototyping, high-fidelity mockups, and engineering handoff
Ability to create and facilitate workshops with cross-functional stakeholders to drive outcomes
Demonstrable use of AI design tools to accelerate design output and increase personal throughput
Proven experience as the sole or primary designer on a product team, comfortable owning the full design function without peer support or a design manager
Understanding of design systems and component-based UI architecture
Good understanding of the agile product development process, with the ability to enhance user experience in small iterative deliveries
Organised documentation practices so research and design decisions are accessible to the wider team on demand.
