About the role

The Senior Product Designer is responsible for shaping complex product experiences that require a strong understanding of user needs, business objectives, and system dependencies. The role focuses on structuring end-to-end user journeys, translating research insights into practical design solutions, and supporting teams in navigating ambiguous problem spaces.

The initial primary focus of this role is bp’s enterprise design system — designing and maintaining the tokens, components, and patterns that keep bp’s digital products consistent, accessible, and easy to build. Over time, the role will transition to contribute across the broader Developer Experience (Dev Ex) portfolio, including the internal developer platform and its tooling, and AI-enabled developer tooling.

Work at this level requires strong foundations in interaction design, service thinking, and visual design. The role contributes to the development of scalable product patterns and ensures design outcomes remain consistent with established systems and accessibility standards. Ensuring EAA / WCAG AA compliance across all design-system tokens and components is a core driver of this role, not an afterthought.

Awareness of emerging technologies, including AI-enabled tools and product capabilities, supports informed design decisions and efficient design workflows.

This role operates across the design-system federation model, collaborating closely with product managers, engineers, researchers, and other designers — both within the Design Engineering team and across the product teams adopting the design system. Partnership with frontend engineers is central, ensuring strong consistency between Figma designs and delivered code.

Engagement may also extend to federation delegates, content, operations, and support teams when product experiences intersect with broader operational processes. The team values thoughtful discussion, constructive feedback, and knowledge sharing. Designers contribute to maintaining strong design practices while driving adoption of the design system across disciplines.

What you will deliver

Design-system ownership:
Own and evolve the design system — define and maintain tokens, components, and patterns in Figma; produce usage guidance, specifications, and documentation; and enable teams to adopt the system correctly and consistently.

Figma-to-product consistency:
Act as the design guardian for the design system, ensuring components are used correctly across products and partnering with engineers to close design-to-build gaps between Figma and delivered code.

Accessibility ownership:
Ensure design-system components meet EAA / WCAG AA requirements by design — embedding accessibility into specifications, states, and usage guidance, and considering all component states and edge cases.

Research and insight synthesis:
Plan or support interviews, usability testing, and behavioural observation, synthesising findings into journey maps, experience principles, and structured design recommendations.

Experience design:
Define user journeys, task flows, and interaction patterns for complex product workflows. Service blueprints may be created to illustrate user interactions and supporting system processes.

Design execution and prototyping:
Develop wireframes, prototypes, and high-fidelity interfaces using established design systems and accessibility standards.

Design facilitation and collaboration:
Facilitate workshops, feedback sessions, and collaborative discussions to improve design outcomes and support shared understanding across product…
