Define and drive the design direction for our internal and B2B backend tools, from information architecture and system design through to polished, production-ready interfaces.Audit and organize our existing backend toolset - mapping how features, workflows, and systems relate to one another and identifying where consolidation, clarity, or restructuring will have the most impact.Leverage AI tools and prototyping to build and validate ideas directly - you're comfortable getting your hands into production, not just handing off specs.Lead features end-to-end: partnering with product managers and engineers to gather requirements, frame problems, iterate on solutions, and deliver organized, well-documented work.Hold a high bar for the UX of every tool you touch, with each one feeling considered and purposeful, not just functional.Own the full arc from strategy to pixels, exercising your own judgment to move work from concept to implementation.Present and defend design decisions clearly to stakeholders, grounding your rationale in user needs and business impact.Collaborate closely with engineering and data teams to design interfaces that make complex, high-density information legible and actionableMentor other designers on the team, offering direct and constructive feedback that raises the quality of the work.Foster a culture of honest, empathetic communication and high craft.
