About the Role

We are seeking a Senior Product Designer to lead core user experiences for Sift's platform. You will design intricate, data-rich interfaces that empower engineers to monitor, analyze, and make critical decisions about mission-critical hardware systems. This role involves user research, interaction design, prototyping, and UI execution, collaborating closely with Product Management and Engineering. You will utilize and help evolve our design system, leveraging AI-assisted tools for faster iteration.

Responsibilities

  • Own the end-to-end design process for core product experiences, from problem discovery and user research through prototyping, validation, and launch.
  • Conduct user research, including on-site customer visits, to understand how engineers work with complex telemetry data and translate their needs into intuitive workflows.
  • Design sophisticated, data-dense interfaces with a high bar for usability, interaction quality, and visual craft.
  • Partner closely with Product Management and Engineering to define problems, evaluate tradeoffs, and ship improvements based on user feedback and product outcomes.
  • Use AI-assisted design and development tools, such as Claude Code and Figma MCP, to build interactive prototypes, explore solutions, and accelerate iteration.
  • Contribute reusable components, interaction patterns, and improvements to Sift's design system.
  • Participate in design critiques, share new tools and workflows, and help raise the quality of design across the team.

Requirements

  • 6+ years of experience in product design (UI/UX), with a strong portfolio demonstrating ownership of complex software experiences.
  • Strong interaction design skills, particularly for technical, data-rich, or workflow-heavy applications.
  • Ability to work across the full design process, from user research and information architecture to detailed interaction design and polished visual interfaces.
  • Experience building interactive prototypes to communicate, test, and refine design solutions.
  • Strong systems thinking, with the ability to simplify complex workflows while maintaining consistency across a product.
  • Excellent communication and storytelling skills, with the ability to explain design decisions, incorporate feedback, and build alignment across teams.
  • Interest in using AI-assisted tools to improve design workflows, with a willingness to experiment and adopt new approaches.
  • Ability to work independently, navigate ambiguity, and move quickly without sacrificing design quality.
  • Portfolio Required: Applications without visual work samples will not be considered.
