Senior Product Designer

Sift Stack, Inc.•Marina del Rey, CA

15d•$160,000 - $230,000•Hybrid

About The Position

Sift is seeking a Senior Product Designer to own core user experiences across its data infrastructure platform for hardware engineering teams. The role involves designing complex, data-rich interfaces that help engineers monitor, analyze, and make decisions about mission-critical hardware systems. This is a hands-on position spanning user research, interaction design, prototyping, and polished UI execution. The designer will work closely with Product Management and Engineering from problem definition through launch, use Sift's design system, and help evolve it. The role calls for strong design craft and systems thinking, direct engagement with technical users, and interest in using AI-assisted tools to explore, build, and iterate faster. Sift collaborates in person twice a week in its Los Angeles or San Francisco office, on Mondays and Thursdays, and teams meet in Los Angeles for a full week each quarter. Relocation to either office may be offered to the right candidate. Applicants must be U.S. citizens, lawful permanent residents, or other protected individuals in compliance with ITAR/EAR regulations. A portfolio or relevant design work link is required; applications without visual work samples will not be considered.

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.
Must be a U.S. citizen, lawful permanent resident, or protected individual such as an asylee or refugee in compliance with ITAR/EAR regulations.
Must include a portfolio link or relevant design work; applications without visual work samples will not be considered.

Nice To Haves

Experience designing data visualization, observability, monitoring, analytics, or other data-intensive products.
Familiarity with charts, dashboards, real-time data displays, or complex technical workflows.
Experience designing tools for engineers, developers, scientists, or other highly technical users.
Background in aerospace, defense, robotics, industrial systems, or advanced hardware.
Hands-on experience with Claude Code, Figma MCP, or other AI-assisted prototyping and development tools.
Experience working at an early-stage startup and contributing to a growing design system.

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 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.
