Job Description

We’re an early-stage, venture-backed startup building a product experimentation platform for engineers and data scientists. We’re looking for a Senior Product Designer who combines strong product thinking, elegant visual design, and a deep understanding of complex UX patterns for a technical audience.

You’ll report to our Head of Design and work closely with engineers to define problems, shape solutions, and ship high-quality experiences. There’s no PM layer—you’ll help define product direction, map user flows, and bring clarity to ambiguity. We have a basic design system in place. Your focus will be applying it rigorously while continuing to shape the patterns that bring consistency and clarity to every corner of the product.

What You’ll Do

Own design for core product areas—from early exploration to final execution
Turn complex logic and data into clear, intuitive workflows and interfaces
Apply and evolve our design system to ensure consistency and usability
Collaborate directly with engineers to scope, iterate, and ship quickly
Prioritize work for impact—balancing ideal UX with release constraints
Design without detailed specs and advocate for solutions that serve user needs
Influence product direction by surfacing insights and proposing improvements

You Might Be a Fit If You

Have 5+ years of experience designing B2B SaaS products, especially in early-stage or complex tool environments
Are strong in both visual UI and complex UX design—able to craft elegant screens and untangle dense workflows
Have designed dashboards, data visualizations, or multi-step workflows with clarity and precision
Thrive without a PM—comfortable identifying problems, scoping solutions, and collaborating directly with engineers
Think in systems and design for scalability, clarity, and long-term usability
Work iteratively—comfortable proposing early solutions, gathering feedback, and refining quickly
Are highly organized and communicative—keeping your own priorities clear and collaborating well in Figma, writing, and live sessions

Bonus Points

Experience designing for technical or operational users (e.g., devtools, analytics, internal tooling)
Familiarity with charting libraries, state logic, or permission models
Experience working on products or teams that experiment frequently—you understand iteration, A/B testing, and designing for learning
