Product Designer/Sr. Product Designer

About The Position

As a Product Designer/Sr. Product Designer at Matterworks, you will shape how scientists interact with Pyxis, our application layer for foundation models of biochemical data. The role spans two design challenges: shipping end-to-end product work in our core web application, and helping us invent the patterns that make our models accessible across emerging surfaces, including our MCP connector and other agentic interfaces. The conventions for how scientists work with AI-native tools in biology don't fully exist yet. You'll help us define them.

Requirements

A portfolio that demonstrates end-to-end ownership of complex product surfaces alongside systems thinking (reusable patterns, components, or design primitives). Please include a portfolio link with your application.
Genuine love for the craft of design. You sweat the details because you can't help yourself, study products you admire, and find joy in the work itself.
Strong self-direction. You can take a brief, run with it independently, and come back with credible progress without close supervision.
Experience designing data-dense interfaces (tables, plots, dashboards).
Curiosity about scientific domains. You don't need a biology background, but you should be excited to learn about mass spectrometry, omics, and the workflows of lab scientists.
Comfort pairing with engineers through implementation, not just at handoff.
Comfort with ambiguity and a bias for shipping. You'd rather get something in front of users in a day and iterate than design in isolation for a week.
Fluency in Figma, rapid-prototyping tools (Claude, v0, Cursor, or similar), and clear written communication.

Nice To Haves

Experience designing AI-powered, agentic, or model-driven products is a plus, especially work that spans multiple surfaces or modalities.

Responsibilities

Iterate at high velocity: Produce dozens of design explorations through sketching, Figma, and coded prototypes in tools like Claude and v0.
Craft beautiful final designs: Bring final work to a high bar of polish in typography, hierarchy, and interaction.
Build reusable components: Turn recurring patterns into components that compose across the web app, MCP, and agentic surfaces.
Understand users deeply: Stay close to scientists through user interviews, customer calls, and session replay reviews.
Collaborate across the team: Work with PM, engineers, and scientists to align on user needs and tradeoffs.
