About Us Most of the molecules driving human biology are invisible to us. Mass spectrometers already detect metabolites, lipids, and peptides, but the vast majority of those signals never get identified. A typical experiment names a small fraction of its features and discards the rest. We call this biology's dark matter. It’s signal-rich and mechanism-defining, yet almost entirely opaque.

Matterworks is building the foundation models that make that dark matter legible. Our Large Spectral Models do for biochemical biology what AlphaFold and ESM did for proteins: turning a library-bound discipline into something predictable and generative, and embedding it at every stage of R&D.

Come build the future of biological discovery with us.

Position Overview

We're hiring a Product Management Intern for summer 2026. You'll work directly with our Product leader across the full surface area of building an AI-native product: roadmap, user research, launches, marketing, and the dozens of small things that keep a fast-moving product team running.

This is a generalist role for someone who wants to learn how a modern AI product gets built from the inside. You'll see firsthand how decisions get made about product, design, and go-to-market for foundation models in biology.

The internship runs full-time over summer 2026, with the possibility to extend 3 months (6 months total).

Key Responsibilities

• User research support: Recruit interviewees, run conversations alongside the PM, and translate observations across users into patterns the team can act on.
• Market analysis: Track the broader space we operate in and surface what matters back to the team.
• Product analytics: Pull and read usage data, dashboards, and session replays to surface patterns about what's working and what isn't.
• Translating ideas to specs: Turn ideas, observations, and customer signal into clear specs that engineers can build from.
• Launch coordination: Help ship product launches by coordinating across engineering, design, science, and marketing.
• Content and marketing: Support blog posts, one-pagers, conference materials, and social content tied to product launches.

Qualifications

• Exceptional organization and adaptability. You can juggle many threads at once, keep track of details, and switch contexts without dropping things.
• Strong written and verbal communication. You can write clearly, summarize a meeting, and translate fuzzy ideas into something legible.
• Loves talking to users. You know how to run a good user interview—asking open questions, listening more than you talk, and pulling signal from what people do versus what they say.
