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 OverviewWe'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 ResponsibilitiesUser 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.
Operational backbone: Maintain roadmap, milestone trackers, and product documentation in Notion so the team can move fast.
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.
Genuine passion for building great products. You study the products you admire, play with new tools, and think about what makes them work.
Self-direction. You can take an ambiguous task, figure out a sensible approach, and come back with progress.
Creative and productive AI use. We aren't just looking for operators of AI; we use AI tools constantly in our work, and we believe the meaningful contribution is what we add on top.
Open to students, recent graduates, or career-changers looking to break into product. We're open to any background — folks coming from biology, chemistry, CS, engineering, or design are particularly well-suited, but what we care about most is how you think and what you've built.
Bonus: prior internship experience, side projects, or anything that shows you've shipped something real.
Given the cross-disciplinary and innovative nature of our work, effective collaboration and communication are critical to our progress. We operate in a flexible hybrid model that accommodates both fully remote team members and those who work full-time from our Somerville, MA office. While some positions may require regular in-person presence for hands-on work or local collaboration, many roles can be performed remotely with team members distributed across various locations.
Compensation and BenefitsMatterworks offers full-time employees a competitive base salary, stock options, and benefits (health & dental, vision, long- and short-term disability, life insurance, 401k with company match). Employees enjoy a flexible work & unlimited time away policy, commuter benefits and parking, regular team meals and outings, and company support for continued education/coursework and conference participation.
