Senior Product Designer, Boltz Lab

About Boltz

Boltz is a public benefit company building the next generation of AI-powered molecular modeling tools to make biology programmable and accelerate drug discovery, while keeping frontier capabilities broadly accessible.

Boltz began as an MIT spin-out. Our founders built Boltz-1 at MIT, and it became the first fully open-source model to match AlphaFold 3's accuracy in predicting the 3D structure of biomolecular complexes.

We focus on two things

• Open foundation models. Boltz-1, Boltz-2, and BoltzGen are open models trusted by 100,000+ scientists across biotech and academia, and used in programs at every Top 20 pharma as well as leading agrichemical and industrial research organizations.
• Boltz Lab. Our commercial platform runs our latest models and design agents as reliable, production-grade tools built around real chemistry and biology workflows. Teams start from a target and a hypothesis, then generate, evaluate, and rank candidate molecules, while we provide the compute, infrastructure, and collaboration layer so their scientists can move faster.

The two feed each other: open-source adoption earns scientific credibility and community insight, and Boltz Lab turns that into real impact on our partners' discovery programs.

About the role

As Product Designer for Boltz Lab, you will own how scientists experience, trust and use our AI for molecular modeling and drug discovery. Our models are powerful but complex; design is what makes them usable, and trustworthy, for researchers who aren't ML experts.

You will work closely with Product engineering, ML Research and our chemistry and biology experts to turn user needs into clear concepts, interaction patterns and end-to-end workflows.

This role is ideal for someone who enjoys technically deep products, cares about craft and usability, and wants to build tools that expand what scientists can do.

What you'll do

• Own Boltz Lab's design end to end, from discovery and user research through prototyping, visual design and engineering handoff.
• Define the product's information architecture, interaction model and visual language, and keep them consistent as it grows.
• Design interfaces for exploring data, configuring models, interpreting results and iterating on experiments.
• Make ML outputs interpretable and actionable, so users can judge when to trust a result.
• Run research and usability testing with expert users, and feed what you learn back into the product and roadmap.

About you

Minimum Requirements

• 6+ year of experience designing complex, data-rich products for technical or expert users.
• Excellent interaction design, information architecture and visual design, with strong prototyping in modern tools (e.g. Figma).
• Ability to turn abstract or highly technical concepts into intuitive, well-structured experiences.
• A track record of owning product design end to end, from discovery to shipped product.
• Close collaboration with engineers and researchers, and clear communication of design decisions and trade-offs.

Preferred Requirements

• Basic understanding of biology, chemistry, drug discovery or ML workflows.
• Experience designing for scientific, research or developer tools, or owning design direction at an early-stage startup.
• Experience using Boltz models, or usability testing with expert users.

We know great people don't always tick every box. If this role excites you and you meet most of the minimum requirements, we'd like to hear from you.

What we offer

• Ownership of the design of Boltz Lab, used by leading discovery teams.
• Work alongside one of the most talent-dense teams in the field.
• Significant ownership and independence, with responsibility for driving projects from concept to deployment.
• Highly competitive salary with meaningful equity in a public benefit company.
• Benefits:
• 25 days annual leave plus bank holidays
• Annual team offsite trip
• Private healthcare (BUPA), covering pre-existing conditions
• Pension program
• Paid parental leave
• Wellhub gym membership
• Free lunch every day
• Travel expenses
