## Job description

## 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-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. We deliver these capabilities through Boltz Lab, our platform for running our latest models and design agents as reliable, production-grade tools. Boltz Lab is designed around real chemistry and biology workflows, so teams can start from a target and a hypothesis and quickly generate, evaluate, and rank candidate molecules. We provide the compute, the scalable infrastructure, and the collaboration layer, so scientists can iterate faster and stay focused. You can read more about our mission, research and product vision on our [manifesto](http://boltz.bio/manifesto).

## About the role

As a Product Designer, you will own the design of Boltz Lab, shaping how scientists experience, trust, and use cutting-edge AI for molecular modeling and drug discovery. Your role is to turn powerful but complex capabilities into intuitive, trustworthy, and delightful product experiences for researchers in drug discovery. You’ll work closely with software engineers, ML researchers, and domain experts in chemistry and biology to understand user needs and translate them into clear product concepts, interaction patterns, and end-to-end workflows. This includes designing interfaces for exploring data, configuring models, interpreting results, and iterating on experiments. You will own the design process from early discovery and user research through prototyping, visual design, and implementation handoff. You’ll help define the product’s information architecture, interaction models, and visual language, ensuring consistency, usability, and clarity across Boltz Lab. A key part of the role is making advanced ML outputs interpretable and actionable, helping users build confidence in model behavior and results. This role is ideal for a designer who enjoys working on technically deep products, cares deeply about craft and usability, and is motivated by building tools that expand what scientists can do.

## About you

Essentials:

- Strong experience designing complex, data-rich products or tools used by technical or expert users.
- Proven ability to own end-to-end product design, from discovery and user research through interaction design, visual design, and engineering handoff.
- Excellent skills in interaction design, information architecture, and systems thinking, with an eye for clarity and usability in complex workflows.
- Ability to translate abstract or highly technical concepts into intuitive, well-structured user experiences.
- Strong visual design and prototyping skills, with experience using modern design tools (e.g. Figma or equivalent).
- Experience collaborating closely with software engineers and product stakeholders, incorporating feedback while maintaining a high bar for design quality.
- Clear communication skills, with the ability to explain design decisions and trade-offs to both technical and non-technical audiences.

Nice to have:

- Experience designing products for scientific, engineering, or research-driven domains (e.g. biotech, ML tooling, data platforms, developer tools).
- Familiarity with workflows in machine learning, data science, or computational research.
- Experience designing interfaces for data exploration, experimentation, or analysis-heavy workflows.
- Experience working at an early-stage startup or owning large parts of a product’s design direction.
- Exposure to usability testing with expert users and iterating based on qualitative feedback.
- Interest in or basic understanding of biology, chemistry, or drug discovery.

## What we offer

- Opportunity to drive outsized real-world impact by building tools that empower thousands of scientists across the industry.
- 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 substantial equity ownership.

## About Boltz

## Company Overview
- **One-liner**: Boltz builds foundational AI models and a platform for biomolecular modeling and design, enabling scientists to engineer proteins and small molecules for drug discovery.
- **Entity Type**: Private (Seed stage; raised $28M)
- **Headquarters**: London, United Kingdom (also has an office in Boston, Massachusetts, USA)
- **Founded**: 2025
- **Founders**: Not publicly available (the company originated from research at MIT)

## Core Business
- **Primary industry/industries**: Artificial intelligence for biology and chemistry; biotechnology research
- **Target customers**: B2B – pharmaceutical companies (including all top 20 pharma), biotech startups, academic labs, and individual scientists
- **Mission or purpose statement**: To advance the frontier of AI capabilities in biology through open science and make them universally accessible to every scientist working toward a healthier, more sustainable future. Boltz is a Public Benefit Corporation (PBC).

## Products & Services
- **Boltz-1 / Boltz-1x**: Open-source structure prediction models approaching AlphaFold3-level accuracy; commercially usable under a permissive license.
- **Boltz-2**: Frontier structure prediction model that pushes binding affinity prediction to unprecedented accuracy using large-scale supervision.
- **BoltzGen**: A protein design model and agent capable of generating binders to arbitrary targets, validated across diverse modalities, targets, and assays.
- **Boltz Lab**: A cloud platform (in beta) providing hosted compute, agentic workflows for small-molecule discovery and protein design, collaborative interfaces, and enterprise deployments (multi-tenant, single-tenant, or on-premise). SOC 2 Type 1 verified. Usage-based pricing with generous free tiers.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: $28M in total seed funding (1 prior round)
- **Notable Investors/Partners**: Amplify, a16z, Zetta (co-leads); angel investors include Clement Delangue (CEO of Hugging Face), Factorial Capital, Obvious Ventures. **Key partnership**: multi-year agreement with Pfizer to deploy Boltz Lab across the company and co-develop new foundation models.
- **Growth Signals**: 5M+ downloads, 100k+ scientists using the models, adoption by all top 20 pharma companies and thousands of biotechs. Rapidly expanding team (hiring research engineers, software engineers, product designers, protein engineers).

## Competitive Advantages
- **Open‑source foundation**: Permissively licensed models (Boltz-1, Boltz-1x) that have been validated by the community, lowering the barrier to entry and building trust.
- **Performance and cost**: Claims the lowest price per unit of any major provider in the space; optimized models reduce compute costs.
- **IP protection**: Customers own their outputs, data stays secure, and Boltz does not train on customer data. Offers on-premise deployment for sensitive work.
- **Public Benefit Corporation**: Mission‑aligned structure that explicitly avoids competing with customers (Boltz does not develop drugs itself).

## Strategic Focus
- **Three pillars**: Research (understand and reprogram biology from the bottom up), Product (put powerful AI into scientists’ hands via agentic workflows and eventually autonomous labs), Community (open science and broad accessibility).
- **Current priorities**: Expanding the Boltz Lab platform, fine‑tuning models on proprietary customer data, building agents for new modalities, and scaling enterprise partnerships.

## Why Work Here
- **Culture**: Mission‑driven, open‑science ethos with a strong emphasis on research excellence and product impact. The team is lean (~17 employees as of early 2026) and growing.
- **Remote/Hybrid**: Not explicitly stated; locations include London (HQ) and Boston. Likely flexible given the global team (employees in UK, US, Netherlands, Switzerland).
- **Notable perks**: Opportunity to work on frontier AI models used by 100k+ scientists; direct collaboration with top pharma; usage‑based pricing aligns with customer success; public‑benefit status ensures long‑term mission alignment.
- **Engineering culture**: Heavy focus on research engineering, software engineering, and product design. Looking for protein engineers with preclinical experience to shape the product roadmap.
