Details

Anthropic is building Claude Science, an AI workbench that gives researchers a single environment for literature, specialized databases, scientific computing, analysis, and publication-ready outputs. The platform already renders protein structures, genome tracks, and chemical structures natively, and coordinates multi-agent workflows with built-in review for citation and calculation errors. Much of the product is being built from 0 to 1, giving this role ownership over both product direction and architecture.

The successful candidate will be a technical leader focused on the end-to-end researcher experience, working directly with Anthropic's internal research team to bring model capabilities into production and shape the product roadmap.

Responsibilities

Ship quickly against a roadmap while helping define the product direction for a new category.
Interface directly with working scientists, including academic labs, industry research and development teams, and research institutes.
Translate customer and domain-expert insights into engineering priorities.
Partner with product and design to turn scientific workflows—from hypothesis through analysis and publication—into shipped product experiences.
Work closely with research teams to improve models' scientific capabilities.
Shape evaluations, identify failure modes, and feed real-world user findings back into model development.
Drive cross-team alignment and ship impactful work through influence and technical leadership.

Requirements

8 or more years of software engineering experience.
Ideally, 2 or more years at a Staff or equivalent technical leadership level.
Experience building products from 0 to 1 in fast-moving environments.
Ability to set technical direction with limited precedent.
Experience building AI products and turning model capabilities into applications that people use.
Comfort working directly with technical domain experts and translating their needs.
Bachelor's degree or an equivalent combination of education, training, and experience.
A field of study relevant to the role, demonstrated through coursework, training, or professional experience.

Preferred Qualifications

Background in chemistry, biology, physics, or another scientific discipline.
Experience working with research teams to improve domain-specific model capabilities, including evaluation frameworks.

Compensation

Annual salary: $405,000–$485,000 USD.
