In the posting’s own words

Claude Science is an AI workbench that gives researchers a single environment for work that today spans dozens of disconnected tools — literature, specialized databases, scientific computing, analysis, and publication-ready outputs. Claude Science already renders protein structures, genome tracks, and chemical structures natively, and coordinates multi-agent workflows with built-in review for citation and calculation errors — and we’re just getting started. Much of this is being built 0→1 right now: you’ll shape both the product and the architecture in a category no one has defined yet.

What it asks for · 5

  • Have 8+ years of software engineering experience, ideally with 2+ years at a Staff or equivalent technical leadership level
  • Have built products from 0 to 1 in fast-moving environments, and can set technical direction with limited precedent to lean on
  • Have built AI products and know what it takes to turn model capabilities into applications people actually use
  • Are comfortable working directly with technical domain experts and translating what you learn
  • Drive cross-team alignment to ship impactful work, with influence over authority

Also a plus

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

What the job covers

  • Ship fast against a roadmap you help shape: this is a product in a category no one has defined yet, and the highest-leverage problems are still unclaimed
  • Interface directly with working scientists — academic labs, industry R&D teams, and research institutes — during key conversations, translating what you learn into engineering priorities
  • Partner with product and design to turn how scientists actually work — from hypothesis to analysis to publication — into shipped product
  • Work closely with research to make the models better at science: shaping evals, surfacing failure modes, and feeding what users hit in the real world back into model development

How this page was made

An automated read of a public job posting, fetched August 30, 2026 and last changed by Anthropic on August 21, 2026. Every list above is pulled from the posting’s own sentences — nothing rewritten, nothing added, no judgment about the role or the company. Counts and seniority are read off the text by rule, so they can be wrong where the posting is unusual. The original is the only thing that binds. Openings close without warning; check the source before spending an evening on it.
