Senior Software Engineer, Research Tools

About Anthropic

Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.

About the role

Anthropic's research teams are pushing the boundaries of AI safety and capability research, and they need exceptional tools to do their best work. As a Software Engineer on the Research Tools team, you'll build the infrastructure and applications that enable our researchers to iterate quickly, run complex experiments, and extract insights from frontier AI systems.

This role sits at the intersection of product thinking and full-stack engineering. You'll work directly with researchers and engineers to deeply understand their workflows, identify bottlenecks, and rapidly ship solutions that multiply their productivity. Whether you're building human feedback interfaces for model evaluation, creating platforms for experiment orchestration, or developing novel visualization tools for understanding model behavior, your work will directly accelerate our mission to build safe, reliable AI systems.

We're looking for someone who can operate with high agency in an ambiguous environment—someone who can be dropped into a research team, quickly develop domain expertise, and independently drive impactful projects from conception to delivery. No ML or Research experience is required

Responsibilities

Build and maintain full-stack applications and infrastructure that researchers use daily to conduct experiments, collect feedback, and analyze results

Partner closely with research teams to understand their workflows, pain points, and requirements, translating these into technical solutions

Design intuitive interfaces and abstractions that make complex research tasks accessible and efficient

Create reusable platforms and tools that accelerate the development of new research applications

Rapidly prototype and iterate on solutions, gathering feedback from users and refining based on real-world usage

Take ownership of complete product areas, from understanding user needs through design, implementation, and ongoing iteration

Contribute to technical strategy and architectural decisions for research tooling

Mentor other engineers and help establish best practices for research application development

You may be a good fit if you

Have 5+ years of software engineering experience with a strong focus on full-stack development

Excel at rapid iteration and shipping—you can move from concept to working prototype quickly

Have experience building tools, platforms, or infrastructure for technical users (engineers, researchers, data scientists, analysts, etc.)
