Senior+ Software Engineer, Legal Tech

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 Legal Tech engineers play a specialized and critical role in keeping Claude at the frontier. Partnering closely with counsel, we provide custom infrastructure and guidance for complex, novel technical matters, empowering teams across the company to continue meeting our legal obligations as we innovate.

As a Senior+ Software Engineer on our Legal Tech team, you'll build dedicated, highly secure, and reliable cloud environments and data processing and storage capabilities at speed and scale. You will own your scope end to end: from raw requirements all the way through to large-scale production systems that satisfy legal invariants and unlock new possibilities. The systems you build won't just be dependable and scalable; they'll be interpretable and auditable, demonstrating to skeptical audiences exactly how they worked and why results can be trusted.

You'll be an essential member of a collaborative team, working together to solve difficult problems against fixed deadlines. You will own internal customer relationships as well: you'll gather, prioritize, and coordinate needs from colleagues on Privacy, Security, Research, and/or Infra as well as Legal, to ship the right capabilities on the right timelines. You'll act as a trusted advisor: clearly explaining technical concepts and constraints to inform legal decisions, and proactively designing new approaches to prevent classes of problems. Your infrastructure expertise will directly empower our business to calibrate and manage risk, innovating faster thanks to systems that build in legal considerations.

Key responsibilities

Build and operate dedicated cloud infrastructure, storage, and data pipelines for specialized workloads that can't run on general-purpose systems

Design architectures with excellent security, privacy, reliability, scalability, and auditability baked in

Partner with a wide range of internal customer teams to translate requirements into sound approaches and realistic ETAs

Deliver against fixed deadlines

Support complex and novel legal requests on controlled infrastructure, with verifiable chain of custody

Pair with engineering teams across the company to extend existing infrastructure to support new workflows and/or legal requests

Work with nontechnical stakeholders to clarify their needs through responsive, easy-to-follow dialogue

Minimum qualifications

Experience designing, building, and operating highly trusted infrastructure and data systems in production, including owning architectural decisions

Experience working across large, complex, multi-team environments, including in stacks and code you don't own

Ability to take ownership of a cloud account and secure it end to end (networking, storage, identity, encryption, least-privilege provisioning, etc.) on AWS and/or GCP

Ability to translate legal and privacy requirements into sound technical designs and implementations that teams are excited to adopt

A habit of verifying rather than assuming: designing checks for invariants and plainly naming what isn't proved

Self-directed in a high-change environment, and comfortable resequencing quickly when new needs emerge

Clear communication with nontechnical stakeholders, and an understanding of their needs

Preferred qualifications

Software engineering experience with an infrastructure, data, privacy, and/or security focus

Proficiency with large-scale data tooling, such as distributed processing, lakehouse table formats, and/or query engines

Understanding of data processing pipelines, LLM training, and/or provenance and lineage

Experience with secure enclaves, confidential computing,...
