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.

Anthropic's Legal Tech engineers play a specialized and critical role in keeping Claude at the frontier by partnering closely with counsel.
The role involves building dedicated, highly secure, and reliable cloud environments and data processing and storage capabilities at speed and scale.
As a Senior+ Software Engineer, you will own your scope end to end to satisfy legal invariants and unlock new possibilities.

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

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 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
Bachelor's degree or an equivalent combination of education, training, and/or experience
A field of study relevant to the role as demonstrated through coursework, training, or professional experience

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, clean rooms, or other purpose-built environments for sensitive data
Background in eDiscovery, litigation support, or records retention at scale, including chain of custody and verifiable integrity

Location-based hybrid policy expecting staff to be in one of the offices at least 25% of the time, though some roles may require more time in offices
