## Description

## 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.

## About the role

We're hiring a Staff + Software Security Engineer for our Security Labs team. This team works on high-risk, high-expected-value security projects that require breakthroughs and innovative thinking. You'll work on projects that seem impractical until someone optimistic and stubborn enough actually tries it.

The current project areas include:

- Standing up a prototype high-assurance research cluster

- Provable inference: cryptographic verification

- Build hypervisor-isolated microVM workload isolation

- Compiling an ML kernel through a formally verified pipeline

- Regenerating clusters: automation that spins up a purpose-built cell

- Using Claude itself to drive security work end to end

## Key Responsibilities

- Own Security Labs projects end to end

- Stand up novel security infrastructure fast

- Find the receiving team early and bring them along while you build

- Work embedded with research and infrastructure teams

- Turn experimental results into short writeups

- Help pick the next round of bets and influence the industry

## Minimum Qualifications

- Genuinely care about where AI is heading and want to work on the security problems

- Have real depth in at least one area most software engineers don't touch

- Have built and shipped things under your own direction

- Have a track record of choosing the problem yourself and seeing it through

- Are comfortable jumping between domains and layers of the stack

- Write clearly enough to turn weeks of work into a couple of pages

- Change your mind when the evidence says to

- Care about defense

- Are a strong programmer (Python plus at least one of Rust, Go, or C/C++)

## Preferred Qualifications

- Experience inside airgapped or high-side environments

- A background in offensive security, red teaming, or vulnerability research

- Familiarity with ML infrastructure

- A history of working in environments built around rapid iteration

## Logistics

- Annual Salary: $320,000-$485,000 USD

- Minimum education: Bachelor’s degree or an equivalent combination of education, training, and/or experience

- Required field of study: A field relevant to the role

- Minimum years of experience: Correlate with internal job level requirements

- Location-based hybrid policy: At least 25% of time in one of our offices

- Visa sponsorship: We do sponsor visas
