Anthropic Security Engineer jobs

Security engineers secure the systems that train, serve and increasingly are Claude: identity and secrets, supply-chain and CI/CD hardening, sandboxing, firmware and BMC security, detection and response, red teaming, and AppSec for agentic and code-execution systems. Reqs skew Senior and Staff+, teams build LLM-driven tooling for their own work, and several reqs are remote-friendly, which is unusual for a lab this size.

The Security Engineering team owns authentication architecture for training infrastructure, cryptographic protection of model weights and training data, and the developer security program, with sub-areas in identity and secrets, supply chain, infrastructure security, secure frameworks, platform and hardware security, D&R, offensive security, threat intel, AppSec and GRC — 51 open reqs, titles skewing Senior and Staff+.
