Supplier Security & Assurance, Security GRC

Anthropic•San Francisco, CA

About The Position

Anthropic's Supplier Security & Assurance (SSA) team, part of Security GRC, is responsible for evaluating the security posture of suppliers. This involves assessing whether vendors meet Anthropic's security requirements, identifying any deviations, and providing clear approval decisions. The team assesses a wide range of vendors critical to a frontier AI lab, including SaaS and software providers, human data operations, compute and data center operators, hardware suppliers, and service firms. The program is designed to be agent-first, allowing human experts to focus on critical judgment, remediation efforts, and high-priority vendors. As a member of the SSA team, you will manage supplier security assessments from start to finish. This includes reviewing evidence, validating agent-generated evaluations, determining inherent and residual risk, and working with vendors and internal business owners to close findings. You will also be involved in post-approval assurance activities such as contractual security terms, secure configuration baselines, continuous monitoring, and reassessments. Additionally, you will contribute to shaping the program's tooling and requirements.

Requirements

Experience running supplier security assessments end to end at a technology company: scoping the engagement, determining inherent risk, reviewing controls and evidence, documenting residual risk, and driving findings to closure
Working knowledge of risk fundamentals (inherent and residual risk, control effectiveness, compensating controls, risk acceptance) and the judgment to apply them when the evidence is incomplete or the answer isn't in a framework
Ability to assess a vendor across security domains, and to recognize which findings you can close yourself and which need a security domain specialist
Track record of driving risk treatment to closure through influence across teams with competing priorities
Experience building or tuning an LLM-backed workflow, agent, or automation in a risk, compliance, or operations context, including tuning prompts and reviewing model output for accuracy
Experience building or operating issue management workflows: logging issues with a clear owner and due date, tracking remediation, and escalating when treatment stalls
Working technical knowledge of SaaS security configuration (SSO and SCIM, admin scoping, sharing defaults, audit log export) and of standard vendor security contract terms (DPA, incident notification, subprocessors, audit and testing rights)
Ability to read a SOC 2 report or penetration test and turn it into findings: identify control exceptions and carve-outs, map complementary user entity controls, and judge what the evidence does and does not prove

Nice To Haves

Experience assessing cloud infrastructure, data center, or data-pipeline vendors
Experience supporting SOX, SOC 2, or ISO 27001 third party or vendor management controls
Experience assessing additional, more specialized vendor cohorts from a security risk perspective: human data operations or data labeling vendors, hardware suppliers, compute providers and neoclouds, and others
Experience with post-approval supplier continuous monitoring: configuration, data, and use case drift detection, shadow IT & SaaS detection, vendor incident management, or evidence-based vendor audits/site visits

Responsibilities

Run supplier security assessments: review agent-prefilled outputs, evaluate vendor controls and evidence, determine residual risk, route to domain reviewers where deeper assessment is warranted
Operate supplier issue management and risk treatment: document each finding with a severity, an owner, and a due date, drive remediation with the vendor and the business owner, record risk acceptances, and roll open issues up to the risk register
Run continuous monitoring after approval: reopen an assessment on defined triggers (data classification change, new SOC 2 report, new subprocessor, vendor incident), investigate SaaS configuration, data, and use case drift signals, and queue a reassessment where the vendor's scope has moved
Improve the program as you run it: identify gaps in coverage, questionnaires, requirements, and tooling that surface during assessments, propose the fix, and carry roadmap items that mature supplier security overall
Tune and maintain our Claude-powered assessment platform alongside the team: prompt development, questionnaire and assessment type design, calibration against assessor decisions, and output QA
Contribute to KPI and KRI reporting on coverage, cycle time, residual risk, open issues, and reassessments due
