📋 Description

• Act as the bridge between architectural intent and operational reality; mediate conflicts between security requirements and feasible implementation, propose compensating controls where gaps exist and help register, track and remediate residual risks. • Implement preventive, default-on security controls across cloud and enterprise environments, codified as policy- and infrastructure-as-code so security is enforced by design, including controls that govern how AI tools and models may be used. • Implement and enforce identity and access controls to an agreed standard, including access boundaries for AI systems and non-human/agent identities by partnering with Platform Engineering and IT to align tooling and policy to the architecture. • Assist in maintaining the InfoSec risk register; track emerging threats and translate them into actionable guidance for engineering teams. • Support third-party and vendor risk assessments, with a focus on vendors who process data through AI pipelines. • Automate repetitive security workflows (evidence collection, access reviews, alert enrichment) and build or operate AI-assisted security agents — with human-in-the-loop approval gates, least-privilege credentials, and explicit attention to each agent's own blast radius. • Integrate security tooling (SIEM, CSPM, DAST/SAST, vulnerability scanners) with LLM layers to surface actionable insight and automated responses. • Define and enforce security requirements for AI-powered features: model access controls, prompt-injection mitigations, output validation, and data-handling boundaries. • Conduct threat modelling on agentic and LLM-based systems, accounting for novel attack surfaces such as tool misuse, indirect prompt injection, and supply chain risk.

🎯 Requirements

• 5+ years of security engineering experience with demonstrated AI/ML security depth (prompt injection, model supply chain, adversarial inputs, RAG). • Experience using AI tools (ChatGPT, Copilot, Claude, etc.) and LLM frameworks and APIs (OpenAI, Anthropic, LangChain, or similar) to accelerate and elevate your work. • Hands-on identity and access expertise across modern enterprise and cloud identity stacks, including access models for AI systems and non-human identities. • Infrastructure and policy-as-code (e.g. Terraform, OPA/Rego) and proficiency in a scripting language for automation (Python preferred). • Cloud security expertise: AWS Solutions Architect / Security Specialty or equivalent demonstrated expertise, including multi-account governance, preventive guardrails, and policy-as-code. • Application security (OWASP Top 10 and the OWASP LLM/GenAI Top 10, secure SDLC) and threat-modelling methodologies (STRIDE, PASTA, or equivalent). Practical experience building or operating AI agents, and integrating security tooling (SIEM, CSPM, SAST/DAST/SCA) so it surfaces action rather than raw alerts. • Working knowledge of SOC 2 and/or ISO 27001 control frameworks

🏖️ Benefits

• Medical, dental and vision benefits: Affordable health care plans and company HSA contributions, starting on Day 1 • A 6% 401(k) match • Competitive time off package with 20 days of Paid Time Off, 9 Company-Paid holidays, 2 paid floating holidays, 7 paid sick days, 2 Wellness days, and 1 Paid Volunteer Day; at 3 years of service PTO increases to 22 days, and at 5 years it increases to 25 days • 12 weeks primary caregiver leave & 4 weeks secondary caregiver leave • Accident, critical illness, and hospital indemnity insurance • Pet insurance • Legal assistance and identity theft insurance plans • Life insurance 2x salary • Access to the Calm app and the Employee Assistance Program • $65/month Remote work stipend for internet • Culture and team-building activities • Tuition assistance • Career development opportunities • Charitable contribution match up to $250 per year
