Staff Information Security Engineer - AI First

Staff Information Security Engineer - AI First

Strong AI-first focus — integrates LLMs and AI assistants into security tooling and builds AI-assisted security agents with human-in-the-loop controls.

About the Role

Rithum is hiring a Staff Information Security Engineer focused on securing AI adoption across products and operations. The role designs and implements preventive, policy- and infrastructure-as-code security controls, automates security workflows and integrates LLMs/AI into security tooling to enable safe, scalable AI usage across the company.

Job Description

Role

Rithum seeks a Staff AI-First Information Security Engineer to own the intersection of AI adoption and information security. You will design guardrails for AI-powered products and workforce use, build automated security tooling, codify controls as policy- and infrastructure-as-code, and enable fast, low-risk AI usage across engineering and platform teams.

Key Responsibilities

• Bridge architectural intent and operational reality; propose compensating controls and manage residual risk tracking and remediation.
• Implement preventive, default-on security controls across cloud and enterprise environments, codified as policy- and infrastructure-as-code.
• Implement and enforce identity and access controls, including access boundaries for AI systems and non-human/agent identities.
• Maintain the InfoSec risk register; track emerging threats and translate them into actionable guidance.
• Support third-party/vendor risk assessments with emphasis on vendors processing data through AI pipelines.
• Automate repetitive security workflows (evidence collection, access reviews, alert enrichment) and build/operate AI-assisted security agents with human-in-the-loop gates and least-privilege credentials.
• Integrate security tooling (SIEM, CSPM, DAST/SAST, vulnerability scanners) with LLM layers to surface actionable insight and automated response.
• Define and enforce security requirements for AI features: model access controls, prompt-injection mitigations, output validation, and data-handling boundaries.
• Conduct threat modeling for agentic and LLM-based systems, addressing novel attack surfaces like tool misuse, indirect prompt injection, and supply chain risk.

Qualifications

Minimum Qualifications

• 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) and LLM frameworks/APIs (OpenAI, Anthropic, LangChain) to accelerate work.
• Hands-on identity and access expertise across modern enterprise and cloud identity stacks, including access models for AI and non-human identities.
• Experience with infrastructure and policy-as-code (e.g., Terraform, OPA/Rego) and proficiency in a scripting language for automation (Python preferred).
• Cloud security expertise (AWS-focused experience/certification or equivalent), including multi-account governance and preventive guardrails.
• Application security knowledge (OWASP Top 10, OWASP LLM/GenAI Top 10), secure SDLC, and threat-modeling methodologies (STRIDE, PASTA, or equivalent).
• Practical experience building or operating AI agents and integrating security tooling (SIEM, CSPM, SAST/DAST/SCA) for actionable outputs.
• Working knowledge of SOC 2 and/or ISO 27001 control frameworks.

Preferred Qualifications

• Production experience building or operating AI agents.
• Awareness of privacy regulations affecting AI (GDPR/CCPA), privacy-by-design, and DPIAs.
• Red teaming or adversarial ML research experience.
• Experience implementing privileged-access, key-management, posture-management, or data-protection programs.Experience with EDR, CASB, DLP, security automation, and SAST/DAST/IAST/SCA tools.Cloud architecture or security certifications (e.g., CCSK, TAIS E, AWS certifications).

  Compensation & Travel

  • Expected base pay range (U.S.): $170,000 - $220,000 per year.
  • Expected discretionary bonus: 12% of annual base salary.
  • Travel: Up to 10%.
