[Hiring] Staff Information Security Engineer @Rithum

Role Description

As a Staff Information Security Engineer, you own the intersection of AI adoption and information security:

• Designing guardrails for AI-powered products.
• Building automated security tooling.
• Designing security controls and monitoring for an AI-First workforce.
• Helping every team at Rithum move fast without creating unseen risks.

This is not a typical security role. You spend as much time building and automating as you do reviewing:

• Turning a repeating control into infrastructure-as-code.
• Transforming a manual review into a workflow.
• Converting a vague AI risk into concrete, enforced guardrails.

You work autonomously, balancing research with fast-paced delivery, and collaborating closely with:

• Platform Engineering
• IT
• Security Champions
• External auditors

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, etc.) and LLM frameworks and APIs (OpenAI, Anthropic, LangChain, or similar).
• Hands-on identity and access expertise across modern enterprise and cloud identity stacks.
• 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.
• Application security (OWASP Top 10 and the OWASP LLM/GenAI Top 10, secure SDLC) and threat-modelling methodologies (STRIDE, PASTA, or equivalent).
• Working knowledge of SOC 2 and/or ISO 27001 control frameworks.

Requirements

• Experience building or operating AI agents in a production environment.
• Awareness of privacy regulation (GDPR/CCPA) as it touches AI.
• Red teaming or adversarial ML research backgrounds.
• Experience implementing privileged-access, key-management, posture-management, or data-protection programs.
• Experience with EDR, CASB, DLP, Security automation and SAST, DAST, IAST and SCA tools.
• Cloud Architecture or Security certifications (CCSK, TAISE, AWS).

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.
