[Hiring] Staff Information Security Engineer @Rithum

Role Description

As a Staff AI-First 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 vague AI risks into concrete, enforced guardrails.

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

• Platform Engineering
• IT
• Security Champions
• External auditors

Responsibilities

• Act as the bridge between architectural intent and operational reality.
• Mediating conflicts between security requirements and feasible implementation.
• Proposing compensating controls where gaps exist.
• Helping register, track, and remediate residual risks.
• Implementing preventive, default-on security controls across cloud and enterprise environments.
• Codifying security controls as policy- and infrastructure-as-code.
• Implementing and enforcing identity and access controls to an agreed standard.
• Assisting in maintaining the InfoSec risk register.
• Tracking emerging threats and translating them into actionable guidance for engineering teams.
• Supporting third-party and vendor risk assessments.
• Automating repetitive security workflows.
• Building or operating AI-assisted security agents.
• Integrating security tooling with LLM layers.
• Defining and enforcing security requirements for AI-powered features.
• Conducting threat modelling on agentic and LLM-based systems.

Qualifications

• 5+ years of security engineering experience with demonstrated AI/ML security depth.
• Experience using AI tools and LLM frameworks and APIs.
• Hands-on identity and access expertise across modern enterprise and cloud identity stacks.
• Infrastructure and policy-as-code proficiency.
• Cloud security expertise.
• Application security and threat-modelling methodologies experience.
• Working knowledge of SOC 2 and/or ISO 27001 control frameworks.

Preferred Qualifications

• Experience building or operating AI agents in a production environment.
• Awareness of privacy regulation as it touches AI.
• Red teaming or adversarial ML research backgrounds.
• Experience implementing privileged-access, key-management, or data-protection programs.
• Experience with EDR, CASB, DLP, and security automation tools.
• Cloud Architecture or Security certifications.

Travel Required

• Up to 10%
