Job Description

Today, more than 40,000 companies trust Rithum to grow their business across hundreds of channels, representing over $50 billion in annual GMV.

Overview Rithum expects employees across all roles to leverage AI and technology to improve efficiency, streamline workflows, and create scalable ways of working. Rithum is embedding AI into every corner of how it operates - and security is no exception.

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, a manual review into a workflow, and a vague AI risk into a concrete, enforced guardrails.

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.

Key Responsibilities

• Rithum™ is the world’s most trusted commerce network, accelerating how brands, suppliers, and retailers work together to deliver seamless e-commerce experiences.
• Using our commerce, marketing, and delivery solutions, our customers create optimized consumer shopping journeys from beginning to end.
• 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 risk they cannot see.
• You spend as much time building and automating as you do reviewing, turning a repeating control into infrastructure-as-code, a manual review into a workflow, and a vague AI risk into a concrete, enforced guardrails.
• You work autonomously, balancing research with fast-paced delivery, and collaborating closely with Platform Engineering, IT, Security Champions, and external auditors.
• Responsibilities 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.
• 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.
