About the job

At Compass, our mission is to help everyone find their place in the world. Founded in 2012, we’re revolutionizing the real estate industry with our end-to-end platform that empowers residential real estate agents to deliver exceptional service to seller and buyer clients.

Engineering @ Compass

Compass has built the first modern end-to-end real estate platform by integrating agents, buyers and sellers through technology. Until Compass, no one has achieved the blend of the Natural Intelligence that hundreds of thousands of enterprising real estate agents bring to this market, with the “Artificial Intelligence” that cloud, mobile and AI technologies enable. We are building AI to empower AI - Artificial Intelligence to empower Agent Intelligence.

As one of the fastest growing technology companies of our generation, in an industry larger than any other, we have an opportunity and obligation to build a world-class engineering team and the operating platform that will transform real estate.

Security @ Compass

We are hands-on security engineers helping to build secure, resilient, and scalable web apps, mobile apps, and platforms for the real estate industry. We work with a diverse set of teams to provide transparent and automated security tooling and services. We architect secure products, perform simulated attacks, identify weaknesses, and partner with teams to remediate and protect.

The Role

Compass is embedding generative and agentic AI directly into the products our agents and clients use every day. This role owns the security of that surface. You will be the technical authority on how Compass builds AI features safely, from the model and retrieval layer, through agent tool invocation, to what ultimately reaches a client's screen. You will work shoulder-to-shoulder with the teams building the AI platform so that platform standards and security standards are one bar, not two.

What You Will Do

Own the AI product security roadmap. Define the multi-year vision, strategy, and standards for securing AI capabilities in the Compass platform, developed jointly with the AI platform and product engineering teams.

Threat model AI capability builds. Drive architectural reviews and threat modeling for new AI features, RAG pipelines, multi-agent workflows, and automated decisioning before they ship.

Build production guardrails. Architect, deploy, and automate real-time protections for LLM inputs and outputs, including injection mitigation, jailbreak defense, output verification, and sensitive-data egress checks on generated responses.

Constrain autonomy. Design blast-radius controls for autonomous agents: scoped permissions, human-in-the-loop checkpoints for consequential actions, action audit trails, and safe tool-invocation patterns.

Secure the retrieval layer. Enforce data access controls, source integrity, tenancy boundaries, and retrieval-boundary protections across RAG and vector store implementations.

Harden the AI supply chain. Assess the security posture, privacy controls, data retention, and training-use terms of third-party foundation models, inference providers, and vector stores used in production.

Instrument and detect . Build detections and telemetry for AI-specific abuse in production, anomalous tool invocation, prompt abuse patterns, unusual retrieval behavior, and data exfiltration through model responses and integrate them into our monitoring estate.

Automate the standard. Ship reusable libraries, CI/CD checks, and evaluation harnesses so secure AI patterns are the default path for product engineers rather than a review gate.

Advise and evangelize. Act as the primary technical consultant for AI architecture decisions and translate emerging AI risk into concrete engineering roadmaps for both engineers and executives.

Who You Are

Automation is your default approach to security, especially when securing complex AI systems at scale.

You have a deep working understanding of transformer architectures, inference pipelines, RAG, prompt engineering, and the OWASP Top 10 for LLMs.

You write production code, strong proficiency in Python or Go, with experience building real integrations and security pipelines, not just prototypes.

You are proactive about finding and closing gaps in AI/ML workflows through tooling rather than policy.

You communicate well across audiences, translating emerging AI risk into technical roadmaps for engineers and business impact for leadership.

Minimum Qualifications

7+ years in security engineering, with 2+ years focused on AI/ML or LLM application security.

Demonstrated experience securing a production AI or ML system end to end, development lifecycle, deployment, and runtime.

Expertise in adversarial ML and LLM risks including prompt injection, model poisoning, data extraction, and unsafe tool use, with hands-on red teaming experience.

Strong application and cloud security fundamentals: AWS and/or GCP, Kubernetes, IAM, API security, and DevSecOps practices.

Experience threat modeling complex distributed systems and driving remediation with engineering teams.

Strong strategic communication skills with a proven ability to translate complex technical AI risk into business impact for executive leadership.

Nice to Have

Experience with multi-agent autonomous systems or Model Context Protocol (MCP) based architectures.

Familiarity with MITRE ATLAS, NIST AI RMF, or comparable AI threat/risk frameworks.

Background building evaluation and safety-testing harnesses for LLM applications.

Experience in a regulated or consumer-data-heavy environment where model outputs touch customer-facing decisions.

Prior work on AI platform security architecture or secure-by-default AI SDKs.
