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.\nEngineering @ Compass\nCompass 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.\nAs 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.\nSecurity @ Compass\nWe 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.\nThe Role\nCompass 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.\nWhat You Will Do\nOwn 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.\nThreat 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.\nBuild 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.\nConstrain 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.\nSecure the retrieval layer. Enforce data access controls, source integrity, tenancy boundaries, and retrieval-boundary protections across RAG and vector store implementations.\nHarden 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.\nInstrument 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.\nAutomate 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.\nAdvise 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.\nWho You Are\nAutomation is your default approach to security, especially when securing complex AI systems at scale.\nYou have a deep working understanding of transformer architectures, inference pipelines, RAG, prompt engineering, and the OWASP Top 10 for LLMs.\nYou write production code, strong proficiency in Python or Go, with experience building real integrations and security pipelines, not just prototypes.\nYou are proactive about finding and closing gaps in AI/ML workflows through tooling rather than policy.\nYou communicate well across audiences, translating emerging AI risk into technical roadmaps for engineers and business impact for leadership.\nMinimum Qualifications\n7+ years in security engineering, with 2+ years focused on AI/ML or LLM application security.\nDemonstrated experience securing a production AI or ML system end to end, development lifecycle, deployment, and runtime.\nExpertise in adversarial ML and LLM risks including prompt injection, model poisoning, data extraction, and unsafe tool use, with hands-on red teaming experience.\nStrong application and cloud security fundamentals: AWS and/or GCP, Kubernetes, IAM, API security, and DevSecOps practices.\nExperience threat modeling complex distributed systems and driving remediation with engineering teams.\nStrong strategic communication skills with a proven ability to translate complex technical AI risk into business impact for executive leadership.\nNice to Have\nExperience with multi-agent autonomous systems or Model Context Protocol (MCP) based architectures.\nFamiliarity with MITRE ATLAS, NIST AI RMF, or comparable AI threat/risk frameworks.\nBackground building evaluation and safety-testing harnesses for LLM applications.\nExperience in a regulated or consumer-data-heavy environment where model outputs touch customer-facing decisions.\nPrior work on AI platform security architecture or secure-by-default AI SDKs.\nThe base pay range for this position is $210,000 - $234,000; however, base pay offered may vary depending on job-related knowledge, skills, and experience. Bonuses and restricted stock units may be provided as part of the compensation package, in addition to a full range of benefits. Base pay is based on market location. Minimum wage for the position will always be met.\nPerks that You Need to Know About:\nParticipation in our incentive programs (which may include eligible cash, equity, or commissions). Plus paid vacation, holidays, sick time, parental leave, and recharge leave; medical, tele-health, dental and vision benefits; 401(k) plan; flexible spending accounts (FSAs); commuter program; life and disability insurance; Maven (a support system for new parents); Carrot (fertility benefits); UrbanSitter (caregiver referral network); Employee Assistance Program; and pet insurance.\nDo your best work, be your authentic self.\nAt Compass, we believe that everyone deserves to find their place in the world - a place where they feel like they belong, where they can be their authentic selves, where they can thrive. Our collaborative, energetic culture is grounded in ourCompass Entrepreneurship Principles and our commitment to diversity, equity, inclusion, growth and mobility.
