First full-time security hire who owns and builds HUD's entire security program: securing APIs, cloud infrastructure, and data workflows, leading incident response, and driving SOC 2 compliance and customer trust. Core areas include product security, cloud/infrastructure security, detection & response, and compliance.
HUD's mission is to build reliable, fair and open infrastructure for AI data. We want data to be valuable for the people who create it and trustworthy for the labs that train on it. Our team is a quickly growing group of researchers, engineers and operators building the economy that shapes what AI will become. Backed by $16M from top VCs and YC (W25), our marketplace and platform are used by startups, Fortune 500 companies and frontier labs.
We’re looking for a Security Engineer to own and build HUD’s security program as our first full-time security hire. You will work closely with the rest engineering to secure our product, cloud infrastructure, data workflows, and internal systems. You’ll also lead incident response, SOC 2, and customer trust.
We are securing up to billions in data assets and are looking for someone who can lead security such that our infrastructure is never compromised.
Lead detection and incident response from signal to alert to postmortem
Own HUD’s security roadmap across product security, cloud and infrastructure security, corporate security, incident response, and compliance
Secure HUD’s APIs, platform, and data systems through threat modeling, design and code reviews, authentication and authorization controls, secrets management, etc.
Build monitoring, detection, and incident-response capabilities; lead investigations and postmortems; and turn incidents and emerging threats into durable improvements
Own SOC 2 and customer trust, including control design, security questionnaires, policy management, vendor reviews, and audits
Partner with legal, commercial, engineering, and operations to translate customer contracts and data-license requirements into enforceable controls for data access, provenance, permitted use, retention, deletion, isolation, and auditability
You may be a good fit if you have:
Strong security engineering fundamentals and hands-on experience across multiple areas such as infrastructure security, detection and response, identity, etc.
Experience leading security incidents end-to-end, from detection and containment through root-cause analysis and follow-up engineering work
Experience implementing or operating SOC 2 or a comparable security framework, including translating requirements into real technical and operational controls
High agency and sound judgment—you can identify and prioritize the risks that matter, make pragmatic decisions under uncertainty, and personally drive implementation
Strong communication skills for working with founders, engineers, operations, legal, auditors, customers, and external partners
Strong candidates may also:
Experience as an early security hire or building a security program from scratch at a fast-growing startup
Experience securing AI/ML infrastructure, agent execution environments, data platforms, developer tools, or other systems that run untrusted code or process sensitive data
Experience protecting licensed, proprietary, or customer-provided data and operationalizing contractual requirements around access, use, retention, and deletion
Experience finding CVEs, creating security tooling on GitHub, or with bug bounty programs
CVEs, or have created security tooling on GitHub, have conference talks, bug bounty history, or blog posts about incidents/something security related they've done that would also be good
OSCP, AWS Security Specialist, OSWE, CKS, or GIAC hands on certifications
We prioritize technical aptitude and learning potential over years of experience. Motivated candidates are encouraged to apply even if they don't meet all criteria.
