Security Lead, Product and Infrastructure (InfoSec)

Description

The company is building personal AI that each person owns and shapes. It is rebuilding the full stack, covering personal hardware for local inference, custom training infrastructure, new user interfaces, and deep learning research.

The team includes scientists and engineers from leading tech companies and AI labs, with experience scaling consumer systems to hundreds of millions of users and building pre-training infrastructure for frontier models.

This is a first security hire. The company is looking for a hands-on, technically strong security lead to build the security program from scratch and protect research infrastructure, model weights, corporate assets, and the customer platform while keeping frontier AI development moving quickly.

The role combines engineering leadership, program building, and strategy. You will build capabilities across cybersecurity, detection and response, product security, and operational security, and treat security as something that helps teams build rather than something that blocks them.

Responsibilities

• Build the security function from the ground up, designing and scaling the full operation: product and infrastructure security, detection engineering, incident response, governance, risk and compliance, and workplace security.
• Protect the most valuable assets: proprietary model weights, training data pipelines, research clusters, and source code, against skilled adversaries who target AI intellectual property.
• Create lightweight, automated controls and secure-by-default infrastructure so developers can experiment safely without slow, bureaucratic approval steps.
• Own corporate IT, identity and access management, and privacy engineering so that employees have a smooth and secure experience.
• Research and build tooling, including how AI can help with vulnerability discovery, code analysis, and defensive operations, and how products can be made more secure.
• Act as the external security contact for enterprise customers, regulators, board members, and government partners. Lead the compliance roadmap, including SOC 2, ISO 27001, and FedRAMP, to support commercial and public-sector sales.
• Recruit and mentor strong security engineers, operators, and researchers who automate repetitive work, build security into the software development lifecycle, and set high standards for the field.

Requirements

• At least 10 years in security, including significant time at a technology company. Experience at an AI company is preferred.
• A track record as one of the first or early security executives in a fast-moving, high-stakes environment, comfortable setting strategy while still working close to tooling, architecture, and incident command.
• Deep expertise in two or more of: detection engineering, incident response, digital forensics, infrastructure security, product or application security, operational security, or secure software development.
• Hands-on experience securing cloud-native, large-scale distributed systems, container and VM environments, and high-performance compute clusters.
• A record of building and shipping security tooling or research, whether internal platforms, open-source tools, or commercial products.
• Strong communication across functions. You can explain technical risk to non-technical leaders, work with research leads on new threat models, and review code and architecture.
• Genuine interest in AI safety, alignment, and the particular security problems of building AI models and AI agents.
• Preferred, though you are encouraged to apply even if you do not meet all of these: experience protecting model weights, secure multi-party computation, confidential computing, or supply-chain security at an AI lab or research organization.
• Preferred: published research, conference talks, or open-source contributions in security engineering or defensive operations.
• Preferred: experience at a startup or venture-backed company.
