Staff Engineer

Founded in Silicon Valley in 2009 by Marc Andreessen and Ben Horowitz, Andreessen Horowitz (aka a16z) is a venture capital firm that backs bold entrepreneurs building the future through technology. We are stage agnostic. We invest in seed to venture to growth-stage technology companies, across AI, bio + healthcare, consumer, crypto, enterprise, fintech, games, and companies building toward American dynamism. a16z has $100B+ under management across multiple funds.

We’ve established a team that is defined by respect for the entrepreneur and the company-building process; we know what it’s like to be in the founder’s shoes. We’ve invested in companies like Anduril, Airbnb, Coinbase, Cursor, Databricks, Deel, Figma, GitHub, Roblox, SpaceX, and Stripe. Our team is at the forefront of new technology, helping founders and their companies impact and change the world.

The Role

We're hiring a Staff Engineer to own enterprise security at a16z: insider risk, data protection, SaaS security, and the secure adoption of AI across the firm. This is a program-ownership role. You'll set the strategy for how the firm protects its most sensitive data, pick and implement the tooling, write the policies with IT, and see them through to working controls.

The threats here are not theoretical. We handle material nonpublic information on deals and portfolio companies, and we see social engineering, data exfiltration risk, and threat actors who specifically target venture capital firms. At the same time, the firm is adopting AI tools and agents faster than almost any company of its size, and doing that safely is a core part of this job. Your work protects the firm, our LPs, and our portfolio companies. You'll work day to day with the Head of Cybersecurity, Security Engineering, IT, Legal, and Compliance.

This role requires an in-office presence 2 days a week, Tuesday and Thursday, in our San Francisco, CA office, with occasional days in our Menlo Park, CA office.
