▸about a16z — company background

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’ve invested in companies like Anduril, Airbnb, Coinbase, Cursor, Databricks, Deel, Figma, GitHub, Roblox, SpaceX, and Stripe.

The Role

We're hiring a Lead Engineer, Incident Response to lead and shape a16z's detection and response team. This is a hands-on role: you'll spend a significant portion of your time investigating incidents, writing and reviewing detections, building automation, and making the harder technical response decisions. You'll also manage and develop the engineers on the team.

You'll build and improve detection and response capabilities across the firm's cloud, SaaS, identity, and endpoint environments, shaping the roadmap, tooling, threat hunting, and response practices. You'll also develop capabilities to protect the firm against impersonation and fraud. You'll work closely with Security Engineering, IT, Legal, Compliance, and other cross-functional teams to put these capabilities into practice and turn lessons from incidents into better detections, tooling, and controls.

Venture capital firms face threats that extend beyond their infrastructure: capital call wire fraud, impersonation, and social engineering against employees and partners, alongside attacks by organized criminal and nation-state groups. Your work protects sensitive firm and limited partner (LP) information, financial transactions, and the relationships the firm depends on.

This role requires an in-office presence 2 days a week in our San Francisco, CA office.

To join our team, you should be excited to:

Set the detection and response roadmap, prioritizing the threats that matter most to the firm and measuring detection coverage, alert quality, and response effectiveness
