We’ve invested in <a href="https://a16z.com/portfolio/">companies</a> like Anduril, Airbnb, Coinbase, Cursor, Databricks, Deel, Figma, GitHub, Roblox, SpaceX, and Stripe.

Your mandate is leverage — connect the tools the security team relies on, centralize the data they generate, and build the dashboards and AI-native automations that let a small team (Security Engineering and Incident Response) operate at the scale of a much larger one.</span></p> <p><span style="font-family: 'times new roman', times, serif;">This is an AI-native role. You'll build with and on AI: LLM-augmented workflows, agentic automations, AI-assisted analysis as a first-class building block — and you'll help the rest of the security team get more leverage out of AI in their own work.</span></p> <p><span style="font-family: 'times new roman', times, serif;">a16z's security stack spans cloud telemetry, SIEM, identity, endpoint, vulnerability scanning, ticketing, and more. The team needs them stitched into one picture and one workflow rather than ten siloed ones. You'll be the person who makes that real. You'll work day to day with the Security Engineering Lead, Incident Response, SecOps, IT, and ASG(A16Z’s Applied Software Group).</span></p> <p><span style="font-family: 'times new roman', times, serif;">Venture capital firms face targeted, sophisticated threats — capital call wire fraud, vishing, social engineering, and threat actors who specifically pursue firms in this space. Your work protects the firm, our LPs, and our portfolio companies.</span></p> <p><span style="font-family: 'times new roman', times, serif;">This role requires an in-office presence 2 days a week in our San Francisco, CA office.</span></p> <h2><span style="font-family: 'times new roman', times, serif;">To join our team, you should be excited to: </span></h2> <ul> <li style="font-family: 'times new roman', times, serif;"><span style="font-family: 'times new roman', times, serif;">Build the connective tissue across the security tools the org relies on — SIEM, vulnerability scanners, EDR, identity, asset management, ticketing — and centralize the data they generate into a single picture the team can act on</span></li> <li style="font-family: 'times new roman', times, serif;"><span style="font-family: 'times new roman', times, serif;">Use AI as a first-class building block - LLM-augmented analysis, agentic automations, AI-assisted summarization - and design for compounding leverage, not one-off scripts</span></li> <li style="font-family: 'times new roman', times, serif;"><span style="font-family: 'times new roman', times, serif;">Build the frameworks and dashboards that unify asset inventory, vulnerability posture, exposure reviews, and compliance evidence across systems</span></li> <li style="font-family: 'times new roman', times, serif;"><span style="font-family: 'times new roman', times, serif;">Take the bigger automation problems off the team's plate — vulnerability management at scale, asset hygiene, access reviews, and the workflows that span multiple tools</span></li> <li style="font-family: 'times new roman', times, serif;"><span style="font-family: 'times new roman', times, serif;">Raise the rest of the security team's leverage with AI - share patterns, ship tooling others use, and make it easy for security engineers and IR engineers to add AI to their own…
