Partner 20, Staff Engineer, Incident Response
a16zSan Francisco, California, United States · Posted 2 months agoDescription
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 Incident Response Engineer to anchor a16z's detection and response work. You'll own incident triage and response across AWS and GCP, write the detections that catch real threats in our SIEM, and run point when something serious happens.
The threats here are not theoretical. We see capital call wire fraud attempts, vishing campaigns, social engineering against IT and partners, and occasionally more sophisticated actors (nation-state groups, organized criminal operations) who specifically target venture capital firms. 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, and Legal.
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:
- Run incidents end to end, from first alert to post-mortem, across cloud and SaaS environments
- Write the detections that catch real threats, with a strong bias toward signal over noise and broad MITRE ATT&CK coverage
- Help shape the next generation of our SOC, including AI agent integration into triage and response workflows
- Partner across the firm during incidents: investing teams, Legal, Compliance, Finance, IT, and firm leadership all get pulled in, and this role keeps every audience aligned under pressure
- Drive post-mortems that lead to operational change, not process for its own sake
- Work against real adversaries, including nation-state groups, organized criminal operations, and threat actors who specifically target venture capital firms
Minimum Qualifications
- 5+ years of incident response experience or equivalent demonstrated impact, with cloud IR depth across both AWS and GCP
- Experience leading live incidents end to end — triage, containment, eradication, forensic investigation, and post-mortem — across cloud, SaaS, identity, and endpoint surfaces
- Experience running proactive, hypothesis-driven threat hunts using current TTPs and intel
- Hands-on detection authoring in modern SIEM platforms (Sigma, KQL, or equivalent) and experience working with detection-as-code
- Experience building detection frameworks and contributing to SIEM architecture decisions
- Strong Python scripting. This is a role where you build automation, not one where you only operate someone else's
- Demonstrated capability across modern security tooling categories (cloud telemetry, EDR, SOAR, SIEM). We weight transferable capability over experience with any specific product
- GCIH or equivalent IR certification preferred
- Comfortable in a fast-moving environment where security is expected to enable the business
- Experience defending against nation-state threat actors or organized criminal groups
- Working knowledge of AI/agent systems and their security implications, particularly in SOC workflows
- Experience translating the technical reality of an incident (blast radius, containment status, disclosure decisions) into language non-technical stakeholders can act on.
- Low ego, high empathy, and the capacity to collaborate effectively with diverse teams
The anticipated salary range for this role is between $243,000 - $284,000, actual starting pay may vary based on a range of factors which can include experience, skills, and scope.
This role is eligible to participate in the a16z carry program and various discretionary bonus programs as well as benefit and perquisite plans including health, dental, vision, disability, life insurance, 401K plan, vacation, and sick leave.
