Lead Security Engineer

Private markets are the new public markets. The most important companies of this era are private, and almost no one can own them. What's missing is the financial system public markets spent a century building: exchanges, custodians, brokers, and ways for ordinary people to buy in. Private markets, now $28T, never had the equivalent. AngelList is building it.

The last decade of structural innovation in venture happened here: syndicates, SPVs at scale, Rolling Funds, scout programs. Today we have $200B+ in assets and 30,000+ startups funded on our platform. The rest of private markets is next. Funds is the software and services behind private funds, Nova is the banking network, Meridian is the wealth platform for accredited investors, and USVC is the brand behind a registered fund that lets anyone invest in venture.

Working here means an unusual amount of agency on a problem that matters. Titles are closer to suggestions, and there are about 200 of us building what private markets never had. Come build it with us.

7+ years across security engineering, cloud security, infrastructure security, or identity — including deep hands-on AWS/GCP security architecture and IAM.

Write real software. You build automation and internal tooling to solve security problems rather than relying on commercial products, and you know when buying is the better call.

Have driven security changes across engineering teams that didn't report to you, through influence and better tooling rather than mandates.

Fluent in infrastructure-as-code, CI/CD, and modern DevOps. You have shipped security controls into engineering platforms that developers actually adopted.

Reason about systems, not findings. You spot systemic weaknesses and fix the class of problem rather than the instance.

Built something with AI that changed how you work and have opinions about where human judgment still belongs.

If you don’t meet every requirement above, we still encourage you to apply. We value complementary strengths and operators who learn by doing.

AngelList has offices in a few cities, with our engineering hub in San Francisco. We’re building our engineering and product teams around this hub to make the most of in-person collaboration. We have a hybrid in-office model: teammates come in at least 2 days per week (Tuesdays and either Wednesday or Thursday).

Strong preference for SF; may consider NYC.
