About AngelList

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.

About the role:

The strongest security programs are built by designing systems where the secure path is the easiest path. We're hiring someone to build those systems.

You'll be a hands-on engineer who designs and builds the systems that make security a property of our infrastructure: a unified identity and access layer, cloud security, automated provisioning and revocation, and the guardrails that let teams ship fast. You will work directly with Infrastructure, Engineering, IT, and Product to roll them out.

We want someone who sees AI as a way to change how security engineering operates. Instead of triaging alerts faster, this person will work toward systems that understand context, make decisions, and remediate autonomously. You’ll report to the Head of Security, on a small team with a large scope.
