Lead Security Detection Response Engineer

We’re solving some of the hardest problems in venture capital and private markets. You’ll work with a team that values precision, urgency, and long-term thinking. If you want to shape how startups are funded and built, this is the place.

We exist to accelerate innovation by increasing the number of successful startups in the world. We do this by building the financial infrastructure that makes it easier for more people to invest in world-changing companies.

AngelList is the nexus of venture capital and the startup community. We support $171B+ in assets and have powered investments into over 13,000 startups—over 300 of which are unicorns. Today, 57% of top-tier U.S. VC deals involve investors on AngelList. While our scale is large, our ambition is larger.

If you're excited to build the future of private markets, come build with us.

At AngelList, security is a creative function. You'll design systems that see what others miss. You'll write detection logic that actually means something. You'll build workflows that put the right alert in front of the right person at the right moment, not a firehose of noise that everyone learns to ignore.

This role has enormous scope. You'll work across product, infrastructure, and support. You'll decide what "good" looks like for how we respond to threats, both the obvious ones and the weird edge cases that keep you up at night. You'll be the person who notices the pattern before it becomes a problem.

We're looking for someone who sees AI as a lever, not a threat. Someone who's already thinking about how detection and response changes when you can automate judgment, not just rules. Someone who finds the current security playbook boring, because it is. You'll report to the Head of Security and operate as a strategic partner, not a ticket-taker. If you want to reinvent what this function can be, we want to talk.

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, New York City and San Francisco. We have a hybrid in-office model: teammates come in at least 2 days per week (Tuesdays and either Wednesday or Thursday). Exceptions may be made for exceptional individual contributor candidates in other locations.

Compensation: The compensation for this role consists of a competitive base salary, benefits, and equity package. The base salary for this role is $200,000+ annually but actual will vary based on a number of factors including a candidate’s professional background, experience, and location. Additional details about our Total Rewards package will be provided during the recruitment process.

We support your life both in and outside of work.

At AngelList, we are united in our purpose to accelerate innovation and build the future of private markets. Our beliefs and values shape what we work on and how we create impact. If the below resonate, we’d love to have you with us.
