## Job description

## 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.

Responsibilities:

- Own AngelList’s security foundations across AWS infrastructure, identity, access control, authentication, authorization, and secrets management.
- Design and build security architecture and guardrails into infrastructure-as-code, CI/CD, and developer workflows so secure defaults are automatic.
- Build IAM systems and least-privilege access models that scale across employees, services, and machine identities — including access reviews and privileged access.
- Write security tooling and automation that finds weaknesses and remediates them without human intervention, harnessing AI where it raises decision quality.
- Solve security risks at the platform and architectural level, and contribute to application security through threat modeling, secure design, and vulnerability remediation.

You may be a good fit if you have:

- 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.

Working Here 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. Compensation:The compensation for this role consists of a competitive base salary, benefits, and equity package. The base salary for this role is $240,000+ 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. Benefits:We support your life both in and outside of work.

## About AngelList

## Company Overview
- **One-liner**: AngelList builds the financial system for private markets, providing the infrastructure where capital, creativity, and hard work come together to accelerate the rate of innovation.
- **Entity Type**: Private (venture-backed; $124.1M total funding across 8 rounds)
- **Headquarters**: San Francisco, California, United States (additional office in San Diego; workforce distributed across 31 countries)
- **Founded**: 2010
- **Founders**: Naval Ravikant and Babak Nivi

## Core Business
- **Primary industry**: Private market investment infrastructure / fintech (venture capital administration, fund management, startup investing)
- **Target customers**: B2B and B2C — fund managers, venture investors, syndicate leads, startups, and accredited/retail investors seeking access to private markets
- **Mission or purpose statement**: "The financial system for private markets." The company's stated goal is to solve the "ownership gap" for private companies — building the equivalent of public-market infrastructure (exchanges, custodians, transfer agents, brokers, retail distribution) for private markets, which now represent more than $28T in U.S. fund AUM.

## Products & Services
- **AngelList Funds**: The administration layer for venture capital — enables fund managers to launch and operate venture funds, SPVs, and syndicates on the platform.
- **USVC**: The brand behind retail access to venture investing, allowing non-institutional investors to participate in private-market deals.
- **Meridian**: The wealth layer for private markets; a platform for managing private-market assets and portfolio operations.
- **Nova** (coming soon): The banking and payments layer for private markets, announced as the next major product release.
- **Scout Funds & SPVs**: Additional investment vehicles supported on the platform alongside venture funds.

## Market Standing
- **Valuation/Market Cap**: Not disclosed (private company)
- **Key Metric**: Total funding of $124.1M (8 prior rounds). Platform scale figures are conflicting across sources: LinkedIn reports **$171B in assets on platform, 25K+ funds and syndicates, and 72K active investors**, while Built In reports **$15B in assets for fund managers, 17K+ startup investments (including 287 unicorns), and 1.3K startups using founder services** — both cited below as conflicting reports.
- **Notable Investors/Partners**: Not publicly available in the provided data sources.
- **Growth Signals**: Acquired Nova (banking/payments layer) in July 2023; acquired Prospectify (2019) and Product Hunt (2016, for $20M); has delivered $10B in capital to startups with a stated ambition to reach $10T; active hiring across Engineering, Data, Finance, Marketing, Legal, and Customer Success teams.

## Competitive Advantages
- **Network effects / de facto standard**: Positions itself as the default platform for startup investing, with 25K+ funds and syndicates and 72K active investors on platform (per LinkedIn data).
- **Full-stack private-market infrastructure**: Unlike point solutions, AngelList spans fund administration (Funds), retail access (USVC), wealth management (Meridian), and soon banking/payments (Nova) — a vertically integrated stack for private markets.
- **Data moat**: Years of transaction, fund, and investor data create switching costs for fund managers and investors alike.
- **Founder-friendly brand equity**: Long-standing reputation in the startup ecosystem, including backing 287 unicorns (per Built In).

## Strategic Focus
- **Launching Nova**: The banking and payments layer for private markets is positioned as the next major growth vector, completing the company's "financial system for private markets" vision.
- **Scaling Meridian**: Building out the wealth layer to serve private-market asset management at scale.
- **Expanding retail access**: Growing USVC to bring venture investing to a broader audience beyond accredited investors.
- **Growing platform AUM**: Pushing from $10B in capital delivered toward the stated $10T ambition.

## Why Work Here
- **Culture**: The company emphasizes high agency and ownership — described as "no ladders, only roads," where employees are expected to pave their own career paths and take on more than peers in the industry, faster, with less.
- **Work mode**: Hybrid roles available in San Francisco, CA and New York City, NY (e.g., Senior Platform Engineer, Investor Services Specialist, Investment Operations Associate).
- **Funder & founders program**: Employees can invest up to $100K from an AngelList fund into deals they source and earn 20% of the profits from those investments.
- **Financial wellbeing**: Competitive salary, 401K, equity, FSA, and access to a finance coach.
- **Healthcare**: Premium medical, dental, vision coverage, One Medical, wellness coach, FSA, Carrot fertility benefits, and generous parental leave.
- **Lifestyle perks**: Unlimited PTO, unlimited book stipend, wellness reimbursement, and a remote office budget (co-working/home office).
- **Office perks**: In-office meals, coffee walks, team offsites, commuter benefits, and safe rides home.
- **Team size (conflicting reports)**: The careers page cites a team of 140; LinkedIn reports 321 employees (-0.7% YoY); Built In reports 518 total employees across 3 offices.
