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:

AngelList's software automates the work for our in-house team of operators, accountants, and tax professionals to power the best-performing venture funds. $21.8 billion in capital is managed by our platform — and every dollar runs through the Accounting team’s infrastructure.

AngelList records every fund event (capital calls, wires, investments, conversions, distributions) in a ledger in real-time. The Accounting engineering team is the engine that ensures our entire platform is delivering clean, accurate and reliable financial statements automatically.

Our aim to win every top-tier customer is possible if we deliver financials more accurately and more quickly than anyone else. We're moving at lightning speed. We need to make our customers’ requests either self-serve, or so operationally tight, that it feels self-serve. We will get there by scaling our accounting system to automate more operational work. If you're detail-oriented, excited by data, and enjoy seeing the impact of what you build quickly, you'll love this team.

You will have the opportunity to:

• Model financial workflows—turning messy, real-world fund data into accurate and automated financials.
• Build scalable accounting infrastructure—improving how financial data is reported on the front-end, and building out how we read/write to the general ledger on the back-end.
• Solve hard data integrity problems—ensuring our system produces reliable and audit-ready outputs across a growing universe of more complex funds.
• Collaborate directly with accounting stakeholders in a tight feedback loop, turning their manual processes into automated, AI-native systems.
• Work with other highly talented and self-motivated colleagues driven by the same mission.

You most likely (are):

• Senior back-end engineer with deep systems design experience, architecting, deploying, and scaling complex, data-heavy web applications.
• 5+ years of experience (proficient in Rails or similar MVC architecture), owning features end to end and comfortable venturing into the frontend (React, TypeScript).
• Thrive on ambiguity—modeling ambiguous problems, messy data, and evolving business requirements in a relational database (Postgres, MySQL) where every record is critical.
• Build reliable software that eliminates operational friction—such as designing event-driven systems to produce automated, audit-ready financial outputs, not best-effort calculations.
• Customer-oriented to solve real business problems in collaboration with accounting professionals. 
• Thrive with financial complexity, including dealing with complex transactional systems, ledger logic, or working in other highly regulated industries. You are excited about the details of how money flows through the venture ecosystem.
