Job summary

Seed Labs in San Francisco is seeking a Software Engineer to build the platform powering billions in private market volume. You will own features end-to-end across the stack, from investor onboarding to deal execution and compliance systems.

You’ll ship ambitious, revenue-impacting solutions on a small, high-ownership team. If you thrive on ambiguous problems and care deeply about correctness in money-moving systems, we’d love to talk.

Qualifications

• 3+ years building and shipping production web applications end-to-end.
• Strong with TypeScript and a modern React framework, plus backend & data layer.
• Care deeply about correctness in a money-moving system.
• Able to scope loosely-defined problems and ship without a fixed spec.
• Clear communicator who works with non-engineers to surface the real problem.

Responsibilities

• Ship full-stack features across the platform—from onboarding to operations tooling.
• Design and build systems that execute deals, track capital, and generate investor/tax reporting.
• Work with on-chain infrastructure to keep the ledger accurate and verifiable.
• Partner with operations, compliance, and finance to automate workflows.
• Own reliability: instrument, monitor, and fix issues before customers are affected.
