Senior Software Engineer (Full-Stack, Fintech) in Los Angeles

We replace paper checks with digital payments and connect law firms and medical providers into a real-time payment network - automating IOLTA trust disbursements, reconciliation, and compliance from end to end.

The problem is massive, painfully manual, and largely untouched by modern software.

If you've ever thought:

• "Why are people still printing and mailing checks in 2026?"
• "Why does reconciling money still involve spreadsheets and human error?"
• "Why isn't there a system that just... handles all of this automatically?"

That's exactly what we're building.

This isn't a CRUD app. This is high-stakes money movement, compliance-critical workflows, and multi-party financial coordination - all in one system.

We're dealing with:

• Real-time payments (ACH, RTP, wires)
• Trust accounting (IOLTA compliance)
• Multi-party disbursements (law firms, providers, clients)
• Reconciliation across bank, books, and ledger
• Audit trails that actually matter

The bar is high. The edge cases are real. The impact is immediate.

You're not just shipping features - you're replacing an entire manual system that law firms rely on today., We're hiring a Senior Software Engineer to help build the core infrastructure and product powering Disbo.
