About Disbo

Disbo is building the financial operating system for the legal industry.

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.

The Role

We’re hiring a Senior Software Engineer to help build the core infrastructure and product powering Disbo.

This is a high-ownership, product-focused role — you’ll work directly with the founder and engineering leadership to design, build, and ship systems that handle real money movement and compliance.

You will:

• Own features end-to-end
• Make architectural decisions
• Work on complex, real-world financial workflows

What You’ll Do

• Design, build, and ship full-stack features (React + Rails)
• Architect systems for payments, disbursement logic, and reconciliation
• Integrate with payment infrastructure (Modern Treasury, ACH, wires, RTP)
• Build scalable, reliable backend services and APIs
• Handle complex edge cases around money movement and compliance
• Improve system performance, observability, and reliability
• Debug production issues and move fast to resolution
• Collaborate closely with product, ops, and leadership

Tech Stack

• Frontend: React, Redux, Tailwind
• Backend: Ruby on Rails
• Database: PostgreSQL
• Infra: Heroku (evolving), cloud-native direction
• Integrations: Modern Treasury, Filevine (Clio & QuickBooks next)

What We’re Looking For

• 3+ years of experience building production systems
• Strong full-stack experience (frontend + backend)
• Experience designing scalable systems and APIs
• Comfortable owning problems end-to-end (not just tickets)
• Strong debugging and problem-solving skills
• Ability to operate in a fast-paced, ambiguous startup environment

Nice to Have (Strong Plus)

• Fintech / payments / money movement experience
• Experience with ledgers, reconciliation, or accounting systems
• Experience integrating third-party APIs
• Experience with QuickBooks, Clio, or legal/financial systems
• Startup or 0→1 experience

Why This Role is Different

• You’re working on real money movement , not internal tools
• The system you build directly impacts law firms, doctors, and clients getting paid
• You’ll face non-trivial engineering problems (not just UI features)
• You’ll have real ownership over architecture and product decisions
• You’ll work directly with leadership — no layers, no bureaucracy
