> Build and own the core payments and financial ledger architecture for GovWell's AI-powered government services platform. Design auditable transactional systems handling fees, partial payments, refunds and migrations for municipalities, with high ownership shaping the domain from first principles.

## Job Description

## What you'll do
- Design the financial architecture GovWell runs on — the system of record for every dollar municipalities collect, refund, or hold on someone's behalf.
- Build a real ledger from the ground up: one that's fully auditable, mathematically consistent, and trusted by finance teams without a second look.
- Turn fee calculation into a system that computes with precision, instead of something staff track by hand or reconstruct after the fact.
- Make partial payments, deposits, and refunds first-class citizens of the platform, not workarounds bolted on after the core system was built.
- Own the migration from where payments live today to where they need to be — with real customers, real money, and no room for a clean-slate do-over.
- Partner directly with the people who depend on this system being right: finance teams, municipal staff, and the engineers building the workflows this ledger will support.
- Set the technical standard other engineers build against once this domain exists — you're not implementing someone else's design, you're establishing it.

## Who you are
- Experience designing financial or transactional systems where correctness isn't optional — payments, billing, ledgers, or similar domains where an unbalanced number is a real problem, not a bug ticket.
- You have real opinions about how a payments system should be architected, and you want a role where you can bring them, not just implement someone else's spec.
- Comfortable with ambiguity at the domain-design level: this isn't "build this feature," it's "help decide what the right abstraction is," and you find that exciting rather than uncomfortable.
- Experience with idempotency, webhooks, and payment processor integrations (Stripe, Finix, or similar) is a strong plus.
- You think in terms of invariants and edge cases — what happens when a webhook fires twice, when a fee schedule changes mid-invoice, when a refund needs to partially reverse a payment that's already been partially paid.
- You're excited to work with the latest AI models, both in the product and in your own development workflow.
- You've owned a large product area end-to-end and can point to something specific you shipped and stayed accountable for.
- Strong product instincts: you ask questions until you actually understand the customer's problem, not just the ticket description.
- You align closely with our Core Values.
