- Model money movement with double-entry accounting, including returns, reversals, fees, and FX
- Build reconciliation between the ledger, bank statements, and on-chain wallet balances

- Write thorough tests
- Review teammates' code
- Work closely with finance, compliance, and payment operations teams
Requirements:
- 5+ years of professional back-end development experience

- Solid understanding of double-entry accounting: debits, credits, balances and reconciliation
- Strong experience with Kotlin or Java; the company uses Kotlin
- Experience with relational databases such as Postgres
- Experience with exact decimal arithmetic, idempotency, and consistency in distributed systems
- Experience with message-driven architectures, e.g. RabbitMQ
- Hands-on experience with AI-assisted development and judgment to review and question generated output
- Comfort with high autonomy and ambiguity in a fast-moving, remote startup
- Clear written communication; most collaboration is async
- Professional English required
- Candidates must be authorized to work in their country of residence
- Visa sponsorship is not available
- Background check may include criminal history, employment and education verification, and sanctions screening
- Nice-to-have: experience at a payments company, bank, or fintech, ideally with treasury or settlement

- Nice-to-have: experience with stablecoins, custody wallets, or on-chain reconciliation
- Nice-to-have: experience with FX, multi-currency accounting, or liquidity management
- Nice-to-have: experience with yield-bearing or financing instruments
- Nice-to-have: experience supporting audits or regulatory reporting
