Senior Software Engineer - Accounting & Ledger Systems

What You'll Do

• Design and extend our core ledger — accounts, postings, and the account-type/ledger structures that every financial product is built on.
• Own the chart-of-accounts and reporting surface that connects engineering data to financial statements and downstream reporting.
• Work across the boundary between on-chain data and off-chain books: balance verification, reconciliation, and proof-of-reserve style mechanisms.
• Partner with engineering teams early in the design process to make sure new features correctly model legal entity ownership, ledger placement, pricing, and reconciliation paths — before they ship, not after.
• Design data models that can absorb new financial products (margin, lending, staking, tokenized assets, and more) cleanly, without repeated painful migrations.

What We're Looking For

• Real, working knowledge of accounting fundamentals: double-entry bookkeeping, chart-of-accounts design, financial statements (P&L, balance sheet), and what reconciliation and audit actually require in practice.
• 5+ years of backend software engineering experience, with a track record of owning data-model design for systems where correctness is the product, not just uptime.
• Strong instincts for extensible system design — schemas and APIs that can grow with new requirements instead of requiring repeated rework.
• Comfort reading and critiquing technical designs across multiple systems, not just writing your own.
• Strong cross-functional communication — you'll work directly with Finance, Data Engineering, and Product on shared designs.

Nice to Have

• Experience in crypto or blockchain infrastructure — on-chain balance models, custody, or wallet architecture.
• Experience with event-driven or Kafka-based service architectures.
• Prior experience in an embedded "accounting architecture" or financial-systems design-review role at a fintech or crypto company.
