This role will require being full-time onsite at our Toronto office to support collaborative team dynamics and innovative problem-solving. Bit Go is looking for a Senior Software Engineer to help build and evolve the ledger systems behind our clients balances, trading positions, and financial reporting.

You ll work at the intersection of software engineering and accounting — designing the double-entry ledger primitives that other engineering teams build on, and making sure new products are designed with financial correctness in mind from day one rather than retrofitted after launch.

This is a rare role for someone who genuinely understands accounting fundamentals and wants to apply that knowledge to hard distributed-systems problems in a live financial platform.

• 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.

• 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.

• 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.
