Software Engineer - Platform, Accounting

Full-time · Engineering · San Francisco, CA (3 days/week in office)

An engineer to build the multi-organization, multi-currency ledger that runs our books - working directly withaccounting, toward a close measured in minutes rather than days.

We are building the ledger that runs our books: multi-organization, multi-currency, and double-entry. It has tohold up across legal entities and regulators, across Bitcoin and fiat, and across the reporting requirements of aregulated life insurer. And we think it can be fast. Insurance closes have always been measured in days or weeks -reconciliation, chasing exceptions, waiting on entries. In the age of AI agents, we believe an insurance ledgercan close in minutes, and we're building toward that from a blank page rather than retrofitting it ontoforty-year-old systems.

This is a specialized, hands-on engineering role embedded with our accounting department. You'll sit withaccountants, learn how they actually close a period, and build the system that lets them do it. It's deep, precisework with real consequences: the ledger is what the financial statements are built on.

We're looking for someone who wants to go deep here as an individual contributor - the person who understands thefinancial core of the company better than anyone else and owns it.

What You'll Do

• Design and build our multi-organization, multi-currency general ledger - chart of accounts, journal entries,postings, period close, intercompany, FX and BTC revaluation, reconciliation
• Work directly with the accounting team to elicit and refine requirements - you own that relationship and thatdiscovery
• Get the hard modeling decisions right: idempotency, immutability and correction semantics, precision androunding, audit trails, effective dating
• Build the reconciliation and reporting surfaces that accounting, finance, and our auditors depend on
• Make the ledger legible to the rest of engineering, so other product verticals can post to it correctly
• Write production code across the stack (Python backend, React/TypeScript frontend, PostgreSQL)
• Use AI tooling to move faster, with the judgment to know when its output needs a second look
• Participate in business-hours on-call rotation shared across the engineering team (no nights/weekends)

How We Work

We don't have product managers. You'll work with the accounting team directly to understand the problem, shape thesolution, and explain the tradeoffs - that discovery is part of the job, not something that happens before itreaches you.

We lean into AI tooling and you'll have it. It's a real accelerant here, and we expect you to use it well. Butfinancial systems fail quietly - in ways that look correct until someone finds them at audit - so the work stillrests on thinking carefully about the problem, the data model, and the failure modes.

Qualifications

Required

• 5+ years of professional software engineering experience
• Direct experience building or operating accounting, ledger, or double-entry financial systems. Adjacentexperience counts where the accounting semantics were genuinely yours: core banking, payments and settlement,exchange or clearing back office, billing and revenue recognition at scale
• Strong backend engineering foundation, with the ability to ship the frontend surfaces your system needs
• Experience working directly with non-technical domain experts - accountants, controllers, auditors - and turningtheir problems into software
• Fluency with AI development tools, and the judgment to evaluate what they produce
• Comfort with ambiguity and a habit of teaching yourself the domain
• Low-ego approach and a high bar for precision
• Based in the SF Bay Area with the ability to work in-office 3 days per week

What Makes You Stand Out

• Multi-entity and multi-currency accounting experience - consolidation, intercompany elimination, FX revaluation
• Experience supporting a statutory audit or a regulated financial reporting cycle
• Insurance domain exposure (statutory vs. GAAP/IFRS reporting, reserving, premium and claims accounting)
• Interest in or experience with cryptocurrency, and the accounting questions Bitcoin raises
• Startup experience on small engineering teams (<10 people)
• A CPA, an accounting background, or a track record of being the engineer accountants trust

Technical Environment

• Backend: Python
• Frontend: React/TypeScript
• Database: PostgreSQL
• CI/CD: GitHub Actions
• Cloud: AWS

Why Join Us?

• A problem with a right answer: Financial correctness is unforgiving, and getting it right is genuinelysatisfying work
• Real Ownership: You'll own the ledger - the system everything else settles against
• Unique Domain: Build the accounting foundation for first-of-their-kind Bitcoin-denominated financialproducts
• Direct Influence: Small team, flat organization, direct access to leadership
• A seat with the business: You work with accounting every day, not through a translation layer
• Benefits:
  • Fully covered health, dental, and vision for you and your family
  • Meals provided in office
  • Two annual company off sites (fully paid)
