About the role

As a Software Engineer on Ledger at Cardless, you'll own the system that tracks what every cardholder owes us and what we owe them.

The ledger is the system of record for balances across every card program we run. Statements, interest, how payments get applied, what a customer sees in the app, what we report to our partners: all of it depends on the ledger being right. You'll own its architecture.

Credit ledgers are harder than most. A balance revolves, accrues interest, gets billed on a cycle, and takes payments that have to be applied across principal, fees, and interest in a particular order. When any of that is wrong it turns up in someone's statement, or in a regulatory filing, or in a reconciliation break three weeks later. This is a senior-to-staff role with real architectural ownership, and it's a founding engineering role on our ledger and credit systems.

What you'll do

• Own the double-entry ledger that is the system of record for balances across every card program we run, and the invariants it has to hold
• Build the credit mechanics on top of it: billing cycle close, statement generation, interest accrual, payment allocation, fees, delinquency, and charge-off
• Own reconciliation from sub-ledger to GL, and build the break detection that catches silent failures before close
• Set the architecture and decide what gets built in what order
• Work directly with Finance, Compliance, and our partners on the requirements a ledger has to satisfy to survive an audit

What we're looking for

• 6+ years building production backend systems, with meaningful time on ledger, core banking, money movement, or payments platform work
• You've built one, not integrated with one. At least one of: a double-entry ledger that became the system of record for balances; in-house card processing or authorization and settlement infrastructure; or a migration of a card or money-movement program off a third-party processor onto in-house rails
• You think in invariants: idempotency, immutability, event sourcing, what has to hold at all times and how you'd prove it holds
• Strong distributed systems and API fundamentals in a modern backend language
• You're comfortable with ambiguity. You'll be scoping your own work, and you'll have to explain your tradeoffs to colleagues across functions

Bonus Points

• Credit card ledgers specifically: revolving credit, billing cycles, interest accrual, APR, minimum payments, payment waterfalls, installment plans, Reg Z / TILA
• Auth-to-settlement lifecycle: pending versus posted, capture, clearing, network files, ISO 8583, refunds and reversals, dispute and chargeback accounting
• You built or rewrote the ledger at a Chime, Stripe, Block, Affirm, Brex, Ramp, Mercury, Increase, or Modern Treasury and want to own one end to end
• You built an issuing platform at a Marqeta, Lithic, Highnote, Galileo and want to be on the program side of it

This role isn't a fit if

• You want a spec handed to you. Scoping the work is part of the job
• You reach for eventual consistency by default
• You want distance from Finance, Compliance, and operations
• You want to work remotely

Why this role

A ledger is one of the few systems where there's no partial credit. A balance is either right or it isn't, and everyone downstream finds out which. You'd own that across every program on the platform, which is a wider surface than most ledger roles come with.
