Senior Software Engineer - Ledger at Roblox · LumiJobs

Responsibilities

Join the Roblox Ledger team and build the system of record for a global economy. Our north star is that all movement of value on Roblox is tracked on the Ledger, and that every unit of value — virtual currency, fiat, or digital asset — is accurately tracked, perfectly balanced, and fully auditable. That makes the Ledger the trusted foundation for our users, creators, and economy.
We are the source of truth for the economy in both directions: every write of value, and every read of it. The same authoritative record that settles a transaction also has to answer the questions people ask about it — balances, history, statements, reconciliation, and analytics — so that read paths do not drift from the book of record. Robux already runs entirely on our zero-balanced, double-entry ledger, and Creator Wallets launch in December 2026. As a Senior Software Engineer, you will design, build, and scale the systems that make this true, in a domain where correctness is the product rather than a feature.
Work closely with Finance, product, and other economy engineering teams to make every movement of value correct at the source.
Architect, design, implement, and operate the ledger services that record every movement of value on Roblox.
Proactively identify and address correctness, performance, auditability, and operational risks in systems where a single bad entry is a financial incident.
Design idempotent, exactly-once write paths, plus the reconciliation that proves the books balance and the precision guarantees other teams build on.
Own both sides of the ledger: the write path that records value, and the read path that serves balances, history, and analytics from the same source of truth.
Uphold high standards for code quality, test coverage, and maintainability, fostering the culture of engineering excellence.
