About The Position

Join Roblox’s Ledger team to build and scale the system of record for its global economy. The Ledger is intended to track all movement of value—including virtual currency, fiat, and digital assets—accurately, in balance, and with full auditability. It serves as the authoritative source for both recording value and answering questions about it, including balances, history, statements, reconciliation, and analytics. Robux already runs on the zero-balanced, double-entry ledger, and Creator Wallets are planned to launch in December 2026. The role designs, builds, and operates systems where correctness is essential. The Senior Software Engineer will work with Finance, product, and economy engineering teams to ensure value movements are correct at the source. The position owns both ledger write paths and read paths, and contributes to idempotent, exactly-once processing, reconciliation, precision guarantees, operational reliability, and engineering quality. For roles based at Roblox’s headquarters in San Mateo, California, the annual base salary range is $196,750–$243,290. Actual pay may vary based on job-related factors. The range may change. Full-time employees are eligible for equity compensation and benefits. Office-based roles are onsite Tuesday, Wednesday, and Thursday, with optional presence Monday and Friday unless otherwise noted.
