Senior Software Engineer - Ledger
Roblox · San Mateo, CA, United States
About this role
**About Roblox** Every day, tens of millions of people come to Roblox to explore, create, play, learn, and connect with friends in 3D immersive digital experiences—all created by our global community of developers and creators. At Roblox, we’re building the tools and platform that empower our community to bring any experience they can imagine to life. Our vision is to reimagine the way people come together, from anywhere in the world, and on any device. A career at Roblox means you’ll be working to shape the future of human interaction, solving unique technical challenges at scale, and helping to create safer, more civil shared experiences for everyone. --- **What You’ll Do** 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. You’ll help ensure the Ledger is the trusted foundation for users, creators, and the economy by serving as the source of truth in both directions: every write of value, and every read of it (balances, history, statements, reconciliation, and analytics). Robux already runs entirely on our zero-balanced, double-entry ledger, and Creator Wallets launch in December 2026. As a Senior Software Engineer, you’ll design, build, and scale the systems that make this true—where correctness is the product. --- **You Have** - 4+ years of backend software engineering experience designing, building, and maintaining robust and scalable systems (e.g., microservices, APIs) - Strong problem-solving skills and experience debugging complex issues in distributed systems - Experience managing projects, planning, and executing work across different workstreams - Strong collaboration skills; ability to work across teams and organizations; mentoring and guiding junior engineers - Bachelor’s degree in Computer Science, Computer Engineering, or a similar technical field - Financial infrastructure / ledgers / accounting experience (highly desirable). Experience building a ledger or double-entry system is a strong plus - Experience with large-scale data or analytical systems (OLAP, event-driven pipelines, or similar) is a plus --- **You Will** - 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 --- **Pay Transparency (HQ: San Mateo, CA)** - Annual Salary Range: **$196,750 – $243,290 USD** - Actual base pay depends on factors such as background, training, experience, location, business needs, and market demand - Equity compensation and benefits are also available --- **Work Location / Schedule** Roles based in an office are onsite **Tuesday, Wednesday, and Thursday**, with opt
