Description
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 that they can imagine to life. Our vision is to reimagine the way people come together, from anywhere in the world, and on any device. We’re on a mission to connect a billion people with optimism and civility, and looking for amazing talent to help us get there.
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. 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.
You Have:
- 4+ years of backend software engineering experience, demonstrating proficiency in 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 in 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.
- Experience in financial infrastructure, ledgers, accounting, or another domain where accuracy is non-negotiable is highly desirable. Experience building a ledger or double-entry system at another company is a strong plus.
- Experience with large-scale data or analytical systems (OLAP, event-driven pipelines, or similar) is a plus but not a requirement.
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, fostering the culture of engineering excellence.

About this role
Roblox's Ledger team owns the financial backbone of a platform serving tens of millions of users daily. As a Senior Software Engineer in this role, you'd be responsible for designing and operating the systems that track every movement of value—virtual currency, fiat, and digital assets—across the platform. The work demands absolute correctness: the ledger is the authoritative record for both writes (transactions) and reads (balances, history, reconciliation), and a single error constitutes a financial incident. You'd architect double-entry ledger systems, design idempotent write paths with exactly-once guarantees, and ensure the read paths serving analytics and user statements never drift from the source of truth.
This position suits someone with at least four years of backend engineering experience building distributed systems at scale, combined with strong debugging and project management skills. Experience in financial infrastructure, accounting systems, or previous ledger work is highly desirable—this is a domain where accuracy is the product, not a feature. You'd collaborate closely with Finance, product, and other economy teams, mentor junior engineers, and maintain rigorous standards for code quality and auditability. The role is based in San Mateo with in-office presence Tuesday through Thursday, and offers a salary range of $196,750–$243,290 plus equity and benefits.
