Level: Senior. The title says "Senior".

Must have

• 4+ years of backend software engineering experience, demonstrating proficiency in designing, building, and maintaining robust and scalable systems (e.g., microservices, APIs).
• Bachelor's degree in Computer Science, Computer Engineering, or a similar technical field.

Main duties

• 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.
