Senior React Developer Jobs

About the team: Rubrik's mission is to secure and accelerate the world's AI transformation. IT is where we apply that to ourselves. We're moving Rubrik's own enterprise off a traditional application stack and onto an intelligent one. Our goal is what we call the Thinking Enterprise: applications that run the business instead of just recording it. They learn from our data, act through our agents, and improve with each decision. That work is already underway, and we'd like you to help build it. We build the internal products our Accounting, Controllership, and Tax teams use every day, the tools that decide how fast we close the books and how much we can trust the numbers. About the role: In our approach to accounting, agents understand the chart of accounts, the accounting policy, and the transaction in front of them, and they carry an entry from the source event through to a posted, audit-ready record. If you're curious about why every task on the close calendar sits where it does, and whether most of those tasks can be run by agents as the work happens, so that only the final close needs to be locked down and compliant; if you know which steps can be questioned and rebuilt and which must follow the rules every time; and if you're excited about shortening the close by removing manual effort, then you're in the right place. What you'll do: Lead product strategy for accounting (general ledger, close, intercompany, reconciliations, fixed assets, Sub-ledger accounting, and commissions), rebuilding rather than patching. Bring an AI-first approach, introducing agents, evals, and automation into real accounting workflows with audit-level stakes. Design how agents are built and tested: break complex accounting work into well-scoped steps, define evals, and set clear human-in-the-loop checkpoints for approvals and audit-sensitive decisions. Apply first-principles thinking, taking a legacy close task, asking why it exists, and building what replaces it. Own the vision and road
