Senior Staff Software Engineer, Fintech Invoicing & Payments

On the Fintech Invoicing & Payments team, we build the AI-native sales transaction experience for QuickBooks Online - the Platform where small businesses get paid. As a Senior Staff Software Engineer on the team, you will drive significant, end-to-end technology initiatives across both horizontal layers - from the React form a merchant sees to the MCP tool an agent calls to the GraphQL/STS write that lands in QuickBooks - executing with a boundaryless mindset and contributing well outside any single repo’s ownership. The hard, domain-specific work here is making an LLM reliably and safely operate a real accounting system: writing tool descriptions and structured-content contracts precise enough that the model stops asking redundant clarifying questions yet never corrupts a ledger.

You’ll partner across a highly matrixed set of stakeholders (Omni, the QBO monolith, payments, design, and external MCP-host partners) to translate customer behavior into durable, scalable, secure designs that balance short-term delivery against long-term architecture. Critically, you’ll guide where AI genuinely helps and where it doesn’t: you bring a deep, hands-on understanding of LLMs and prompt/tool-description engineering, agent orchestration (LangChain/LangGraph-style frameworks), and the evaluation tooling needed to validate accuracy and prevent regressions before they reach a customer’s books.
