We build the workflows and automations that turn complex financial operations into reliable, traceable and efficient processes for finance teams.

You will work closely with Product, Design, Accounting specialists and other Engineering teams to solve complex domain problems and deliver robust systems. You will be expected to contribute beyond implementation by shaping architecture, clarifying technical trade-offs, raising engineering standards and helping the squad make sound long-term decisions.

• Build clear accounting visibility and auditability for Finance teams.

Why join Accounting?

• Work on a critical product area where correctness, reliability and traceability directly matter to customers.

• Solve complex problems at the intersection of software engineering, finance and accounting.

• Build systems that support the full journey from company spend to accurate bookkeeping and financial close.

• Work on automation, reconciliation and financial data quality at scale.

• Have a direct impact on how Finance teams save time, reduce manual work and trust their financial data.
