## About the Role

* Experience: 8+ years of professional software engineering experience, with a strong track record in backend development and distributed systems.
 * Architecture: Proven ability to design large-scale, fault-tolerant systems from scratch. You understand the trade-offs between consistency and availability and know when "eventual consistency" is not enough.
 * High Agency: You thrive in ambiguity. You don't wait for a ticket to be assigned; you identify the business problem, scope the technical solution, and execute.
 * Domain Agility: You have the intellectual curiosity to master the complex domain of treasury and money movement in a matter of days, even if you don't have a background in it.
 * Tech Stack: Deep proficiency in a modern backend language (Python, Go, Java, etc.) plus experience with complex data modeling (SQL/NoSQL) and data processing framework (Spark/Flink).

## Description

Rippling processes multi-billions of dollars in annual transaction volume, serving as the financial engine for businesses worldwide. As a Staff Engineer on the broader Financial Services team, you will join a lean, high-impact group responsible for the architecture that moves this money., We're looking for a Staff Software Engineer to anchor our new Money Movement & Treasury architecture hub in Seattle. You will own the design and implementation of our deterministic, config-driven, and incrementally testable ledger architecture. You will be the technical authority ensuring 100% ledger coverage to act as the final guardrail for all tax and payment liabilities., * Architect the Foundation: Redesign our General Ledger and reconciliation systems to eliminate silent failures and to be deterministic.

 * Unify the Abstraction: Establish universal primitives across various historically disjointed payment systems to create a single, queryable lifecycle for every dollar moving through our platform.
 * Build the Engine: Develop a reconciliation replay and testing framework, working closely with the payments data team to replace legacy Snowflake-side recon logic.
 * Technical Leadership: Anchor the Seattle site, mentoring a pod of high-performing Senior engineers to build an execution layer decoupled from product feature velocity.
 * Cross Functional Execution: The engineer will work closely and collaborate with the Payments Data, Tax, and Accounting team to understand ledger, tax liability, accounting and regulatory reporting requirements, and to replace legacy Snowflake-side reconciliation logic by developing a reconciliation replay and testing framework.
