Rippling gives businesses one place to run HR, IT, and Finance. It brings together all of the workforce systems that are normally scattered across a company, like payroll, expenses, benefits, and computers. For the first time ever, you can manage and automate every part of the employee lifecycle in a single system. Take onboarding, for example. With Rippling, you can hire a new employee anywhere in the world and set up their payroll, corporate card, computer, benefits, and even third-party apps like Slack and Microsoft 365—all within 90 seconds.

Based in San Francisco, CA, Rippling has raised $1.4B+ from the world’s top investors—including Kleiner Perkins, Founders Fund, Sequoia, Greenoaks, and Bedrock—and was named one of America's best startup employers by Forbes.

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.

• 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…
