Software Engineer II

Commercial Technology builds the systems behind how customers buy, finance, and take delivery of their Rivian. Our team owns the backend services that calculate taxes and fees, manage title and registration, power finance and lease pricing, and connect Rivian with external partners like DMV service providers, lenders, and our ERP. Our work directly affects every vehicle delivery, including the launch of R2.

We're looking for a Software Engineer II to join our backend team and help build and scale the services that make sure every customer is charged correctly and every vehicle is titled and registered correctly. You'll work across state-specific tax and fee rules, third-party integrations, and order management workflows, and partner closely with Title & Registration Operations, Tax, Finance, and Program Management. This role fits someone who enjoys going deep in a complex domain, values accuracy, and wants to build systems that scale as we expand to new states, dealers, and vehicle programs.

Integrate with third-party partners (e.g., tax/registration vendors, SAP) and help drive issues to resolution with external teams

Implement and maintain state- and jurisdiction-specific rules, and help move them toward configurable, maintainable systems

Support new dealer and location launches, vehicle programs (e.g., R2), and state expansions

Work with Order Management, Finance, and Shop engineering teams to deliver end-to-end features

Take part in on-call rotations, triage production issues, and support operational partners

Write clean, well-tested code and contribute to code reviews, documentation, and team best practices

Familiarity with relational databases and event-driven or messaging systems (e.g., Kafka)
