## Description

We are looking for a Staff Software Engineer to join the Commerce Platform team at Ro. In this role, you will operate as a technical leader, mentor, and architect - helping shape the future of our platform and driving the delivery of financial systems that power how healthcare is accessed and sustained.

You will partner closely with other engineers, product managers, designers, and cross-functional leads to define and deliver technical roadmaps that balance immediate product needs with long-term technical stability, scalability, and maintainability. As a Staff Engineer, you will not only design and build robust distributed systems but also mentor engineers, influence engineering culture, and play a key role in technical decision-making.

 * Define and maintain SLIs/SLOs in collaboration with product, infra and other development teams
 * Participate in on-call rotations to ensure reliability of commerce systems
