Sr Staff Engineer - Rider Foundations

About the Role

The Rider Foundations team is responsible for the architecture, health, and quality of the Uber Rider app, serving hundreds of millions of users globally. We are in the midst of a generational technology transformation: adopting a new mobile architecture (Hyperion), building a GraphQL federation layer, launching a modernized Uber Lite experience, and reimagining how 200+ engineers build, test, and ship features. This Senior Staff IC will be a technical anchor across all of Rider Foundations : driving architecture decisions, raising the engineering bar, and shaping how the Rider app evolves over the next several years.

What the Candidate Will Do:

1. Serve as a technical anchor across Rider Foundations — contributing to architecture, health, and quality initiatives spanning backend services, mobile infrastructure, and developer tooling
2. Shape the technical strategy for Rider's next-generation app architecture, including GraphQL federation, new data layer patterns, and the migration path from legacy to modern systems
3. Drive engineering excellence across the broader Rider Core org (~70 engineers) — reviewing ERDs, raising the technical bar, and mentoring senior engineers
4. Partner with cross-org platform teams to align on API contracts, schema ownership, observability standards, and cross-platform technology strategy
5. Identify and tackle high-leverage technical problems that improve developer velocity, app reliability, and app quality — whether that means building new infrastructure, fixing systemic issues, or defining governance frameworks

What the Candidate Will Need:

1. 12+ years of software engineering experience with deep expertise in backend distributed systems and a strong understanding of mobile app ecosystems
2. Track record of driving large-scale, ambiguous technical initiatives across multiple teams — from strategy through production rollout
3. Experience designing APIs, data layers, or platform infrastructure that other engineering teams build on top of.
4. Experience with mobile app architecture patterns — understanding how backend services, APIs, and data layers integrate with iOS/Android clients at scale
5. Background in GraphQL, API federation, or API gateway design at high traffic volumes
6. Experience improving developer velocity at an organizational level — build systems, testing infrastructure, observability, or developer tooling
7. Demonstrated ability to influence technical direction beyond your own team, including reviewing designs, mentoring senior engineers, and setting architectural standards
