Software Dev Eng II - Mobile Observability, Builderworks

Are you passionate about building the systems that help engineers understand what's really happening inside mobile apps used by hundreds of millions of customers? Our team is building the next generation of mobile observability at Amazon — starting with the Amazon Shopping app and extending across Amazon's mobile portfolio. You'll work at the intersection of mobile engineering and distributed systems, designing and building crash reporting, performance monitoring, tracing, and telemetry infrastructure that gives app builders deep, real-time visibility into the health and behavior of their systems.

Key job responsibilities

• Design, build, and maintain mobile observability SDKs and services for both Android and iOS platforms, serving hundreds of engineering teams
• Drive the integration and extension of observability platforms, including evaluation, proof-of-concept, and production rollout
• Build and evolve telemetry pipelines for crash reporting, performance monitoring, distributed tracing, and real-time alerting at Amazon scale
• Create modular, extensible observability components for adoption across Amazon's mobile app portfolio
• Collaborate with cross-functional teams to define observability standards, metrics, and SLAs

A day in the life
You'll spend your time designing and building observability infrastructure that powers one of the most-downloaded shopping apps in the world. On any given day, you might be:

• Integrating and extending our next-generation mobile observability platform to unlock capabilities like session replay, remote workflows, and real-time alerting
• Building and evolving OpenTelemetry-based tracing infrastructure to give teams end-to-end visibility from mobile client to backend services
• Designing modular observability components (metrics, error reporting, logging) that make observability a first-class citizen in every Amazon mobile app
• Building systems to measure and alert on app stability, crash rates, ANRs, and feature health across Android and iOS
• Evaluating and integrating observability providers, defining evaluation criteria, running proof-of-concepts, and building abstraction layers that let us swap providers without disrupting hundreds of partner teams
• Working across both Android (Kotlin/Java) and iOS (Swift/Objective-C) codebases, building client-side SDKs and wrappers that thousands of engineers depend on daily
• Collaborating with performance, stability, and partner teams to define metrics, set SLAs, and drive down crash rates

You'll own projects end-to-end — from design through implementation, testing, and production rollout — and your work will directly impact the reliability and performance experience of hundreds of millions of Amazon customers.

About the team

The Mobile Observability team builds and operates the components, services, tools, and APIs that give app builders deep visibility into the health and behavior of their systems. We create the foundation for metrics and telemetry across the Amazon Shopping app.

We're a small, high-impact team within Mobile Shopping Foundation — the org that owns the core of the Amazon Shopping app and builds the foundation that feature teams build on top of. Our products span crash reporting, session replay, error reporting, distributed tracing, and stability metrics across Android and iOS.

We're in the middle of a major platform evolution: migrating to a next-generation observability platform, building modular observability components, and defining what mobile observability looks like across all of Amazon's mobile apps — not just Shopping. If you want to shape the future of how Amazon understands its mobile apps, this is the team.
