About Job

Evolving our Python runtime and stack by improving performance, concurrency, memory use, and dependency management. Building and scaling core platform services that provide the foundation for reliability, scalability, and developer velocity across engineering. Optimizing storage systems for consistency, scale, and performance. Embedding observability and reliability patterns into the platform by default. Refactoring and modularizing large-scale codebases to maintain developer velocity and ensure our primary codebases remain a productive environment at scale. Partnering with product and infra teams to deliver platform APIs and abstractions that strike the right balance between velocity and long-term stability. Laying the groundwork for future platform needs, from global expansion to enabling new product capabilities.

Proven experience building or scaling messaging, notification, or caching systems.
Background in refactoring large codebases for scale, performance, and maintainability.
Hands-on with runtime and platform optimization such as concurrency models, async patterns, and memory tuning.
Familiarity with service reliability and observability practices such as metrics, tracing, circuit breakers, and failure isolation.
Comfortable operating in a cloud-native environment such as AWS or GCP with Kubernetes, Docker, and Terraform.
