Senior Software Engineer, Foundational Storage

Details

Sentry's Foundational Storage team builds and supports the stateful storage systems that its products rely on, including object storage, relational databases, key-value stores, and caches. The team develops storage services such as the open-source Objectstore and builds libraries and APIs that make storage systems easier to use. The role focuses on data consistency, availability, performance, security, and cost efficiency across distributed systems.

Responsibilities

• Design and operate storage systems used across Sentry, including configuration and performance tuning.
• Create APIs and abstractions that make storage easy for product teams to use, with best practices for correctness, security, and scale built in.
• Solve storage challenges at scale, including consistency under concurrent access, sharding and rebalancing, and routing reads and writes across storage backends.
• Work with product engineers to choose storage approaches, plan safe migrations, and help teams adopt new tools.
• Plan and build with Platform and Infrastructure teams, including analytical storage and streaming teams, to deliver a complete, fault-tolerant platform.
• Align roadmaps and standards, and design for failures and recovery.
• Improve storage performance and cost efficiency while keeping the platform simple for product teams.
• Write code primarily in Rust and Python, with clear user-facing documentation.
• Develop advanced testing scenarios, including production-scale chaos tests covering backend and infrastructure outages.
• Own latency and availability SLOs, improve monitoring and incident response, and participate in the team's on-call rotation.
• Contribute to open-source projects as part of the role.

Requirements

• 5+ years of software engineering experience building and operating distributed, stateful systems in production.
• Hands-on experience with object storage, relational databases, and caching systems at production scale.
• Experience with key-value or wide-column stores is a plus.
• Understanding of distributed systems fundamentals, including consistency, concurrency, request failures, and retries.
• Proficiency in a systems language such as Go, C++, Java, or Rust, and comfort working in Python. Sentry primarily uses Rust and Python and welcomes engineers who are new to Rust.
• Experience running services on Kubernetes in a cloud environment, including observability, SLOs, and incident response.
• Familiarity with Terraform is a plus.
• Good written and spoken English, particularly for explaining technical choices and writing documentation.
• Nice to have: experience building shared libraries or internal APIs, migrating data between systems, or improving system performance and cost.
