Trusted by 200,000+ organizations, Sentry is today’s application monitoring standard and our team is building its AI-native future.

About the role

Sentry.io provides a suite of services to diagnose health problems in their customers’ applications. These tools are mission‑critical to companies who want to respond effectively in fast‑paced markets. We make the development and deployment of these tools a safe and enjoyable experience, by maintaining a succinct and helpful continuous integration environment and an informative deployment pipeline.

The Centralized Tenancy and Routing Layer (CTRL) team builds and operates the foundational infrastructure that defines customer boundaries and coordinates lifecycle operations across Sentry’s distributed architecture. These systems power how customers are managed and how services communicate and replicate data safely across our ecosystem.

As a Senior Software Engineer on the CTRL team, you’ll design and operate the core platform primitives that make this architecture possible. Your work will focus on distributed coordination, cross‑cell routing, replication infrastructure, and lifecycle orchestration for the customer environment. This role sits at the heart of Sentry’s platform architecture—building the control systems that ensure the platform operates safely and correctly at global scale. The work requires strong engineering judgment and deep distributed systems thinking. You’ll design systems where correctness and reliability are critical, and build abstractions that many teams depend on but rarely see directly.

Ultimately, you’ll help build the infrastructure that enables Sentry’s SaaS platform to scale safely across a distributed, multi‑cell architecture.

In this role you will

• Build and enhance the control plane systems that manage customer identity, placement, and lifecycle across a multi‑cell architecture.
• Improve the reliability, scalability, and observability of mission‑critical control plane services.
• Partner with engineering teams to provide safe infrastructure primitives and standards for cell‑compatible systems.
• Help operate critical infrastructure through incident response and continuous improvement.

You’ll love this job if you

• Enjoy building foundational distributed systems that power an entire platform.
• Care deeply about correctness, reliability, and safe infrastructure primitives.
• Like designing systems that coordinate state and data across large distributed environments.
• Prefer solving architectural problems rather than product feature work.
• Want to shape how a global platform evolves as it scales.

Qualifications

• 5+ years of experience as a Software Engineer or similar role.
• Strong proficiency with Python; experience with Rust is a plus.
• Experience designing and operating distributed systems at scale.
• Strong understanding of replication, consistency models, and service coordination.
• Experience building infrastructure services or platform APIs used by multiple teams.
• Experience working with cloud platforms (e.g., AWS, Azure, GCP).
• Experience operating containerized systems (e.g., Docker, Kubernetes).
• Track record of operating production systems with strong ownership.
• Strong written communication skills and ability to document platform systems clearly.
