📋 Description

• Architect, design, and build resilient and scalable systems for delivering feature flag data globally, optimized for high availability and low latency — single-digit milliseconds within regions. • Own and evolve core components such as our global edge delivery network, streaming infrastructure, and data synchronization protocols. • Drive improvements in system availability, performance, and operational excellence by identifying bottlenecks and designing for failure. • Collaborate cross-functionally with infrastructure, SDK, product, and security teams to deliver seamless and secure customer experiences. • Mentor and lead other engineers by modeling best practices in distributed systems development, code quality, and systems thinking. • Take initiative in incident response and post-incident reviews, continually improving system reliability and observability. • Participate in an on-call rotation for the services you help build, and demonstrate a strong sense of ownership and accountability for their uptime and reliability.

🎯 Requirements

• Proven experience in architecting, building, and operating complex, large-scale backend and infrastructure services, with a multi-year, hands-on focus specifically on distributed systems. • Deep understanding of event-driven architectures, streaming protocols (e.g., Server-Sent Events, WebSockets), and stateful connection management at scale. • Expertise in Go, Java, Rust or similar systems programming languages. (We use Go and a little bit of Rust.) • Familiarity with real-time data pipelines, load balancing, and global edge networks/CDNs. • Proven experience in monitoring, observability, and operational excellence — designing systems with robust telemetry and actionable alerting to meet SLOs for low latency and high availability. • Experience operating systems in cloud environments (e.g., AWS, GCP) using infrastructure-as-code tools • Experience working with distributed data stores and caching systems (e.g., Redis, DynamoDB, Kafka, Varnish and similar). • Proven history of technical leadership: setting direction, breaking down complex problems, and influencing outcomes across teams.
