• Proven experience as a senior or principal engineer in distributed, large-scale, or high-availability systems.
• Deep technical knowledge in at least one of the following: performance optimization, observability, fault-tolerant architecture, chaos testing, or cloud-native design.
• Demonstrated success leading cross-team engineering efforts that drive measurable system improvements.
• Familiarity with CI/CD pipelines, infrastructure as code, and modern observability stacks.
• A track record of delivering robust systems in environments focused on scale, uptime, and performance.
• A strong track record of driving cross-team collaboration, resolving complex technical challenges, and translating broad business problems into elegant engineering solutions.
• Strong, structured communication and collaboration skills, with the ability to influence architectural decisions across technical and non-technical stakeholders and effectively document outcomes.
