• Experience designing highly available systems and safe production rollouts using practices such as canaries, progressive deployments, and feature flags.
• Strong ownership and sound technical judgment, with the ability to navigate ambiguity and drive complex problems to durable resolution.

Responsibilities

• Design and implement DNS data plane components across authoritative and recursive request paths, emphasizing low-latency, high-throughput processing.
• Build services and libraries in Go, C, Java, or Python, selecting the appropriate language and approach for each component’s performance and operational requirements.
• Optimize CPU, memory, and network I/O through efficient event loops, concurrency models, socket tuning, profiling, and benchmarking.
• Own data plane components end to end, including architecture, implementation, testing, safe rollout, observability, capacity planning, and ongoing operational health.
• Develop and maintain metrics, logs, traces, SLOs, dashboards, alerts, and practical on-call playbooks.
• Improve reliability through fault-tolerant design, graceful degradation, safe deployment practices, and proactive capacity planning.
• Collaborate with control plane, security, SRE, and operations teams to deliver end-to-end DNS platform improvements.
• Provide technical leadership through architecture reviews, code reviews, and mentorship, raising engineering standards across the team.
