• Drive consistency and quality across logs, metrics, traces, and continuous profiling.
• Act as a technical advisor and mentor across the platform org on architectural design decisions.
• Design and build developer-friendly tooling and APIs for incident response, performance analysis, and debugging.
• Collaborate with product teams, SREs, and developer experience groups to integrate observability into engineering workflows.
• Leverage open-source standards like OpenTelemetry to ensure interoperability and extensibility.

What you'll need

• Lead technical execution for major components of Twilio’s observability overhaul, including centralized S3-based data lakes, OpenTelemetry instrumentation, and ClickHouse-backed query engines.
• Proficiency in at least one modern programming language (Go, Python, or Java).
• Familiarity with high-cardinality data challenges and telemetry correlation techniques.
• Experience designing high-scale telemetry systems (Prometheus, ClickHouse, OpenTelemetry, Kafka, or equivalent).
