As a DevOps Engineer on the Platform Observability team, you'll play a critical role in re-architecting how telemetry flows and is utilized through Twilio,making it structured, accessible, affordable, and actionable.

Responsibilities:

• Lead the end-to-end architecture and delivery of key observability platform components, with a focus on reliability, scalability, and usability.
• Drive consistency and quality across all observability signals,logs, metrics, traces, and continuous profiling,building intuitive workflows for engineers.
• Serve as a technical advisor and mentor across the platform org, guiding design decisions and aligning cross-team efforts with long-term architectural goals.
• Go deep in one or more problem areas (e.g., high-cardinality telemetry, distributed tracing correlation, compute cost insights), while ensuring the platform scales horizontally.
• Collaborate with product teams, SREs, and developer experience groups to deeply understand telemetry needs and integrate observability into core engineering workflows.
• Design and build developer-friendly tooling and APIs to support incident response, performance analysis, and platform debugging at scale.
• Leverage (and optionally contribute to) open-source standards like OpenTelemetry to ensure interoperability and extensibility.
• Champion a pragmatic approach to observability,balancing performance, cost, and user value across diverse engineering teams.

Qualifications:

• Proven expertise in building and scaling observability systems (e.g., logging platforms, metrics pipelines, tracing infrastructure, or profiling tools).

• Proficiency in at least one modern programming language (e.g., Go, Python, Java).
• Familiarity with high-cardinality data challenges and telemetry correlation techniques.
• Experience designing high-scale telemetry systems (e.g., Prometheus, ClickHouse, OpenTelemetry, Kafka, or equivalent).
