DevOps Engineer (Observability)

Stack

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 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

Requirements

• ▹Proven expertise in building and scaling observability systems (e.g. logging platforms, metrics pipelines, tracing infrastructure or profiling tools)
• ▹Lead technical execution for major components of Twilio's observability overhaul, including the shift to centralized S3-based data lakes, OpenTelemetry instrumentation and ClickHouse-backed query engines
• ▹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)
• ▹Solid understanding of distributed systems and the challenges of observability in complex, microservice-based environments
• ▹Experience with AWS, Kubernetes and infrastructure-as-code tools
• ▹Provide architectural guidance and thought leadership across teams, helping to establish clear telemetry standards, efficient usage patterns and scalable platform abstractions
• ▹Ability to make forward-looking technical decisions and lead others through ambiguity and change

Nice to have

• ▹Familiarity with ClickHouse, Grafana Mimir, Athena or equivalent systems for log and metrics querying
• ▹Contributions to open-source observability tools or communities
• ▹Experience building cost visibility or FinOps tooling for cloud compute and telemetry pipelines
