Senior Software Engineer, Platform Observability Remote

OverviewAt Twilio, we're shaping the future of communications with a remote-first culture.We deliver innovative solutions to hundreds of thousands of businesses and empower millions of developers to craft personalized customer experiences.This role is for a Software Engineer on Twilio's Platform Observability team, focused on rebuilding and unifying our observability stack to enable faster incident response, deeper insights, and more cost-effective platform operations.You'll help re-architect how telemetry flows and is utilized at Twilio—making it structured, accessible, affordable, and actionable.Over the next 3 years, Twilio is rebuilding nearly every component of our observability platform, from data collection to real-time analytics.You will drive core initiatives that move Twilio from fragmented tooling to a unified, OpenTelemetry-first observability stack built for scale.You'll lead technically and strategically—designing platform components, influencing architectural decisions, mentoring engineers, and engaging with teams across Platform Engineering and R&D.ResponsibilitiesLead 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.Deeply explore 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.QualificationsTwilio values diverse experiences from all kinds of industries, and we encourage
