Software Engineer (Observability)

Join Twilio's Platform Observability team as a Software Engineer. You'll play a critical role in re-architecting how telemetry flows and is utilized throughout the company. This position involves leading the end-to-end architecture and delivery of key observability platform components, driving consistency and quality across all observability signals, and serving as a technical advisor and mentor across the platform organization. You'll collaborate with product teams, SREs, and developer experience groups to understand telemetry needs and integrate observability into core engineering workflows.

• Conduire l'architecture et la livraison de composants clés de la plateforme d'observabilité, en mettant l'accent sur la fiabilité, l'évolutivité et l'utilisabilité.
• Diriger des initiatives clés qui font passer Twilio d'outils fragmentés et d'une prolifération de données coûteuses à une pile d'observabilité unifiée, axée sur OpenTelemetry.
• Collaborer avec des équipes produit, des SRE et des groupes d'expérience développeur pour comprendre en profondeur les besoins en télémétrie et intégrer l'observabilité dans les flux de travail d'ingénierie.

• Familiarity with high-cardinality data challenges and telemetry correlation techniques
• 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)
• Provide architectural guidance and thought leadership across teams, helping to establish clear telemetry standards, efficient usage patterns, and scalable platform abstractions
• Experience designing high-scale telemetry systems (e.g., Prometheus, ClickHouse, OpenTelemetry, Kafka, or equivalent)
• Ability to make forward-looking technical decisions and lead others through ambiguity and chan
• Experience with AWS, Kubernetes, and infrastructure-as-code tools
• Lead technical execution for major components of Twilio’s observability overhaul, including our shift to centralized S3-based data lakes, OpenTelemetry instrumentation, and ClickHouse-backed query engines
• Twilio values diverse experiences from all kinds of industries, and we encourage everyone who meets the required qualifications to apply. If your career is just starting or hasn't followed a traditional path, don't let that stop you from considering Twilio. We are always looking for people who will bring something new to the table!
• Solid understanding of distributed systems and the challenges of observability in complex, microservice-based environments
• 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
