Twilio is seeking a Principal Software Engineer to lead the transformation of its connectivity observability platform into a cohesive, telco-grade system. This individual will play a critical role in unifying our tooling, improving data quality and latency, and enabling real-time, actionable insights across Messaging, Voice, and Email products.
Requirements
- 10+ years of software or platform engineering experience, including deep expertise in observability, data infrastructure, or connectivity systems.
- Proven experience architecting real-time data systems or observability platforms at scale.
- Strong background in building or integrating monitoring and visualization tools (Grafana, OpenSearch, Zabbix, SNES, etc.).
- Proficiency in SQL, Python, or Scala, and data frameworks like Spark, Flink, or Kafka.
- Experience applying ML techniques in observability or anomaly detection.
- Understanding of telecom or carrier-based systems and network-layer traffic monitoring
- Experience with multi-tenant, customer-segmented observability systems.
Responsibilities
- Define and lead the strategy for Twilio's next-generation connectivity observability platform, focusing on unifying tools and standardizing data pipelines.
- Drive the consolidation of fragmented monitoring systems (e.g., Zabbix, SNES, Grafana, Voice Insights) into a single pane of glass for voice and messaging traffic insights.
- Architect scalable, real-time data pipelines to support on-demand slicing, correlation, and anomaly detection across carriers and customers.
- Partner with data engineering and ML teams to implement pragmatic AI/ML-based detection models, prioritizing actionable accuracy over theoretical complexity.
- Champion data quality improvements—ensuring high completeness, reduced latency, and enriched data with customer and carrier metadata.
- Build and maintain a SQL-like interface or data exploration layer to democratize access to observability data for engineers, analysts, and incident response teams.
- Lead design reviews, influence tooling decisions, and mentor engineers across platform and product teams.
Other
- Demonstrated success working cross-functionally in large organizations to align platform vision with product and operational needs.
- This role will be remote, but is not eligible to be hired in San Francisco, CA, Oakland, CA, San Jose, CA, or the surrounding areas.
- For this role, you may be required to travel occasionally to participate in project or team in-person meetings.
- 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.
