Senior Software Engineer - Cloud Infrastructure & Observability

• Architect and lead Roku’s observability platform across metrics, logs, and traces
• evolve data pipelines and storage layers optimized for high throughput, performance, and cost at Roku scale (TSDBs, Parquet, distributed processing)
• Extend and harden open-source observability systems
• overhaul core components (e.g., storage layers, query paths) to improve performance, reliability, and usability at scale
• Implement features such as pre-aggregation, down-sampling, and sampling to reduce load and accelerate queries across the platform
• Collaborate across platform, SRE, and product teams to migrate hundreds of workloads to our common platform
• augment and automate CI/CD flows and onboarding
• Integrate security into infrastructure and platform services
• ensure robust multi-tenant, multi-cluster, and multi-cloud designs
• Contribute improvements back to open source and CNCF-aligned projects
• shape standards adoption (OpenTelemetry, OpenMetrics) across the company
• Mentor engineers
• establish best practices for reliability, efficiency, and cost management across service mesh and observability domains

• Extensive experience with software engineering with a track record of architecting distributed systems or platforms at scale
• Strong hands-on experience in Golang and one scripting language (e.g., Python or Shell)
• Experience operating observability at pb-scale ingestion and hundreds of millions of series
• Expertise in observability platforms and tooling (Prometheus, Grafana, Loki, Tempo, ELK/OpenSearch, ClickHouse) and standards (OpenTelemetry, OpenMetrics)
• Deep experience building systems of scale and operating cloud infrastructure with Kubernetes
• strong proficiency with service mesh technologies (Istio/Envoy), infrastructure-as-code (Terraform) and experience in multi-cloud (AWS, GCP)
• Demonstrated ability to evolve storage and query architectures for cost, scale, and latency (e.g., TSDB, Parquet, distributed processing)
• Proven experience integrating security as part of infrastructure and platform development
• Exceptional cross-functional communication
• effective collaboration with both technical and non-technical stakeholders
• Culture fit: independent thinker, pragmatic problem-solver, low-ego collaborator who moves fast and focuses on company success
• Experience integrating AI tools to improve processes and reduce toil
• Open-source contributions in CNCF projects is preferred but not mandatory

Open-source contributions in CNCF projects

• Global access to mental health and financial wellness support and resources
• healthcare (medical, dental, and vision)
• life, accident, disability, commuter, and retirement options (401(k)/pension)
• time off work for vacation and other personal reasons
