Senior Software Engineer – Observability (Golang) in Cambridge

About the Role

You will work on core observability systems (metrics, logs, traces) while also developing robust data pipelines and storage solutions optimized for high throughput, performance, and cost. You’ll leverage technologies such as time-series databases (TSDB), columnar storage formats (e.g., Parquet), and distributed data processing frameworks to advance the platform’s capabilities. Collaboration with cross-functional teams will be critical, as you’ll integrate observability into Roku’s cloud-native stack and contribute improvements back to the open-source community.

• Extend and integrate open-source observability systems, and when needed, structurally overhaul core components, such as storage layers and query paths, to improve performance, reliability, and usability of these tools at scale.
• Build services to improve performance, usability, reliability, and cost efficiency.
• Implement features like pre-aggregation, downsampling, and sampling to reduce load and accelerate queries.
• Create developer-facing capabilities for metrics, logs, and traces usage, data quality, and cost management.
• Automate onboarding, dashboards, alerting, and tracing.
• Collaborate across platform and infrastructure teams to integrate observability into Roku’s cloud-native stack.

What We’re Looking For

• Extensive experience in software engineering building distributed, high-throughput systems or observability platforms.
• Hands on Go experience; our observability ecosystem is Go-based, making it the most effective language for this role.
• Experience with, or strong interest in, observability tools (Prometheus, Grafana, Loki, Tempo, ELK/OpenSearch, Clickhouse) and standards (OpenTelemetry, OpenTracing, OpenMetrics).
• Deep understanding of distributed systems and data models.
• Hands-on experience with Kubernetes, and cloud platforms (AWS, GCP, Azure).

The Roku Culture

Roku is a great place for people who want to work in a fast-paced environment where everyone is focused on the company's success rather than their own. We try to surround ourselves with people who are great at their jobs, who are easy to work with, and who keep their egos in check. We appreciate a sense of humor. We believe a fewer number of very talented folks can do more for less cost than a larger number of less talented teams. We’re independent thinkers with big ideas who act boldly, move fast and accomplish extraordinary things through collaboration and trust. In short, at Roku you’ll be part of a company that’s changing how the world watches TV.

We have a unique culture that we are proud of. We think of ourselves primarily as problem-solvers, which itself is a two-part idea. We come up with the solution, but the solution isn’t real until it is built and delivered to the customer. That penchant for action gives us a pragmatic approach to innovation, one that has served us well since 2002.
