Senior Backend Engineer (Ruby on Rails), Monitor: Platform Insights

About This Role

As a Senior Backend Engineer on the Platform Insights team, you will build and evolve a unified data event platform for GitLab, providing actionable visibility into user workflows. You will work on high-scale, data-rich backend services to power dashboards, enabling teams to monitor service health, processes, and collaboration.

Responsibilities

• Lead the design and development of secure, well-tested, and performant backend features for the Platform Insights area, primarily using Ruby on Rails and PostgreSQL.
• Build and evolve high-scale, data-rich services and APIs that power the unified event and analytics platform, allowing users to query, visualize, and analyze data.
• Collaborate closely with Product Management, UX, and other engineering teams to understand use cases, shape technical solutions, and deliver a consistent dashboard and insights experience.
• Own complex projects end to end, from technical discovery and proof-of-concept implementations through architecture, delivery, deployment, observability, and ongoing maintenance.
• Design and optimize data models and pipelines, including analytical databases like ClickHouse, to support scalable, reliable, and low-latency analytics workloads.
• Advocate for and maintain high standards for code quality, style, reliability, and performance, and drive improvements to product quality, security, and operational excellence.
• Mentor and support other engineers through code reviews, pairing, and technical guidance, fostering best practices for backend development and distributed architectures.
• Partner with other GitLab teams to integrate monitoring, metrics, and insights into their product areas, utilizing system health data to iterate on platform capabilities.

Requirements

• Experience building backend services in production environments using Ruby on Rails and PostgreSQL, or comparable web frameworks and relational databases.
• Experience with analytical databases and large-scale data processing technologies (e.g., ClickHouse) and solid understanding of database fundamentals.
• Experience building, operating, and scaling complex platforms or applications, including designing distributed, scalable, and reliable backend systems.
• Experience building and deploying software using continuous integration and continuous delivery (CI/CD) pipelines.
• Experience operating services on a major cloud provider (GCP or AWS), including managed Kubernetes offerings (GKE or EKS), and using modern DevOps, monitoring, and observability tools (Prometheus or Grafana).
• Experience mentoring other engineers or contributing to technical decisions, collaborating effectively in a remote, largely asynchronous environment, and excellent written and verbal English communication skills.

Qualifications

• Experience building backend services in production environments, ideally supporting data-rich, high-scale applications, using Ruby on Rails and PostgreSQL, or comparable web frameworks and relational databases.

Nice to Have

• Demonstrated ability to quickly learn and be productive in new programming languages, such as Golang.
