• Serves as a function-wide subject matter expert in one or more areas of site reliability, observability, or telemetry engineering.
• Leads resiliency design reviews and breaks up complex reliability problems into digestible work for other engineers, acting as a technical lead for large-sized products.
• Acts as the main point of contact during major incidents, demonstrating the skills to identify and solve issues quickly to avoid financial losses, and champions blameless postmortem culture.
• Collaborates with team members and stakeholders to define comprehensive service level indicators, service level objectives, and error budgets.
• Designs, implements, and maintains operational reliability for large-scale OpenTelemetry pipelines on hybrid on-prem/cloud environments, supporting telemetry ingestion, processing, and export to backends such as InfluxDB, Prometheus, Elasticsearch, and OpenSearch.
• Drives the assessment, refactoring, and incremental migration of custom legacy telemetry collection code to standardized OpenTelemetry instrumentation, reducing technical debt while maintaining system stability.
• Actively contributes to the engineering community as an advocate of firmwide frameworks, tools, and practices, and influences peers and project decision-makers to consider the use and application of leading-edge observability and reliability technologies.
• Adds to the team culture of diversity, opportunity, inclusion, and respect.

Required qualifications, capabilities, and skills

• Formal training or certification on software engineering concepts and advanced applied experience delivering system design, application development, testing, and operational stability.
• Advanced knowledge of reliability, scalability, performance, security, enterprise system architecture, toil reduction, and other site reliability best practices, with considerable in-depth knowledge in one or more technical disciplines (e.g., cloud, observability, distributed systems, etc.).
• Advanced proficiency in one or more programming languages (e.g., Java, Python, Go, etc.).
• Advanced proficiency and experience in observability such as white and black box monitoring, SLO alerting, and telemetry collection using tools such as Grafana, Dynatrace, Prometheus, Datadog, Splunk, Elasticsearch, etc.
• Proficiency in continuous integration and continuous delivery tools (e.g., Jenkins, GitLab, Terraform, etc.).
• Experience with container and container orchestration (e.g., ECS, Kubernetes, Docker, etc.).
• Hands-on experience with the design, deployment, and operation of OpenTelemetry collectors in production environments, focusing on technical aspects such as configuring, optimizing, and troubleshooting OTLP endpoints and receivers.
• Ability to tackle reliability design and functionality problems independently with little to no oversight.
• Practical cloud native experience.
• Ability to expand and collaborate across different levels and stakeholder groups.

Preferred qualifications, capabilities, and skills

• Knowledge of distributed tracing, metrics, and logging best practices.
• Certification in AWS, Kubernetes, or relevant technologies.
• Proven track record in system health monitoring, capacity management, and blameless postmortems for high-availability services.
• Deep understanding of distributed system design principles, networking (TCP/IP, DNS, load balancing), and Linux internals.
• Contributions to open-source observability or telemetry projects.
• Experience working with agent control planes and management protocols; hands-on knowledge of OpAMP is highly desirable.
