Job Summary

Your Career

We are looking for a Principal Software Engineer to architect, build, and evolve our observability platform across infrastructure, applications, and developer workflows. This role is ideal for a hands-on technical leader with deep experience in open source observability technologies and Chronosphere, who is equally fluent in building AI-enabled systems and developer experiences using modern AI coding tools such as Claude and Codex.

You will serve as a technical architect for the observability stack, working across engineering, platform, SRE, and product teams to define standards for metrics, logs, traces, profiling, synthetics, alerting, dashboards, and incident response. You will also lead the integration of AI agents, copilots, and skill-based automation into observability workflows — making telemetry, debugging, and reliability operations equally consumable by humans and AI agents. You should be comfortable operating at both strategic and implementation levels: designing architecture, writing production-grade code, reviewing systems, mentoring engineers, and driving adoption across teams.

Your Impact

Observability Architecture

• Design and lead the evolution of a modern observability platform using OpenTelemetry, Prometheus, Jaeger, Alertmanager, and related CNCF ecosystem tools.

• Define architecture standards for telemetry collection, processing, storage, querying, visualization, alerting, retention, and governance.

• Build scalable systems for metrics, distributed tracing, continuous profiling, log aggregation, synthetic monitoring, service health monitoring, and reliability analytics.

• Establish best practices for instrumentation across services, infrastructure, Kubernetes workloads, CI/CD systems, and developer platforms.

• Evaluate trade-offs around data cardinality, sampling, storage cost, retention, query performance, multi-tenancy, reliability, and operational complexity.

• Make pragmatic recommendations on open source, self-managed, managed-service, and hybrid observability approaches.

• Create paved-road observability patterns that help engineering teams instrument, monitor, debug, and operate services with minimal friction.

  OpenTelemetry and Instrumentation

• Lead adoption and standardization of OpenTelemetry across applications, services, infrastructure, and platform components.

• Design and implement telemetry pipelines using OpenTelemetry Collector, exporters, processors, receivers, connectors, and custom extensions where needed.

• Define conventions for traces, metrics, logs, spans, attributes, resources, service names, correlation IDs, and semantic conventions.

• Build libraries, SDK wrappers, golden paths, and internal tooling to simplify observability instrumentation for engineering teams.

  Metrics, Monitoring, and Alerting

• Architect metrics systems using Prometheus-compatible formats, PromQL, remote write, federation, scraping strategies, service discovery, recording rules, and long-term storage backends.

• Design alerting frameworks that reduce noise, improve signal quality, and align with SLOs, SLIs, error budgets, and incident response practices.

• Create reusable alerting patterns for Kubernetes, infrastructure, applications, APIs, databases, queues, event-driven systems, and distributed services.

• Define standards for dashboarding, runbooks, escalation policies, alert ownership, and production readiness.

• Partner with SRE and engineering teams to mature monitoring practices and improve service reliability.

  Kubernetes and Platform Engineering

• Build observability capabilities for Kubernetes environments, including cluster monitoring, workload telemetry, service mesh visibility, ingress and egress monitoring, and node-level insights.

• Develop and maintain Helm charts, Kubernetes manifests, operators, sidecars, agents, DaemonSets, and deployment automation for observability components.

• Work with platform teams to ensure observability systems are reliable, secure, multi-tenant, highly available, and easy to operate.

• Define standards for resource usage, scaling, upgrades, failover, backup, disaster recovery, access control, and tenant isolation for observability infrastructure.

• Support observability across multi-cluster, multi-region, and hybrid cloud environments where applicable.

  AI-Enabled Observability and Developer Experience

• Design and build AI-enabled observability workflows that allow both humans and AI agents to investigate incidents, query telemetry, summarize signals, and propose remediations.

• Define and publish reusable AI skills, agents, and tools (e.g., Claude skills, Codex tools, MCP servers, structured prompts) that encode observability best practices and make platform capabilities consumable by engineering teams and autonomous agents.

• Build paved-road AI integrations for triage, alert summarization, root-cause analysis, log/trace exploration, runbook generation, dashboard authoring, and post-incident review.

• Establish standards for grounding AI agents in authoritative telemetry, runbooks, and service catalogs, with strong guardrails around accuracy, safety, cost, and auditability.

• Use AI coding tools (Claude, Codex, and equivalents) as a first-class part of the engineering workflow — for code generation, refactoring, instrumentation rollouts, migrations, and platform automation — and define patterns the broader team can adopt.

• Partner with platform, SRE, and product teams to evolve observability from human-only dashboards toward agent-assisted, self-serve reliability operations.

Qualifications

Your Experience

• 7+ years of software engineering, platform engineering, infrastructure engineering, or SRE experience, with significant experience building production-grade distributed systems.

• Deep hands-on experience with observability systems, including metrics, logs, traces, profiling, dashboards, synthetics, alerting, and incident workflows.

• Strong expertise with OpenTelemetry, including SDKs, Collector pipelines, exporters, processors, receivers, semantic conventions, and instrumentation patterns.

 Success in This Role Looks Like

• The organization has a clear, scalable observability architecture with strong standards for telemetry generation, collection, storage, querying, retention, and consumption.

• Engineering teams can easily instrument services and get useful metrics, traces, profiles, logs, dashboards, synthetic checks, and alerts without deep observability expertise.

• Alerting becomes more actionable, less noisy, and better aligned with service health, SLOs, and customer impact.

• Synthetic monitoring proactively detects failures in critical user journeys, APIs, infrastructure endpoints, and third-party dependencies before customers are significantly impacted.

• The observability platform is reliable, cost-efficient, secure, multi-tenant, and easy to operate across Kubernetes environments.

• Continuous profiling and tracing become part of normal performance, debugging, and reliability workflows.

• AI agents and skills are first-class consumers of the observability platform — accelerating triage, investigation, and remediation for both humans and autonomous workflows, with measurable improvements in MTTR and engineer productivity.

• The Principal Engineer is recognized as the technical leader who can connect architecture, implementation, operational excellence, developer experience, AI-enabled workflows, and business reliability outcomes across the observability stack.
