Full Stack Engineer, Observability

About the Job:

LaunchDarkly is looking for a Full Stack Engineer to help close critical enterprise capability gaps in our Observability product. Observability has strong post-acquisition momentum—we're executing large-scale migrations, shipping net-new capabilities, and building an enterprise pipeline—and we need engineers who can own the work that makes us credible at the enterprise level.

This role focuses on two high-impact areas: Infrastructure-as-Code support for Observability (dashboards, alerts, configuration) and deeper integration with the tools enterprises already use—from event ingestion and data import/export to alert routing into systems like Jira and Linear. These are the gaps we repeatedly encounter in enterprise deals, and your work will directly influence our ability to win and expand accounts.

Responsibilities:

• Design and build full-stack features that address enterprise adoption requirements across Observability
• Own integrations and infrastructure capabilities end-to-end—from API design and backend services to UI surfaces
• Collaborate with product managers, designers, solutions engineers, and customers to understand enterprise requirements and deliver against them
• Participate in architecture and design discussions, making well-reasoned trade-offs for scalability, reliability, and maintainability
• Write well-tested, observable code and uphold high engineering standards across the team
• Engage with internal stakeholders and occasionally enterprise customers to validate solutions and gather feedback
• Participate in on-call rotations and maintain production reliability for your features

What You'll Work On

• Infrastructure-as-Code for Observability

• Make dashboards, alerts, and configuration deployable, version-controlled, and auditable
• Support standard enterprise workflows: peer review, rollback, compliance, and GitOps-style delivery
• Reduce adoption friction for organizations with mature DevOps practices

• Integrations

• Build data import and export pipelines connecting O11y to other event tracking and observability solutions
• Connect O11y Alerts to issue trackers (Jira, Linear, PagerDuty, etc.) to close the loop on incident workflows
• Design extensible integration patterns that support a growing ecosystem of enterprise tooling

About You:

• 5+ years of professional software engineering experience shipping production-quality full-stack features
• Proficiency across the stack—comfortable in TypeScript/React on the frontend and Go (or similar) on the backend
• Experience building integrations, data pipelines, or APIs that connect systems at scale
• Familiarity with Infrastructure-as-Code tooling (Terraform, Pulumi, etc.) or experience building IaC-compatible APIs
• Understanding of enterprise software requirements: compliance, auditability, RBAC, and GitOps workflows
• Strong communication skills—you can work across functions and are comfortable interacting with technical customers or solutions engineers
• Experience with observability tools (Datadog, Grafana, OpenTelemetry, etc.) is a plus
• Familiarity with LaunchDarkly's feature flagging or Observability product is a plus
