Fullstack Software Engineer II - Admin UX - Platform Applications

Elastic, the Search AI Company, enables users to find answers in real time across structured and unstructured data through its cloud-based search, security, and observability solutions. The Software Engineer II will build and operate full-stack product features for the Platform Admin UX team across React interfaces and backend services, while supporting production operations, testing, security, and cross-functional collaboration.

Responsibilities:

• Design, build, and ship full-stack product features, from React UI through the backend services that support them
• Own end-to-end delivery across multiple product variants and environments, using feature flags to gate incomplete work and ensure every release remains stable and deployable
• Operate services in production: participate in the release rotation, triage alerts, and maintain continuous delivery and quality gates
• Collaborate with product management and UX/UI designers to ensure admin experiences align with business goals; translate design prototypes into polished, accessible interfaces
• Conduct code reviews that uphold engineering standards, drive architectural improvements, advocate for automated testing, and provide constructive feedback that raises quality across the team
• Keep the platform safe and current: review dependency upgrades, investigate security vulnerabilities, manage feature flags, and extend synthetic test coverage when behavior changes

Requirements:

• 5+ years of full-stack development experience with React, TypeScript, JavaScript, HTML, and CSS
• Comfortable with Redux-style state patterns and modern data-fetching, with sound judgment about sharing vs. specializing UI across product variants. Solid command of Git and version control workflows
• Proven ownership of Node.js services in production: HTTP APIs, auth/session boundaries, configuration management, and debugging real incidents from logs, metrics, and traces
• Proficient with AI development tools (e.g. Cursor, Claude, or equivalent); you actively look for opportunities to accelerate your own workflow and the team's — while maintaining code quality and owning the outcomes
• Operational maturity — you have been on-call for a user-facing service, used runbooks and SLOs, and treat continuous delivery, feature flags, and automated tests as first-class parts of the feature
• Testing discipline using React Testing Library (or equivalent) and E2E/synthetics for critical paths; you write tests that protect behavior across environments without blocking release velocity
• Experience with DevOps practices and tooling; comfort in a multi-environment, compliance-aware product matrix — recognizing blast radius and shipping carefully behind flags
• Solid communicator and collaborator: you write clearly, give constructive code reviews, mentor peers, and work successfully with product and design
• Eligible to work in Department of Defense (DoD) Impact Level 4 or above cloud service environments
