The ideal candidate is a full-stack engineer comfortable with React components, backend services, production releases, and on-call duties, collaborating with product managers, designers, and other developers to ship features that improve site quality and

Qualifications

3+ years in a full-stack or frontend role, with proven TypeScript and React depth (component architecture, performance, state management) and hands-on backend experience shipping and operating production services.
Production experience with Node.js, Python, or Go — enough to build, deploy, debug, and maintain backend services independently.
Experience owning CI/CD pipelines (GitHub Actions, Jenkins, or equivalent) end-to-end, including front-end build tooling, bundle optimization, and deployment automation without a dedicated ops team.
A proven track record of using AI to accelerate development, debug complex systems, and optimize code, while still owning the final outcomes.
Experienced in building for high availability and scalability at real production scale, including writing secure code, identifying vulnerabilities, and resolving security issues under pressure.
Ability to work autonomously in a globally distributed team.

Responsibilities

Own features across the full stack from component design and backend services to deployment pipelines and ship production code end-to-end.
Instrument client-side performance (Core Web Vitals, error tracking, real-user monitoring) alongside backend logging, metrics, tracing, alerting, and dashboards.
Partner with product managers, designers, and other developers to build, test, and release features for elastic.co.
Write clean, maintainable code and take ownership for its behavior in production.
Triage, investigate, and resolve security vulnerability reports — from reproduction and root-cause analysis to fix, validation, and coordinated disclosure.
Participate in code reviews for your team.
Diagnose and resolve production issues spanning client regressions to backend failures, and participate in an on-call rotation for an always-on service.
