Hiring playbook

How to hire JavaScript developers

JavaScript developers should pair UI craft with performance, accessibility, and reliable delivery habits.

01Set performance and accessibility targets

Define Core Web Vitals, WCAG level, and SEO goals before interviews.

Ask for examples of meeting these targets without slipping timelines.

02Probe architecture and integration sense

Discuss routing, state, and data-fetching choices for your use case.

Look for awareness of API contracts, error handling, and backward compatibility.

03Validate testing and delivery discipline

Review their approach to unit, integration, and e2e tests plus CI/CD gates.

Great candidates have stories of preventing regressions during fast releases.

04Check collaboration with design and QA

Strong JS engineers pair in design tools, run design QA, and keep QA aligned on acceptance criteria.

Documentation and async comms should be part of their toolkit.

05Onboard with clear guardrails

Share coding standards, performance budgets, and analytics schemas up front.

Align on review cadence and quality gates in the first sprint.
