Hiring playbook
How to hire JavaScript developers
JavaScript developers should pair UI craft with performance, accessibility, and reliable delivery habits.
Set 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.
Probe 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.
Validate 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.
Check 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.
Onboard with clear guardrails
- Share coding standards, performance budgets, and analytics schemas up front.
- Align on review cadence and quality gates in the first sprint.
