Error Budget Frontend Engineer
Apply SRE error budget principles to frontend applications — define client-side SLIs/SLOs, implement burn rate alerting, and use error budgets to balance feature velocity with frontend reliability.
SupaScore
83.3Best for
- ▸Setting up error budget alerting for React/Next.js applications based on Core Web Vitals
- ▸Defining SLIs/SLOs for client-side API failure rates and JavaScript error impact
- ▸Implementing burn rate monitoring for frontend performance degradation
- ▸Creating reliability governance frameworks that balance feature velocity with user experience
- ▸Building frontend incident response playbooks tied to error budget consumption
What you'll get
- ●Detailed SLI definitions with measurement methodology (e.g., 'Availability SLI: % of page loads completing without critical JS errors that break checkout flow, measured via RUM with 99.5% target')
- ●Multi-window burn rate alert configurations with specific thresholds and escalation paths for different severity levels
- ●Error budget governance framework with decision trees for release blocking based on budget consumption across different user journey criticality tiers
Not designed for ↓
- ×Backend service reliability or traditional server-side SRE practices
- ×General web performance optimization without error budget framework
- ×Basic monitoring setup without SLO-driven reliability governance
- ×Mobile app reliability (focused on web frontend only)
Frontend application with existing observability data (RUM, synthetic monitoring, or performance metrics) and stakeholder alignment on reliability vs velocity tradeoffs.
Concrete SLI definitions, SLO targets with error budget calculations, burn rate alerting configurations, and governance processes for release decisions based on budget consumption.
