Site Reliability Engineer - Front-End (Performance & Optimization)

Job Description:
We are seeking a Site Reliability Engineer - Front-End (Performance & Optimization), who combines strong front-end development expertise with a passion for performance optimization and data-driven improvements. This role is highly consultative, working across teams to identify, diagnose, and improve front-end performance issues that directly impact business outcomes.
This is not a traditional “build UI” role — instead, you will analyze, recommend, and influence improvements across the front-end ecosystem, with the opportunity to become hands-on over time.
Key Responsibilities:
Performance Analysis & Optimization:

Analyze front-end performance across web applications (e.g., page load speed, Core Web Vitals, TTFB)
Identify performance bottlenecks across the front end, CDN, and edge layers
Translate performance data into actionable insights tied to business metrics (conversion, engagement, etc.)

Consultative Engineering:

Partner with product and engineering teams to:
Recommend code-level and architectural improvements
Guide teams on best practices for front-end performance
Act as a subject matter expert bridging performance data and engineering execution

Cross-Functional Collaboration:

Work closely with engineering, product, and analytics teams
Support teams during implementation of recommendations
Participate in discussions to improve overall system performance strategy

Hands-On Contribution (Optional / Evolving):

Opportunity to:

Contribute code improvements (PRs)
Join sprint teams temporarily to implement optimizations
Level of hands-on work will grow based on team maturity and candidate capability

Required Skills & Experience:
Core Technical Skills

Strong experience in front-end development (React required)
Deep understanding of:
Core Web Vitals
Front-end performance optimization techniques
Browser rendering and page lifecycle
Experience working with APIs and understanding backend interactions

Performance & Observability:

Experience diagnosing performance issues using tools and metrics
Ability to connect technical performance → business impact

Architecture Awareness:

Understanding of:

Front-end architecture
CDN behavior and caching strategies
Edge performance optimization

Nice to Have:

Experience with CDNs and edge caching
Exposure to performance monitoring/observability platforms
Prior experience in a performance engineering or optimization-focused role
Ability to contribute code when needed (not mandatory but preferred)

Soft Skills (Critical for Success):

Strong communication and collaboration skills
Ability to influence without direct ownership
Comfortable working in a consultative, cross-team environment
Adaptability to evolving technologies (automation, AI-driven processes)

What This Role Is / Is Not:
This role IS:

Data-driven and performance-focused
Cross-functional and consultative
Focused on improving existing systems

This role IS NOT:

A pure front-end feature development role
A siloed engineering position
Manual or repetitive work — emphasis is on automation and optimization

Rate: $60-$70/hour (depends on experience level). This is a contract position with candidates expected to work 40 hours/ week.
