Work Location Expectations: Hybrid with 3 days in office per week from our Austin, TX or Columbus, OH.
What you'll do:
Architecture & Performance
- Design and maintain high-performance Vue 3 + Server-Side Rendered (SSR) applications.
- Optimize SSR pipelines for speed, memory efficiency, and scalability.
- Improve Core Web Vitals (LCP, FCP, CLS, INP, TTFB) across large-scale web applications.
- Reduce hydration cost and improve Time to Interactive.
- Design and implement effective SSR/CSR hybrid rendering strategies.
- Optimize bundle splitting, dynamic imports, and tree-shaking.
JavaScript & Runtime Optimization
- Profile JavaScript execution using Chrome DevTools, Lighthouse, WebPageTest, and real-user monitoring tools.
- Analyze flame graphs, CPU profiles, and memory snapshots to eliminate hot paths and leaks.
- Deeply understand browser rendering pipelines, event loops, microtasks vs. macrotasks.
- Optimize reactivity systems, large lists, computed properties, watchers, and composables.
- Improve Node.js SSR throughput, concurrency handling, and caching strategies.
- Implement advanced caching approaches (HTTP, CDN, in-memory, edge caching).
SEO & Rendering Strategy
- Ensure SSR output is crawlable, indexable, and structured correctly for search engines.
- Optimize structured data, meta tags, and pre-render strategies.
- Balance performance improvements with SEO and discoverability goals.
- Partner with SEO and product teams to align technical implementation with organic growth strategy.
AI-Native Engineering & Workflow
- Use AI-assisted coding tools (e.g., Claude Code, GitHub Copilot, Cursor) as part of the daily development workflow to accelerate implementation, refactoring, and debugging.
- Apply agentic and AI-native workflows to routine engineering tasks — code review prep, test generation, documentation, and performance profiling — to increase team velocity.
- Evaluate and adopt emerging AI-powered developer tooling, contributing to team standards and best practices for AI-assisted development.
Engineering Excellence & Collaboration
- Write clean, maintainable, well-tested JavaScript code.
- Participate in architectural discussions and technical decision-making.
- Perform thoughtful code reviews and help raise the quality bar.
- Mentor mid-level and junior engineers on performance and front-end best practices.
- Collaborate cross-functionally with product managers, designers, backend engineers, and SEO specialists — many of whom are on remote and distributed teams — using async-friendly communication (written specs, recorded walkthroughs, thorough PR descriptions) alongside live collaboration.
- Contribute to a culture that values ownership, learning, and continuous improvement.
