About the Role
We’re hiring a senior Full-Stack Engineer focused on Growth to work on Jobscan, a multi-domain SaaS product helping job seekers optimize resumes using data, rules-based logic, and AI.
This is an end-to-end ownership role across product and marketing surfaces. You’ll build and optimize systems that drive user acquisition, activation, and conversion - spanning landing pages, SPA UI, APIs, and infrastructure — then iterate based on data.
What We’re Looking For
A product-minded engineer who can turn ambiguous growth problems into measurable, shipped improvements. You should:
- Make strong trade-offs between speed, quality, and cost
- Be comfortable running experiments and iterating quickly
- Understand how technical decisions impact conversion, SEO, and user behavior
- Communicate clearly in English and Mandarin
Core Responsibilities
- Build and optimize high-impact user flows (landing → signup → activation → conversion)
- Instrument and run A/B tests and experiments to drive measurable improvements
- Optimize performance and Core Web Vitals (LCP, CLS, INP)
- Improve SEO performance (rendering strategy, structured data, crawlability, indexing)
- Manage and tune CDN, caching, and edge delivery (e.g., Cloudflare, Engine)
- Work on marketing surfaces (e.g., WordPress, landing pages) to increase organic traffic and conversion
- Diagnose issues across SSR/prerendering, caching, and bot vs user behavior
- Own and ship end-to-end growth features across frontend (Vue SPA), backend APIs(PHP Laravel), and infrastructure
- Integrate external services (analytics, AI, payments) where needed
- Debug and resolve production issues across frontend, backend, and infrastructure
- Continuously improve CI/CD, observability, and performance efficiency
Required Qualifications
- 5+ years building production web applications
- Strong full-stack fundamentals (frontend + backend)
- Experience with:
- Frontend: Vue (or similar SPA frameworks)
- Backend: Laravel (or similar)
- Database: MySQL (or relational databases)
- Experience with SEO, performance optimization, or growth engineering
- Experience running or supporting A/B testing / experimentation
- Experience with CDN, caching, and browser performance optimization
- Experience with Docker / containerized environments
- Proven ability to make sound technical trade-offs
- Strong product mindset - focused on user and business outcomes
Preferred Qualifications
- Experience working on high-traffic SEO pages (100k+ monthly visits)
- WordPress (custom plugins, performance optimization)
- Experience with Elasticsearch (or similar search systems)
- Experience with analytics tools (e.g., PostHog)
- Experience modernizing or migrating legacy systems
- Experience working with VPAT (Voluntary Product Accessibility Template) or accessibility compliance documentation
What Success Looks Like
- You consistently ship measurable growth improvements
- You identify and fix conversion leaks and performance bottlenecks
- You design experiments and learn quickly from data
- You improve systems while moving fast
- You turn ambiguous growth problems into shipped solutions
- Identify bottlenecks in how we build and ship, and implement fixes that improve velocity and reliability.
