About the Role
We are seeking a highly experienced Web Developer with deep expertise in building, scaling, and optimizing phone directory-style websites. This is not a basic web development role. We are looking for someone who understands large datasets, search functionality, SEO at scale, and user behavior within directory-driven platforms.
If you have worked on sites involving phone lookups, business directories, reverse search tools, or large database-driven websites, this role is for you.
Key Responsibilities
Design, develop, and maintain large-scale directory-based websites
Build and optimize search functionality (phone number lookup, filtering, indexing)
Structure and manage large datasets (millions of records if needed)
Implement fast, scalable database architecture
Optimize site performance (speed, indexing, crawlability)
Develop SEO-friendly URL structures and internal linking systems
Work with structured data (schema markup) for enhanced search visibility
Improve user experience and conversion on high-traffic pages
Troubleshoot and resolve performance bottlenecks
Collaborate with marketing and SEO teams on growth strategies
Required Experience

Phone directory sites
Reverse phone lookup tools
Business listing or data-driven websites
Strong understanding of:
Database design (MySQL, PostgreSQL, or similar)
Backend development (PHP, Python, Node.js, etc.)
Frontend technologies (HTML, CSS, JavaScript)
Experience handling large-scale data and indexing
Knowledge of SEO for programmatic pages
Experience with APIs, scraping, or data ingestion pipelines (a big plus)
Technical Skills
Backend: PHP, Python, Node.js (at least one strongly preferred)
Frontend: JavaScript, modern frameworks a plus
Databases: MySQL, PostgreSQL, or NoSQL solutions
Familiarity with cloud hosting (AWS, DigitalOcean, etc.)
Experience with caching systems (Redis, CDN, etc.)
What We’re Looking For
Someone who has real-world experience with directory-style sites, not just standard websites
Strong problem solver who can handle scale and complexity
Detail-oriented and performance-focused
Able to work independently and deliver results
Bonus (Nice to Have)
Experience with web scraping or data aggregation
Knowledge of compliance considerations around phone data
Experience with high-traffic sites (100K+ monthly visitors)
Familiarity with tools like Ahrefs, SEMrush, or Google Search Console
