Job description

Position Summary

We are seeking a Senior Backend Developer who treats code as a craft and database performance as a science. You will be the architect of our "Internal Engine"—managing high-concurrency PHP applications, optimizing MySQL architectures on AWS RDS, and maintaining a containerized environment using Docker on Ubuntu 24.04.

This role requires a shift from a product-only mindset to a service-oriented delivery model, where building the "best version" meets "client-driven deadlines."

Technical Requirements (The Core Stack)

• Backend & Clean Code: Mastery of PHP 8.x. Deep knowledge of SOLID, DRY, and Design Patterns to ensure 500+ APIs remain maintainable and scalable.
• DB Architecture & Optimization: Advanced MySQL expertise. Optimize slow queries using EXPLAIN plans and advanced indexing. Design normalized schemas for massive datasets (e.g., 37-column customer profiles). Write atomic stored procedures to prevent race conditions during high-volume promotional schemes.

DevOps & Infrastructure

• Docker: Proficiency in containerizing microservices and managing docker-compose.
• Ubuntu OS: Expert-level command-line skills (SSH, CRON, and shell scripting).
• Automation: Hands‑on experience with n8n or similar workflow engines to "gatekeep" and automate complex data pipelines.
• Frontend: Proficiency in at least one modern framework (Vue.js, React, or Angular).
• CMS: Advanced WordPress development (Custom REST API endpoints and theme/plugin architecture).
• Version Control: Mastery of Git and Bitbucket (Branching strategies, conflict resolution, and code reviews).

Key Responsibilities

• Performance Engineering: Refactor legacy code and optimize database queries to reduce Server Occupancy and improve API response times.
• System Reliability: Manage the Sandbox (UAT) environment using Docker to ensure pre-production testing mirrors live environments perfectly.
• Data Integrity: Oversee the 5-hour Cron Job optimization to ensure multi-column data syncs are performant, fail-safe, and audited.
• Security & Connectivity: Manage OpenVPN tunnels, SSL/CA certificate deployments, and secure API handshakes.

What We Offer

Competitive Compensation

Role-appropriate compensation designed to attract and retain strong talent.

A workplace that values sustainable performance, practical support, and people-first decision-making.

Learning and Growth

Opportunities to build capability through real project exposure, cross-functional work, and expanding responsibility.

Flexibility Where Possible

We value outcome-driven work and support practical flexibility based on role and business needs.

Time to Recharge

A culture that respects personal time, sustainable work rhythms, and recovery from intense delivery cycles.

Shared Momentum

Regular team interactions, internal celebrations, and collective milestones that reinforce culture as the company grows.
