PHP Jobs Requiring Experimental Design

PHP developers with skills in experimental design are crucial for data-driven organizations that rely on testing to guide product development. This specialization involves implementing the technical foundation for A/B testing, multivariate testing, and feature flagging. The goal is to create systems that allow teams to measure the impact of changes on user behavior and key business metrics with statistical confidence.

Technical Implementation of A/B Testing

In this role, a developer's responsibilities include building or integrating logic that segments users into different groups (control and variant). They ensure that each group is served a different version of a feature, button, or user flow. They are also tasked with implementing robust event tracking to collect data on user interactions and conversions, which is then sent to an analytics platform for analysis.

Core Skills and Competencies

A strong foundation in both backend development and data principles is necessary for success in roles focused on experimental design.

• Experience building or integrating feature flagging systems.
• Knowledge of third-party A/B testing tools (e.g., Optimizely, VWO) and their APIs.
• Proficiency in implementing event tracking and integrating with analytics services.
• A foundational understanding of statistical concepts like significance and sample size.
• Ability to write clean, performant code that doesn't negatively impact user experience.
