📋 Description

• Build and ship HTML5 playable ads using frameworks like Pixi.js, Phaser, Three.js, or custom WebGL solutions. • Optimize games for strict ad platform constraints, including file size limits, load time requirements, sandbox restrictions, and clickthrough behavior. • Ensure high performance across mobile browsers (iOS Safari, Android Chrome). • Architect reusable patterns and lightweight systems for rapid playable ad iteration. • Collaborate with design and product teams to translate concepts into high-converting interactive experiences. • Implement analytics and event tracking to measure engagement and conversion performance. • Debug and resolve issues related to rendering (Canvas/WebGL), input/touch handling, device compatibility, and performance bottlenecks. • Iterate quickly on builds based on performance data and creative feedback. • Integrate playable ads with ad network SDKs and platform requirements (Meta, Google, TikTok, Unity, etc.). • Maintain a high bar for polish, responsiveness, and user experience in short-session gameplay.

🎯 Requirements

• 5+ years of experience in software engineering, with a focus on web-based games or interactive ad units. • Deep proficiency in JavaScript/TypeScript and modern web game frameworks (Pixi.js, Phaser, Three.js). • Strong understanding of mobile browser performance constraints, memory management and optimization, and responsive layouts across devices. • Experience working within ad network specifications and limitations. • Proven ability to optimize for load time, file size, and runtime performance. • Experience integrating analytics or tracking systems to evaluate ad performance. • Strong debugging skills across browsers and devices. • Ability to move quickly and iterate in a fast-paced, test-and-learn environment. • Clear communication and ownership mindset — you can take a playable from concept to shipped product.
