About Us

We're building cutting-edge AI technology that powers sophisticated ad analysis and generation pipelines for elite global gaming companies.

We don't follow trends; we set them. Our data infrastructure supports technology that generates millions of dollars in value for our customers, processing billions of gameplay and ad-performance signals in real-time.

The Role

We're seeking an exceptional Senior Data Engineer to join our fast-growing team in Ho Chi Minh City. This is not a role for the average analyst—we're looking exclusively for extraordinary data talent who can compete with the best data engineers and analysts at top-tier companies globally.

As our first data engineer, you'll set the foundation for data-driven decision making across our entire organization. You'll design and implement sophisticated analytics infrastructure that processes terabytes of gaming and advertising data, directly influencing product decisions that impact hundreds of millions of players.

Core Responsibilities

Define company-wide data strategy: Establish north-star metrics, experimentation frameworks, and analytics standards that will scale from startup to enterprise
Build world-class data infrastructure: Design and implement pipelines processing billions of ad performance signals and gameplay events with exceptional reliability and speed
Drive multi-million dollar decisions: Surface insights from massive datasets that directly influence product roadmap and customer strategy
Own end-to-end analytics: From instrumentation design to executive dashboard delivery, ensuring data quality that leadership can bet the company on
Lead advanced experimentation: Design and execute sophisticated A/B tests and multivariate experiments that optimize our AI-driven platform
Establish data excellence standards: Create governance, quality, and best practices that will serve as the foundation for a world-class data team
Champion data-informed culture: Influence technical and business decisions through exceptional analysis and clear communication

History of driving significant business impact through data insights and experimentation
Expert-level understanding of statistical methods, A/B testing, and causal inference

Essential Qualities

Exceptional problem-solving ability: You consistently find insights others miss and solve complex analytical challenges independently
Product intuition: You naturally think like a product leader and can translate business questions into analytical frameworks
Technical excellence: You write clean, maintainable code and build systems that other engineers admire
Intellectual curiosity: You stay ahead of data trends and continuously expand your analytical toolkit
High ownership: You take full responsibility for data quality and business impact, not just deliverables
