Job Description:

Senior Principal AI/ML Engineer – Decision Automation Candy Crush Saga | King Are you motivated by building the shared decisioning foundations for how a live game learns, experiments, and adapts at scale?

Join King as a Senior Principal AI/ML Engineer in the Decision Automationteam for Candy Crush Saga. In this role, you will help turn fragmented AI/ML and decisioning approaches into scalable, production-grade systems that support faster experimentation, safer adaptation, and more coherent player experiences across the game.

This is a hands-on senior technical leadership role. You will shape direction through architecture, code, prototyping, design reviews, and deep technical judgment. We are not looking for a strategy-only leader. We are looking for someone who can build, simplify, and connect complex systems across team boundaries.

The Role You’ll join the Decision Automation team within Candy Crush Saga: a cross-functional AI/ML team working closely with product, analytics, engineering, game teams, and central platform partners to enable faster, smarter, and more player-centric decisions across the game.

Our mission is to accelerate Candy’s learning loop by automating insight generation, experimentation, and adaptation s role is central to helping define and build the shared architecture needed to make decision automation more scalable, reliable, and reusable across Candy.

The team works across areas such as:

Causal inference and simulation capabilities usable by product teams

Generalized automated decisioning systems across multiple game features

Orchestration across ML systems to reduce conflicting treatments and coordination overhead

With hundreds of millions of players, the systems you help shape will operate at significant scale and influence core player-facing decisions across Candy Crush Saga.
