Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Lead the design and implementation of scalable, production-grade AI/ML and decision automation systems for Candy Crush Saga. Drive technical direction through hands-on coding, architecture design, and mentoring senior engineers to unify fragmented AI approaches.
Requires deep expertise in shipping production AI/ML systems, specifically in personalization and causal inference. Candidates must demonstrate proven technical leadership and the ability to influence architectural direction across complex, cross-functional environments.
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 Automation team 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 at scale. This 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.
What You’ll Do
Influence technical direction across Candy Crush Saga in AI/ML and decisioning through credibility, clarity, and delivery
Stay hands-on through meaningful production coding, technical prototyping, and implementation work on critical paths
Set a high bar for production AI/ML engineering, including reliability, observability, maintainability, and quality of execution
Mentor senior engineers and raise the standard of technical judgment, design quality, and cross-team collaboration
Lead the shared architecture for AI/ML and automated decisioning systems used across multiple components in Candy Crush Saga
Help unify fragmented approaches into reusable technical foundations that improve consistency, speed, and scalability
Partner with product and game teams to turn high-value opportunities into reusable capabilities rather than one-off solutions
What You Bring
Deep AI/ML Expertise
Deep experience building and shipping production AI/ML systems with meaningful business impact
Strong applied expertise in areas such as personalization and causal inference
Track record of connecting AI/ML methodology with real production guardrails, constraints and operational use
Technical Leadership
Proven ability to influence technical direction across teams through credibility, clarity, and execution
Experience defining shared patterns, technical standards, or architectural direction in complex environments
Ability to lead senior-level technical discussions with substance and precision
Communication and Collaboration
Excellent communication skills, with the ability to explain complex technical ideas clearly to both technical and non-technical audiences
Proven ability to influence across departments and align teams around shared technical direction
Strong mentoring capability, especially with senior engineers and technical leaders
Comfortable representing technical work in high-visibility forums, internally and externally
Product and Cross-Functional Collaboration
Able to shape product bets through technical insight and co-create reusable capabilities with cross-functional partners
Effective working across engineering, analytics, product, and platform teams
Strong judgment in translating business goals into scalable technical systems
Nice to Have
Experience with large-scale experimentation platforms, personalization systems, or decisioning infrastructure
Familiarity with game technology, player-facing optimization, or content adaptation systems
Experience reducing fragmented or bespoke ML workflows into shared technical foundations

Stockholm, Barcelona and London
