## Description

King operates mobile games at a massive scale. With titles like Candy Crush, Candy Crush Soda Saga and Farm Heroes Saga, our code runs on hundreds of millions of devices across the world. We believe that the right tools in the right hands are key to our success as a company.
If you want to boost productivity for the teams creating entertainment for millions of players to enjoy on the go then this is the right job for you. In the role of Game Engine Developer, you'll be at the heart of our tech, evolving the cross-platform engine and toolchain that empowers hundreds of developers to build King's world-class casual games.
This role belongs to part of the Kingdom we call Shared Tech. The teams within Shared Tech work as B2B organizations working across all the technology that we use to power our live games, including data infrastructure, machine learning, payments infrastructure and the game engines themselves. The vision within Shared Tech is "We are the stage where King games love to perform".
You will be working in Shared Tech's Game Production organization, where we focus on game-changing tooling and infrastructure to enable our content creators to build features faster, easier and more reliably. This includes working across multiple teams to facilitate both architectural decisions and hands-on development to support smaller feature teams based on rolling needs.
You should have a broad range of knowledge and be able to context switch easily to provide active support across the whole team and beyond. The ability to see the project as a whole is crucial as you monitor the development in real- time to determine how we should support and assist the rest of the development team. You'll also play a key role in improving our feedback loop, making it easier for teams to adopt tools and for our team to learn what's working (or not). Strong communication and empathy for end users are essential.
King is a place where we build features in the open, collaboratively. We value diverse opinions and make sure every voice is heard. We offer you the freedom and opportunity to work on fulfilling tasks and to continue your journey as an expert tools developer.

Your role within the Kingdom
You will enjoy a creative, challenging and collaborative environment where your ideas will be every bit as valued as your programming expertise.
Some of your responsibilities include:

 + Develop the game engine, refine new and existing features, and design, implement, and maintain in-house tools embedded directly within our products.
 + Collaborate with various current and future users of our Game Engine, bridging various crafts within King with the intent to optimize, improve and discover workflows across games
 + Deliver high quality and well-structured code
 + Improve quality and performance inside our products landscape
 + Share knowledge and best practices with peers and game teams
 + Drive and support features adoption with stakeholders in the game teams across King
