Principal Editor Framework Programmer


Apply now

Guerrilla is looking for a Principal Editor Framework Programmer to help architect and implement the next iteration of Decima Engine's Editor! This role requires strong programming skills, solid architectural design experience for building frameworks and a passion for good user experiences.

Who Are We

Decima Engine

At Guerrilla, we’re passionate about creating cutting-edge technology tailored to the needs of our games and our partners. That’s why we built Decima: an award-winning, industry-leading engine designed from the ground up. Decima pushes modern hardware to its limits, delivering best-in-class graphics and performance. It also empowers teams with artist- and designer-friendly workflows, robust production planning tools, and advanced debuggers for programmers. We believe that the tools a studio uses are just as important as the games they create—and with Decima, we’re setting the stage for innovation and creativity.

The Decima Editor is used in-house and externally by hundreds of artists and designers to develop extraordinary open world games! It's a comprehensive native desktop application encompassing a 3D and 2D world editor, asset browser, node-based editors, a sequencer timeline, review tools, localization, and sound design pipelines.

Tools Team

The Tools Team is one of Guerrilla's Decima Engine teams and is the owner of the Decima Editor and its underlying technology stack. We tackle a wide variety of challenges to make the Engine easier and more effective to use, both for end users and tool developers throughout Guerrilla. To achieve this we design, develop, and maintain the foundation of the Decima Editor experience. We’ve built a comprehensive set of re-usable Editor Components and Editor Services. These components, together with our UI Framework and Editor Viewport, are commonly referred to as the Tools Framework.

We are proud of creating an innovative, powerful toolset and of supporting other teams of programmers, artists, and designers to achieve their vision!

Tools Framework

The Tools Framework is built around a set of reusable visual components and a set of background services. It empowers other programming teams to develop tools within the Decima Editor to support their discipline, project or product needs. 

The framework provides a lightning fast Asset Browser to find content, an Asset Indexer which has complete in memory map of object relations allowing for quick navigation and reasoning about content structure, a Data Model as the memory representation of all loaded and modified content, a transaction based Undo/Redo service, a flexible Attribute Editor and many, many more controls, components and services.

The Decima Control Framework allows building UI components to visualize and manipulate data. Combined with our layout and docking systems it allows us to dynamically structure the Editor based on discipline or users preferences. Our Editor UI is fast, simple and pretty by clever usage of Signed Distance Fields and a Tile Based Renderer. 

The Decima Editor Viewport is a common control used to preview and edit content using our 3D runtime, an embedded out-of-process version of the game. Having the game logic as part of the viewport allows users to edit content and directly play without loading a separate instance. It supports live content updates directly in our Viewports, and quickly replaces complex content hierarchies via Game Sync. 

Tools Team Projects

The Tools team has a broad range of responsibilities. These can be designing and implementing entirely new workflows, improving current ones, or refactoring existing systems and frameworks, all to support making better games more easily. Some recent and upcoming examples include:

  • Creating freeform content deformation tools used in 3D Viewports to allow artists to quickly and easily tailor assets to the look and feel of a specific game.
  • Removing QT dependencies from our control framework to more tightly integrate it into our lowest level libraries to allow for tighter integration of our tools in our games and even remove platform boundaries when using our tools.
  • Re-envision the scriptwriting workflow from a cumbersome word and spreadsheet-based process into using a single integrated tool that integrates seamlessly with script, cinematic and localization workflows.
  • Architect the next iteration of Viewport integration to reduce dependencies on content loading and greatly improve content changes at world scale. 
  • Extending the feature set of terrain modifications, including paint tools, non-distructive procedural content generation and improved Gizmos in our World Editor.
  • Making documentation easier to read and write by implementing a WYSIWYG editor and responsive, full-featured in-engine documentation reader.

Q: I don't have any work examples. Can I still apply for a job?
A: It's essential that you can prove to us that you have the necessary skills for the job. Rushing into an application without supplying the required materials won't leave a good impression. In general, it's a good idea to put together an excellent portfolio before you start applying for jobs.  

Q: I have no experience in the games industry. Can I still get a job with you?
A: Games industry experience is certainly a bonus, but it's not always necessary. It's important to put together an excellent portfolio that demonstrates your skills and your understanding of the game development process.  

Q: I applied for a job with you, but I haven’t heard back. What happens now?
A: We aim to respond to all applications within three weeks. Due to the volume of requests, this sometimes takes a little longer. If you have not heard from us within three weeks, your application was most likely unsuccessful.  

Q: How can I arrange a job interview with you?
A: We receive so many applications that we are only able to arrange interviews with the most suitable candidates. It's important that your application stands out from the crowd. Go ahead, impress us!  

Q: I'm considering working at Guerrilla in the future. Is it possible for me to come for a tour of the studio?
A: Because of the confidential nature of the projects that we are working on, we cannot allow visitors into the studio. The most impressive job applicants will be invited for an interview, and will have an opportunity to visit some of the development areas.  

 

Q: I'm a university student looking for a company that can help me with a (master) thesis assignment. Can we arrange a meeting to look at the different possibilities?
A:We like to help out with university level assignments when we can! However, due to time constraints and deadlines this isn't always possible. Please send a brief e-mail outlining the aims of your assignment and what input you would need from us. We'll let you know if we are able to help you.  

Q: I'm a high school student and I have to do a school assignment on media and entertainment. Can I make an appointment for an interview with one of your employees to discuss this?
A: Due to the sheer number of requests we receive, we regret that we are unable to participate in interviews with school students.  

Q: I have a great idea for a game. How can I submit it to you?
A: All of our game concepts are developed by our internal designers, in conjunction with our publishers. It is company policy not to accept game concepts from third parties.  

Q: I'm still in school and I want to get a job in games in the future. What kind of education and skills do I need to achieve this goal? Can you provide me with information on the schools that teach this discipline?
A: The skills required to work in the games industry are very broad, as there are many areas in which you can work. In development there are roles in art, animation, programming, design, and project management. Other industry roles include sales, marketing, PR, and testing. The most important thing is to get an education in subjects that you enjoy and that you are good at. Your career adviser should be able to give you guidance as to which careers are suitable for an individual with your particular skills.
