Throughout the development of Metroid Prime 4, Retro Studios has sought to hire talented developers from across the game industry to work on engineering the gameplay, concepting cutscenes, write the story and fulfill other responsibilities. The Nintendo careers page has been updated with new positions. In addition to these, Retro is currently still seeking more Concept Artists and Contract Environment and Lighting Artists. The new positions added are as follows:

• IT Engineer (Level 1 and 2, Contract)
• Level 3 Environment Designer
• Level 2 System Designer

As of December 2020, Retro was looking for a Boss/AI Designer and a Lead Technology Engineer. These jobs have disappeared from the careers page, suggesting they have been filled. As always, we will keep you updated about any new hires at Retro while we await a true unveiling of Metroid Prime 4.
