I did some modifications, otherwise LGTM!

About the styles of your components (see d39bd30):

• Use the gap property instead of margins whenever possible : it helps decrease code size and enforce consistency
• You tend to add unneeded (unstyled) <View> components
• You put a margin in the container style of the JobOfferItem component : avoid enforcing stylistic choices at the item level - here, you should have put this margin at also better, because what you really wanted was margins on the entire content of the page)
• Don't forget to add a <ScrollView> at the page level to be able to scroll - especially if you're rendering a list
