How do I affect the roadmap of my team and get some of my project ideas incorporated into it?

• Start building strong relationships ASAP, particularly with your product manager and tech leads. Influencing the roadmap is all about getting buy-in, so this is crucial, especially as you have neither extreme seniority or a very long tenure at the company.
• Dogfood the product as much as you can (i.e. use it yourself) to build a strong product intuition.
• Using competitor products is another way to build product intuition.
• Figure out how you can support your case to influence the roadmap with data. Everyone wants to be able to put their shiny thing onto the roadmap - What separates the successful ones from the not successful ones (on top of the social capital) is a strong suite of evidence. Mercari is a pretty big company with millions of active users, so I imagine you have some solid logging and analytics infrastructure there already.
