Ask HN: How to get a job as Gameplay Programmer?

I’m an experienced software dev - 8 years building apps and websites. I currently hold a Sr Software Engineer position at a startup, and write rails/js full time. For the last 6 months, I’ve been building and learning gameplay programming. What can I do to make the transition into new role and highlight my past software experience?

I think my knowledge of software patterns (GoF) and deep full stack experience gives me a unique approach to game dev. I also have 3 AWS certs, if that matters. I’m very comfortable in UNIX and any c derivative language.
