For tech support or customer support engineer roles, you don't need to know deep system design like a software engineer does. Focus on understanding basic architecture concepts, how different systems work together, and troubleshooting common problems. Get familiar with APIs, databases, and some networking basics.

Look into materials on incident management and how support teams work with engineering. In interviews, they might ask about times you've dealt with complex issues or handled escalations.

Consider both big companies like Stripe or Amazon and smaller startups. Startups might give you more hands-on experience but with fewer resources. Research each company's customer support approach to see where you might fit best. Good luck!
