What engineering work involves at an early-stage startup
You own whole parts of the product rather than one service inside a large system. Expect to write the code, deploy it, and get paged when it breaks. Reviews are quick and the codebase is small, so a decision made on Tuesday can ship on Thursday.
Experience level
Open roles by the experience the posting asks for.
