Sally and Joël join forces to discuss the different ways to interpret the role of a ‘principle’ or ‘staff’ engineer, and the handwaving around what those titles mean in terms of the gradation. Whilst Joël dives into career progression within the industry, what a staff engineer does and the different archetypes within it, Sally talks about the importance of having principle engineers in the room during AI discussions, and her previous positive experiences working with principle engineers. — Joel used the Staff Archetypes page from staffeng.com during this episode’s discussion.
