Asked by a working FDE. Palantir split the role in two: Echo, closer to the customer and the subject matter, and Delta, closer to the code.
Nominal has mission ops, mission development, and a growing sales team. Mission ops are deeply technical but not always coders: often former mechanical or electrical engineers, some who designed engines, though increasingly they write code anyway. The reasoning is that understanding an engineer's workflow is far easier if you have lived it. He calls this a loose descendant of Palantir's Echo role, noting Echoes often lacked the subject background and were instead capable generalists, frequently from consulting.
It's really helpful if you have that background being part of that organization before, and that's why we have the mission ops role.
He was an Echo intern and then a Delta, and thinks AI collapses the split. The division existed because writing code was expensive enough to need dedicated coders while others owned the relationship. If code gets dramatically cheaper, one person can hold the whole picture, which he calls radical ownership.
If you can dramatically reduce the cost of the production of code, then perhaps you can have this radical ownership where one person can actually hold all of that context in their head.
Why he thinks that is better: the same person knows what is genuinely hard and what is easy, so decisions about what is worth building are not made by someone who cannot judge the cost. He is candid that it depends on finding people with that range.
They're not just a pure non-technical person making those value decisions.
He came from traditional consulting and disliked how many narrow roles it had, so OpenAI began with engineers only. They quickly found large accounts needed Echo-style people to carry the account work, so that role came back.
When we started the team there was only FDEs, and we realized very quickly that we really needed the echoes to take up a lot of the work around the account.
Now they are adding genuine industry experts, such as chip verification engineers and working scientists, because harder problems mean writing good tasks and tests inside a specialism. There are deliberately few, on the bet that the generalists learn from them.
When we go up the stack in chip design, we really need to know how to design a chip.
