Question 2

What is a context engineer?

Accepted Answer

Someone who designs what a language model sees: the retrieval, memory, tool results and instructions that fill its context window. The term spread in mid 2025 as the successor to prompt engineering.

Question 4

What is the difference between an AI engineer and an ML engineer?

Accepted Answer

An ML engineer trains, ships and maintains machine learning models. An AI engineer mostly builds products on top of models someone else trained, calling them through APIs, with retrieval, agents and evals. In Hacker News Who is hiring threads AI engineer has been mentioned more often than ML engineer every month since December 2025.

Question 5

Where do the numbers come from?

Accepted Answer

Two public sources. Every monthly Hacker News "Ask HN: Who is hiring?" thread since April 2011, read through the free Algolia API: a title's share is the percent of that month's postings that mention it. And the public job boards (Greenhouse, Ashby, Lever) of a growing set of data, AI and tech employers (found through the fru.dev company registry and links in Who is hiring posts), read weekly: open roles by title, and salary ranges where a posting states one.

Question 6

How are salaries worked out?

Accepted Answer

Only from postings that state a pay range themselves (many US postings must). The median is the middle of the midpoints of those ranges, in US dollars per year. Postings without a range are left out, so a title with few stated ranges has a rough median.

Question 7

Something is wrong or missing. How do I fix it?

Accepted Answer

Every title and company page has Suggest a correction, and the listing pages have Suggest a missing title. Each suggestion is checked before anything changes.
