43 minutes Posted Apr 5, 2026 at 12:30 pm.
Alex is the product lead for Codex and Romain runs developer experience. They gave me a rare inside look at how the Codex team operates, including how they build products with Codex and how they ship without traditional specs and roadmaps. Alex also has some spicy takes on the future of PM and what actually matters when hiring.We talked about:
Live demo: Building a game in seconds with Codex Spark
"For specs, we write like 10 bullets and that's it"
"Our designers now write more code than eng 6 months ago"
"We plan short and long term, never medium term"
How Alex actually spends his day as Codex PM
The traditional career ladder no longer makes sense
