Philip Su has spent two decades at the highest levels of software engineering — Microsoft, Meta (where he reached Distinguished Engineer, IC9), OpenAI, and now building his own product solo with AI. In this episode, he makes a provocative case: the individual contributor role as we know it is over, code reviews are becoming a liability, and the best engineers are already managing AI agents instead of writing code themselves.
From Dirty Fuel to Clean Fuel — Philip’s Unusual Career Arc
“When I look at those employment opportunities, I feel like maybe one theme is moving from what people are calling dirty fuel into clean fuel — meaning, what sorts of things motivate you? Dirty fuel would be something like, my parents never complimented me and so now I’m going to drive and prove them wrong. Clean fuel would be, I’ve always loved computer science and I’m here to do it.”
Philip’s path through tech is anything but linear. He became a dev manager at Microsoft before 30, then spent the next decade comfortable but stagnating — until he interviewed at Google, Amazon, and Meta and received offers three levels below his Microsoft position. That fear drove him to Facebook in 2010, when it had just 500 employees and people were still saying Friendster would come back. He scaled the London engineering office from a dozen engineers to 500+, then stepped away entirely.
Depression led him to take a warehouse floor job at Amazon during Peak 2021 — 11-hour shifts, moving six tons of packages a day with his arms. He documented the experience in his Peak Salvation podcast. The lessons were sharp: incentives shape behavior (warehouse workers got raises based on tenure, not performance, which incentivized doing the minimum), changing machines that are already operating is brutally hard, and misplaced pride is dangerous. Workers on the floor laughed when robots failed. Philip’s takeaway was the opposite: “Do you think the corporate robot designers just gave up and went home? Or do you think V2 is coming and V3 is coming until finally it takes over your job?” He later joined OpenAI as an individual contributor before leaving to build Superphonic, an AI-powered podcast player.
No More Code Reviews: The Lights-Out Codebase
“I grew up in the 80s and 90s. Today, even Stockfish, free on your phone, can beat the world’s best chess masters. What if I proposed to you today that you should take that free software, and when you’re playing some other player, have a human chess master review every move, just to make sure the AI hasn’t made a mistake? I would think that was patently ridiculous.” Continue reading AI-Assisted Coding: Why a Distinguished Engineer Stopped Reading Code — Lights-Out Codebases and the End of the IC
