Keep a friction log and read a sales book - product ownership with Joyce Er
Become an Epic Product EngineerShow Notes
If execution got cheap and you still wait for someone to tell you what to build, this episode is for you. Kent talks with Joyce Er about five years owning features on VS Code, the jump to product at Cerebras, and why trust is the metric that tells you the work is working.
They cover daily stand-ups that roast your feature in public, friction logs as taste practice, dogfooding when you cannot be the user, qualifying customers instead of taking every check, and why a sales book belongs on a product engineer's shelf.

Joyce Er spent five years as a software engineer on VS Code at Microsoft, with a front-row seat to GitHub Copilot and the shift from typing code to owning the why. About a year before this conversation she moved into product at Cerebras, the company behind dinner-plate wafer-scale chips for ultra-fast AI inference. The views in this episode are her own.
A major theme is ownership. On VS Code, every engineer owned the end-to-end definition of what shipped, not just the implementation. That only works with trust, dogfooding, and rituals that force you to defend the experience. Joyce describes a daily stand-up where you get five minutes to walk the feature, then the team roasts padding, consistency, and whether it belongs in the product. The lighter version is a bug bash. If people inside the company will not use the feature, that is a signal.
They also talk about how you grow judgment when nobody assigns the work. Joyce's first practice is a friction log: five minutes at the end of the day listing paper cuts in any software you used. Her more controversial homework is to read a sales book - she recommends The Qualified Sales Leader - so you understand how business value actually closes, especially when the product is not a credit-card checkout. Trust, she says, is the end-to-end metric: if customers and teammates trust you, you are doing the job.
Homework: keep a daily friction log, and read a book about sales.
Homework
Spend five minutes at the end of each day writing a friction log of paper cuts in software you used. Read a sales book - Joyce recommends The Qualified Sales Leader - and notice how value gets sold at your company. Use those notes the next time you decide what is worth building.

If you only get asked about feasibility, this episode is for you. Kent talks with Sam Julien - Director of Product at CopilotKit, author of Agentic GraphRAG - about moving past ticket-taking, collaborative product-engineering dialogue, and frameworks that help you push back with vocabulary. They cover leverage / neutral / overhead triage, Kagan's four big risks, communicating intent with AI agents, and why engineers need product models even when they have a PM.
If you ship features and never hear what users actually said, this episode is for you. Kent talks with Ben Vinegar - co-founder of Modem, formerly founding engineer and VPE at Sentry - about aggregating feedback, eliminating adoption barriers, and keeping human judgment in the loop as AI speeds up shipping. They cover FreshBooks-era product engineering, Modem's approach to capturing feedback across Slack, Discord, GitHub, and support tools, and why five real conversations beat a median LLM opinion.
If your backlog is full of tickets and zero customer contact, this episode is for you. Kent talks with Teresa Torres - product discovery coach, author of Continuous Discovery Habits, and host of Just Now Possible - about why engineers belong in discovery, what "just now possible" really means, and how curiosity beats solution advocacy. They cover opportunity solution trees, confirmation bias in decision-making, the Mom Test trap of pitching your solution, and homework that starts with one real conversation (or observing one).
If you still build for an audience of one and get defensive when users "use it wrong," this episode is for you. Kent talks with Mark Techson - staff developer relations engineer on Angular at Google - about empathy as a career differentiator, listening without defense, and why knowing what to build still beats vibe-coding forever. They cover internal tools as real products, a fitness-app failure that forced better questions, Google Developer Experts as a feedback loop, durable expertise in the AI era, and why attention is the scarce resource when anyone can ship. Mark Techson (legal name Mark Thompson) has spent about twenty years building software - teaching, senior engineering roles, a fitness startup, American Express fraud tooling, healthcare exchange apps, and now staff DevRel on Angular at Google. The views in this episode are his own; he notes he works for a major frontier-model provider. The through-line is empathy. Mark's number-one product-engineering skill is putting yourself in the end user's seat before you ship. Engineers who only implement tickets miss the concert of perspectives PMs, EMs, and builders bring when everyone aims at the best user experience. He compares great teams to a film set where talent still suggests a shoulder turn that makes the scene land. Listening without defense is the mechanism. Feedback means either you built it wrong or they cannot see how it works - both are actionable. Mark's hard lesson was a fitness app he built for himself: even his wife chose another app. Surveys flipped his assumption from "customize everything" to "just tell me what to do." At Google he leans on Angular GDEs and a simple reply to angry comments: tell me more. They also talk AI. Expertise is not going out of style - Mark uses a guitar-tuner analogy: auto-tune does not erase your ear. Knowing what to build, who to build for, and how to orchestrate agents matters more as code gets cheaper. Kent adds that human attention stays finite even if tokens get cheap. Mark closes against the "you're left behind" narrative: you do not have to live on the bleeding edge, but ignoring AI is the only wrong move. Homework: write a prompt for the first basic version of a product you have been postponing, run it in any AI tool, and notice what you failed to specify. Homework Pick a product idea you have postponed for lack of time or skill. Write a prompt that describes only the first basic version - not the million-dollar finished product. Run that prompt in any AI coding tool, then list what was missing from your prompt and iterate toward that first version.

If you ship a feature and never click through it yourself, this episode is for you.
