- 04.1Software developmentBuilding the working product across the stack, from interface to server, and keeping the code organized as it grows.
- 04.2Software architectureThe large-scale structure of a system and the tradeoffs behind it. Good architecture keeps future changes cheap.
- 04.3Data engineeringDesigning, storing and moving data so it stays correct, fast to query and safe to change.
- 04.4Engineering qualityPractices that keep software correct as it changes: tests, reviews, debugging and steady improvement of the code.
- 04.5Performance engineeringMaking the product fast where users notice, and keeping it fast as it grows.
- 04.6Security and privacy engineeringBuilding products that protect users and their data, and knowing when to call in a specialist.
- 04.7AI-native engineeringBuilding product features on top of language models and agents, where behavior is probabilistic and must be measured rather than assumed.
- 04.8Developer experienceThe tools and workflows that make engineers productive, for your own team or for the developers who use your product.
About Engineering
04Engineering is the home ground of most product engineers: turning a decision into software that works, stays correct as it changes, and can be operated safely. The product angle changes the emphasis. Speed of learning matters as much as elegance, and the best technical choice is the one that serves the product at its current stage, including AI features that need new ways of testing.
What a product engineer should be able to do here
Build the complete technical solution, reason about architecture, verify its behavior, and maintain quality without requiring detailed implementation instructions.
