Anthropic engineering leader reveals how AI drove an eightfold increase in code output
Building the most AI-pilled engineering team in the world | Fiona Fung (Manager of the Claude Code and Cowork Teams)
As AI tools automate manual coding, engineering leadership must evolve to manage massive code volumes, asynchronous agent workflows, and shifting developer roles.
- 1AI tools have driven an eightfold increase in code output, forcing engineering teams to adopt asynchronous workflows and automated agent routines.
- 2Hiring priorities are shifting toward creative builders with strong product sense and deep systems experts who can orchestrate complex architectures.
- 3Traditional engineering metrics like lines of code are obsolete, replaced by proactive quality monitoring and developer frustration tracking.

Fiona Fung contrasts her early days shipping software on physical CDs at IBM with today's real-time, agent-driven engineering workflows.
The brief
Anthropic engineering leader Fiona Fung manages the teams behind Claude Code and Claude Cowork, experiencing firsthand a world where software engineering output has increased eightfold because coding is no longer the bottleneck.
This massive code spike shifts the developer role from manual syntax writing to high-level system orchestration, requiring engineers to deploy automated routines that coordinate fleets of autonomous AI agents on their behalf.
To manage this rapid output without losing control, Fung relies on proactive quality monitoring, tracking critical errors via specific thresholds and keeping developer frustration low through pairwise programming lunches.
Fung reflects on her 25-year career, comparing the slow feedback loops of shipping database software on physical CDs at IBM to the real-time, agent-driven workflows she manages today.
As traditional metrics like lines of code become obsolete, the most successful engineering teams will prioritize creative builders with strong product sense over developers who merely write code.
