Advice for New Principal Tech ICs (i.e., Notes to Myself)
A practical guide for engineers promoted to principal-level IC roles, covering mindset shifts from coding to technical vision and cross-org influence.
Key Points
- Principal ICs shift from pure coding to technical vision, design feedback, and business context
- Different principals have different styles - find your strength rather than imitating
- Stay hands-on but focus more on connecting teams and discovering new problems

From Writing Code to Setting Direction: A Survival Guide for Principal Engineers
Eugene Yan wrote this note to himself after being promoted to Principal Engineer (L7+) at Amazon. While a personal reflection, it serves as an invaluable "survival guide" for any tech professional transitioning from Senior Engineer to Staff/Principal level.
The Biggest Shift in Mindset
Yan summarizes the most critical cognitive shift: Your core job from before has now become a "side hustle."
This isn't to say you should stop writing code altogether, but rather that writing code is no longer your biggest contribution to the team. Your new responsibilities include:
- Defining the technical vision and direction
- Providing design review feedback
- Offering business, product, and technical context
- Identifying new problems and connecting the work of different teams
Even if you're still spending 80% of your time coding, that 20% dedicated to strategic work is where you'll truly make an impact.
There's No Standard Template for a Principal Engineer
Yan observes that successful Principal Engineers come in different "flavors":
- Some delve deep into a specific domain, becoming technical authorities in that area.
- Some excel at cross-functional influence, coordinating multiple teams towards a common goal.
- Some are technical trailblazers, leading by example and demonstrating "how things should be done."
- Some are adept at untangling complexity, providing clarity and direction for the team.
The key is not to imitate anyone, but to identify your own strengths and amplify them.
Maintain a "Hands-On" Baseline
"Any Principal Engineer who stops being hands-on for too long is digging their own grave."
Writing code is crucial for maintaining technical intuition—without getting your hands dirty, how can you judge whether a technical solution is elegant or a disaster waiting to happen? But being hands-on doesn't mean doing everything yourself; it means staying sensitive to technical details through practical engagement.
Implications for Tech Professionals
This promotion path is mirrored in many companies. The core challenge remains the same: shifting from "I can get it done" to "I can ensure the team is heading in the right direction." Many talented engineers get stuck at this point, not because of technical shortcomings, but because their role perception hasn't caught up.
Yan's notes provide an excellent framework for reflection: Are you spending your time in the "right" places?
