1. 1Setting multi-year strategy
2. 2Org design and operating models
3. 3Coaching senior managers and staff peers
4. 4Choosing what NOT to do
5. 5Long-horizon trade-offs

1. Match the level of scope: Show direction-setting. Bullets should reference long-horizon strategy, function-wide standards, and coaching of senior peers.
2. Use principal-appropriate verbs: Pioneered, Set, Shaped, Championed, Transformed, Steered. Avoid generic verbs like "helped" and "worked on" — they read as low-ownership.
3. Quantify outcomes: Numbers, percentages, and dollars beat adjectives. "Reduced churn 22%" is more persuasive than "significantly improved retention".
4. Match Process Optimization, Lean Manufacturing, Six Sigma keywords: These are the ATS-critical terms for Process Engineer roles. Make sure they appear in both your skills section and at least one bullet point.
5. Tailor to the job description: Run your final resume through the ATS checker against the specific JD. Aim for 70%+ keyword match before submitting.
