- Match System Architecture, Technical Leadership, Cross-org Influence keywords: These are the ATS-critical terms for Principal Engineer roles. Make sure they appear in both your skills section and at least one bullet point.
- Tailor to the job description: Run your final resume through the ATS checker against the specific JD. Aim for 70%+ keyword match before submitting.
