ATS Optimization Tips

Make sure your resume passes Applicant Tracking Systems used by US employers.

Use exact keywords from the job description, particularly in your skills section and work experience. ATS systems scan for specific terms to match your qualifications to the job requirements.
Format your resume with clear headings and bullet points. ATS systems often struggle to parse complex formatting, so keep it simple and easy to read.
Include a dedicated skills section that lists both hard and soft skills. This allows the ATS to quickly identify your key qualifications.
Quantify your accomplishments whenever possible using metrics and numbers. This provides concrete evidence of your impact in previous roles.
Use a standard font like Arial or Times New Roman, and a font size between 10 and 12 points. Avoid using unusual fonts or decorative elements that may not be recognized by ATS.
Save your resume as a .docx or .pdf file. These formats are generally compatible with most ATS systems.
Ensure your contact information is clearly visible and accurate. ATS systems need to be able to extract this information to contact you.
Tailor your resume to each specific job application. Highlight the skills and experience that are most relevant to the role and the company's technology stack. Many Principal Tech Systems Administrator positions require experience with specific tools and technologies, like ServiceNow, SolarWinds, or particular cloud platforms.

Common Resume Mistakes to Avoid

Don't make these errors that get resumes rejected.

1
Failing to quantify accomplishments. Instead of saying 'Improved system performance,' say 'Improved system performance by 20% through automation scripting.'
2
Not tailoring the resume to the specific job description. Generic resumes get overlooked; highlight relevant experience for each application.
3
Omitting key technical skills. Ensure you list expertise with relevant tools like Kubernetes, Docker, Ansible, Terraform, and specific cloud platforms.
4
Neglecting to showcase leadership experience. As a Principal, you're expected to lead projects and mentor others; provide concrete examples.
5
Using outdated or irrelevant information. Focus on your most recent and relevant experience, and remove outdated skills or technologies.
6
Ignoring formatting errors. Typos, grammatical errors, and inconsistent formatting can make your resume look unprofessional.
7
Not highlighting experience with security best practices. Emphasize your knowledge of security protocols, vulnerability management, and compliance standards.
8
Being too verbose. Hiring managers appreciate concise and impactful descriptions. Cut unnecessary words and focus on the most important details.
