As an AIX Administrator, your resume should prioritize clarity and technical precision. Use a reverse-chronological layout to showcase your system management experience. Stick to one page if you have fewer than 10 years of experience; two pages are okay for seasoned professionals with extensive relevant history.
Choose simple, ATS-friendly fonts like Arial or Calibri at 10-12pt. Avoid fancy fonts or multiple font types. Use 1.15x line spacing with 0.5-inch margins to ensure readability. Break your resume into clear sections: Experience, Technical Skills, and Certifications work best for AIX roles.
A common mistake is using column-based layouts. ATS systems often misread these, causing your resume to vanish. Also, avoid graphics or color unless the job explicitly asks for it. Keep your contact info in a simple header. For AIX Admins, bullet points with specific tasks (e.g., "Managed LPAR creation") beat vague statements like "Handled system duties".
