Designing your principal software engineer resume format to catch recruiters' eyes

Your principal software engineer resume will be assessed on a couple of criteria, one of which is the actual presentation.

Is your resume legible and organized? Does it follow a smooth flow?

Or have you presented recruiters with a chaotic document that includes everything you've ever done in your career?

Unless specified otherwise, there are four best practices to help maintain your resume format consistency.

  • The top one third of your principal software engineer resume should definitely include a header, so that recruiters can easily contact you and scan your professional portfolio (or LinkedIn profile).
  • Within the experience section, list your most recent (and relevant) role first, followed up with the rest of your career history in a reverse-chronological resume format .
  • Always submit your resume as a PDF file to sustain its layout. There are some rare exceptions where companies may ask you to forward your resume in Word or another format.
  • If you are applying for a more senior role and have over a decade of applicable work experience (that will impress recruiters), then your principal software engineer resume can be two pages long. Otherwise, your resume shouldn't be longer than a single page.

  • Don't go too far back in your experience - recruiters will only care what you did a decade ago if it's really important for the principal software engineer role;
  • Each bullet you include should say what you did, followed by the skills you used and the actual end result of your efforts;
  • Quantify each of your achievements with numbers and possibly the overall effect it had on the organization;
  • Highlight transferrable skills - or personal skills you've attained thanks to past jobs - that could be applicable within your potential workplace. This would showcase your unique value as a professional.
