Great news, good luck on the application.

This is how I apply for jobs ...

First, get a copy of the job description. Write an actual application, addressing each of the key capabilities in a paragraph each. Give examples from the work you currently do - mention that you're familiar with systems & tools, and any "well dones" or awards you've received, along with a reference to any KPIs you've met / exceeded.

I generally also write a cover letter, along the lines of "I'm good for this job because x y & z and look forward to discussing further" and then have my resume, then the application.

For referees, check with your supervisors or employment agency if they will let people call to check on you. Some companies have a policy of no external referees, but will allow personal referees (where you could mention they were your supervisor!!!)

Good luck!
