Get ready to apply

Built only from what this listing states. Tick as you go; the ticks stay on your phone and are not sent anywhere.

The application takes real work, by our reading.

1. What to get ready

CV or resumeOne or two pages. No CV yet? Our CV starter builds a plain one from your answers.
Cover or motivation letterShort, written for this one: why this, what you have done that fits.
Certificates or degree copiesScan or photograph them clearly, in good light, flat.

It also names something beyond these; read their words below.

In their words: “Canonical's online form asks for a resume (required) and a cover letter (optional). It also asks for required written answers about the cryptography or security certification products you have contributed to, plus your high school maths and language results with supporting evidence and your degree result.”

2. Dates

No closing date is stated.
Openings with no closing date can close once they have enough people, so sooner is safer. Our advice

The download is a small text file. You can read it later without data. It also lists each condition they set, so you can tick yourself against them. WhatsApp sends the same list to you, or to somebody helping you.

Tips for applying for a job

General advice from us, the same for every job. It is not what this organisation says; that is above.

Match your CV to this job: put the experience closest to what it asks for first, and use the same words the listing uses for the same things.
For each thing the listing asks for, have one real example ready: where you did it, what you did, and what changed because of it.
Informal work counts. Selling, tutoring, running a family shop, volunteering and caring for relatives all built real skills; say what you did plainly.
If a cover letter is asked for, keep it to three short paragraphs: why this job, what you have done that fits, and when you can start.

If there is an interview or a test

Read the listing again the day before, and the organisation's own about page.
Prepare two or three short stories: a problem you solved, a time you learned something quickly, a time you worked with others.
Have one or two questions ready for them, for example what the first three months in the role look like.
For a call or video interview, test your data, battery and a quiet place beforehand. If your connection drops, call or write straight away.

All our tips and messages to copy. Practise answering, with nothing kept. Received an offer? Check whether it is real, then read before you say yes.
