How to structure it

Opening

Name the role and, in one line, the strongest reason you're a fit. Skip the throat-clearing.

Middle

One or two paragraphs of real, specific evidence: what you did, and the result. This is where most letters go generic. Yours shouldn't.

Why this employer

One genuine, specific reason you want this job at this company, not any company. Vague enthusiasm reads as a template that wasn't customised.

Close

Thank them, note your resume is attached, and make it easy to reach you.

Re: Application for Water Treatment Operator

I am applying for the Water Treatment Operator role at [Company Name]. With hands-on experience monitoring treatment processes, adjusting dosing and taking samples, I can keep your plant running safely and within compliance.

In my current role, I noticed a slow drift in filtered water turbidity during night shift. I reviewed SCADA trends, adjusted the coagulant dose and backwash cycle, and confirmed the fix with bench tests. The plant returned to target within the hour without a non-compliance report, and I documented the change for the next crew.

I want to work for [Company Name] because [add one genuine, specific reason: a project, value, or market position you can point to]. I am looking for a team that takes public health and environmental standards seriously and invests in operator training.

Thank you for considering my application. My resume is attached, and I would welcome the chance to discuss how my shift experience and compliance focus would suit your operations.

Getting it right

Keep it to one page. A hiring manager spends seconds on this before deciding whether to read your resume.
Address a named person where you can find one, rather than "To Whom It May Concern".
Don't repeat your resume line for line. Use the letter to add context a bullet point can't: why this role, why now, why here.
Match the tone of the job ad. A formal listing calls for a formal letter; a casual one gives you room to write more like yourself.

This is a starting point, not a guarantee of interviews. Make it specific to the actual employer before you send it.
