Cover letter for an over-qualified applicant taking a step down

On paper you are too senior for this job, and that worries the hiring manager more than it reassures them. They fear you will be bored, expensive or after their seat. This writes a cover letter that gives your honest reason for wanting the role, shows how you will add value without steamrolling the team, and heads off the obvious concern before they raise it.

Write me a cover letter for a role I am over-qualified for on paper.

Role I am applying for: {TARGET_ROLE}
Company: {COMPANY_NAME}
My current or most recent role: {CURRENT_ROLE}
Why I genuinely want this specific role despite being over-qualified: {HONEST_MOTIVATION}
How I will add value without overwhelming or undermining the team: {VALUE_ADD_APPROACH}
Any concern the employer is likely to have about hiring me: {ANTICIPATED_CONCERN}

Constraints:
- Maximum {WORD_LIMIT} words
- Address the over-qualification question directly in the opening paragraph; do not hope it goes unnoticed
- Give a credible, specific reason for wanting this role that goes beyond 'I just want a change'
- Reassure the reader about longevity and team fit without being defensive
- Emphasise what this role offers me that a more senior role does not
- Tone: grounded and honest, not apologetic
- Do not downplay experience; reframe it as an asset for this context
