"Seeking a challenging position that utilizes my skills." Delete it. That sentence has told the reader nothing they didn't already assume the moment they opened your resume. Of course you're seeking a position. Of course you want to use your skills. You applied.
The objective statement was built for a different job market, one where a resume got mailed to a general pool and a company needed to know which department to route it to. That's not how anyone hires now. You applied to a specific posting for a specific role. The company already knows what position you want. Telling them again is wasted space at the top of the page, the spot with the most attention of anywhere on the document.
What actually earns that space
A professional summary, two to three sentences, written for this specific job. Not what you want. What you bring. "Backend engineer with 6 years building payments infrastructure at scale, currently leading a team migrating a monolith to event-driven services" does in one sentence what an objective statement can't do in three: it proves you can do the job before the reader gets to a single bullet point.
The test for whether a line belongs at the top of your resume is simple. Could a hiring manager use this sentence to decide whether to keep reading? "Seeking a challenging position" fails that test completely. "Led the team that cut infra spend 40% while doubling throughput" passes it instantly.
The one exception
Career changers get a partial pass, and only a partial one. If you're moving from teaching into UX research, a line connecting the dots, "Former high school teacher applying six years of stakeholder communication and curriculum design to UX research", is doing real work. It's not stating a want. It's making an explicit case for relevance the reader wouldn't otherwise draw themselves. That's the bar: if the line is building a bridge the reader needs, keep it. If it's just announcing your intentions, cut it.
What to do with the space instead
Move your best line up. If your strongest bullet is currently third under your most recent role, it should probably lead your summary instead. The top third of a resume gets skimmed hardest and remembered longest. Spend that real estate on evidence, not on a sentence that could be pasted onto anyone's resume for any job and still technically be true.
