Can OpenCart be repurposed for a job board instead of a store?

I’ve been experimenting with customizing OpenCart for a niche career site.
If you're curious, https : // 247jobincanada.com/ is my actual site.
Is OpenCart flexible enough to handle listings and filters like job titles, locations, and deadlines?

You've reminded me of a Jurassic Park quote:
"Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should."

Yes it could be. No you shouldn't do it.

Use some software that's designed to be a job board like Jobberbase: https://www.jobberbase.com/

Or there are loads of others: https://arc.dev/talent-blog/php-developer-job-boards/
