Does curated job listing in niche are still good?

Hello i'm new here in IndieHackers i'm currently building a side project which is Curated Job listing in specific niche?

I'm just curious if this is still valid idea to build and do you think i'm planning to build as simple where recruiter and company can add a job. no more sign up for both recruiter/company and or job seeker.

I already have the front end i'm still improving the backend at this moment.
