So happy to read your feedback, Pieter! Portugal is definitely a small market and my main goal is to create some value for the local startup scene. Not expecting to pay the bills and I do agree with @marc when he says that the difficult part is having a targeted audience that employers are willing to advertise their job listings to.

The job board would be be connected to a Slack community focused on the Portuguese startup scene (already exists) and my hope is to work alongside incubators and coworking spaces to make it more relevant.

I didn't think about SEO optimisation. Thank you for the tip!
