Ask HN: How to find a writing job within a start-up?

I've been building websites for the past decade or so, and currently make a living doing so (running blogs, a forum, and a YouTube channel), but I've also been actively focused on writing these past few years and would like to move my career in that direction. Because of my technology background, I'd love to be a writer within a start-up, and was wondering:

How would I find a writing gig within a start-up?

I'm familiar with some of the job-seeking sites focused on start-ups but, understandably, most of the jobs are focused on engineering and I'm finding it difficult to wade through all the listings.

Any help would be appreciated.

Thanks.
