Just a minor troll: I have 10+ yrs experience with Django, none with RoR. I suspect I could take a RoR position and do just fine, budgeting myself 5-10 hrs non-billed per week to get up the learning curve.

But why would I do that when all the evidence I've seen lately is that Python + Node are the present & future (maybe add go, rust), whereas RoR peaked years ago and is becoming a legacy/maintenance job? Why fill my head with that?

When is the last time anyone has heard of a company building from scratch on Ruby?

Yes it is. The job ad states:

We’re looking for candidates with a strong track record of putting Rails to work and bringing products to life. You should be experienced in the framework, in Ruby, and with the staples of full-stack web development: HTTP, HTML, JavaScript, and CSS.

Thanks the the update. The reason I ask is because it severely limits the applicant pool.

For example, I have years of Django experience, and now I work fully in Nodejs/TS. Anecdotally, this is the case for a lot of people that I know. Moreover, I don’t see a situation where I can get deep RoR experience from the industry now.

Do you see this sentiment from other applicants? How are you getting enough RoR experts?

> How are you getting enough RoR experts?

This is very interesting. At my company we've had problems with finding senior Rails devs, which constrasts with the "great resignation" theory.

I think that the pool of senior RoR devs is restricting nowadays (due to the framework/language's loss of appeal), but the is a small number of Rails big techs (and famous companies, including 37signals) that are still very desirable, so they may not have problems in finding candidates.

You need senior Rails devs? I could apply. What's the company?

Indeed, and presumably given DHH’s philosophy, 37signals intends to be in business for a very long time.

How will they ensure a stable pipeline of experienced RoR engineers?

Sidenote - IMO Django and RoR are unmatched in developer productivity - all modern alternatives have mind-numbing levels of boilerplate and bike shedding.

37signals will never have trouble hiring, they are so well known and respected.

My point is that the supply of RoR engineers is limited and dwindling. It’s not sustainable long term. Maybe 37Signals thinks otherwise…

You’re wrong, Rails is still very much alive. Also the idea of x language developer is outdated, as long as you know the language and framework and have done more than nothing with it there’s more flexibility these days especially for senior engineers.

Rails may very much be alive, but this thread began because strong RoR experience is mandatory for this role. This isn’t a generic discussion.
