Sadly all I got so far are applications coming from India and China from people who clearly didn't read the ad and will just apply to anything.
As noted elsewhere in the thread, please keep in mind that salaries in Europe are generally much lower compared to the States :)
I'll take your word for it that in Dublin it's a fair salary---but if you have a small hiring pool and do nothing to stand out, you shouldn't complain that SO Careers gives you few leads.
Also I wonder about your expectations. You call this a good salary "for a developer at the beginning of his career." But you are looking for C#, Angular, Python, R, Matlab, Mongo, and Hadoop. Yikes! Maybe you should cut it back to just C#, put "Junior Developer" in the title, and say you'll provide training time+budget for the other techs. Or leave the requirements and offer a range that is good for someone with 5-10 years experience.
Sorry to be so critical. Best of luck to you. . . .
We are definitely going to consider all the suggestions in this thread, including hiring remote workers and increase our investment to stand out more.
In a way, what is making me doubt the tool is that I haven't received a single application that I could even consider interviewing - just clearly copypasted messages from developers on the other side of the world. I guess I'll see it through when we switch to other candidate search platforms in a few days...
If someone really needs those skills to do the job, then perhaps you can transform a negative into a positive: "New hire will receive on-the-job training time and budget in Mongo, Python, and Hadoop." That would attract a lot of people! And probably adding training is cheaper than raising the salary.
Once your ad has a clear message, perhaps you can use it in more targeted venues than SO. Imagine a CS student at Dublin University seeing a flier on their department bulletin board:
Junior C# Developer Wanted
Excellent Salary
Will Train in Python, Mongo, Hadoop
Even better would be to s/Excellent Salary/€35 - 45k/.
Also, I am a developer with 4 yrs experience in C#. But from my exposure and that of others who work on C#, its more of a backend crowd and Javascript is only used for testing out Node.js or playing with JSON. I am also involved in data analysis. The only time I used Jquery was when I tried to make my data look pretty using Bootstrap and jquery comes bundled with it.
It might be the way I work is different from yours but AngularJS & C# are two different worlds and anyone who understands C# will be able to pick up Javascript by referring MozillaDN.
Now, this is just my personal opinion and I do not want to be attacked for my views. But I feel that now a days, SO has lost its quality and answers are just copy pasted. Mainly the answers have no relation to the question. Especially when you try to compare 2 technologies, the answers are more like fanboys chants than voice of experience.
