The 14 Best Sourcing Tools for Technical Recruiters

Hiring Developers

sourcing tools for technical recruiters

These days, posting job offers online is not enough to put together a pool of technical talents.

You have to source developers and engineers proactively, inspecting all the places where they might spend their time like a detective. 

This expands the range of tools available to technical recruiters to collect and search passive candidates and make sure to find the best fit.

Here’s a list of sourcing solutions that will get you started (some of them may surprise you!). 

Social Platforms for Technical Sourcing

Social media are always great for sourcing talents. That’s also the case when looking for candidate developers. You just have to be smart and look for channels where technical people love to hang out and post content. You can search through channels like : 


Let’s start with the most popular professional platform. LinkedIn offers an almost limitless pool of potential candidates. You just have to know how to use it and filter very selectively. To do that, you can leverage the advanced Boolean filters via LinkedIn Talent Solutions. With them, you can refine your search lists of candidates based on how closely they match your precise qualifications. You can also check out dedicated groups and communities to find experienced developers in your required language. 


Do you want to get a concrete picture of the experience of potential candidates? GitHub is a platform that enables developers to store all the versions of their coding projects. It gathers a wide community that shares work and ideas. By exploring these projects, you can find contributors that have already extensively worked on specific language and technical projects. This increases your chances to stumble over talents that are a great fit for your company.

Stack Overflow

Stack Overflow is the Q&A platform for developers. When some coders struggle with a difficult technical problem, they can get honest answers and feedback from experienced programmers. Which better place than here to find senior developers for your position? You can use the paid Stack Overflow Talent service to access advanced searching and job advertising tools. The easiest way to find talents on the platform though is to start from Google. Type questions related to the skills needed by your hiring managers, and you might find posts from proficient developers. You might also get precious information from their profile about their current professional status. 


Reddit is an untapped social platform for finding highly qualified candidates. And that’s also the case for technical talents. As developers love to chat about all kinds of subjects on Reddit, you might meet a lot of interesting passive candidates. To leverage this platform, you can search for users that have posted about their job search. You can also infiltrate Subreddits that are chatting about specific technical subjects (like r/python). One golden rule here: connecting with users before pitching them.


Quora is another Q&A on more generalist subjects but with a wide audience. Quora’s users are asking and answer questions related both to their professional and personal lives. All these discussions are stored in theme-based sections called “spaces”. By checking on technical niche spaces, you might easily find qualified experts and potential candidates. However, as Quora is not a recruiting platform, you have to be careful not to be reported as spam and advertising.  First, contribute to the platform and trigger conversations with people of interest, and then only connect casually with them. 


You know Twitter as a place for lively debates and fun discussions, but do you know that it’s also a great place to reach out to developers? You can use the Twitter search advanced filters to catch up on technical discussions about subjects that fit your job description. You can also check user-generated Twitter lists related to your topic. Twitter users’ profile will display all their Tweets and some personal information that might make you an idea of their skills. You might then contact them through Twitter messages directly or through other means.
