It’s been one of those weeks again – one of those weeks where the Irish tech market has exploded with job opportunities.

This week saw job opportunities being announced by the boatful. Over 500 were announced in total, from smaller expansions (Blueface and OneSource) to massive growth (LinkedIn and Limerick IT).

And, speaking of LinkedIn, this week gave us a brief glimpse into what it’s like to work at the social media site. We spoke to Cliona Moulton, who had emigrated from Ireland, but recently returned for a job at LinkedIn Dublin.

But not all jobs-related news this week was about recent announcements. We spoke to Lisa Cahill, HR manager at BMS, who talked to us about what the biologics company is looking for from candidates for the 400 job opportunities announced just last month.

Some of these job opportunities will be taken up by candidates moving to Ireland from abroad. This week, we discussed the results of a LinkedIn survey which stated that 18pc more professionals are moving to Ireland than are leaving.

Perhaps some of the draw is the culture (and perks) offered by the leading international tech companies HQd here. The likes of Google and Facebook, as John Kennedy so eloquently laid out this week, offer a company culture far above and beyond what is accessible elsewhere – certainly a draw for EMEA tech talent looking for job opportunities.

As always, of course, there was also a healthy dose of skills development news this week.

The world is currently gearing up for the Hour of Code, a global, week-long event which aims to encourage programming enthusiasts of all ages, and all skill levels, to do some coding. We took a look at some of the events that will be on offer around Ireland.

Of course, coding isn’t just an hour-long, or even week-long, affair. Organisations like CoderDojo push the coding agenda year-round, encouraging children to dive into the world of coding. This week, it was announced that a group of MEPs have ordained themselves, informally, as ambassadors for CoderDojo, promoting computer coding skills to youngsters around Europe.

Finally, we turn to the grown ups, who are also having a good week when it comes to coding. This week, it was announced that global non-profit Women Who Code has welcomed it 50,000th member. Congratulations!
