Fullstack Engineer To Help Build The Future of Social Networks

Found in: beBee S DK - 4 weeks ago

Copenhagen, Denmark Doubble Full time

are you excited about the idea of using your fullstack engineering skills to make the future of social networks less about followers and more about close friends?

then we might have an interesting opportunity for you


why we are building Doubble?

🍀our vision is to build a close friend social network to help solve loneliness

at Doubble we build the future experiences we create with our close friends

the first step was to build our double dating app that allows you to meet new people with your friends

meeting new people is a big part of Doubble, but the less obvious, yet most important secret ingredient in Doubble is: the close friends.

in the era of social networks, this is the paradox of our time: it’s never been easier to connect, yet we feel lonelier than ever.

our generation spends 3 hours per day on social networks, but only 3 hours per week with close friends.

today’s social networks solved boredom, but not loneliness.

the social networks missed an important insight: you can feel just as lonely with no friends as with hundreds of friends. it’s when we’re together with our close friends we feel the most connected.

that’s why focusing on the experiences we create with our close friends has never been more important than right now.

if done right, the close friend social network category can solve loneliness, and Doubble will be a key piece in this close friend social network puzzle.Where are we going?

🏎️Doubble is in the midst of a global scale race

Doubble started in Denmark and the numbers clearly show we built something our generation needs:

55% of gen z dating users in Denmark are on Doubble

we process more than 300 swipes per second

+200.000 users

What we did in Denmark, we did 5x faster in Sweden, then Norway, then the Netherlands, and most recently, the United Kingdom.

we’ve proved to the world that there is a way to meet new friends with your close friends, but the problem with proving it to the world is that we’re also proving it to competitors.

we are on our competitor’s radar. we are in the middle of a global scale race and the question is: will Doubble get global scale before a competitor copies us?


What joining Doubble means for you?

🤝greatness doesn’t come easily

there is no need to sugercoat that joining Doubble and winning the global scale race will be intense.


Doubble will be your opportunity to prove that you are an elite operator

you can get really far by either working hard or working smart, but to win the global scale race you have to do both. we put everything we have on the field, so you shouldn’t be surprised to see your team mates working 9 to 21.

winning this race is an accomplishment only an elite operator can achieve.


Doubble will be your opportunity to make history

taking Doubble to a billion dollar company will require significant portions of your time, but if we succeed, you’ll be able to look back and say:

“i was a part of building the largest consumer company in Denmark since Lego”


Doubble will be your opportunity to change the trajectory of social networks

today’s social networks have solved boredom.

if done right, a close friend social network can solve loneliness, and Doubble will be a key piece of this close friend social network puzzle.

we celebrate together

our milestone roadmap includes a celebration for each. we believe that to build a fun product experience, we need to have fun in the process and we generally try to gamify our work.


talk is cheap so you should do more of it
