We're an award-winning company helping parents raise bilingual kids at home. We create a safe environment for children 2-6 where language learning just happens.

We're looking for a Sr backend engineer to join this adventure. We work primarily with OpenResty / Ruby on Rails / Redis / MySQL on top of AWS services (EC2, Cloudfront, S3..)

Monkimun, Inc. | Language Learning for kids 2-6

Position: Senior game developer, Unity3D

Location: Madrid, Spain (onsite)

Monkimun is an award-winning company that makes Language Learning for Kids fun. We create a safe environment for children 2-6 years old where learning just happens.

We use a Unity3D / RubyOnRails stack and develop our own native plugins directly in iOS/Android. We also use many AWS services (S3, Route53, Cloudfront, EC2..) and bare-metal servers (OVH/Hetzner).

We're looking for a senior engineer to grow our development team. Unity3D knowledge is required. Many years of experience are _not_ required - the most important thing is a well rounded engineer (data structures, algorithms, etc).

Other requirements: High motivation to learn and grow, know what it is to work in a serious (-ly fun) startup (high pace, pressure, attention to detail..). Our mission is to change the way small kids learn languages, this should drive you too.

I never quite understood why everybody thinks storage should be in the local server and cannot be provided by a private company.

IMHO, storage is a commodity.

Would you argue that schools need their own power generators because otherwise they'll be submitted to private companies? Should schools also have their own satellites and internet connections?

If the data is sensitive why not just encrypting it when is stored the same way we do when we need to transmit something over the wire?

Now, from the school POV I think if they go for a private solution they should demand open standards (avoid being locked in) and appropriate SLAs.

Same in Madrid. Twice entrepreneur. Not an expert but I know what it is like. Coffee or a beer, whatever is good.
