Lingokids mission is to remove language barriers and provide a quality education for all children around the world. To achieve it, we are building a great technical team and we’re looking for an exceptional Mid Backend Engineer that will be joining our HQ located in sunny Spain.


We’re reinventing early childhood education through an online language learning service for kids. With fresh content - games, books, videos, interactive episodes, etc - every week, we are helping more than 11M families and their children around the world learn English in a fun and effective way. Our dream is to have a positive impact on 100M families and we’re working hard to make it a reality. Our talented team of product designers, software engineers, and content producers tweak and improve our product daily, while incorporating feedback from our customers.


We need a well-rounded backend developer with experience in designing, prototyping, implementing, documenting, maintaining, and debugging robust backend systems at scale.

You will get to work on:

*Our in-house billing system that provides a centralised subscription management system for our product that integrates with AppStore Connect, Google Play Billing, and Stripe Billing.
*An event processing pipeline that receives thousands of user generated events per second, stores them, transforms them, and forwards them onto a number of 3rd party analytics services.
*The content management system that delivers our weekly in-house content to our customers.
*An infrastructure topology that includes AWS-hosted computing capacity, multiple Postgres databases, message brokers, background workers, CDNs, in-memory caches, etc.
*And of course, a slew of interesting customer-facing features that you will help define side-by-side with our product folk.
*Our stack is Ruby on Rails, Postgres, AWS, Redis, React Native, and Unity 3D. We prefer to pick the right tool for the job over trendy new tech.


*Believe that written and spoken communication is the most important skill to solve any engineering problem.
*Have soft skills that include empathy, inquisitiveness, and open mindedness; we are not big on dogma or cargo-culting here.
*Thrive when working as part of a diverse, multicultural, multi-disciplinary team.
*Relentlessly seek simple, elegant solutions to complex problems.
*Have at least 3 years of experience in designing, building, maintaining, and evolving backend systems.
*Are an engineer with a solid grasp of distinct programming paradigms, system architectures, development methodologies, and testing approaches. And you know when to use each one.
*Have worked at a fast-paced, agile, product-oriented technology company before.
*Experience developing projects in ruby on rails is a highly valued resource.


Furthermore we are proud of our culture and work hard to make sure every team member loves what they do. Check some of the perks and benefits of working in the EU and being a Lingoer

*Holidays: 23 days of paid leave, and 14 days of bank holidays a year!
*Family Leave: Enjoy up to 4 months of paid family leave, regardless of when you joined.
