Lingokids' mission is to break down language barriers and provide equal opportunities for kids all around the world.
To help deliver our educational content to millions of families, we’re looking for a Senior Backend Engineer.
At Lingokids, we encourage candidates of all different backgrounds and identities to apply. We actively seek to hire individuals with different perspectives, and we are eager to continue diversifying our company's culture. We strive to be an inclusive, supportive place where you can do the best work of your career.
Our offices are in Madrid, Spain, but the position is open to anyone with experience working remotely. Some overlap with Central European Time is expected, though, for those times when a video call is the most efficient way to communicate.
About the job
As a Senior Backend Engineer, you will be in the Monetization squad to get a chance to work on internal tools that help us understand our users and offer them precisely what they need.
More specifically, you will:
- Bring your analytical skills to early product definition and help shape product ideas into technically feasible features.
- Document product, technical, and architectural decisions for engineering and product audiences.
- Do the integration with App Stores and payment providers.
- Work on a majestic modular monolith built with Ruby on Rails, PostgreSQL, Redis, and Sidekiq.
- Own your work from development to production and ensure its quality, maintainability and supportability.
The ideal teammate for us would believe that communication, empathy, curiosity, and open-mindedness are fundamental to success.
You should have:
- Considerable experience designing and developing APIs with Ruby on Rails (or similar languages/frameworks) that scale to thousands of requests per minute.
- A solid understanding of the backend stack: HTTP, Relational Databases, Background Processing Systems, Asynchronous Messaging Systems
- Some experience in both horizontal and vertical scaling of backend systems
We also look out for:
- A DevOps mentality of owning a service to production.
- A good appreciation for User Experience and have an excellent sight for Visual Design and attention to detail.
Some Responsibilities & Deliverables:
- Design, build and maintain features focused on our scope.
- Participate in the different areas of the development process, coding the app and the API with the squad's help.
- Work with the rest of the squad by bringing new fresh ideas on how we could improve the API's process and infrastructure.
- Setup the needed architecture and structure to achieve the feature.
- Track all code changes and keep the feature codebase clean and working.
- Communicate with the different teams for requesting assets required of the component (art, layouts, audio, etc.)
- Review other engineers' code towards increasing the quality and robustness of the API's code.
English is a must. We are a multicultural team, and we are providing a service in English so, we don't care about certificates, but we expect you to be able to communicate fluently.
You should feel equally comfortable communicating in long-form writing. Given the circumstances, we have become a fully remote company. We believe that being articulate in both spoken and written long-form asynchronous communication is key to working efficiently together.
Experience working closely with non-technical stakeholders to refine requirements and bring them to life is a must. We expect our Backend Engineer to be the driving force for the entire development lifecycle.
