Software Engineer, Backend

What we need

Twelve Data is the company that operates hundreds of terabytes of data that needs to be able to store, process, and transfer between different systems. To solve these problems, we develop our own infrastructure solutions - distributed storage and data processing systems, such as MapReduce class systems, next-generation systems, as well as services that process data in real-time. These systems are used for financial data storage and fast retrieval. Also, our tasks include providing services to thousands of external users.

We are looking for a developer who will work with infrastructure tasks related to the supply of data, improving existing services, and developing new features.

If you know how to bring the matter to the end, like to understand a new challenging field, to show initiative, then our role may suit you.

Basic Requirements:

• Experience in development of applications in Go.
• Knowledge of algorithms and data structures.
• Understanding of the basic principles of building distributed storage and data processing systems.
• Understanding the essence of relational databases and NoSQL solutions, as well as the boundaries of their applicability.

• Have excellent understanding of multi-tier architectures: web servers, caching, application servers, load balancing, storage.

These requirements stem naturally from our approach to development with a fast feedback cycle, lots of challenging tasks, and highly-focused personal areas of responsibility.
