Middle Full Stack Developer (вакансія неактивна)


About us

elastic.io is a Germany born product company. We develop the hybrid Integration Platform as a Service (iPaaS) for real-time data sync across disparate cloud-based and on-premise applications, platforms and databases. Our customers are enterprises and SaaS companies all over the world (e.g. Krombacher, Tata Consultancy Services, WWF, Mambu) and many more.

In a nutshell, our platform helps customers easily integrate their business-critical systems (f.e. databases, CRM, ERP, cloud services or whatever) and save money on infrastructure configuration and maintenance.

Basically, a customer can build your integration like a construction set where the pieces are connectors, which can be arranged according to the requirements. It requires a little technical skill and allows customers to stay clear of the programming layer. In more complex cases, the platform allows the customers to create their own integration components or modify the current ones if needed (we have SDK for Node.js and Java). Finally, one can also purchase our product as a white-label solution.

Our Team

Starting from two people in 2013, we have almost 45 people now in Bonn and Kyiv offices, and we’re growing further. Most of the development team is located in Kyiv, there are 20 people here: back-end and front-end developers, QA and devops engineers, integration engineers.

The Role

We are looking for a Middle Full Stack Developer to enhance our Platform development team. You will be developing a core of the product, working on scalability, isolation, performance problems, etc. Please, note that you won’t have to implement actual integrations for customers, we have another dedicated team for that purpose.
