• Establish clear priorities for automation based on product risks and release needs.
• Help the team evaluate and plan the initial mobile automation setup for iOS and Android.
• Contribute to a faster, more predictable, and more reliable release process.

Benefits:
 

• get 4 weeks of paid vacation each year for rest and adventures;
• work flexible hours for a better balance between work and personal life;
• enjoy medical insurance for your peace of mind;
• nurture your professional growth with the support of Launch Labs, as we'll pay for your professional courses and training;

Who we are 

We are a Ukrainian multiproduct company that creates database development and management tools, connectivity solutions, productivity tools, and data services for more than 500.000 clients from 120 countries. Among our clients, you can find such legends as Microsoft Corporation, Oracle America, IBM, Intel, and many more companies that deserve their place in the Fortune 100 and Fortune 500.

Since 1997, we have been streamlining data workflows for professionals and teams with our intuitive and efficient software products. We’re committed to enhancing our customers’ experience across the globe by minimizing data-related tasks and enabling them to focus on more inspiring goals. Whether it’s Fortune-100 companies or individuals, we provide a customer-centric approach, delivering high-quality solutions and exceptional support.

Driven by passion, we play a substantial role in shaping the future of data management.

The product that needs your engagement

The role is open as we grow the team building our new greenfield platform.
