Advantages of Working with Exadel:

Transparent Career Roadmap: The HR manager accompanies each employee on their first steps in the company and assists them in achieving future professional goals. Exadel is a global company with 30+ offices in 15+ countries. Employees can discover new places to live and work and transfer to any location with an Exadel production office. The HR manager and the Global Mobility specialist accompany the employee and assist throughout the relocation process. Your career growth is in your hands, so each Exadeller decides when to level up and initiate performance assessments.

The management team supports career planning and the discovery of new tech stacks and languages.

Learning & Development Opportunities: We believe in nurturing talent and fostering growth. That’s why we offer an annual dedicated budget for your continuous learning journey. From professional development courses to books and certification, we’re invested in your success. Employees participate actively and benefit from the knowledge-sharing environment across seven practice units: Digital Marketing Technologies, Content Marketing, AI, QA, QAA, Agile, and DevOps. Employees can find recordings from meetups and trainings on Exadel’s Internal Learning System.

Work & Life Balance: Each Exadeller is in charge of managing their workflow independently without being micromanaged at every step; it is, however, important that an employee always attends meetings, logs their time, and meets deadlines. Operating from the office or remotely depends on which mode the employee prefers. Hybrid or remote mode staff will receive the necessary equipment before their first working day. For those who prefer to work in-office, the office network offers up-to-date equipment, good facilities, and a warm collaborative environment. The team meets at two annual team-building events across locations; in addition, there are team events such as Pizza Days, Programmer’s Day, informal meetups, board game parties, and sports initiatives.

Employee Perks & Bonuses: The Exadel referral program covers all regions and involves recognition for hired recommended professionals. Depending on the location and the position, an employee receives a monetary bonus for recommending a candidate to Exadel who ends up being hired. Employees collect coins for numerous project activities, exchanging them for products or services of their choice available on the Exadel store. Volunteers for mentoring, interviewing, performing assessments, and participation in community meet-ups, get additional monetary bonuses. Location-dependent, Exadellers can access benefit platforms with vouchers for online stores, medical insurance reimbursement, sports membership fees, vacations, and childbirth bonuses.
