• Experience in driving mobile application development from the conception phase to the deployment and maintenance
• Willingness to embrace and adopt new technologies and methodologies;

• Work at our HQ (Warsaw, Służew metro station) or remotely;
• Comfortable, spacious office with a large backyard (we have frequent BBQ parties);
