Working at SIXT not only means creating the future of mobility, but also offers personal benefits. This means especially for you: 30 days of vacation, no dress code, choose your own device, support for pension plans & capital-forming benefits, mobility allowance of 20€/month and flexible working hours. Due to the current situation, we are of course working completely in mobile work wherever possible. But even under normal conditions, from now on you can decide from where you want to approach your work: Up to 50% of your monthly working time you can work completely mobile and from anywhere, of which up to 30 days per year in other European countries (EU, CH & UK). In addition, we offer you a super international working environment, numerous trainings for your individual development, participation in external conferences and we even organize internal dev & tech talks. Our Feel Good Manager will be happy to help you with the organization or to assist you when you move to Germany from abroad and need to organize visas or other administrative procedures. It's also important to balance out your work: That's why you have access to our employee restaurant (and yes, we insist on restaurant, because it's too high quality for a canteen) as well as various recreational opportunities such as the gaming area, the SIXT soccer team or the SIXT choir - to name just a few. In addition, of course, employee benefits for SIXT rent, share, ride and SIXT+, car leasing offers, discounts with partners for travel, technology, clothing, etc. as well as free cyber sports courses. In addition, your colleagues are pretty awesome. Which is important when you spend so much time together, and besides, no wonder when you get a bonus for referring friends as new employees. If something does bother you, you'll always have someone to confide in through regular feedback sessions, employee surveys or our psychological hotline through the Fürstenberg Institute. Otherwise, we live "work hard, play hard" - our parties are legendary! We also demand and promote DiverSIXTy, a corporate culture of acceptance, appreciation, and respect, in which everyone can develop their personality and ideas.
