Salaries upto 40L! Before you think this is a marketing gimmick, please read about our mission below: On one hand, global managers are hungry for driven full-time talent like you but are sick of going through outsourcing companies to access you (where 30 lakh of you are stuck). In fact, outsourcing for them has become a bad word. You on the other hand have no way to directly access these global managers. At times, you might think the large captive centers are a better option only to be disappointed by the lack of engaging work given the local bureaucracies and global colleagues thinking of these Indian captive centers as mere ‘back-offices’ leading to the ‘us vs. them’ sinking feeling. kaam.work is on a mission to connect these global managers directly with you. Global managers’ willingness to pay globally competitive salaries and our engagement model to directly connect you to them avoids the need to splurge on “massive campuses” or “local managerial layers” thereby resulting in more money in your pockets and a more enriching working relationship at both ends. To be transparent and set the right expectations, not everyone who applies will get Rs 40L salaries and your exact salary will depend on our assessment of your skills and capabilities. Our average increase over current salaries has been more than 80%. What will you get ? Salary of Upto 40 lacs Global jobs connected to global managers - no local managerial layers Modern work location & modern culture (cool co-working spaces like in the pictures) Work matched to your skill and passion - this is at the core of the kaam.work technology Upfront as well as steady-state training and/or mentoring *to ensure you are successful* working in remote environments We have an audacious vision to alter how global companies engage Indian talent: a vision that involves building a KaamForce (our take on tomorrow’s WorkForce) comprising gritty, hungry, and passionate individuals such as yourself serving as integrated full-time team members for talent starved global companies. Join us in this movement! Sounds exciting ? Apply now ! Questions ? Contact us or visit our FAQ page
