Job description

Job Description

Ciklum is looking for a Senior IoT Engineer to join our team full-time in India. We are a custom product engineering company that supports both multinational organizations and scaling startups to solve their most complex business challenges. With a global team of over 4,000 highly skilled developers, consultants, analysts and product owners, we engineer technology that redefines industries and shapes the way people live.

About The Role

As a Senior IoT Engineer, become a part of a cross-functional development team engineering experiences of tomorrow. The existing CC2012-2 hardware and software platform has been in use for more than 10 years without any significant updates or refreshes. Recently, modifications were required to adapt the CC platform to Hydra, which involved small PCB shape changes and corresponding updates in the firmware. During this process, it became evident that the firmware would benefit from applying modern coding practices and testing methodologies to make the Cleaning Center platform more future-proof, flexible, and easier to update. Partnering with Ciklum for this evolution is a logical step, given the team’s ongoing expertise with the most critical component of the system: the communication between the Cleaning Center and shavers through the 1Interface emulator project. Additionally, the 1Interface initiative has already paved the way for the integration of connected cleaning stations in the future. The natural next step in this journey is to renew the firmware and codebase for Hydra2, establishing a robust foundation. Once this renewal is complete, the platform can serve as a springboard for further innovations and product evolutions in connected cleaning technology.
