Purpose of the Role
This permanent role will lead the integration of CSignum products into larger systems. CSignum manufacture a unique low frequency radio modem that enables short range underwater data communications and transmission from submerged equipment, through the water‑air boundary. Our modems typically interface with subsea measurement and control equipment, relaying data to the surface, where we interface with conventional terrestrial radio equipment for long range onward transmission. Integration typically requires battery power management implications that often accompany a move to wireless data transmission and adaptation of the system architecture to accommodate the low data rate, half duplex serial communications our modems deliver.
CSignum is an expanding start-up and ideal candidates will be able to bring experience of process-heavy environments but adapt their approach to an agile and dynamic company, and enjoy a varied workload.
