Senior C Developer/Architect

R Systems is looking for an experienced Senior C Developer or  a C System Architect to join our team of innovators and help with overseeing the junior developers on our projects and supporting various development duties.

As a Senior C Developer, your main role will involve writing code, analyzing data, and contributing to the design and implementation of software for products such as:

  • Device Query Interface (DQI) – used by external clients to query the capabilities of a device based on the IMEI, IMSI or MSISDN in real-time. This data will be fetched by the DQI VNF from USD DB
  • BSF (Bootstrapping Server Function) – an intermediary element in Cellular networks which provides application-independent functions for mutual authentication of user equipment and servers unknown to each other and for ‘bootstrapping’ the exchange of secret session keys afterwards
  • USD Proxy (USDP) – facilitates obtaining authentication vectors from HSS via an LDAP search and it also allows clients to access data in the One-NDS without directly connecting to it
  • PLF (PCRF Locator Function) – routes incoming NAP and LDAP requests to PCRF’s and returns the most proper response
