Software Engineers (SolarSecure) [ref: SwSnrSSFEEng, SwPrncplSSFEEng]

We are looking for very high calibre software engineers to work on the design and implementation of Solarflare's SolarSecure packet filtering engine. SolarSecure is a distributed active security solution working in conjunction with Solarflare network adapters to provide server level protection for mission critical systems and networks against cyber threats. Central to SolarSecure is a high performance packet filter engine which executes microcode instructions to perform deep packet inspection resulting in selectively accepting, rejecting or rate-limiting packets.

This role involves working in C on an ultra high performance packet filtering engine that typically runs as part of a kernel module offloading some support into the network adapter. To be successful you will have the ability to quickly understand a complex hardware and software architecture. You will have worked extensively at the hardware / software interface involving networking in some capacity, programming in C ideally on Linux kernel components.
