# Careers
!
We work remotely with a flexible schedule using Scrum and Kanban ideas and specialize in development of low level high-performance networking and data storage systems. Since 2008 and during these years many international high tech companies became our clients, e.g. DDN, G-Core Labs, MariaDB, Percona, Wallarm, CloudLinux.
Besides the custom software development projects, we develop our own open source product . You’ll be dealing with the number of advanced technologies: lock-free, NUMA-aware and cache conscious data structures, SIMD mathematics and strings processing, deep interoperation with the Linux TCP/IP stack and zero-copy network I/O, machine learning. As part of the project we developed the TLS handshakes implementation for the Linux kernel, which significantly outperforms Nginx/OpenSSL and Nginx/WolfSSL. You can watch our  with the Tempesta TLS demo.

We develop our own open source product  along with sophisticated C/C++ custom projects for our clients. Tempesta FW is built into the Linux TCP/IP stack and uses our own TLS and HTTP implementations, deeply coupled with TCP. We built a , which employs low level Linux networking features to test Tempesta FW. On this position you’ll be developing the framework and write a lot of code on the system level, analyze TCP, TLS and HTTP traffic, explore the Linux TCP internals, implement proof of concepts for web and DDoS attacks.
**Responsibilities:**
* Enjoy breaking sophisticated system software 😉
* Reveal as many bugs and vulnerabilities as possible
* Develop the testing framework
* Develop and maintain the CI/CD pipeline (Jenkins)
* Prepare software releases (Ubuntu packages)
**Required skills:**
* Fluent Python, including system modules (e.g. socket, os, sys etc)
* Have solid experience in QA
* Experience with Linux system administration, preferably in database and web server areas
* Good understanding of TCP and HTTP networking protocols
**Good to have:**

# C/C++ Linux developer
Posted on September 6, 2022
We’re looking for talented and experienced C/C++ Linux developers, who can do a lot and want to learn even more. As a part of our team you’ll be developing the fastest open source software, investigate and fix sophisticated performance issues on powerful Linux servers and talk on top technical conferences.
You’ll develop performance and scalability extensions of MySQL/InnoDB (e.g. we made ), the Linux kernel, Nginx and other popular open source projects. You’ll also analyze the performance of heavily loaded large Linux systems and make them even faster.
You’ll be able to talk at major international conferences about the Linux kernel and databases at will.
* Fluent C and good C++ or willingness to learn C++
* Deep understanding of the Linux kernel
* Good knowledge of classic algorithms and efficient data structures
* Experience with multithreading (POSIX threads, C++ STL)
* Experience in the Linux kernel development (kernel/, mm/, net/, security/)
* Some experience with Python to develop functional testing scripts
* Experience in the networking area (IPv4, IPv6, TCP, TLS, QUIC, HTTP)
* Understanding how modern hardware (x86-64 CPUs, network adapters and disks) work
* Experience with Rust or willingness to learn the language
