The team

Kraken is looking for an experienced Linux engineer to join our Infrastructure Performance and Security Team. In this role you will be focused on applying best security practices to our underlying infrastructure while using data driven strategies to performance tune multiple low-level exchange services. We are looking for an extremely strong communicator and team-player, who is able to break down large complex problems into smaller more manageable problems-to-solve. You will take the initiative to explore different ways to resolve an issue, and systematically find the most efficient and effective way to unblock yourself and other teams.


    • Be responsible for managing the Linux kernel and operating systems for all our on-premise servers, both from a low-latency performance and security perspective.
    • Tune and optimize both the Linux kernel, operating system and associated hardware.
    • Work closely with the various SRE/Dev teams to ensure applications run optimally and securely.
    • Automate everything from kernel builds and testing, to ‘at scale’ production deployments.
    • Integrate kernel and operating system configuration with IaC tooling.
    • Improve the current observability, monitoring and alerting associated to your areas of responsibility.
    • Work on a common container platform that’s used by SRE/Dev teams.
    • Provide architectural input and peer review across multiple teams and exchange services.


    • 5+ years of experience working with Linux kernels and operating systems.
    • Advanced knowledge of Linux, focussed on automation and performance tuning. Able to squeeze every bit of performance out of the servers our trading engine is running on!
    • A deep understanding of security. You know your way around Linux kernels and how to tweak them to build extremely secure environments.
    • Building automated performance benchmarking, leveraging CI/CD technologies.
    • Knowledge of low-latency networking (Solarflare/Xilinx onload) and knowledge of the network protocols.
    • Strong with scripting languages (Bash, Python)
    • Experience with Infrastructure as Code tooling (Terraform/Kubernetes, Ansible/Salt)
    • Experience with containerisation (Docker, KVM)
    • CI/CD & toolchains (Gitlab, make, gcc)
    • Experience with software-defined storage systems (Ceph, Gluster)
    • Knowledge for Cloud Platforms such as AWS, Google Cloud.
