You'll design, architect, and drive security posture changes for Palantir, and work to make life hard for our adversaries.

    • Design, architect and build automated systems to provide security uplift for the organisation
    • Perform security evaluations and research on new platforms, products, architectures, vendors, and services to protect Palantir data
    • Partner closely with other members of the Technical Operations, Engineering, and Information Security teams to drive impactful changes to the company’s network defense posture

What We Value

    • Comprehensive knowledge of modern adversary tactics, techniques, and procedures.
    • Ability to independently own projects and balance competing priorities, while still effectively collaborating with colleagues.
    • Experience with public cloud service providers (e.g. Amazon AWS, Google GCP, Microsoft Azure).
    • Experience with infrastructure automation platforms (e.g. Packer, Terraform, Ansible, Puppet etc.).
    • Proficiency with at least one scripting language (e.g. PowerShell, Bash, Python, or similar). Experience in Golang is a plus.
    • Willingness and eligibility to obtain a UK security clearance.
