About the role

  • Senior Probe Appliance Engineer taking ownership of COMPASS probe appliance at CryptoNext. Work involves kernel optimization, network performance, and support for quantum-safe cybersecurity efforts.

Responsibilities

  • As Senior Probe Appliance Engineer, take full technical ownership of the COMPASS probe appliance.
  • Deploy, configure, and maintain the COMPASS probe appliance (hardware + Linux OS).
  • Perform OS-level and kernel-level hardening (CIS benchmarks, secure boot, file integrity, access control).
  • Optimize the appliance for high-throughput packet capture using DPDK, AF_XDP, or zero-copy capture frameworks.
  • Guarantee secure, reliable ingestion into Kafka pipelines.
  • Collaborate with R&D teams to integrate parsing modules, firmware updates, and kernel patches.
  • Implement monitoring (metrics, logs, health checks).

Requirements

  • 10+ years of experience in system engineering, network engineering, or infrastructure security.
  • Master’s degree from a French engineering school or equivalent.
  • Deep expertise in:
  • Linux system administration
  • Kernel tuning and OS-level performance optimization
  • Networking, packet capture, and traffic analysis
  • Experience with:
  • CIS, NIST, or ANSSI hardening methodologies
  • Hardware optimization (CPU pinning, NUMA, NIC queues, hugepages)
  • Kafka or streaming ingestion technologies
  • Automation scripting (Bash, Python, Ansible)
  • Excellent documentation skills and rigor.
  • Fluent in English.

Benefits

  • Shape a core component of a next-generation cybersecurity product.
  • Work on challenging, low-level engineering problems involving kernel optimization and network performance.
  • Collaborate with senior engineers and cryptography experts.
  • Flexible hybrid/remote work with a central Paris office.
  • Competitive compensation aligned with seniority.
  • Direct impact on the technical backbone of a quantum-safe observability platform.
