Podsumowanie oferty

Build and run parts of FYUL’s security telemetry and detection platform as a member of its cybersecurity engineering team. The role covers detection engineering, cloud and endpoint security, vulnerability management, and security automation across AWS and Kubernetes, including custom ML detections and AI agents.

Wymagania

5+ years in security engineering or SecOps roles, with hands-on production responsibility for detections and incidents.
Hands-on detection engineering experience with a modern SIEM or security platform; Elastic Security is preferred, and Splunk, Sentinel, or comparable platforms are accepted. Willingness to extend beyond built-in rules into custom ML-based detection.
Hands-on mastery of Linux, macOS, and Windows, including internals, hardening, and investigation on all three.
Strong networking expertise, including TCP/IP, routing, VPNs, firewalls, and packet-level analysis.
Strong cloud security foundation in AWS, including Kubernetes, and experience securing and monitoring production cloud workloads.
Hands-on experience building or operating LLM-powered tooling such as agents, pipelines, or detection and automation workflows.
A practical infrastructure hacking or hardening certification, such as OSCP, OSEP, or a comparable hands-on offensive credential.
Demonstrated automation capability through scripts, integrations, pipelines, or AI-assisted workflows.
Self-directed working style and strong ownership, including the ability to take ambiguous problems through to completion with minimal supervision.
Excellent written and spoken English.

Nice to have:

Further certifications such as CISSP, GIAC/GCFA/GCIH, or AWS Security.
