The Security Engineer will be a hands-on technical contributor, acting as a bridge between initial triage and high-level security architecture. You will move beyond simple monitoring to active investigation, incident handling, and the implementation of security controls. This role requires the ability to work independently on routine security operations while collaborating with senior engineers on complex threat scenarios and cloud architecture.

You will be responsible for maintaining SOC capabilities, executing offensive security tasks, and assisting with automation efforts. This role reports to the Head of Information Security.

• Perform security reviews of internal tools and new features, providing actionable feedback to development teams.

• 1–3 years of hands-on experience in Information Security, SOC, or a related technical field.
• Deep understanding of networking (TCP/IP), operating systems (Linux/Windows/macOS), and web application security (OWASP Top 10).
• Practical experience securing resources in at least one major cloud provider (AWS, Azure, or GCP).
• Proficiency in Python, Bash, or similar languages for automation and parsing logs.
• Demonstrated ability to investigate security events, analyze logs, and understand the lifecycle of a cyber attack (MITRE ATT&CK framework).
• Ability to solve technical problems with minimal guidance and manage your own queue of tasks.
• Ability to explain security risks to non-security colleagues (e.g., developers or IT staff).

• eJPT, GSEC, CySA+, SSCP, or Associate-level Cloud Security certifications (e.g., AWS Certified Security – Specialty).
• Familiarity with Docker and Kubernetes security concepts.
• Experience with SAST/DAST tools or code review.
