As a Cybersecurity Operations Engineer, you will play a key role in safeguarding enterprise systems, data, and infrastructure across IT and OT environments. This role focuses on operational security excellence, including continuous monitoring, threat detection, incident response, and security engineering, while supporting compliance and resilience objectives.


You will work closely with the CISO office, SOC, IT, OT, and engineering teams to ensure security controls are effectively designed, implemented, and operated. This role is suited for individuals who enjoy hands-on security operations and engineering in complex, fast-moving environments.


Key Responsibilities

Threat & Vulnerability Management



  • Coordinate vulnerability assessment and penetration testing (VAPT) activities with internal teams and external service providers.

  • Manage security findings from penetration testing, red teaming exercises, and bug bounty programmes, working with stakeholders to prioritise and remediate risks.

  • Recommend appropriate mitigations and implementation actions to address identified vulnerabilities.

  • Track remediation activities, security deviations, and risk acceptances through to closure.


Security Engineering & Architecture



  • Partner with the CISO office to conduct security architecture reviews, evaluating the design and effectiveness of security controls across systems and networks.

  • Collaborate with SOC, IT, OT, DevOps, and Physical Security teams to ensure cybersecurity operations align with enterprise architecture and operational requirements.

  • Support the integration of advanced monitoring, detection, and security automation capabilities in line with organisational standards.


Incident Monitoring & Response



  • Monitor security events and alerts, detecting, containing, and remediating security incidents in a timely manner.

  • Handle incident escalations from the SOC, performing deep-dive technical analysis and coordinating with engineering teams to resolve complex security issues.

  • Monitor and respond to indicators of compromise (IOCs) and emerging threat intelligence to reduce exposure to known threat vectors.


Compliance & Risk Management



  • Implement and validate technical controls to support regulatory requirements and internal security policies.

  • Conduct ongoing risk assessments and contribute to continuous improvements in security posture.

  • Provide technical input and evidence to support internal and external audits.


Skills and Experience



  • Bachelor’s degree in computer science, Information Security, or a related discipline, or equivalent practical experience.

  • Proven experience in cybersecurity operations or security engineering roles.

  • Hands-on experience with security technologies such as SIEM, EDR, IDS/IPS, PAM, and vulnerability management tools.

  • Strong understanding of application security, network security, system hardening, and incident response practices.

  • Familiarity with both IT and OT security environments is an advantage.

  • Professional certifications such as OSCP, CREST, CISSP, CISM, or equivalent are beneficial but not mandatory.

  • Ability to manage multiple priorities effectively in a dynamic operational environment.

  • Strong analytical, problem-solving, and communication skills.
