Senior Cybersecurity Engineer in Belfast

A global manufacturing and technology business is expanding its cybersecurity capability in Belfast and is hiring a Senior Cybersecurity Engineer to join a small, highly hands-on security engineering team supporting the organisation worldwide. This is a technical, delivery-focused role for someone who enjoys building and improving security controls, taking ownership of tools and platforms, and seeing their work make a direct impact on the organisation's security posture. This is not a SOC or pure incident response role. It is an engineering position focused on designing, deploying, configuring and improving security solutions across a hybrid on-prem and cloud environment.

Responsibilities

• You will join a lean security operations and engineering function responsible for selecting, implementing and maintaining the organisation's core security technologies.
• Deploying, configuring and improving security tools across endpoint, data protection, identity and cloud platforms.
• Identifying control gaps, researching solutions, running proof-of-concepts and leading implementations.
• Reviewing existing security controls and completing the "last mile" of configuration, optimisation and documentation.
• Working closely with architecture and cyber defence teams to ensure tools are properly integrated and operationalised.
• Providing security input into new business and manufacturing initiatives, ensuring controls are designed in from the start.
• Taking ownership of solutions rather than operating in a narrow, siloed function.

Qualifications & Skills

• Strong hands-on experience in cybersecurity engineering or security operations (typically 5+ years).
• Proven experience deploying and configuring security platforms rather than only monitoring or responding to alerts.
• Solid understanding of endpoint security and endpoint management technologies.
• Experience working with data protection and data loss prevention controls.
• Working knowledge of SIEM and security monitoring platforms, including configuration and tuning.
• Good understanding of cloud security concepts within a hybrid environment.
• Experience working with identity and access management in an enterprise setting.
• Ability to work in small teams with a high level of autonomy and responsibility.
• Strong communication skills and the confidence to work directly with technical and non-technical stakeholders.

Nice to Have

• Experience across both on-prem and multi-cloud environments.
• Exposure to security architecture and solution design.
• Industry certifications (CISSP, Security+), though these are not essential.

Who This Role Suits

• A senior, hands-on security engineer who enjoys owning problems end-to-end.
• Someone coming from a less siloed environment where they have worked across multiple security domains.
• A self-starter who looks for gaps and improvements rather than waiting for tasks.
• An engineer who wants to progress towards architecture over time.

Why This Role Stands Out

• You will have real influence and ownership in a small, expert team rather than being one of many specialists.
• Immediate impact, with a clear pipeline of improvements and enhancements to deliver.
• Exposure to both enterprise IT and manufacturing environments, offering a varied technical landscape.
• Clear progression into architecture and broader security leadership roles as the function continues to evolve.

Working Model & Benefits

• Hybrid working: 3 days per week on-site in Belfast.
• Open to UK-based candidates willing to relocate.
• Comprehensive benefits package including healthcare, pension and additional company benefits.
