Job description

Technical Information Security Officer (TISO)

Cybersecurity is not a checklist. It is a continuous interplay of innovation, emerging threats, and resilience.

At Limina Hacking Company, we help organizations manage digital risks and leverage security as a strategic business enabler. We combine deep technical expertise with a hacker mindset, operating at the intersection of Cloud, Microsoft Security, Identity, Compliance, and Cyber Defense.

Our consultants do more than write recommendations. They implement, optimize, and deliver measurable results. That is why we are looking for a Technical Information Security Officer (TISO) who goes beyond policies and audits.

Someone who understands technical risks, thinks like an attacker, and helps organizations continuously improve their security maturity.

As a TISO, you act as the technical trusted advisor for clients, architects, security engineers, and management teams. You bridge the gap between strategy and technology, translating security objectives into practical and effective measures.

You will provide advise on:

AI governance and responsible AI adoption

Cloud, infrastructure, and application security

Digital workplace and endpoint security

Identity & Access Management (IAM) and Zero Trust

Security architecture and secure-by-design principles

Threat, vulnerability, and exposure management

Security operations, monitoring, and incident response

Risk management, compliance, and regulatory frameworks

Improving organizational cyber resilience and security maturity

You can easily switch between strategic discussions with CISOs and IT Managers and deep technical analyses of topics such as Conditional Access, security configurations, and cloud infrastructures.

Our Offer

Salary between €5.500,- and €8.000,- gross per month (based on a 40-hour work week);

Performance bonus based on commitment and results;

25 vacation days and 8% holiday allowance;

Mobility budget of €750,-;

Company laptop and phone;

Pension plan;

Generous training budget for courses, certifications, and personal development;

Hybrid working model: remote, on-site at customer locations, and from our office;

Access to a strong network of cybersecurity professionals;

Career growth opportunities toward Security Architect, Lead Consultant, or CISO Advisory roles;

Hybrid working and flexibility;

Knowledge sharing days, technical deep dives, and community events.

Key Responsibilities

Support the execution of technical risk assessments within cloud and hybrid environments;

Collaborate with technical teams to identify vulnerabilities and advise on mitigating controls;

Conduct security reviews;

Assess cloud architectures and new IT solutions against security best practices;

Implement and optimize Zero Trust, IAM, and technical security controls;

Perform security design reviews and apply Security by Design principles;

Translate security policies into technical standards and controls;

Support ISO 27001, NEN 7510, BIO, and audit initiatives;

Analyze threats, attack vectors, and penetration testing findings;

Advise on system hardening, monitoring, and detection capabilities;

Support security incident response activities and post-incident analyses;

Work alongside SOC, Red Team, and Blue Team specialists;

Act as the bridge between the CISO function, security governance, and technical implementation.

Your Strengths (required/Preferred)

Bachelor's or Master's degree in Computer Science, Cybersecurity, Information Security, or a related field;

Minimum of five years of experience in cybersecurity or information security;

Experience as a TISO, Security Consultant, Security Engineer, or Security Architect;

Experience working in complex Enterprise environments;

Strong communication skills and proven stakeholder management experience at both technical and executive levels;

You are proficient in Dutch, both spoken and written;

You understand how to apply security frameworks and regulatory requirements, including ISO 27001/27002, NIST, CIS Controls, BIO, NEN 7510, and GDPR, and can translate these into practical security measures that deliver measurable business value.

Certifications

Preferably, you hold one or more relevant certifications, such as:
