About Us

We are the independent expert in assurance and risk management. Driven by our purpose, to safeguard life, property, and the environment, we empower our customers and their stakeholders with facts and reliable insights so that critical decisions can be made with confidence. As a trusted voice for many of the world’s most successful organizations, we use our knowledge to advance safety and performance, set industry benchmarks, and inspire and invent solutions to tackle global transformations.

About The Role

DNV is going through ambitious growth plans within the cyber security domain, building on our strong position in the Nordics and internationally to make a global impact on safeguarding life, property and the environment.

We are now looking for ambitious and driven Senior Industrial Penetration Testers to join our growing Technical Assessments Norway team.

Our team conducts vulnerability assessments and penetration tests, red team operations, Operational Technology (OT) and Industrial Control Systems (ICS) security assessments, as well as technical advisory work for clients operating in critical industries. We also support customers in remediation projects and contribute to network and security architecture design and assessments.

This role offers a unique opportunity to work on challenging assignments across both IT and OT environments, including industrial control systems, maritime control systems, energy infrastructure, oil and gas installations, renewables, utilities and other critical sectors. You will be involved in exciting engagements where technical depth, creativity and curiosity are highly valued.

A key part of this role will be domestic and international travel. You should be motivated by the opportunity to work on‑site with clients from different countries, cultures and industries. Many of our projects require hands‑on testing, assessments and advisory work at customer locations, including industrial sites, vessels, control rooms, production environments and critical infrastructure facilities. You should therefore be comfortable with regular travel, sometimes at short notice, and interested in building experience across international cyber security environments.

You will work alongside experienced specialists in the cyber security field. We aim to provide a fast‑paced career path with strong opportunities to develop your technical competencies rapidly. DNV will invest in your career development through internal competence development plans, certifications, and participation in industry‑leading projects.

You will be based at one of DNV’s premises in Norway, preferably Trondheim or Oslo, although other locations may be considered for the right candidate.

We look forward to having you on the team.

What You Will Do

As part of the Technical Assessments team, you will contribute to projects such as:

• Penetration testing of IT, OT environments, some of which in live operations;
• Testing of networks, applications, infrastructure, and industrial control systems (ICS);
• OT and ICs security assessments in critical infrastructure environments;
• Red team and adversary simulation exercises for our clients;
• On‑site assessments at customer locations in Norway and internationally;
• Preparation of high‑quality technical reports and executive summaries;
• Collaboration with multidisciplinary teams across DNV’s global cyber security organization;
• You will have the opportunity to work on technically exciting OT pen testing engagements involving environments comprised of PLCs, HMIs, SCADA systems, industrial networks, remote access solutions, shore and offshore systems and other safety‑critical infrastructure.

Travel expectations

This role includes a significant international component. Candidates should be prepared for regular travel to customer sites in Norway and abroad. We are looking for candidates who see international travel as an exciting part of the role and who are motivated by the opportunity to gain hands‑on experience in diverse technical environments around the world.
