Job description

About the job

At mnemonic, we help our customers make their systems and services more resilient to cyberattacks. Sometimes that means building something that doesn't exist yet.

As a Secure Development and DevSecOps Consultant, you will develop niche, customer-specific solutions that solve real security challenges. You will work separately from our in-house product development group, but in close cooperation with them, combining the speed and flexibility of consultancy with the depth of a product organisation.

Examples of solutions in this space include Argus Network Isolator, which lets operators instantly isolate or restrict access to critical IT and OT installations, and Argus Gatekeeper, which provides secure, monitored remote access for vendors and partners into sensitive OT and IoT environments.

You will join a small, close-knit team in a dedicated service area within MSI Cloud & Development. Together, we work on everything from development to customer projects, so you will have real influence on what we build and how we build it. We believe that diverse perspectives and experiences make teams stronger and help us build better, more secure solutions. We encourage talent from all backgrounds to consider joining our team.

Python is our main working language, and security is at the heart of everything we build.

You will be working with

You will get the opportunity to work with a wide range of tasks, which may include:

• Designing, developing and maintaining customer-specific solutions, primarily in Python.

• Building and integrating with APIs, including those of leading security and network vendors.

• Owning the full lifecycle of your projects, from first commit to production and ongoing maintenance.

• Building, maintaining and improving CI/CD pipelines in GitHub Actions, GitLab CI and similar platforms.

• Building and running containerised applications with Docker, Podman and related tooling.

• Implementing DevSecOps practices such as SAST, dependency and container scanning, secrets management and secure pipeline design.

• Exploring and applying AI and agentic tooling to how we develop and deliver solutions.

• Cooperating with our in-house development teams, security architects and customers.

What you will bring

We are looking for someone that:

• Has at least 2-3 years of relevant, hands-on development experience, with Python as a strong working language.

• Has built and maintained a project over time, and understands what it takes to keep code healthy beyond the first release.

• Has experience developing, consuming and integrating with APIs.

• Builds and uses containers as a natural part of their workflow.

• Uses Git as a natural part of everyday development.

• Has experience using, maintaining or building CI/CD pipelines, and is familiar with concepts such as runners, protected environments and branch protection.

• Has a genuine interest in security. Previous experience with secure development is not required, but it is highly beneficial, and security will be a large part of the job.

• Is able to obtain a security clearance, as some of our customers and projects require this.

• Speaks and writes Norwegian, as well as English.

Nice to have

• Experience developing with AI and agentic tools. Note that this complements, and does not replace, first-hand development experience.

• Experience with SAST, SCA or other security tooling in development pipelines.

• Familiarity with secure coding principles, threat modelling or frameworks such as OWASP SAMM or SLSA.

• Experience with network security, OT environments or infrastructure-as-code.

• Relevant certifications within cloud, development or security.

What we can offer

• An informal and pleasant working environment that provides opportunities for growth, influence and variations in tasks

• Competitive salary, share program and bonus scheme that promotes a long-term employment outlook, including attractive pension and insurance coverage

• Opportunities for relevant professional training (courses) and conferences

• We place a strong emphasis on workplace well-being and teambuilding through social activities, events and trips with colleagues. In addition, we have an inclusive environment that promotes work-life balance and accommodates to families

• Our offices are centrally located in Solli plass in Oslo, with work from home opportunities

• A workplace that is ranked as one of the best in Europe. In Norway we have been amongst the top 10 workplaces for 10 years in a row.
