Senior BI Developer Cognos

Project overview

Job description

For our end client, the Municipality of Haarlemmermeer, we are looking for a Technical Security Engineer.

As a Technical Security Engineer, you will be responsible for designing, developing, implementing, and securing the technical solution within the AI "sprint" environment. You will work in a multidisciplinary team following an agile methodology and collaborate closely with the Privacy Officer, TISO, product owner, and other specialists.

Your primary focus will be on the development of the AI prototype, technical integrations, and the implementation of appropriate security measures. You will ensure that security-by-design, privacy-by-design, and manageability are integral parts of the solution from day one.

You will contribute to the technical risk analysis, the development of control measures, the DPIA, and the translation of compliance requirements into concrete technical solutions. Structured work, documentation of choices, and recording technical configurations and security measures are essential parts of the assignment. This will result not only in a working solution but also in a prototype that is secure, manageable, and ready for a potential follow-up phase.

Responsibilities

The Technical Security Engineer will be engaged for the duration of the AI "sprint" and the directly related preparation and follow-up activities. The engagement averages 32 to 36 hours per week.

Given the nature, complexity, and short turnaround time of the assignment, a single senior professional is explicitly sought who will be responsible for the technical realization, security, and assurance of the solution throughout the entire assignment. Continuity, speed of action, and knowledge retention are essential.

The assignment consists of three phases:

During the "sprint" week, the Technical Security Engineer is expected to be fully available and physically present at the municipal work location Beukenhorst in Hoofddorp. The intensive collaboration between different disciplines requires direct coordination, rapid decision-making, and joint problem-solving, making remote work unsuitable during this week. Physical presence at the location is also expected during the preparation and follow-up phases, unless an occasional exception is agreed upon.

Job Requirements

As a Technical Security Engineer, you have demonstrable experience in designing, developing, implementing, and managing digital solutions within complex organizations. Additionally, you are familiar with agile working and know how to collaborate effectively in multidisciplinary teams where development, security, privacy, and management converge.

You are capable of translating technical issues into concrete solutions and actively contribute to the risk log, DPIA, technical architecture, and control measures that will be developed during the AI "sprint".

Company Information

Haarlemmermeer is one of the largest municipalities in the Netherlands with 162,000 inhabitants. 18,500 hectares of land, comprising 32 centers, create an area full of exciting contrasts. We have vast landscapes and agricultural land, as well as impressive urban architecture and high-tech multinationals. And of course, Schiphol Airport. We are a young municipality but have a rich history, partly reflected in the Stelling van Amsterdam with its 19th-century pumping stations. Haarlemmermeer is undergoing significant development. It is a dynamic place where people want to live, work, and recreate.

It is green and urban at the same time.

Building Haarlemmermeer and managing our organization requires drive. If you have this, combined with a results-oriented approach, you will fit in well with us. And with our ambition to become one of the best service municipalities in the Netherlands. For this, we need professional people who are engaged with society. We offer you every opportunity for broad development, have attractive employment conditions, and offer a different work environment every day.

The municipal organization is divided into 5 domains. One of the domains, Operations, includes several support clusters that handle support for the entire municipal organization in areas such as housing, procurement, legal affairs, personnel policy, finance, and ICT.

You will work within the future DIGI cluster (Data, Information, and Digital Innovation), in the Data Team. This cluster is established to elevate data-driven working within the municipality to a higher level.

Naturally, this vacancy is open to anyone who recognizes themselves in this.
