Senior Mechanical Engineer

Do you have in-depth experience in mechanical installations and want to contribute to the most critical and innovative data center projects of today? As a Senior Mechanical Engineer Data Centers at Deerns, you will work on high-tech, scalable, and energy-efficient facilities that keep the digital world running. You will design the installations that guarantee maximum reliability, sustainability, and continuity, precisely what the data center sector demands.

The Challenge 

As a Senior Mechanical Engineer within our Data Center department, you will be responsible for the design, engineering, and technical coordination of complex mechanical installations. Think of advanced cooling concepts (such as indirect/direct evaporative cooling, liquid cooling, and chiller solutions), air treatment, heat recovery, water and gas systems, and climate-technical infrastructure that must function reliably 24/7.

From the initial concept phase, you will contribute to technical strategies and design choices that align with scalability, energy efficiency, availability standards (Tier III/), and increasingly stringent sustainability goals. You will collaborate closely with other disciplines such as electrical engineering, structural engineering, and security, and monitor the technical integrity and coherence of the overall design. Thanks to your seniority, you will serve as the subject matter point of contact for clients, design teams, and suppliers. You will make adjustments where necessary, mentor junior and medior engineers, and actively contribute to knowledge development within the data center team.
 

Your responsibilities include: 

• Designing mechanical building-related systems, including HVAC (heating, ventilation, and air conditioning), cooling, and other Data Center-specific installations.

• Contributing to the concept and design phase and translating client requirements into feasible and scalable technical solutions.

• Coordinating design activities with other disciplines and monitoring planning, quality, and integrated coherence.

• Being the technical point of contact for clients, partners, suppliers, and internal stakeholders/juniors.

• Mentoring engineers within the project and contributing to knowledge development in the team.

• Supporting tender processes, cost estimations, and quality controls (both design and execution).

What We Work On

We have contributed to the construction of various new data centers in locations such as Milan and Amsterdam. We have provided support in the design of mechanical, electrical, and sanitary installations for the construction. After the design of the mechanical, electrical, and sanitary installations, Deerns supervised the construction site to check the quality of the installations and acted as Commissioning Manager for the main contractor. Deerns also provided support during construction to achieve a Leadership in Energy and Environmental Design (LEED) certification. LEED certification means a building is healthy, highly efficient, and delivers better environmental performance.

The Team 

You will be part of a team of approximately 16 colleagues, within a broader organization where you will have over 750 colleagues across different sectors. The Data Center team is a close-knit group consisting of project managers, consultants, mechanical, and electrical engineers. The culture is open, knowledge-driven, and focused on collaboration and enjoyment of work. Furthermore, you will work in a cohesive, integrated project team where everyone's knowledge and expertise are optimally utilized. This not only ensures strong collaboration but also personal growth. The Data Centers unit primarily works for Colocation providers, banks, and large companies, both in the Netherlands and internationally. This ensures that you work on diverse projects, and no two days are the same. Additionally, you will regularly collaborate with our units in England, Spain, and Brazil, making you part of a strong international network.


This Is You 

• You have at least a completed Bachelor's or Master's degree in Mechanical Engineering, Installation Technology, or a comparable field.

• You have several years of experience (preferably 5+) as a Mechanical Engineer within complex building-related installations; experience with data centers or mission-critical environments is a strong advantage.

• You have experience with multidisciplinary project environments and can collaborate excellently with colleagues from other fields.

• You have excellent command of the Dutch and English languages, both spoken and written.

• You are proficient with MS Office, Revit, BIM360, and relevant calculation and simulation software (such as Vabi, CFD tools, cooling load calculations, etc.).

• You are analytically strong, technically curious, and can effortlessly switch between detail and overall perspective.

• You take responsibility, communicate clearly, and feel at home in a role where technology, quality, and client contact come together.

What We Offer 

• A position of 32-40 hours per week with a corresponding salary. 

• Challenging projects for leading clients in the Netherlands and internationally. 

• A work environment where innovation and sustainability are put into practice daily. 

• Attention to your own development and vitality with ample training and development opportunities, bicycle and sports facilities, flexible working hours, 33 vacation days, and the option to purchase additional days. 

• Hybrid working, with the possibility to work alternately from home and at the office in The Hague. 

• A team where collaboration and collegiality are paramount, and where we interact informally. 

• Sustainability is in our genes. This is reflected, for example, in a mobility policy that prioritizes health and sustainability. Many of our offices are located near public transport hubs, cycling is encouraged, and your travel expenses are reimbursed 100% based on public transport.
