Senior Mechanical Engineer

CloudHQ is seeking a Senior Mechanical Engineer to lead the design, planning, execution, and delivery of advanced mechanical systems for our developer‑led hyperscale data center projects across Europe. Role Overview

The Senior Mechanical Engineer will be responsible for ensuring on‑time, within‑budget, and compliant delivery of mechanical infrastructure—HVAC, cooling, fire suppression, and thermal load management—while providing technical leadership and project management across all project phases.

Key Responsibilities Technical Leadership & Mechanical Design

• Serve as the subject matter expert for design and delivery of mechanical systems meeting reliability, scalability, and energy efficiency goals in hyperscale environments.
• Review detailed engineering specifications and calculations for HVAC, chilled water networks, air handling units, cooling towers, and fire suppression systems, ensuring compliance with regulatory standards.
• Optimize thermodynamic efficiencies and fluid dynamics across mechanical systems to achieve maximum performance and minimize operating costs.
• Review CFD modelling software to simulate airflow dynamics, thermal load distribution, and cooling efficiency, identifying potential hotspots and operational risks.
• Design redundant systems to support continuous operations during peak loads and maintenance windows.

Project Management & Lifecycle Oversight

• Lead mechanical scopes across all phases of development, including early‑stage development, design reviews, and tendering.
• Collaborate with development teams during pre‑construction planning, providing input on master plans, feasibility studies, and design risk mitigation.
• Manage mechanical system integration during construction, acting as the primary liaison between contractors, consultants, and the internal project team.

Compliance & Sustainability Standards

• Ensure all designs comply with European building codes, ASHRAE standards (e.g., TC9.9), and ISO directives.
• Incorporate energy optimization technologies and carbon reduction strategies into designs, meeting enterprise sustainability objectives and achieving optimal PUE targets.
• Monitor adherence to environmental regulations, including waste management, material use, and emissions minimization.

Stakeholder Collaboration & Integration

• Partner with structural and electrical engineers to ensure seamless integration of mechanical systems with building designs and other infrastructure.
• Collaborate with tenant teams to address unique mechanical requirements, tailoring cooling and airflow solutions for their workloads.
• Build and maintain strong relationships with contractors, vendors, and consultants, ensuring project milestones and performance deliverables are consistently met.
• Lead design team meetings, presenting technical insights and ensuring actionable outcomes for mechanical scopes.
• Research emerging industry innovations, including liquid cooling, IoT‑controlled sensor technologies, and AI‑driven predictive maintenance tools, integrating them into CloudHQ projects where feasible.
• Develop and implement modular mechanical solutions, leveraging prefabrication strategies to reduce construction timelines and costs.
• Introduce advanced monitoring systems to enable operational visibility and real‑time performance tuning across mechanical systems.

Skills & Experience Technical Expertise

• Expertise in designing and delivering mechanical systems for data centers, including HVAC, cooling infrastructure, fire suppression systems, and air distribution networks such as AHUs and pressurized systems.
• Advanced knowledge of thermodynamics, fluid mechanics, and heat rejection strategies for large‑scale mission‑critical facilities.
• Proficiency in mechanical system modelling and software tools, including AutoCAD, Revit, and BIM platforms for mechanical design; CFD modelling software (e.g., ANSYS or OpenFOAM); and energy modelling systems for efficiency analysis and reporting.

Regulatory Knowledge

• Comprehensive understanding of EU environmental standards, EN & ASHRAE standards, ISO certifications, and local building codes for designing mechanical systems.
• Familiarity with sustainability frameworks and technologies for optimized performance.

Project Management Skills

• Proven ability to handle complex mechanical scopes across multiple simultaneous projects while maintaining strict adherence to schedules and budgets.
• Skilled in generating detailed documentation, reports, and technical reviews, ensuring compliance across all stages of development.

Travel Flexibility

Willingness to travel regularly within Europe to project sites and contractor facilities (up to 50% travel based on project needs).

Preferred Qualifications Education

Bachelor’s or Master’s Degree in Mechanical Engineering, or equivalent technical discipline.

Certifications

Professional certifications such as LEED AP, ASHRAE Certification, or CIBSE/IMECHE Membership are highly desirable.

Experience

Minimum 8+ years of technical and project management experience delivering mechanical systems for developer‑led data center projects, industrial facilities, or similar mission‑critical environments.

Languages

Fluency in English (required); fluency in German, French, or other European languages (preferred) to support regional collaboration.

CloudHQ is a company that builds sustainable, high‑performance data centers. The Senior Mechanical Engineer will work at the intersection of innovation, technology, and engineering excellence, helping create the digital infrastructure of the future.
