About the position Senior Solution Architect Cooling

As Senior Solution Architect Cooling you are the technical go-to for the cooling architecture of our data centers. Your focus is on how the whole thermal chain fits together from heat sources in the IT rooms through air and liquid distribution to heat rejection and heat reusage rather than on being the deepest specialist in a single product.

You work closely with our cooling OEMs design partners and contractors answering technical questions challenging proposals where needed and making sure that the cooling design is robust energy-efficient buildable and supports our availability and sustainability targets.

You support Project Managers Site Managers and the Commissioning Manager with clear technical decisions and you are a key point of contact for the customers cooling energy and operations teams.

Typical systems in your scope:

• Room-level cooling concepts (hot/cold aisle containment in-row / in-rack cooling overhead cooling)
• Chilled water plants free cooling and adiabatic / dry cooler systems
• Direct-to-chip and other liquid cooling solutions for high-density IT
• Heat pump systems and integration with district heating / heat reusage partners
• Air handling units (AHUs) CRAH/CRAC units and associated control philosophies
• Cooling distribution systems (pipework valves pumps balancing redundancy concepts)
• Cooling controls monitoring and integration with BMS/DCIM

Areas of responsibility

Cooling architecture and design coordination

• Own and maintain the overall cooling architecture for assigned projects including cooling concepts system topologies and main equipment line-up.
• Translate customer and operational requirements into detailed cooling concepts and performance criteria (e.g. thermal redundancy temperature/humidity ranges density targets).
• Review and comment on OEM and consultant designs with a focus on interfaces resilience controllability maintainability and energy efficiency (PUE / partial PUE).
• Ensure that cooling design choices support required resilience levels (e.g. N1 2N) and operational concepts for different load and climate conditions.

OEM and supplier interaction

• Act as the main day-to-day technical contact for cooling OEMs (chillers AHUs CRAH/CRAC in-row cooling liquid cooling heat pumps dry coolers).
• Review OEM proposals technical datasheets control philosophies and integration documents.
• Coordinate technical questions (RFIs) between OEMs designers contractors and the EcoDataCenter project team.
• Validate vendor solutions against EcoDataCenter standards performance targets and sustainability goals and highlight deviations or optimisation options.

Support to projects and site

• Support Project Managers and Site Managers with clear cooling input to planning phasing and constructability.
• Participate in key design constructability and value engineering reviews bringing an end-to-end cooling perspective.
• Visit site regularly to walk installations verify that the cooling design intent is followed and support resolution of issues.
• Provide practical input on installation sequencing access maintainability and operations impact of design choices.

Support commissioning and operations

• Support the Commissioning Manager and commissioning engineers in defining test scope for cooling systems (integrated system testing partial load testing failure scenarios).
• Interpret commissioning results from a cooling architecture and performance perspective including thermal stability redundancy behaviour and energy performance.
• Clarify design intent during fault-finding and help assess the impact of deviations or changes on thermal performance and availability.
• Provide technical handover briefings to operations teams regarding cooling architecture heat reusage interfaces limitations and key operating principles.

Documentation and standards

• Ensure that key cooling documents (cooling concepts P&IDs control strategies sequence of operations performance assumptions) are up to date and consistent.
• Contribute to standardising cooling concepts design templates and specifications across projects based on lessons learned.
• Keep an overview of applicable standards and best practices for data center cooling liquid cooling and heat reusage.
• Work with internal stakeholders to refine EcoDataCenters cooling and sustainability guidelines over time.

Your profile

You are an experienced cooling or mechanical engineer who understands how a complete data center cooling chain should be put together. You may have worked for an OEM consultant contractor or operator what matters is that you can see the whole picture and explain it in simple terms.

• Have several years of experience working with cooling systems in data centers industrial plants energy plants or similar mission-critical environments.
• Understand how room cooling chilled water/free cooling systems liquid cooling and heat reusage solutions fit together into a coherent architecture.
• Can read and challenge cooling concepts P&IDs control philosophies and layouts and spot gaps or inconsistencies.
• Are comfortable speaking with OEM specialists asking direct questions and pushing back where a solution does not fit the overall architecture or sustainability targets.
• Can translate technical detail into clear recommendations for Project Managers customers and operations.
• Enjoy being involved both in design meetings and on site seeing how solutions work in real life.

As a person you are analytical structured and curious. You like solving problems by talking directly to the people involved and you keep the end goal in mind: a safe robust efficient and operable cooling system that supports EcoDataCenters sustainability ambitions.

Qualifications

• Degree or vocational qualification in mechanical engineering energy engineering HVAC or similar or equivalent experience.
• Solid experience with data center cooling or industrial HVAC systems; experience with free cooling and heat pump / heat reusage solutions is an advantage.
• Practical experience with some of the following: CRAH/CRAC units in-row or in-rack cooling chilled water plants dry/adiabatic coolers pumps valves heat pumps and liquid cooling systems.
• Ability to read and evaluate P&IDs control philosophies performance calculations (e.g. capacity/efficiency across operating conditions) and equipment selection outputs.
• Experience interacting with OEMs or external design partners on technical options deviations and integration topics.
• Advantage if you have worked on data center projects or other high-availability facilities but strong experience from industrial/utility cooling or energy systems is also relevant.
• Good communication skills in English; Swedish is a strong advantage.
• Good knowledge of the Office package; experience with HVAC/cooling design tools energy modelling or CAD/BIM tools is an advantage.
