Arbetsbeskrivning

EcoDataCenter is looking for a driven Senior Solution Architect – Cooling who wants to be part of a unique growth journey and help ensure a sustainable infrastructure for society's digitalization.

EcoDataCenter has been named the world's most sustainable data center. With innovative design, circular energy solutions and world-leading technology, we are building the data center of the future – where digitalization and sustainability go hand in hand.

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.

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. N+1, 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.

Your profile

• 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.

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.
