Opportunity

ThermalWorks LLC is seeking an experienced Quality Assurance Manager to serve as the technical quality authority and liaison across our customer field sites, European contract manufacturer sites and internal quality control function. This is a cross-functional, high-visibility role that sits at the intersection of manufacturing, field service, and quality leadership.

The ideal candidate brings deep hands-on experience with mission-critical mechanical systems — particularly hydronic cooling, chiller platforms, and data center infrastructure — combined with the discipline and communication skills to document findings clearly and present them to leadership. This role is hands-on and will require mechanical knowledge of HVAC systems as well as quality related processes such as 8D problem solving and Six Sigma methodologies. This position is preferably based in Barcelona, but can also be based in Madrid or Bilbao.  This role has a travel requirement of 20-40% depending on where based.

Key Responsibilities

Factory Quality

• Support new and existing production at ThermalWorks manufacturing operations in Europe to identify quality concerns for first article inspections or before production units ship
• Review assembly, wiring, piping, and commissioning documentation against engineering specifications and approved submittals
• Coordinate findings with factory leadership and flag hold conditions requiring resolution prior to release
• Document inspection outcomes and provide written reports to the Director of Quality

Customer Site Quality

• Perform on-site QA/QC inspections at customer data center locations to verify ThermalWorks equipment installation, commissioning, and service work meets required standards
• Work with EU Director of Operations when customer issues arise
• Drive 8D problem solving for technical customer issues and coordinate investigation and corrective actions with TW Engineering and Operations personnel
• Create customer facing reports such as Root Cause Analysis, Plan of Corrective Actions and Technical Bulletins
• Generate structured inspection reports for each site visit, documenting findings, nonconformances, corrective actions required, and status of resolution

Quality Control Meetings & Reporting

• Participate in internal QC meetings as the field and factory intelligence source, presenting findings and trends to quality and service leadership
• Maintain a running log of open quality items across factory and field, tracking status through closure
• Collaborate with the tech support group to surface recurring field issues that may indicate systemic quality or design concerns
• Support the development and refinement of inspection checklists, MOPs, SOPs, and QA/QC documentation standards

Education and Experience

Required

• 7+ years of hands-on experience in HVAC/mechanical systems or industrial equipment manufacturing
• 4+ years of experience in a Quality position (engineer, supervisor, manager)
• Demonstrated QA/QC experience on construction, commissioning, or service projects in data center or critical infrastructure environments
• Ability to read and interpret engineering drawings, submittals, MOPs, SOPs, and EAPs
• Strong written documentation skills — inspection reports, nonconformance logs, and findings summaries must be clear and actionable
• Willingness and ability to travel to factory and field sites on a regular basis
• Proficiency with BAS/BMS platforms for system verification during site inspections
• Fluency in Spanish

Preferred

• Experience with commercial or mission-critical HVAC/mechanical systems including chillers, hydronic loops, cooling towers, and associated controls
• Experience with Turbocor centrifugal chiller platforms
• Familiarity with dry cooler or adiabatic cooling systems
• Prior experience presenting quality findings to management-level audiences
• Background in instructor-level training or technical mentorship
• Experience reviewing RFIs and equipment submittals
• Fluency in Catalan

This position is structured for a senior technical professional who wants more than a wrench and a work order. You will be the quality intelligence function for ThermalWorks — the person who sees our product built, sees it in the field, and has a seat at the table where quality decisions get made. Your findings carry weight. Your reports go to leadership. Your site visits carry the authority of the Quality Control function.

ThermalWorks is a fast-growing manufacturer of adaptive dry cooling systems for hyperscale data center applications, operating within a vertically integrated infrastructure platform. This is a ground-floor opportunity to build a quality function that scales with the business.
