Data Center Sustainability Manager

The Data Center Sustainability Manager is tasked with overseeing environmental initiatives across international data center sites. This involves coordinating energy efficiency programs, monitoring carbon footprints, and supporting technical infrastructure projects covering power distribution, cooling, and facility systems. On the compliance and disclosure front, the role coordinates reporting in line with the Corporate Sustainability Reporting Directive (CSRD), the EU Taxonomy, and the Energy Efficiency Directive (EED). The manager leads the collection, validation, and submission of critical operational metrics such as Power Usage Effectiveness (PUE) and Water Usage Effectiveness (WUE). Additionally, the position bridges technical engineering and commercial functions by contributing sustainability insights during client bids, audits, and presales advisory engagements, as well as maintaining alignment with global engineering guidelines and the European Code of Conduct for Data Centre Energy Efficiency.

Working in this position provides deep exposure to the intersection of massive-scale digital infrastructure and rigorous European Union environmental directives. A professional in this role can expect to sharpen their practical mastery of CSRD reporting architecture, EU Taxonomy alignment, and EED data requirements for digital assets. The candidate will likely expand their engineering knowledge of high-efficiency data center cooling systems, building management systems (BMS), and energy monitoring platforms. Navigating compliance for global infrastructure also offers hands-on familiarity with frameworks such as ISO 50001 and EN 50600 standards.

The ideal candidate combines an engineering or technical facilities background with a strong track record in corporate sustainability and energy management. Practical experience in data center operations, technical project delivery, and carbon accounting methodologies is essential. Fluency in key regulatory regimes, particularly European directives on energy efficiency and ESG disclosures, is expected, alongside expertise in collecting and validating complex utility data. Because this role interfaces with German headquarters and European operational hubs, full bilingual proficiency in both English and German is mandatory.

To stand out, highlight specific accomplishments where you translated energy metrics or regulatory demands into measurable infrastructure improvements. Quantify outcomes around PUE reductions, cooling optimizations, or successful submissions under the EU Code of Conduct. Given the international footprint of Deutsche Telekom, emphasize your cross-border collaboration skills and demonstrate clear confidence communicating complex engineering concepts to business development and presales teams. Explicitly clarify your working fluency in German during technical discussions.

The primary focus is direct decarbonization of Scope 1 and Scope 2 operational emissions from heavy power and cooling consumption across global data halls. This involves identifying innovative thermal management technologies and renewable power strategies. Regulatory and reporting integrity forms a second core pillar. The role ensures that Deutsche Telekom's compute infrastructure withstands third-party scrutiny under emerging EU data center disclosure laws, supporting the company's broader net-zero trajectory and customer supply-chain expectations.

Balancing stringent uptime and performance service level agreements (SLAs) with aggressive power-reduction initiatives is often a demanding compromise in mission-critical facilities. Facilities engineers may occasionally prioritize redundancy over aggressive efficiency adjustments. Another significant obstacle lies in harmonizing disparate legacy data streams across multiple facilities into auditable ESG data pipelines suitable for CSRD compliance. Achieving buy-in across distributed operational teams across borders requires persistent stakeholder diplomacy.

A typical day could begin by reviewing daily power usage and cooling metrics from monitoring systems across key data centers, flagging any unusual variance in efficiency indicators. The morning might proceed with a cross-functional alignment meeting with regional engineering teams to discuss planned retrofits or compliance submissions under the Energy Efficiency Directive. In the afternoon, tasks might shift toward preparing technical responses for a major corporate client's sustainability assessment or consulting with the corporate ESG team on annual carbon accounting validations. The day often closes by evaluating technical vendor proposals for emerging liquid cooling or energy monitoring tools.

Given the accelerating demand for sustainable computing and AI infrastructure, this role occupies a high-visibility vantage point. Success can lead to senior leadership positions within global data center operations, digital infrastructure sustainability, or enterprise ESG strategy. Professionals can also branch into strategic procurement for green energy, sustainable product engineering, or higher-level roles shaping group-wide net-zero technology architecture across the Deutsche Telekom network.

Internal collaboration involves constant contact with data center facilities engineers, site operations teams, and regional infrastructure directors. Frequent alignment is also maintained with the group-level Corporate Sustainability and ESG office to guarantee unified metrics. Externally, the role engages with regulatory auditors, industry standard-setting working groups, and major corporate clients seeking transparency on their outsourced digital footprint. Collaboration with infrastructure equipment vendors and monitoring software providers is also routine.
