As a technical lead within the Stewardship division, you will spearhead the rollout of ISO 50001 across European sites and oversee the integrity of the energy management system. Your daily focus involves conducting deep-dive assessments to identify efficiency gains, monitoring consumption patterns, and ensuring complex chemical production processes align with evolving environmental standards. You will bridge the gap between technical engineering and regulatory reporting to keep operations optimized and compliant.

Working for a global chemical leader means your energy-saving initiatives have a massive scale. By focusing on decarbonization and technical defossilization, this role directly contributes to the industry’s green transition and ensures that high-impact manufacturing remains viable in a low-carbon economy. It is a rare chance to apply hardcore engineering principles to achieve tangible emissions reductions across a multi-site industrial landscape.

This suits someone who possesses a master’s degree in engineering and at least three years of experience navigating the intersection of chemical production and energy law. You should thrive on data-driven problem solving and feel comfortable presenting technical compliance strategies to senior leadership.

Job-FAQs

What are the main missions and responsibilities of this role?

The core of this role involves the implementation and maintenance of the ISO 50001 energy management system across various European locations. You will act as a technical authority, conducting assessments to identify energy efficiency and climate protection potentials, specifically looking at steam and electricity consumption. Beyond technical auditing, you are responsible for regulatory compliance regarding the Energy Efficiency Act (EnEfG), CSRD, and EU ETS. This includes the preparation of detailed sustainability reports and the interpretation of new legal requirements to keep the company's Stewardship programs at the cutting edge.

Key learning opportunities for this job

Candidates will gain profound exposure to the complex regulatory landscape of the European Green Deal, specifically mastering the nuances of the EU Emissions Trading System (ETS) and Corporate Sustainability Reporting Directive (CSRD). This role offers a deep dive into the technicalities of defossilization within a high-output chemical environment. Furthermore, you will refine your skills in Integrated Management Systems (IMS) by working across EHS and energy standards. The position provides a unique platform to learn how global chemical giants translate broad ESG goals into granular, site-specific engineering projects.

How does the ideal candidate look like (experience, skills)?

The ideal candidate holds a Master's degree in Environmental, Energy, or Chemical Engineering and brings 3 to 5 years of professional experience in production or energy management. You must have a solid grasp of ISO 14001 and ISO 50001 frameworks and be comfortable with the high-stakes auditing environments of the chemical industry. Analytical precision is a must, paired with the communication skills required to navigate interactions with external stakeholders and upper management. Fluency in both German and English is essential for coordinating with European sites and international leadership teams.

Advice to stand out and make a successful application

To stand out, highlight specific examples where you successfully identified energy savings or led a site through a complex certification process. Demonstrating a 'bridge-builder' mentality—showing you can speak both the language of the plant engineer and the legal compliance officer—will be highly valued by the hiring team. Given the technical nature of Celanese’s products, any prior experience with Six Sigma methodologies or complex thermodynamic processes should be prominently featured in your application to prove you can handle the scale of their operations.

What aspects of the company's sustainability is this role likely to focus on?

The role is heavily weighted toward operational decarbonization and resource efficiency. You will be the primary driver for lowering the carbon footprint of production facilities, focusing on how energy inputs like steam and electricity can be optimized or replaced with greener alternatives. There is also a significant focus on governance and transparency. By managing the data for CSRD and energy reporting, you ensure that the company’s sustainability claims are backed by rigorous, auditable technical data, which is crucial for maintaining the firm’s social license to operate.

What are the main challenges someone in this role might face?

One of the primary hurdles will be standardizing energy management across different European sites, each with its own local operational cultures and specific technical constraints. Navigating the rapidly shifting European energy regulations while maintaining production targets requires high flexibility and resilience. Additionally, translating complex engineering data into actionable insights for non-technical stakeholders can be challenging. You must be able to justify the ROI of sustainability projects in a competitive industrial environment where capital expenditure is closely scrutinized.

How could a typical day look like for someone in this position?

A typical day might begin with analyzing real-time energy consumption data from the Frankfurt site to detect any performance deviations. This could be followed by a meeting with plant managers to discuss the technical feasibility of a new heat recovery system or a carbon reduction initiative. In the afternoon, you might switch to regulatory monitoring, reviewing the impact of new EU directives on current reporting cycles, or conducting an internal audit of energy management protocols. The day often concludes with coordinating with European colleagues to ensure cross-border alignment of EHS standards.

What are the opportunities for professional growth and development in this role?

This position offers a clear path toward Global Sustainability Leadership or specialized Stewardship management within the chemical sector. Because you are managing high-visibility compliance and efficiency projects, your impact is easily measured and recognized by senior executives. There are also opportunities for lateral moves into EHS leadership or strategic operational roles, as the expertise gained in energy management is increasingly critical for the long-term strategic planning of large-scale manufacturing firms.

The main stakeholders you might be interacting with

You will regularly interface with Site Managers and Plant Engineers to implement energy-saving measures on the ground. These relationships are critical for ensuring that sustainability goals do not conflict with production efficiency. Externally, you will represent Celanese before regulatory bodies and auditors. Internally, you will report to and advise senior management and global Stewardship teams, providing the data needed to shape the company's overarching ESG strategy.
