This internship puts you at the analytical heart of a major vaccine manufacturing site, where you will take ownership of sustainability data. You will spend your time compiling greenhouse gas emissions, tracking resource efficiency, and supporting the internal KPIs that drive the site’s environmental performance. Beyond the spreadsheets, you will contribute to decarbonization projects and help translate complex data into actionable insights for management.

Joining GSK means entering a high-stakes environment where environmental efficiency translates directly into global health impact. You will help bridge the gap between heavy industrial manufacturing and corporate ESG targets, ensuring that the production of life-saving medicines occurs within the planet’s boundaries. This role is a unique chance to see how decarbonization strategies are implemented in a strictly regulated biopharma setting.

This suits someone who possesses a strong analytical mindset and a genuine fascination with how large-scale industrial operations can be optimized for a greener future.

Job FAQs

What are the main missions and responsibilities of this role?

The core of this role involves overseeing sustainability data integrity for a major manufacturing site. You will be responsible for collecting and analyzing critical metrics such as energy consumption, water usage, and waste generation. This administrative and analytical foundation allows you to support monthly reporting cycles and track performance against key sustainability KPIs. Beyond data entry, you will assist in identifying resource efficiency opportunities. This includes participating in site-specific projects focused on waste management and energy conservation. You will also prepare official documentation for environmental audits, ensuring the site remains in compliance with both internal GSK standards and local regulations. Furthermore, you will play a role in internal communication and engagement. This involves creating presentation materials for stakeholders and supporting campaigns designed to increase environmental awareness among the local workforce.

Key learning opportunities for this job

Candidates will gain deep technical exposure to ESG reporting frameworks and carbon accounting methodologies within a complex industrial context. You will learn how a global pharmaceutical giant tracks its Scope 1 and 2 emissions and how these metrics influence corporate-level decision-making. The internship provides a unique window into biotechnology manufacturing processes and the specific environmental challenges they pose. You will develop a practical understanding of Environmental Management Systems like ISO 14001 and see how global sustainability strategies are localized in an ASEAN context. Soft skill development is also a priority, with opportunities to enhance data visualization skills using Power BI and to learn how to communicate technical environmental data to non-expert site leaders and procurement teams.

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

The ideal candidate is an undergraduate student in Singapore with a background in Environmental Science or Engineering. You should have a high level of comfort with quantitative data and be proficient in Microsoft Excel for complex analysis. Knowledge of carbon accounting principles or life cycle assessment is a significant advantage. We look for individuals who are self-starters with a high degree of digital fluency. Since you will be interacting with various departments, strong interpersonal skills and the ability to explain sustainability concepts to engineers and operations staff are essential. Previous experience with data visualization tools or an understanding of GxP regulations in a laboratory or manufacturing environment will make your profile particularly compelling to the hiring team.

Advice to stand out and make a successful application

To stand out, move beyond just listing your coursework and highlight any specific experience with data auditing or environmental projects. If you have used Power BI or advanced Excel functions to solve a problem in a previous project, mention it clearly as this role is highly analytical. Show that you have researched GSK's specific sustainability goals, such as their targets for carbon neutrality or water stewardship. Mentioning how your skills can help the Tuas site contribute to these global milestones will demonstrate a level of commercial awareness that most interns lack. Finally, emphasize your detail-oriented nature. In a pharmaceutical setting, data integrity is paramount, so showing that you understand the importance of accuracy in environmental reporting will build trust with the recruiters.

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

This role is deeply embedded in the operational decarbonization of GSK's footprint. The primary focus will be on the site's environmental footprint, specifically reducing the energy and water intensity required to manufacture vaccines. You will likely spend significant time on waste hierarchy management, looking for ways to divert manufacturing waste from landfills or incineration. There is also a strong governance component, as you support the site's alignment with GSK's global ESG reporting requirements. Additionally, the role touches on employee-led environmental action. You will help foster a culture where sustainability is part of the site's operational excellence, bridging the gap between high-level corporate strategy and the daily habits of the manufacturing team.

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

A primary challenge will be navigating the complexity of manufacturing data. In a large site, data is often siloed, and you may find it difficult to consolidate information from different engineering and facilities departments into a single, cohesive report. Another challenge is balancing sustainability goals with strict GxP regulations. In pharma, safety and quality always come first; finding ways to improve efficiency without compromising the sterile environment or regulatory compliance requires creative thinking and a deep understanding of operational constraints. Finally, you may face the hurdle of driving behavioral change. Encouraging busy operations staff to prioritize new sustainability initiatives or data collection tasks amidst their production targets can be a lesson in soft influence and persistence.

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

A typical morning might start with validating utility data from the previous month, ensuring there are no anomalies in the energy or water consumption figures. You might then meet with the EHS team to review the requirements for an upcoming environmental audit. Afternoons are often dedicated to project-based work. This could involve researching industry best practices for solvent recovery or creating a dashboard in Power BI to visualize waste trends. You might also find yourself on the manufacturing floor observing a process to identify potential resource leaks. The day often ends with collaborative communication tasks, such as drafting an internal newsletter update on the site's carbon reduction progress or updating documentation for the global sustainability team in London.

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

While this is a time-bound internship, it serves as a high-visibility entry point into the biopharma sector. Successful interns are often well-positioned for GSK’s Future Leaders Program or other junior environmental roles within the company's global network. You will build a professional network of site leaders and EHS experts. This exposure is invaluable for someone looking to specialize in industrial sustainability, providing the 'shop floor' experience that is often missing from purely corporate ESG roles. The skills gained here in carbon accounting and regulatory compliance are in extreme demand across the Singaporean economy, transforming you into a highly sought-after professional for any manufacturing-heavy industry.

The main stakeholders you might be interacting with

You will interact daily with the Engineering and Facilities teams, as they are the primary owners of the equipment and systems that generate environmental data. Their cooperation is essential for any efficiency project. Another key group consists of EHS (Environment, Health, and Safety) Managers. They will provide the framework for your work and ensure that your sustainability initiatives align with safety and health protocols. You will also occasionally report to Site Leadership regarding KPI progress. External stakeholders may include sustainability consultants or auditors, where you will assist in providing the necessary data evidence. Internally, you will also collaborate with Procurement to understand the sustainability profile of the goods entering the site.
