Perguntas frequentes da vaga

What are the main missions and responsibilities of this role?

In this role, your primary mission is to assist the Sustainable Solutions team in identifying and catalyzing decarbonization technologies that can be scaled across the portfolio. You will be responsible for mapping out emerging themes in clean energy and water, such as hydrogen, advanced geothermal, and cooling efficiency, while gathering data to support investment decisions. Beyond research, you will perform technoeconomic analyses to determine the commercial viability of new innovations. This includes monitoring regulatory shifts and policy developments that might impact the adoption of low-carbon fuels in sectors like maritime and aviation, ensuring that the team’s strategy remains ahead of global market trends. Supporting the broader ecosystem is also key. You will help validate problem statements by engaging with internal stakeholders and preparing materials that translate complex technical data into actionable investment insights for senior decision-makers within the Sustainability Group.

Key learning opportunities for this job

Interns at Temasek gain unparalleled exposure to the frontiers of climate tech. You will learn how to evaluate early-stage and growth-stage technologies—such as nuclear fusion or carbon capture—from both a technical feasibility and a commercial investment standpoint. This bridge between engineering and finance is a rare and highly valued skill set. You will also develop a deep understanding of global ESG frameworks and how a multi-billion dollar investment house operationalizes its net-zero commitments. Through your work on specific clean energy sectors, you will gain technical expertise in hydrogen economies, biofuel supply chains, and industrial electrification strategies. Furthermore, the role provides mentorship from seasoned professionals in sustainability and finance. You will sharpen your professional communication skills by learning how to present findings to sophisticated stakeholders and how to navigate the complexities of a global institutional investor environment.

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

The ideal candidate is currently pursuing a degree in Science, Engineering, Business, or Finance, with a genuine obsession for solving the climate crisis. We look for individuals who don't just know 'what' a technology is, but want to understand 'how' it becomes commercially viable and scalable. Technical literacy is essential. You should have some familiarity with financial or technoeconomic modeling and be comfortable digging into white papers or market reports to extract specific data. A strong work ethic and the ability to work independently in a fast-paced, high-stakes environment are non-negotiable traits for success here. Soft skills are equally important. Because you will be interacting with a small, nimble team, we value candidates who are proactive and creative in their approach to problem-solving. Strong written and oral communication skills are necessary to explain complex topics clearly and persuasively.

Advice to stand out and make a successful application

To stand out, your one-page cover letter must go beyond your GPA. Address the specific sectors mentioned in the job description—like maritime biofuels or geothermal energy—and demonstrate that you have a point of view on their current challenges or potential. Show that you have done your homework on Temasek's 2025 Sustainability Report. Be specific about your technical contributions in previous projects. If you have built a model, conducted a lab study, or analyzed a carbon market before, explain the analytical methodology you used. Temasek values precision and evidence-based thinking, so showcase your ability to handle data-heavy assignments with rigour. Lastly, clearly articulate why you want to work within an investment-led sustainability group specifically. Demonstrating that you understand how capital can be a lever for environmental change will signal that your motivations are perfectly aligned with the team’s mandate.

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

Your work will be laser-focused on the 'E' in ESG, specifically regarding climate mitigation and resource efficiency. You will be directly supporting the firm's goal to reach a net-zero portfolio by 2050, focusing on the technology sectors that have the most significant impact on total emissions. This includes looking at Sustainable Living trends and how the portfolio can adapt to a resource-constrained world. Projects may involve exploring water consumption technologies or identifying innovations that improve energy efficiency in data centres, which are critical components of a modern, low-carbon economy. You will essentially be helping the firm determine which technological pathways offer the best risk-adjusted returns while delivering the carbon reduction needed to meet institutional targets. Your focus is where sustainability meets commercial viability.

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

One of the primary challenges is the complexity and uncertainty of the technologies youจะ be analyzing. Many of the solutions—like fusion energy or e-fuels—are not yet fully commercialized, requiring you to make logical inferences based on fragmented data and evolving regulatory landscapes. You will also need to balance technical depth with commercial brevity. Converting a 50-page technical paper into a three-slide executive summary that highlights financial risks and opportunities is a difficult skill to master. You must learn to identify what truly matters to an investor versus what is just scientifically interesting. Lastly, the pace of a global investment firm can be intense. You will need to manage multiple workstreams simultaneously and adapt quickly when priorities shift based on new market developments or investment committee needs.

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

A typical day might start with a deep-dive research session into a specific technology sector, such as the current state of green hydrogen electrolyzers in Europe. You would spend time gathering data on cost curves, policy incentives, and key market players to update the team's internal knowledge base. In the afternoon, you might join a stakeholder meeting where members of the Investment Group discuss a potential project or portfolio company engagement. Your role would be to listen for technical gaps and take notes on how the Sustainable Solutions team can provide value-added insights to that specific transaction. The end of the day usually involves synthesizing your findings. This could mean updating a technoeconomic model to reflect new data or drafting a summary for a team briefing. The workflow is highly collaborative, with frequent check-ins to ensure your research is aligned with the latest strategic priorities.

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

While this is an internship, it is a high-visibility role within the Sustainability Group of a world-renowned institution. Success here builds a powerful network of contacts across both the financial services industry and the global climate-tech ecosystem. For those who excel, the experience serves as a springboard into roles in Sustainable Finance, ESG Consulting, or Venture Capital. You will have developed a specialized 'edge' by understanding how a major asset owner evaluates climate risk and opportunity, which is one of the most in-demand skill sets in today's job market. Internal growth is also possible in terms of responsibility. High-performing interns are often given the chance to lead independent research projects or take a more active role in stakeholder presentations, providing a clear path to demonstrating professional maturity and leadership potential.

The main stakeholders you might be interacting with

You will primarily interact with the Sustainable Solutions team, a group of specialists driving decarbonization strategy. You will also collaborate with the wider Sustainability Group, including teams focused on ESG Integration and the Ecosperity platform, to ensure a unified approach to the firm's mission. Externally, you may have the opportunity to engage with portfolio company representatives to understand their operational challenges or with technology providers to learn about their innovative solutions. These interactions are focused on validating the real-world applicability of the technologies you are researching. Internally, you might also interface with colleagues in the Investment Group and Financial teams. The nature of these interactions is often consultative: you provide the sustainability and technical context that helps them better understand the long-term resilience and value of potential or existing investments.
