Junior Climate Data Scientist

Department

Turn climate data into investment insight.   Research, develop and   maintain   robust climate analytics that help investment professionals assess how companies and portfolios are positioned for the transition to a low-carbon economy.

The opportunity

Robeco is looking for a Junior Climate Data Scientist to strengthen the connection between climate research, data   science   and investment practice.   Robeco has been at the forefront of sustainable investing for more than 25 years, combining rigorous research with proprietary sustainability frameworks and active ownership. This long-standing   expertise   is embedded across its investment processes and continues to shape   new approaches   to climate,   nature   and sustainable development.

As a Junior Climate Data Scientist, you will sit within the Investments Data Science team and work in close collaboration with the SI Center of Expertise. This cross-disciplinary environment brings together quantitative researchers, portfolio managers, sustainability specialists, and data engineers ,   all focused on translating complex sustainability and climate data into actionable investment intelligence.

Position & Requirements

In this   role , you will research,   develop   and   maintain   climate - investing   insights.   You will   evaluate   climate-related datasets, translate investment questions into quantitative analyses ,   and turn research prototypes into   reliable   tools,   metrics   and processes.   The   work   involves   complex   data and evolving   methodologies , so your outputs must   be both analytically   robust   and   practical for   investors.

What you will do

- Research, develop,   validate ,   and continuously improve Robeco’s proprietary climate metrics and quantitative models, translating emerging climate-investment questions into differentiated intellectual property. This includes areas such as GHG emissions estimation, temperature alignment, transition risk   scoring,   and climate scenario analysis.

- Stay current with developments in climate science,   sustainable investment   research,   regulation,   and data innovation.   Assess their relevance for Robeco’s investment   approach and   use relevant findings to improve existing models or identify opportunities for new proprietary analytics.

- Identify , assess, and analyze climate and sustainability data from a wide range of sources, including carbon   emission   databases, corporate disclosures, climate target registries, and third-party ESG data providers.

- Evaluate data quality and address gaps through statistical estimation and imputation, ensuring that the data underlying investment decisions   are   reliable and well-documented.

- Write clean, reproducible Python code that can be   maintained   and extended by the broader team, with consistent attention to version control, testing, and documentation.

- Build tools, dashboards, and reports that communicate climate insights to portfolio managers, sustainability specialists, and other stakeholders ,   including colleagues without a data science background.

- Collaborate with portfolio management teams to analyze the impact of climate-related investment constraints and   objectives   on portfolio composition.

- Stay current with developments in climate science, sustainability regulation, and data innovation, and bring relevant insights back to the team.

Examples of questions you may work on

- How can reported emissions, estimated emissions and company targets be combined to form a forward-looking view of   decarbonisation ?

- Which climate indicators provide useful information beyond a company’s current carbon footprint?

- How do climate   objectives   or portfolio constraints affect investment exposures,   risk   and diversification?

- Where can automation or carefully governed AI reduce manual work without weakening analytical control?

What you bring

- A master’s degree in a quantitative field such as econometrics, mathematics, data science, computer science, engineering, physics, environmental   science   or a related discipline.

- Up to approximately three years of relevant professional experience. Strong graduates are   particularly   encouraged to apply.

- Strong analytical and programming skills in Python, including experience with the Python data stack such as pandas and NumPy.

- Experience working with structured data and SQL. Familiarity with   PySpark , Databricks, Git, dashboards or web applications is an advantage.

- An interest in climate change, sustainable   investing   and financial markets. Prior   climate-data   or investment experience is helpful, but not essential.

- Care for data quality, methodological consistency, readable   code   and clear documentation.

- The ability to explain complex topics clearly and work effectively with both technical and non-technical colleagues .

- Curiosity, sound judgement,   independence   and a practical mindset. You are comfortable investigating an unfamiliar problem and asking for input when needed.

- Professional   proficiency   in written and spoken English.

Research shows that female candidates only apply if they meet 100% of the requirements, while male candidates already do so at 60%. Are you hesitant about whether you meet all requirements? Please do apply, we’re looking forward to hearing from you.

How we think about AI in this role

AI literacy is part of effective data-science work, but it is not a substitute for subject knowledge or quantitative judgement. We are looking for someone who can select   appropriate tools , formulate good questions, inspect generated code or text   critically   and verify results against reliable sources and tests. Experience with AI coding assistants, large language models or automated document analysis is welcome, but deep AI   specialisation   is not   required .

All applications will be treated with the utmost confidentiality. An assessment and integrity test may be used in the selection procedure.
