Senior and Junior Energy Modeler/Researcher

Vacancy 19/2019 - The IIASA Energy Program (ENE) is looking to recruit one Senior and one Junior Energy Modeler/Researcher to join a team analyzing a wide range of issues related to energy sector transitions in the context of climate change and broader sustainable development challenges.

Main Job Duties:

The successful candidates will join a team analyzing a wide range of issues related to energy sector transitions in the context of climate change and broader sustainable development challenges. The research of successful candidates will, in particular, focus on modeling energy services and their linkage to the energy system and beyond with the open source MESSAGEix model and its extensions. The purpose of the research is to inform international policy efforts, such as those related to the Paris Agreement or the Sustainable Development ­Goals (SDGs), and assess synergies and trade-offs between them. Successful applicants, among other things, are expected to contribute to ongoing projects at IIASA, for example CD-LINKS or the Low Energy Demand (LED) study.

Applicants must be prepared to process and manage large datasets, including technology and consumer survey data, become proficient with a complex integrated assessment model, and analyze results of modeling studies. In addition, the selected candidates will be  expected to contribute to the development of new modeling approaches. For senior applicants, reflecting critically and independently about their research as well as taking over responsibility for research activities is expected. 

Our Requirements:

Candidates for the junior position should have a Master’s degree (or equivalent) in economics, engineering, environmental or basic sciences (e.g., mathematics, physics).

For the senior position, a PhD (or equivalent) in economics, engineering, environmental or basic science (e.g., mathematics, physics) and at least five years of experience in energy systems modeling are required.

The expectation is that successful candidates will contribute to ongoing and future analysis of energy and climate objectives within the context of broader sustainable development issues and specifically, the Sustainable Development Goals (SGDs). Sustainable development objectives related to a wide spectrum of SDGs are of relevance, including equitable access to modern energy services, provision of safe water and access to sanitation and sustainable consumption patterns and the link to the circular economy. In addition, senior candidates are expected to take over responsibility for research activities and contribute to developing proposals for new research projects.

Experience with GAMS or similar mathematical programming tools for quantitative modeling and programming skills in R and/or Python are highly desirable as the ENE program is developing its modeling tools using these programming languages (cf. MESSAGEix documentation). In addition, specific domain knowledge of the buildings, industry or transport sector, industrial ecology methods (e.g. material flow and lifecycle analysis), and skills relevant for modeling consumer decisions or computable general equilibrium (CGE) modeling are highly welcome.

IIASA offers a highly interdisciplinary workplace, with strong ties to a world-wide network of research institutions engaged in environmental and energy research and, in particular, on the analysis of climate change and broader sustainable development issues. Furthermore, the selected candidates will interact with researchers from a diverse set of countries requiring intercultural communication skills.

Appointment Terms: 

Successful candidates are expected to begin their assignments as soon as possible, but no later than September 2019. The initial appointment period will be one year, but the goal is a longer-term appointment.

Duties will be carried out at the IIASA premises in Laxenburg, Austria.

IIASA offers a competitive compensation and benefits package (home leave, moving allowances, educational grants for children of school age, and five weeks’ annual vacation). IIASA salaries are exempt from taxation in the host country of Austria but subject to the principle of income aggregation. Gross salaries are competitive and will be based on qualification and experience. 

IIASA is committed to a working environment that promotes equality, diversity, tolerance and inclusion within its workforce, and encourages qualified candidates from all religious, ethnic and social backgrounds to apply. In the case that candidates are equally qualified, preference will be given to applicants who are nationals of IIASA member countries.

Application Requirements:

Applicants for the junior position should send a detailed curriculum vitae, a letter of application describing their motivation and fit to the position, and at least one letter of recommendation.

Applicants to the senior position should send the same materials plus a statement of research interests.

Please mention the names and contact details of three reference givers in your application.

Application materials should be sent electronically to:

We shall continue to accept applications until the position has been filled.

About Vienna:

In 2019, Vienna ranked as the city with the world’s best quality of living for the 10th time, according to the Mercer Quality of Living Survey and the Economist. Vienna is a beautiful, historical yet modern city, located in the heart of Europe, close to the Alps and to major cities like Munich, Zurich, Prague, and Budapest. Being famous for its concert venues, opera houses, theaters, museums, and coffee shops, Vienna also provides opportunities for great outdoor activities, such as sailing on Lake Neusiedl, ice skating, biking and hiking in the Viennese woods and the nearby Alps. Moreover, the city has a wide range of excellent restaurants, bars, wineries, cinemas, clubs, libraries, galleries, and art collections. The Vienna area is also an exceptional and highly international research environment.
