Astronomer

The Back-end Operations Department (BOD) is responsible for the management of science data from ESO’s optical/near-infrared La Silla Paranal Observatory, as part of integrated end-to-end science operations. This includes the scientific and operational development of the ESO Science Archive, the generation of science data products for distribution through it, the collection, verification and archiving of data products from the community, and the scientific oversight of the reduction of ESO data. ESO copes with the increasing volume and complexity of the data generated at its facilities by providing its communities with the appropriate tools to process and calibrate it. These tools are then routinely used to generate processed data for publication in the ESO Science Archive. They are normally developed in close collaboration with the corresponding instrument-building consortia, and are then taken over and further developed by ESO in consultation with the wider community.

You will take a leading role in assessing and improving the science quality of processed ESO data, and in generating suitably processed data for the ESO Science Archive. This includes working on any aspect that impacts the quality of processed data, e.g. frequency and nature of the calibrations, and research and development of suitable science data processing algorithms. This may include prototyping, while the production-grade implementation is the responsibility of software engineers in the ESO matrix structure. Duty travels to the ESO sites in Chile and relevant conferences/workshops are foreseen. As a Faculty Astronomer, you will be expected to balance your operational responsibilities with robust research portfolio contributing to the science community both in ESO and more widely.

Main Duties and Responsibilities:

Enhance the quality of the processing of ESO raw data by:

• Assessing the quality of existing tools and data, both for direct and archival use.
• Exploring ways to enhance such quality, including processing algorithms and/or observing techniques, and/or calibration schemes.
• Prototyping solutions in commonly used programming/scripting languages, chiefly Python.
• Specifying user requirements and user stories for implementation of the chosen solutions by software engineers.

Generate processed data for the ESO Science Archive by:

• Running the ESO pipelines for selected instrument modes to be ingested in the ESO Science Archive.
• Performing quality control on the resulting data streams.
• Following up data quality issues.

As a member of the ESO Astronomy Faculty, you will be encouraged and expected to carry out original research for up to 50% of your time.

Reports to:

The Head of the Science Data Quality Group.

Key Competences and Experience:

Essential Competences and Experience:

• Experience with observations on a wide range of different telescopes and instruments, and the quality control of such observations.
• Hands-on experience with astronomical data processing and algorithms for a wide range of different data types. This includes a good understanding of limitations and trade-offs of methods.
• Experience with the design of data reduction software and pipelines.
• Demonstrable understanding of numerical and statistical methods as applied to astronomical data reduction.
• Excellent understanding of the user community of astronomical data, and of their needs in terms of raw and processed data.
• Strong cooperative skills to interface with other organisational units/teams in a multicultural environment.
• Critical thinking/problem solving skills.

Desirable Competences and Experience:

• Familiarity with ESO data and processing tools, mainly the pipelines and EDPS.
• Familiarity with the ESO Science Archive and other relevant astronomical data repositories/archives.
• Good understanding of software architecture and experience in working with software engineers to provide requirements for astronomical software projects.
• Code prototyping in programming languages widely used in the astronomical community, e.g. Python.
• Familiarity with the most common Python packages relevant to astronomy (astropy, numpy, matplotlib, pandas).
• Experience with the design of graphical user interfaces for astronomy software.
• Experience with relevant Machine Learning algorithms, ideally applied to astronomy.

Qualifications:

• PhD in Astronomy/Astrophysics, Physics or equivalent.
• An established track record of astronomical research and publication.

Language skills:

The position requires an excellent command of written and spoken English.

Remuneration and Contract:

We offer an attractive remuneration package including a competitive salary , comprehensive pension scheme and medical, educational and other social benefits, as well as financial help in relocating your family and support to place your child/children in daycare.
