Qualification Details

The position as a system developer in software’s primarily purpose is to develop software to support the science of the LSST.  A successful candidate should bring:

  • A Bachelor's degree and at least eight years of relevant experience in scientific programming (if from an industry background), or a PhD in a relevant field and relevant experience in software engineering (if from an academic background)
  • Fluency in developing software with the Python programming language
  • The ability to quickly learn and adapt to new technologies and programming tools
  • Demonstrated experience in designing, developing, testing, and deploying applications
  • Understanding of software development, data management, and modeling, and collaborative development
  • Understanding of all aspects of software development life cycle and quality control practices
  • Ability to define and solve logical problems for highly technical applications
  • Communication skills with both technical and non-technical clients
  • Demonstrated experience leading activities on structured team development projects
  • Ability to select, adapt, and effectively use a variety of programming methods
  • Ability to recognize and recommend needed changes in user and/or operations procedures.

The position requires fluency in spoken and written English to work effectively in a large team of international software developers and researchers.

Experience in working in a scientific environment is desirable, but not essential. Experts in other relevant fields, especially those with artificial intelligence and machine learning backgrounds are also welcome to apply.

In the appointment process, special attention will be given to programming skills, experience in following best practices of collaborative software development, expertise in web app development and/or data management systems. Highly desired experience includes familiarity with HPC systems. Experience in working with large-scale data processing for astronomical surveys is desirable but non-essential.

Responsibilities/Job Description

The successful candidate will spend 50 percent of their time working collaboratively with a large international team of system developer in software preparing the scientific analysis infrastructure for the DESC. During the remaining 50 percent of the time the candidate is expected to support Stockholm researchers in conducting original research on the cosmic large-scale structure or time-domain cosmology, broadly related to testing fundamental physics and cosmology with LSST. A system developer in software at the Oskar Klein Centre will:

  • Design, develop, implement, and maintain the pipeline, workflow, continuous integration, data processing, analysis, and management software for our collaboration infrastructure
  • Troubleshoot and resolve complex technical problems, and review the design of existing systems for optimizing performance, especially on HPC systems
  • Propose, conceptualize, design, implement, and develop solutions for difficult and complex applications independently
  • Work as an integrated member of the DESC Computing Infrastructure team, proactively consulting with the wider collaboration to learn about requirements
  • Develop and apply novel statistical and machine learning techniques, including writing production-level code for analysis of LSST data and precursor datasets.

Specific tasks may include developing web apps for time-domain alert management pipelines, supporting software development via continuous integration and deployment, or building large-scale data management systems and databases.

The position also involves coordinating work with a large international team of developers in different time zones. This may require the successful candidate to accommodate meeting times that allow for the participation of colleagues based on the US west coast in their morning.

About the Project/Department

The Department of Physics is one of the biggest departments within the Faculty of Science and supports a broad range of basic research in experimental and theoretical physics. It has about 250 employees of which 95 are PhD students. Many have been internationally recruited. The Department is part of the AlbaNova University Center, which apart from the Department of Physics houses the Department of Astronomy, the Physics Departments at the Royal Institute of Technology (KTH), and the Nordic Institute for Theoretical Physics (Nordita).

The Department of Physics and Stockholm University is affiliated to Stockholm Dual Career Network (SDCN) that supports expat partners with professional events, career-related advice, and by building a social network in their new hometown,

The Vera C. Rubin Observatory is a next-generation astronomical facility currently under construction in Chile. Rubin’s LSST will be one of the largest and most comprehensive astronomy surveys of its kind, enabling countless astronomical and physics discoveries. To take best advantage of the LSST data, DESC develops new methods for obtaining state-of-the-art, robust cosmology constraints and builds robust, high-throughput software pipelines to simulate, re-process and analyze images and catalogs at LSST scale.

The holder of the employment will work alongside scientists in Stockholm and collaborate internationally with scientists in the DESC. Responsibilities may include understanding various LSST science use cases and then applying software engineering expertise to modify, extend, and update the Rubin data processing pipelines in response to emergent scientific needs, community requests, and bug reports. The position is funded by a Knut and Alice Wallenberg Foundation research project grant to Hiranya Peiris, Jens Jasche, Ariel Goobar, Jesper Sollerman, and Matthew Hayes.

The successful candidate will be part of the Oskar Klein Centre for Cosmoparticle Physics ( in Stockholm, a rich scientific environment that comprises more than a hundred researchers working in both theory and experiment in the fields of astronomy, astrophysics, and particle physics at both Stockholm University and the Royal Institute for Technology. The OKC hosts a vibrant research program on dark matter, dark energy, transient and multimessenger astrophysics, galaxy evolution, structure formation, and related particle physics questions.
