DESY, with more than 2900 employees at its two locations in Hamburg and Zeuthen, is one of the world's leading research centres. Its research focuses on decoding the structure and function of matter, from the smallest particles of the universe to the building blocks of life. In this way, DESY contributes to solving the major questions and urgent challenges facing science, society and industry. With its ultramodern research infrastructure, its interdisciplinary research platforms and its international networks, DESY offers a highly attractive working environment in the fields of science, technology and administration as well as for the education of highly qualified young scientists.

The PUNCH4NFDI consortium aims at a sustainable utilisation of research data and the establishment of FAIR and open science for particle physics, astroparticle physics, astronomy, and hadron & nuclear physics. The consortium is part of the German national research data infrastructure (Nationale Forschungs­daten­infrastruktur, NFDI) and supported by around 35 institutions – university institutes, Max Planck institutes, Helmholtz centres, as well as Leibniz institutes.

As software developer, you will work for PUNCH4NFDI to set up and extend distributed data management frameworks for different scientific communities, including the Cherenkov Telescope Array Observatory (CTAO), the International Lattice Data Grid (ILDG), the German Long Wavelength consortium (GLOW), or high energy physics experiments at DESY.

About your role:

• Develop and extend services for the Authentication and Authorization Infrastructure (AAI) of federated data management systems with hierarchical access control

• Develop and improve catalogue services that manage metadata for large scientific data sets in distributed storage

• Integration, test, and deployment of AAI and (meta-)data services

• Help to write documentation and to train project partners

About you:

• University degree in computer science, physics, mathematics, engineering or related subject, or comparable qualification

• Strong programming experience in Java and JavaScript, including the design and implementation of web services and applications with REST API

• Sound knowledge of token-based authentication and authorization (e.g., OAuth2, OpenID Connect), and familiarity with federated identity protocols (e.g., SAML 2.0), as well as with identity and access management solutions (e.g., Keycloak)

• Good knowledge of Linux, of modern DevOps practices (e.g., version control with Git, build automation, CI/CD with GitLab), and of containerization with Docker

• Familiarity with relational or NoSQL databases (e.g., PostgreSQL, MongoDB) and with metadata modelling

• Familiarity with the FAIR principles of scientific data management is advantageous

• Familiarity with Kubernetes and Helm is desirable

• Knowledge of configuration management tools (e.g., Terraform, Ansible), and of monitoring and logging tools (e.g., Prometheus, Grafana) is preferable

• Experience with Python or Go for scripting and service development is advantageous

• Very good command of written and spoken English
