We are seeking a highly talented and motivated Senior R Developer (Senior Research Software Engineer for R) (f/m/d) to help us develop our R-based toolchain for cutting-edge software within an interdisciplinary environment as part of the core development team of the cross-industry, open-source project “Open Systems Pharmacology” Suite (OSP Suite with PK-Sim®, MoBi®, and R Packages,

About Us

esqLABS is an innovative, internationally acting  Contract Research Organization, and a global leader in the development and application of the open source OSP Suite ( We are a research-focused provider of specialized computational analyses in the life sciences industry (conducting “dynamic systems” modeling and simulation (M&S) and specialized software development). We collaborate with global corporations in the pharma and chemical industry as well as start-ups in the life-science technology sector and academic and non-profit research institutions. We define new standards in pharmacometrics and systems pharmacology, and toxicology. Our platforms help scientists understand mechanisms of disease and toxicity to optimize individualized treatment of patients and protect the health of the animal and human life.

Having started as key expert users of the OSP Suite, esqLABS expanded its activities and is now an active member of the OSP software developer team. In close collaboration with industry and academia, we are committed to software development to fulfill our own and our client’s needs and the needs of the open-source community.

As such, esqLABS has attracted international players as sponsors for the OSP Software development. In addition, funding through national and EU-wide research grants allows us to continue developing our core technologies.

The dynamic team behind esqLABS unites people with different backgrounds, spanning disciplines like pharmaceutical sciences, physics, bioinformatics, mathematics, data science, and software engineering.

  • Solutions for data visualization (ggplot, etc.) and reporting (RMarkdown/Quarto)
  • Improving user experience by implementing new features
  • Database integrations (e.g. mySQL)
  • Shiny applications
  • Compilation of training material
    In this role, you can help redefine the standards for analysis workflows used for M&S and data analysis in the Life Sciences.
    Our aim, with your contribution, is to make this software the market leader and a go-to tool for the industry.
