Position Description ==================== The Coordination and Component Based Software group in SEN3 at CWI has two open positions for: (1) a postdoc for a period of four years, and (2) a PhD student (OIO) for four years. Both positions are within the project number 600.065.120.03N02 Compositional Construction of Component Connectors (C-Quattro), recently funded by the NWO (the Dutch government's funding agency for academic scientific research), with F. Arbab (CWI) and J. Rutten (CWI and VUA) as Principal Investigators. The project C-Quattro is in fact a collaboration of SEN3 at CWI with the Section Theoretical Computer Science at the Free University of Amsterdam (VUA). The postdoc will be employed by CWI; the PhD student will be employed by the VUA but will spend part of his or her time at CWI. The main goal of the C-Quattro project is to develop an operational semantics based on a calculus of component connectors, as the foundation for further development of practical tools and programming environments for the actual deployment of Reo. Reo is a recently introduced channel-based coordination model wherein complex coordinators, called connectors, are compositionally built out of simpler ones. Reo is intended as a ``glue language'' for construction of connectors that orchestrate component instances in a component-based system. The emphasis in Reo is on connectors and their composition only, not on the components that are being connected. The activities under C-Quattro involve both system oriented and theoretical work. On the systems side, we develop tools supporting visual connector programming, as well as the automation of equivalence proofs, e.g., for optimization. On the theoretical side, the semantic modeling is based on the coalgebraic methodology, and coinduction, with its potential for automation, will be the main reasoning principle. The candidate for the postdoc position is expected to have a strong background in Software Engineering, maturity in formal methods and their practical applications, familiarity with component-based software, concurrency, and coordination. Teamwork and leadership, as well as the ability to work effectively with academic colleagues and PhD students, are all important qualifications for this position. The candidate for the PhD position should have a master degree in computer science or mathematics, with a clear interest in questions from theoretical computer science. Ideally, the candidate has a background both in mathematical disciplines such as algebra, analysis and discrete mathematics, and in such elements of theoretical computer science as automata theory and semantics. The Theme SEN3 (http://www.cwi.nl/sen3) at CWI is a dynamic group of internationally recognized researchers who work on Coordination Models and Languages and Component-Based Software Composition. The activity in SEN3 is a productive, healthy mix of theoretical, foundational, and experimental work in Computer Science, ranging in a spectrum covering mathematical foundations of models of computation, formal methods and semantics, implementation of advanced research software systems, as well as their real-life applications. General information =================== CWI is an internationally renowned research institute in mathematics and computer science, located in Amsterdam, The Netherlands. The focus is on fundamental research problems, derived from societal needs. Research is carried out in 15 research themes. More information about these themes can be found on the website www.cwi.nl where you can also take a look at our Annual Report. A substantial part of this research is carried out in the framework of national or international programs. CWI maintains excellent relations with industry and the academic world, at home as well as abroad. After their research careers at CWI, an increasing number of young staff members find employment in these sectors, for example in spin-off companies that are based on research results from CWI. Of course, library and computing facilities are first-rate. CWI's non-scientific services to its personnel include career planning, training & courses, assistance in finding housing, and tailor-made solutions to problems that may occasionally arise. Terms of employment =================== The salary is in accordance with the "CAO-onderzoekinstellingen" and is commensurate with experience. For instance, the postdoc base salary for a fresh PhD with no additional experience in scale 10 is around 2800 Euros/month, and for an experienced PhD in scale 12 it is around 4500 Euros/month. The current starting salary for a first year PhD student is around 1500 Euros/month with an incremental raise for each subsequent year. (Note: a considerable increase in the salaries of all PhD students is currently under negotiation). Besides the salary, CWI offers very attractive and flexible terms of employment, like a collective health insurance, pension-fund, etc. Application =========== For more information on these vacancies you can contact either of the PIs: F.
