Postdoc in Semantics Engineering
The Department of Software and Computer Technology of TU Delft has a postdoc position in Semantics Engineering in the NWO VICI project of Eelco Visser:
The objective of the project is to unify work on semantics engineering and mechanized meta-theory with work on language engineering and language workbenches in order to support language designers in the creation of sound language designs. The Language Designer's Workbench will provide declarative meta-languages to enable language designers to build high quality compilers and IDEs, while also verifying consistency properties of their language definitions. We will build on our previous work on the Spoofax Language Workbench and integrate work on compiler certification from the semantics engineering community.
The grant provides funding for five researchers at PhD and postdoc level. The focus of this position is on semantics engineering of programming languages. But candidates interested in all aspects of the project are invited to apply.

Software Language Design and Engineering
This position is part of the NWO VICI project The Language Designer's Workbench and will be performed within the Software Engineering Research Group under supervision of Dr. Eelco Visser. The mission of our Software Language Design and Engineering team is to enable software engineers to effectively design, implement, and apply domain-specific languages with research in three tracks:
Language engineering: investigate the automatic derivation of efficient, scalable, incremental compilers and usable IDEs from high-level, declarative language definitions
Semantics engineering: investigate the automatic verification of the consistency of language definitions in order to check properties such as type soundness and semantics preservation
Language design: investigate the systematic design of domain-specific software languages with an optimal tradeoff between expressivity, completeness, portability, coverage, and maintainability.
The Language Designer's Workbench
Domain-specific software languages (DSLs) reduce the gap between requirements and implementation through linguistic abstraction by providing notation, analysis, verification, and optimization that are specialized to an application domain. Language workbenches assist language designers with the implementation of languages. However, DSL implementations rarely formally guarantee semantic correctness properties such as type soundness and semantics preservation of transformations, since current language workbenches provide no support for such verification, which leads to intricate errors in language designs that are discovered late.
In the Language Designer's Workbench project, we will work towards new methods and techniques for automating the verification of language definitions. The key innovations are: (1) High-level formalisms for the declarative specification of software languages; (2) Efficient and scalable language parametric algorithms for name resolution, type checking, and program execution; (3) Language parametric test generators that attempt to generate counter examples to the correctness of language definitions; (4) Language parametric proof engineering techniques to support automated verification of language definitions.
The techniques will be integrated in the Spoofax Language Workbench and should enable DSL designers to detect semantic errors at low cost in the early stages of the design process. We will evaluate the techniques by verifying and testing a representative set of language definitions.
The funding of 1.5M Euro from NWO for this project enables us to significantly expand the SLDE team to pursue this research agenda.
The postdoc will join a world-leading team in software language engineering to contribute to the objectives of the project. The focus of this particular position is on semantics engineering of programming languages. But candidates interested in all aspects of the project are invited to apply.
An enthusiastic postdoc with a PhD degree in Computer Science. The candidate should have a strong background in programming languages research and a demonstrable interest in one or more of the following topics: type systems, type inference algorithms, program analysis, program transformation, compiler construction, theorem proving and proof assistants, verification of language definitions or compilers, mechanized meta-theory.
We are looking for a researcher with an independent mind who is willing to collaborate in our team. It is understood that he or she works on the topics listed above, and contributes to the objectives of the project. Further we ask for good communicative and collaborative skills. The working language of the group is English. Starting date: October 1st, 2013, or as soon as possible thereafter.
A postdoc position initially for one year, with possible extension to three years (38 hrs/week) in a stimulating scientific environment. Gross salary starting at EUR 3037 per month (depending on experience) with Holiday allowance (8%) and end-of-year bonus (8.3%). In addition, TU Delft offers an attractive benefits package, including a flexible work week, free high-speed Internet access from home (with a contract of two years or longer), and the option of assembling a customised compensation and benefits package (the 'IKA'). Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities.
