Re: [isabelle] opening for a research engineer (post-doc) at MSR-INRIA Centre



As a follow-up to this announcement, we have now secured funding for a 24-month period for this post-doctoral position. The other information given in the original posting is still accurate. Apologies for resending.

> TLA+ is a language for specifying and reasoning about systems, including concurrent and distributed systems.  It is based on first-order logic, set theory, and temporal logic. TLA+ and its tools have been used in industry for over a decade.  More recently, we have extended TLA+ by a language for writing structured formal proofs and have developed TLAPS, a proof checker that contains an interpreter for the proof language and integrates different back-end provers. TLAPS is integrated into the TLA+ Toolbox, an IDE for TLA+ (http://research.microsoft.com/en-us/um/people/lamport/tla/tla.html).

It also supports the propositional fragment of temporal logic. This fragment is enough for proving safety properties (invariants and step simulation). We are currently refactoring the code base and preparing support for full temporal logic of TLA+, which will allow us to prove liveness and refinement properties.

> The research engineer (post-doctoral) position is funded by the PIA ADN4SE project (http://www.systematic-paris-region.org/en/projets/adn4se) that develops a real-time operating system and development tools for embedded systems based on PharOS. The system aims at providing certifiable correctness and performance guarantees, and fundamental properties of the operating system, such as determinacy, are formally verified using the TLA+ notation and tools.

> Your work will make a key contribution to this verification effort. In particular, you will work with members of the TLA+ project at the Microsoft Research - INRIA Joint Centre, including Damien Doligez, Leslie Lamport, and Stephan Merz on extending the TLA+ Proof System and its libraries. You will also work with the project partners of ADN4SE, and in particular members of CEA List, on modeling the protocols subject to verification and on carrying out the proofs. Your contributions will be conceptual, by identifying theories and patterns that underly the verification of the operating system, and practical, by implementing formal libraries and software in order to carry out the verification task.

Our tools are mainly implemented in OCaml. Some basic familiarity with concepts of real-time systems is a plus. Experience with temporal and modal logics, with interactive theorem provers or with Eclipse could be valuable.

However, the main focus is on practical applications and on the implementation of components of our tool chain that are missing or need improvement.
