Le CEA est un acteur majeur de la recherche, au service des citoyens, de l'économie et de l'Etat.
Il apporte des solutions concrètes à leurs besoins dans quatre domaines principaux : transition énergétique, transition numérique, technologies pour la médecine du futur, défense et sécurité sur un socle de recherche fondamentale. Le CEA s'engage depuis plus de 75 ans au service de la souveraineté scientifique, technologique et industrielle de la France et de l'Europe pour un présent et un avenir mieux maîtrisés et plus sûrs.
Implanté au cœur des territoires équipés de très grandes infrastructures de recherche, le CEA dispose d'un large éventail de partenaires académiques et industriels en France, en Europe et à l'international.
Les 20 000 collaboratrices et collaborateurs du CEA partagent trois valeurs fondamentales :
• La conscience des responsabilités
• La coopération
• La curiosité

CEA's technology research division (DRT) has a portfolio of technologies in the fields of information and communication, energy and health. As an interface between research and industry, our mission is to develop and transfer technologies, from theoretical proof of concept to industrial demonstrators, effectively bridging the gap between research and industry.
CEA List, a research institute specialized in intelligent digital systems, is located in the heart of the Paris-Saclay science and technology cluster.
Within the CEA List, the Electronics Design Automation and Architectures Laboratory (LECA) has the mission to design innovative and flexible system-on-chip architectures that meet the challenges of performance, cost, energy consumption, safety and security, targeting critical embedded systems and HW accelerators for embedded AI. To reduce the development time and improve the quality of these architectures, the team of experts develop innovative design tools and methods.

We are looking for a co-design engineer for future computing architectures with optical component. This position, in a fixed-term contract, is based at the Nano-Innov site of Paris-Saclay, Essonne (91).
As part of a multidisciplinary team specializing in hardware IP design and EDA tools, you will develop innovative methodologies and tools for HW/SW co-design of electronic architectures, focusing on high-performance computing (HPC) and AI systems.
You will leverage VPSim (virtual prototyping) and A-DECA (architecture exploration)—tools that enable HW modeling, binary SW execution, functional validation, and performance analysis in a fully virtualized environment. These tools integrate QEMU-based emulation, external models, and a Python API for performance data extraction during application execution. A-DECA further supports efficient design space exploration via optimization strategies.
This role is part of EU-funded research projects on next-gen HPC networks and open-source EDA tools, with a focus on optical/photonic interconnects to address latency, bandwidth, and scalability challenges in large-scale computing.
In the course of your mission, you will be required to :
- Understand the technical specifications of the computing system integrating an optical link and develop appropriate model in VPSim plateform
- Develop a high-level virtual prototype based on CEA VPSIM simulation tool to provide first estimations of KPIs and to allow system-of-chiplets architecture exploration;
- Determine best architectural parameters in terms of power, performance, area as well as sustainability using A-DECA tool;
- Collaborate/communicate with other research partners involved to expand CEA VPSIM tool to model optical-switch based architectures;
- Ability to assess, prepare, and contribute software components to open-source ecosystems
- Participate in the scientific dissemination of the team's research results (contributions to publications in national and international conferences), design of videos, demonstrations and tutorials as well as in the valorization of our innovations.

- Knowledge of digital electronic architecture (processors, Caches, NoC, ...) ;
-High level programming language: C++/Java/Scala ...
- Scripting languages : Bash/Python ...
- Development tools : IDE, make/cmake, svn/git, continuous integration, docker ...
- Git environement
Desired experience and/or skills:
- Experience in simulation/emulation, especially with QEMU
- Knowledge in Linux kernel development;
- Experience in other scripting languages (bash, tcl) would be a plus.
- Knowledge in the field of operational research and/or machine learning algorithms would be a plus.
In accordance with the commitments made by the CEA to promote the integration of disabled people, this job is open to all. The CEA proposes arrangements and/or organizational possibilities for the inclusion of disabled workers.

The CEA is the French Alternative Energies and Atomic Energy Commission ("Commissariat à l'énergie atomique et aux énergies alternatives"). It is a public body established in October 1945 by General de Gaulle. A leader in research, development and innovation, the CEA mission statement has two main objectives: To become the leading technological research organization in Europe and to ensure that the nuclear deterrent remains effective in the future.
The CEA is active in four main areas: low-carbon energies, defense and security, information technologies and health technologies. In each of these fields, the CEA maintains a cross-disciplinary culture of engineers and researchers, building on the synergies between fundamental and technological research.
The civilian programs of the CEA received 49% of their funding from the French government, and 30% from external sources (partner companies and the European Union).
The CEA had a budget of 4,3 billion euros.
The CEA is based in ten research centers in France, each specializing in specific fields. The laboratories are located in the Paris region, the Rhône-Alpes, the Rhône valley, the Provence-Alpes-Côte d'Azur region, Aquitaine, Central France and Burgundy. The CEA benefits from the strong regional identities of these laboratories and the partnerships forged with other research centers, local authorities and universities.
