Context And Mission
The Wave Phenomena Group (WPG) of the Department of Computer Applications for Science and Engineering (CASE) leads the core design and implementation of an advanced agentic Artificial Intelligence (AI), as part of a 3-year European project. The core programming effort aims at making learning machines, interfaced with a natural language dialog system and augmented by a knowledge base, capable of reliable reasoning and action planning, leading to the automatic execution of fast simulations in the natural hazards area. This earth science application belongs to the general area of software engineering applied to Machine Learning (ML), asynchronous workflow orchestration, and agentic AI. To advance that initiative we seek several AI Software Engineers and specialists from Junior to Senior, who will team up in the development of algorithms and workflows.
As an on-premise, full-time AI software specialist, you will integrate a tight-knit team of 8 people on-site, plus other ML/AI specialists and geoscientists located at European partnering organizations. Together you will tackle the design and fine-tuning of a robust and trustworthy LLM-RAG system, probabilistic and symbolic reasoning, workflow orchestration, and scalable AI infrastructure.
Key Duties
* Develop modular components for the AI agent's functional modules:
◦ HMI (LLM-RAG chatbot),
◦ RAP (Reasoning & planning),
◦ BELIEF (Serialize and update a probabilistic knowledge model of the agent’s environment and track state transitions, uncertainty propagation),
◦ PERCEPTION (Automatic acquisition of data via a remote subscribed service),
◦ ACTUATION (abstraction layer to execute simulations, via Digital Twins, Digital Twins’ surrogates or other downstream tools, in response to RAP directives and resource-aware invocation logic),
◦ LEARNING (Continuously update the AI agent’s strategy, embedding space, and planning heuristics based on feedback from executed plans).
* Implement multi-tenancy, low-latency, asynchronous execution workflows.
* Contribute to execution graph translation and tool invocation logic.
* Containerize code modules and packages to be integrated / deployed in larger workflows.
* Maintain code quality, tests, and documentation, without incurring technical debt.
* Formulate and evaluate new ideas in a rigorous way.
* Collaborate with scientists and engineers, on a weekly basis, across partner institutions.
