Job Description & How to Apply Below
Lead the architecture and engineering of an AI-assisted decision-systems prototype. You will design the agentic workflow, evaluation framework and control boundaries that connect authoritative source material to controlled representations, a deterministic language, standard data, and downstream implementations.
What you do- Own the end-to-end technical architecture and engineering roadmap for the prototype.
- Design multi-agent workflows for extraction, decomposition, transformation, validation, comparison, and explanation of complex rule sets.
- Define where generative AI is appropriate and where deterministic code, schemas, constraints, and human approval are required.
- Engineer structured outputs, tool/API contracts, evaluation harnesses, golden datasets, error taxonomies, and regression tests.
- Work closely with the language/data architect so agent outputs conform to the DSL grammar, standard schema, and graph model.
- Create observable background across source evidence, agent transformations, human decisions, and generated artefacts.
- Provide technical leadership across AI, data, SAP, and assurance specialists.
- Deep experience designing and delivering GenAI/LLM systems beyond proof-of-concept prompting.
- Hands-on experience with agent orchestration, tool use, structured outputs, retrieval, and evaluation.
- Strong API/software-engineering skills, including automated testing.
- Experience designing AI quality measures, failure handling, human-in-the-loop controls, and auditability.
- Ability to lead architecture across AI, data models, line graphs, and enterprise systems.
- Knowledge representation, formal methods, or rules engines.
- Compiler/DSL awareness sufficient to collaborate on constrained generation.
- Knowledge graphs or graph databases such as Neo4j/RDF-based technology.
- Experience delivering AI in regulated, financial, government or other high-assurance environments.
