Senior AI Python Engineer
First seen by Alion on Sep 24, 2026.
Key Responsibilities :
- Design, build, and maintain agentic AI pipelines (using Google ADK or similar frameworks) to automate semantic mapping, dimension mining, and ontology-driven reasoning.
- Create and evolve enterprise ontologies in RDF/OWL, including upper ontologies and domain extensions aligned to CIM (where applicable), to enable reusable enterprise semantics.
- Engineer LLM-powered services for schema understanding, semantic alignment, ontology enrichment, and AI-assisted metadata generation, with a focus on accuracy, traceability, and scale.
- Implement SPARQL querying and reasoning layers over knowledge graphs to drive downstream transformations and ensure consistent interpretation of business concepts.
- Architect and deliver Python-based microservices and batch pipelines that integrate semantic reasoning with modern data-engineering workflows.
- Build and optimize dimension and fact generation pipelines on Microsoft Fabric (Lakehouse, Spark, SQL, orchestration) to produce business-ready star schemas from heterogeneous sources.
- Define and enforce engineering standards, design patterns, and reusable components for semantic and AI-driven data platforms (quality, observability, security, and performance).
- Partner with data architects, domain SMEs, and governance teams to validate semantic definitions, manage change, and ensure platform scalability and adoption.
- Conduct code reviews, mentor engineers, and influence technical decisions across the platform to raise engineering quality and delivery velocity.
Required Skills & Qualifications :
- 6+ years of professional software engineering experience, with strong proficiency in Python and GenAI.
- Hands-on experience building LLM-based systems using commercial or open-source models.
- Solid understanding of semantic technologies : RDF, OWL, ontologies, knowledge graphs, and SPARQL.
- Experience designing or working with agentic AI frameworks (e.g., Google ADK, LangChain agents, or similar).
- Strong background in data engineering concepts (ETL/ELT, star schemas, metadata-driven pipelines).
- Experience building and operating systems on cloud platforms, preferably Microsoft Azure / Microsoft Fabric.
- Strong problem-solving skills and ability to work in ambiguous, greenfield platform initiatives.
Preferred Skills :
- Experience with enterprise data models (e.g., CIM or canonical models).
- Familiarity with semantic alignment, ontology mapping, or data cataloguing tools.
- Exposure to MLOps / LLMOps, model evaluation, and AI observability.
- Knowledge of distributed systems, CI/CD pipelines, and containerisation.
- Experience building AI-assisted analytics or semantic layers for BI or NLQ use cases.
