“If you are passionate about leveraging machine learning and harnessing the capabilities of Large Language Models (LLMs) to create innovative solutions tailored for regulatory and compliance challenges within the legal landscape, then this is the right opportunity for you. Be a part of the team of research and machine learning scientists and get mentored by some of the best minds in AI.”
- Maithrreye, Machine Learning Scientist.
About the Role
This is a paid residency that will be undertaken over a twelve-month period with the potential to be hired by our client Ultimarii afterwards (note: at the discretion of the client). The resident will be reporting to an Amii Scientist and regularly consult with the Client team to share insights and engage in knowledge transfer activities. At the end of the engagement, it is expected that the work could be publishable to a respected conference or journal.
About our Client
Ultimarii is a leading technology company based in Calgary, Alberta, Canada, dedicated to accelerating major projects. At Ultimarii, we harness the power of artificial intelligence to create innovative products and services that meet the evolving needs of Project Owners and the consultants that support them. Ultimarii is committed to creating a diverse environment and is proud to be an equal opportunity employer.
About the Project
This project involves researching, evaluating, and benchmarking graph retrieval strategies to enhance our existing hybrid RAG pipeline with a GraphRAG layer. The resident will investigate methodologies for building and populating domain-specific knowledge graphs from unstructured regulatory and legal text - including entity and relation extraction - and design graph retrieval strategies. These graph-augmented approaches will be benchmarked against our baseline hybrid search pipeline using real-world queries and measurable evaluation metrics to improve context quality, enable multi-hop reasoning, and reduce retrieval noise across large document collections. Additionally, the project would see the chosen solution through the production implementation phase for further performance and retrieval quality optimization.
Required Skills / Expertise
Are you passionate about building great solutions? Do you want to drive a high impact early-stage business? You’ll be presented with opportunities to both personally and professionally develop as you build your career. We’re looking for a talented and enthusiastic individual with a solid background in machine learning, specifically in LLMs and applied NLP.
Key Responsibilities:
- Experiment and extend an existing hybrid RAG pipeline by integrating a graph knowledge layer to enable deeper, entity-aware generation
- Build and populate a domain-specific knowledge graph from unstructured text including entity extraction, relation extraction, and graph schema design
- Experiment with and evaluate graph retrieval strategies benchmarking graph-augmented approaches against the baseline pipeline using real queries and measurable metrics
- Build, train, and evaluate features for LLM applications working iteratively across design, experimentation, and deployment
- Collaborate with the project team and stakeholders to develop MVP and client-focused solutions, undertaking applied research to address limitations in existing models
- Participate in regular meetings with the client, preparing presentations and reports on findings and progress
Required Qualifications:
- Completion of a graduate level program or higher (M.Sc/Ph.D) in Computing Science, ML or Engineering
- Research or project experience in Natural Language Processing, Knowledge Graphs, and Large Language Models
- Previous experience with LLM use-cases and RAG architectures
- Proficient in Python and related ML frameworks, libraries and toolkits (e.g. Scikit-learn, PyTorch, Pandas, Jupyter, Transformers, HuggingFace Datasets, LangChain, LlamaIndex, Neo4j Python driver, NetworkX, PyTorch Geometric, spaCy)
- Experience with graph-based data structures, knowledge representation, or semantic web technologies (RDF, OWL, SPARQL is a bonus)
- Familiarity with entity extraction and relation extraction methods (e.g. spaCy, Rebel, GLiNER, LLM-based extraction) and graph database/ libraries (e.g. PyG, DGL, NetworkX, Neo4j)
- A positive attitude towards learning and understanding a new applied domain
- Must be legally eligible to work in Canada
Preferred Qualifications:
- Previous experience applying machine learning in NLP, LLMs, and Generative AI projects including prompt engineering, fine-tuning, or retrieval pipeline optimization
- Hands-on experience in AI/ML development projects
- Publication record in peer-reviewed academic conferences or relevant journals in machine learning
Non-Technical Requirements:
- Desire to take ownership of a problem and demonstrated leadership skills
- Interdisciplinary team player enthusiastic about working together to achieve excellence
- Capable of critical and independent thought
- Able to communicate technical concepts clearly and advise on the application of machine intelligence
- Intellectual curiosity and the desire to learn new things, techniques, and technologies
- Industry experience in energy, project engineering, environmental or legal studies will be considered an asset.
Why You Should Apply
Besides gaining industry experience, additional perks include:
- Work under the mentorship of an Amii Scientist for the duration of the project
- Participate in professional development activities
- Gain access to the Amii community and events
- Build your professional network
- The opportunity for an ongoing machine learning role at the client’s organization at the end of the term (at the client’s discretion)
