Job Description

Hiring Manager: Mukesh Vijayvargia
Recruiter: Srimayee Banerjee
Engineer III, Software Development (Gen AI Engineer):
The GenAI Engineer will be responsible for designing, developing, and deploying AI-driven systems focused on document parsing, context understanding, and knowledge graph construction. The role combines expertise in generative AI models, large language model (LLM) frameworks, and graph-based data representation. The engineer will build scalable document understanding pipelines, extract relationships from unstructured data, and construct knowledge graphs (using technologies such as Neo4j) to enable intelligent information retrieval and reasoning across enterprise datasets.
Your responsibilities will include:

• Design and develop AI pipelines for document parsing, information extraction, and text understanding using LLMs and NLP techniques.
• Develop and refine algorithms for knowledge graph construction, entity linking, and relationship extraction from text corpora.
• Implement GenAI systems for summarization, semantic search, and contextual reasoning using retrieval-augmented generation (RAG).
• Work with vector databases, embedding generation, and model fine-tuning for domain-specific applications.
• Build and maintain scalable APIs and backend services to integrate GenAI capabilities with enterprise applications.
• Design and optimize Neo4j-based knowledge graphs to represent and query structured relationships from unstructured data.
• Collaborate with data scientists, AI/ML engineers, and software teams (frontend/backend) to integrate GenAI features into production.
• Evaluate and apply frameworks such as LangChain, LlamaIndex, Hugging Face, and OpenAI APIs for document intelligence workflows.
• Develop algorithms for semantic search, reasoning, and document-to-graph alignment using graph embeddings and transformer architectures.
• Ensure data quality, governance, and compliance with enterprise security and information management standards.
• Document research findings, maintain technical design specifications, and support continuous model improvement.

Required Qualification:

• Bachelor's or Master's degree in Computer Science, Artificial Intelligence, Data Science, or related field.
• 7-10 years of experience in AI, NLP, or Machine Learning with hands-on GenAI or document understanding experience.
• Strong proficiency in Python and familiarity with AI frameworks (PyTorch, TensorFlow).
• Experience with LLM-based document processing, prompt engineering, fine-tuning, and RAG pipelines.
• Hands-on experience with graph databases such as Neo4j and query languages like Cypher.
• Strong understanding of NLP, entity recognition, text classification, and relationship extraction.
• Experience with LangChain, LlamaIndex, Hugging Face Transformers, and OpenAI APIs.
• Knowledge of embeddings, vector stores, and semantic search algorithms.
• Familiarity with cloud platforms (AWS, Azure, GCP) for training and deploying AI models.
• Strong software engineering skills - version control, modular design, testing, and documentation.
• Excellent problem-solving abilities and cross-team collaboration skills.
• Exposure to regulatory and quality systems in medical device software development (e.g., ISO 13485, IEC 62304).

Preferred Qualification:

• Experience with ontology design or knowledge representation learning.
• Exposure to enterprise search systems such as ElasticSearch, FAISS, Pinecone.
• Understanding of multimodal AI (text, image, audio).
• Experience with MLOps techniques for deployment and monitoring.
• Background in biomedical or healthcare text analytics is a plus.

The anticipated compensation listed above and the value of core and optional employee benefits offered by Boston Scientific (BSC) - see --will vary based on actual location of the position and other pertinent factors considered in determining actual compensation for the role. Compensation will be commensurate with demonstrable level of experience and training, pertinent education including licensure and certifications, among other relevant business or organizational needs. At BSC, it is not typical for an individual to be hired near the bottom or top of the anticipated salary range listed above.
Compensation for hourly, non-sales roles may also include variable compensation from time to time (e.g., any overtime and shift differential) and annual bonus target (subject to plan eligibility and other requirements).
Compensation for salaried, non-sales roles may also include variable compensation, i.e., annual bonus target and long-term incentives (subject to plan eligibility and other requirements).
Compensation for sales roles is governed by Sales Incentive Compensation Plan (which includes certain annual non-discretionary incentives based on predetermined objectives).
Our organization is across Canada and has commercial representation in 140 countries.
This job involves regular collaboration with colleagues, clients, and stakeholders across Canada, the U.S., and/or internationally, making proficiency in English essential for effective communication and alignment. English is necessary for engaging with a range of documentation and maintaining effective communication if interacting with external clients or vendors.
As detailed in the job description, this job involves communicating, both verbally and in writing, with other Boston Scientific teams located across Canada, the United States and/or with our international clients and partners. International customers and partners represent an important part of our activities. Based on an evaluation, we have determined that the duties of Engineer III, Software Development (Gen AI Engineer) position require knowledge of English in addition to French (oral and written). We also determined that the English language skills already required of other employees do not permit the performance of English language skills tasks related to Engineer III, Software Development (Gen AI Engineer) position.
However, in Quebec, Boston Scientific limits as much as possible the number of positions for which it requires the knowledge of another language than French. Boston Scientific solely requires proficiency in English where it is necessary for the performance of an employee's duties.
