The Senior Semantic Web Engineer will develop semantic web applications, manage knowledge graph solutions, lead projects, and collaborate closely with interdisciplinary teams.
We are seeking a skilled and motivated Senior Semantic Web Engineer to join our team. In this role, you will work on advanced knowledge graph technologies, combining expertise in semantic web engineering, data modeling, and cloud-based solutions. You will collaborate closely with a team of scientists, developers, and architects to design and implement scalable semantic web applications that support healthcare data intelligence. This is an excellent opportunity for someone with strong engineering skills and a passion for applying semantic technologies to real-world challenges in a dynamic and fast-growing environment.
WHAT YOU'LL DO:
- Serve as a subject matter expert in semantic web development on our graph data team, contributing to initiatives that integrate AI, LLMs, and advanced graph technologies.
- Collaborate with the Staff Semantic Engineer and other senior engineers to standardize tooling, design patterns, and modeling approaches.
- Help define the technical direction for core semantic capabilities, ensuring scalable and robust solutions.
- Independently research, evaluate, and propose innovative solutions to complex and ambiguous technical challenges.
- Build and manage scalable knowledge graph solutions, including data ingestion, linking, and querying mechanisms.
- Write, test, and document clean, maintainable code, and apply automation to testing, integration, and deployment processes.
- Partner with product owners to refine features into actionable user stories that deliver business value.
- Evaluate and recommend external taxonomies and ontologies; author new ones as needed to support our domain.
- Recommend and implement semantic web tools, platforms, and technologies.
- Support ontology governance processes and enterprise graph management tools.
- Collaborate with stakeholders, including data scientists, engineers, and developers, to understand requirements and build effective semantic solutions.
- Provide technical mentorship to junior team members on semantic web principles and implementation patterns.
WHAT YOU'LL NEED:
- Bachelor’s or Master’s degree in Computer Science, Information Technology, or a related STEM field
- 5+ years of hands-on experience in semantic web or knowledge graph engineering, including leading complex projects.
- Proven experience with graph databases or triple stores such as Amazon Neptune, Neo4j, Virtuoso, or GraphDB. (Amazon Neptune preferred)
- Strong proficiency in Python; familiarity with other languages (e.g., Java, C#, JavaScript, Clojure) is a plus.
- Practical experience with RDF, OWL, SPARQL, and ideally SHACL.
- Experience with relational databases (SQL) and graph databases (SPARQL).
- Hands-on experience with ontology/graph tools such as Protégé, TopBraid, or Metaphactory. (Metaphactory preferred)
- Solid understanding of data modeling, ETL processes, and data governance.
- Experience with cloud platforms (AWS preferred) and their data services.
- Understanding of AI/ML concepts and how semantic data can enhance AI applications.
- Familiarity with CI/CD, agile practices, and infrastructure tools like Git, Jenkins, Azure DevOps, and Terraform.
- Strong communication and problem-solving skills, with the ability to explain complex technical concepts to non-technical stakeholders.
- Bonus: Understanding of healthcare ontologies and standards like SNOMED-CT, LOINC, RxNorm, and ICD-10.
