11+ SPARQL Jobs in Delhi, NCR and Gurgaon | SPARQL Job openings in Delhi, NCR and Gurgaon

AuxoAI is seeking a Senior Applied Scientist to design and deploy structured knowledge systems that enable reliable, schema-grounded AI and agent reasoning.

This role sits at the intersection of large language models, knowledge graphs, semantic architectures, and hybrid retrieval systems. The ideal candidate will build systems that transform unstructured data into structured knowledge representations, enforce semantic constraints, and enable hybrid symbolic–neural reasoning in production environments.

You will play a key role in designing scalable semantic infrastructures that support advanced AI use cases such as GraphRAG pipelines, structured extraction, and agent reasoning workflows.

You will work on problems where existing architectures may not be sufficient and will experiment with new approaches that combine machine learning, knowledge graphs, semantic constraints, and classical AI techniques to build reliable, production-grade systems.

Location - Mumbai/Bangalore/Hyderabad/Gurgaon (Hybrid - 3 Days a week in Office)

Responsibilities:

• Design schema-guided information extraction systems using zero-shot and few-shot structured prompting, constrained decoding approaches such as JSON schema enforcement or grammar-based decoding, and function-calling or tool-driven extraction techniques.
• Develop recursive or multi-stage extraction pipelines capable of handling nested entities, hierarchical structures, and cross-document relationships.
• Build ontology-driven systems using frameworks such as LinkML, OWL, SHACL, or similar schema modeling tools, and implement knowledge representations using RDF triples or labeled property graphs.
• Design and optimize entity resolution algorithms using techniques such as blocking strategies, embedding similarity, and rule-based matching.
• Develop ontology alignment techniques and graph embedding models such as Node2Vec or TransE-style approaches where appropriate.
• Design hybrid retrieval architectures combining dense vector retrieval, sparse retrieval techniques, and graph traversal algorithms such as BFS, DFS, path ranking, and neighborhood expansion.
• Build validation systems that enforce schema conformance, detect semantic inconsistencies, and reduce hallucinated or invalid structured outputs.
• Integrate structured knowledge systems into GraphRAG pipelines, agent planning frameworks, and tool-selection workflows.
• Deliver production-grade semantic systems with clear targets for latency, scalability, reliability, and data integrity.

Requirements

• 5+ years of experience building production AI or machine learning systems.
• Strong experience designing and implementing knowledge graphs or ontology-driven architectures.
• Hands-on experience implementing structured extraction techniques, including grammar-constrained decoding, JSON schema enforcement, or AST-style parsing approaches.
• Experience building entity resolution systems beyond simple embedding similarity methods.
• Experience working with graph query languages such as SPARQL or Cypher and optimizing graph query performance.
• Familiarity with RDF, OWL, or property graph data models and semantic data architectures.
• Strong Python engineering skills, with emphasis on data validation, schema integrity, and system reliability.
• Experience designing hybrid symbolic and neural AI systems.

Nice to Have:

• Experience implementing graph algorithms such as PageRank, community detection, or shortest-path algorithms for reasoning chains.
• Experience building graph-enhanced retrieval systems such as GraphRAG.
• Experience designing compositional semantic extraction pipelines.
• Experience implementing reasoning engines or rule-based inference systems.
• Experience benchmarking and evaluating structural extraction accuracy and consistency.

• Recruitment & Staffing: Attracting, interviewing, and hiring candidates for open positions.
• Employee Relations: Addressing employee concerns, managing workplace, and fostering a positive work environment.
• Performance Management: Implementing appraisal systems, setting performance standards, and providing feedback.
• Training & Development: Organizing training sessions, enhancing employee skills, and supporting career growth.
• Compliance & Policy Management: Ensuring adherence to labor laws and company policies, updating HR policies as needed.
• Payroll & Benefits Management: Overseeing payroll, administering benefits, and handling compensation matters.

Responsibilities:

• Engage directly with key clients through proactive communication, including outbound calls, virtual meetings, and in-person visits.
• Manage the complete sales cycle from lead generation to deal closure, ensuring a seamless end-to-end experience for the client.
• Understand client business needs, challenges, and objectives to offer tailored solutions that align with company services.
• Build and nurture strong, long-term relationships with key accounts to ensure high customer satisfaction and retention.
• Strategically follow up on leads and business inquiries, providing relevant information via email, calls, or meetings.
• Develop and maintain a comprehensive database of current and potential clients, tracking engagement and sales activity.
• Create and implement customized sales strategies, including cold outreach, networking, and lead qualification, to drive business growth.
• Proactively identify and pursue new business opportunities to consistently achieve and exceed revenue targets.
• Present and clearly explain services to prospective clients, showcasing value propositions and ROI.
• Conduct market research to identify emerging trends, competitor activity, and potential areas for business development.
• Meet and exceed monthly and quarterly sales targets by effectively managing a pipeline of key accounts.

Desired Candidate Profile:

• Experience: 1 to 4 years in key account management or B2B sales, with demonstrated success in end-to-end sales cycles.
• Strong communication, negotiation, and presentation skills.
• Ability to manage multiple client relationships and prioritize tasks effectively.
