Job description

Does working for 150+ million children of Bharat excite you?

Then this opportunity is for you!

About us:

ConveGenius is an impact-first organisation, building platforms and systems for public education and skilling at population scale. We work closely with governments, ecosystem partners, social enterprises, philanthropies and individual & institutional investors, with a goal to deliver the highest return on investment across offerings that improve learning, teaching, and governance.

Unlike traditional ed-tech companies that deliver content, we build infrastructure platforms that integrate deeply into public delivery systems, while enabling our partners to scale their missions with measurable results. Today, we operate across 22+ Indian states, trusted by governments and institutional investors alike, for aligning policy priorities with last mile impact. What started with belief and hope 13 years ago is now backed by evidence.

Our offerings include

• SwiftChat (the platform on which we build with ecosystem partners)
• SwiftPAL - validated by a two-year RCT led by Nobel laureate Prof. Michael Kremer (Development Innovation Lab, University of Chicago), whose team found students gained "almost an additional 2 years of extra learning" in just 17 months
• Swiftee (the AI learning tutor built for Bharat).

Our team comprises of thinkers, builders, innovators, and doers who show up every day with a strong action bias to build for Bharat.

• Design and maintain domain ontologies covering educational content, skills taxonomies, learner models and curriculum structures.
• Define ontology standards, schema versioning and governance processes across the knowledge platform.
• Model entities, relationships and semantic hierarchies using RDF / OWL and property-graph representations.
• Build and maintain knowledge base construction and entity resolution pipelines from
• Support GraphRAG architectures by structuring ontologies for LLM retrieval pipelines and contextual AI responses.
• Define and enforce knowledge quality standards, including completeness checks, consistency validation and remediation workflows.
• Work with graph database teams on query patterns, index design and performance tuning of
• Design semantic search capabilities that combine graph-native and vector-based hybrid retrieval approaches.
• Collaborate with ML and product teams on graph-native features such as recommendations, adaptive learning paths and gap detection.
• Document ontology design decisions, mapping rules and controlled vocabularies for
• Evaluate and evolve semantic technology standards as platform and data complexity scales.

Qualifications:

• B.Tech / B.E. / M.Tech / MCA in Computer Science, Information Science or equivalent.
• 4+ years of experience in ontology engineering, knowledge representation or semantic data

Must-have skills:

• Ontology & Knowledge Modelling – Designing domain ontologies, taxonomies and semantic
• RDF / OWL / SPARQL – Semantic web standards for representing, reasoning over and querying knowledge.
• Property Graphs & Cypher – Graph-native modelling and querying with Neo4j, JanusGraph, Apache Jena or similar.
• Knowledge Graph Construction – Entity resolution and knowledge base pipelines from
• Ontology Governance – Schema versioning, quality standards, consistency validation and remediation.
• Semantic Technologies & Reasoning – Inference pipelines and graph-based data integration.
• GraphRAG & Semantic Search – Structuring ontologies for LLM retrieval and hybrid
• Problem Solving – Ability to model ambiguous domains into clean, scalable semantic structures.
