You will be the architect of the \"brain\" of our platform, solving the hardest problems in semantic search and graph-based reasoning at a scale few companies ever reach. This role offers a unique opportunity to define the data infrastructure strategy that powers our GenAI future. \nAbout the Team:\nYou are a retrieval-oriented engineer with deep expertise in high-dimensional data, relational structures, and large-scale knowledge representation. You thrive on the challenge of bridging the gap between raw data and semantic understanding, building the backbone for next-generation AI and discovery systems. You are passionate about data topology, latent space optimization, and the performance tuning of complex query engines. You constantly strive to reduce \"time-to-insight\" and maximize the precision of information retrieval at scale.\nThe pace of our growth is incredible-if you want to tackle the foundational challenges of RAG (Retrieval-Augmented Generation), knowledge graphs, and semantic search at a global scale, join us!\nKey Responsibilities:\nLead the design and development of hybrid retrieval architectures combining vector similarity search with structured graph traversals.\nArchitect scalable data pipelines for the ingestion, embedding, and indexing of massive, multi-modal datasets.\nInnovate and prototype advanced retrieval techniques, including multi-stage re-ranking, graph-tooling for LLMs, and dynamic metadata filtering.\nDesign and implement schemas for complex knowledge graphs, ensuring high-performance relationship mapping and ontological integrity.\nBuild automated data validation and drift detection systems to monitor the quality of embeddings and the health of the vector space.\nDrive technical implementation of \"Memory\" systems for AI agents, focusing on long-term persistence, observability, and sub-second latency.\nChampion data organization standards, ensuring that disparate data sources are unified into a coherent, searchable knowledge base.\nCollaborate with AI Research and Product teams to evaluate emerging database technologies (e.g., HNSW optimizations, GraphRAG) and integrate them into production.\nSkills and Attributes for Success:\n7+ years of experience in data engineering or backend systems with a focus on high-performance data retrieval and storage.\nExpert proficiency in Python, Java, or Go, with a strong grasp of distributed system design patterns.\nDeep understanding of Vector Databases, including indexing strategies (HNSW, IVFFlat, PQ) and distance metrics (Cosine, Euclidean, Dot Product). Experience with Pinecone, Milvus, Weaviate, or Qdrant.\nStrong background in Graph Databases (Neo4j, AWS Neptune, or ArangoDB) and query languages like Cypher or Gremlin.\nExperience with Data Modeling and organization, specifically in building semantic layers, ontologies, and taxonomies.\nHands-on experience with LLM orchestration frameworks (LangChain, LlamaIndex) and embedding models (OpenAI, HuggingFace, Cohere).\nProficiency in large-scale data processing using Spark, Flink, or Kafka for real-time indexing and ETL.\nUnderstanding of Information Retrieval (IR) fundamentals, including BM25, TF-IDF, and reciprocal rank fusion.\nExperience with cloud-native infrastructure (AWS/GCP/Azure) and container orchestration (Kubernetes).\nPreferred Education and Experience:\nBachelors/master's in computer science or a related field with 7-9 years of professional experience","description_format":"text","description_chars":3595,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Broadcasting","Streaming & OTT Platforms"],"lifecycle":[{"event":"open","at":"2026-09-05T16:39:36Z"}],"visa":[],"liveness":{"score":13,"band":"cold","label":"Long shot","p_open":1,"p_active":0.449,"p_room":0.28,"age_days":146,"expected_fill_days":44,"reasons":["conf:3","stale_co","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-25T05:49:26Z"},"pay":null,"html_url":"https://alion.io/job/jiostar-staff-software-development-engineer-data-engineer","json_url":"https://alion.io/job/jiostar-staff-software-development-engineer-data-engineer.json","meta":{"generated_at":"2026-10-26T01:03:56Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":1359,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-27T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":8901},"rest":"https://alion.io/mcp/rest/get_company?id=8901"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fjiostar-staff-software-development-engineer-data-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fjiostar-staff-software-development-engineer-data-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fjiostar-staff-software-development-engineer-data-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/jiostar-staff-software-development-engineer-data-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fjiostar-staff-software-development-engineer-data-engineer"}]}
