This is a deep backend role for an engineer who cares about data modeling, query performance, and correctness under scale - and who wants their work to sit on the critical path of every agent interaction across the Aivar platform.\nKey Responsibilities\nImplement the context graph data layer: schema, entity and relationship management, versioning, and time-aware (temporal) memory records.\nBuild streaming and batch ingestion pipelines that capture events from Convogent conversations, Velogent process runs, and customer systems of record - with idempotency, ordering, and replay support.\nDevelop entity resolution and deduplication: matching customers, accounts, and interactions across channels into a single coherent graph identity.\nImplement the hybrid retrieval service - graph traversal, vector k-NN, and metadata filtering - with caching, pagination, and strict latency budgets.\nBuild and maintain Aiva's public APIs and internal SDKs (REST/gRPC, and MCP-compatible tool surfaces) with robust authentication, rate limiting, and multi-tenant scoping.\nOwn performance engineering: query profiling, index design, load testing, and capacity/cost tuning across graph and vector stores.\nImplement data lifecycle mechanics: TTL and decay policies, archival, tenant-scoped deletion (right-to-be-forgotten), and audit logging in line with AI Gateway governance policies.\nWrite thorough tests, runbooks, and operational dashboards; participate in on-call for the platform.\nMust-Have Qualifications\n6+ years of backend engineering in Python, Go, or Java/Kotlin, building services in production at meaningful scale.\nHands-on production experience with at least one graph database (Neptune, Neo4j, ArangoDB) or a demonstrated ability to model highly connected data in relational/NoSQL stores.\nPractical experience with search/vector retrieval: OpenSearch/Elasticsearch, pgvector, or a dedicated vector database, including index tuning and relevance debugging.\nStrong data pipeline skills: Kafka/Kinesis or equivalent, exactly-once/idempotent processing patterns, and schema evolution.\nSolid AWS experience (EKS or Lambda, DynamoDB, S3, IAM) and infrastructure-as-code (Terraform/CDK).\nRigor around API design, testing, observability (metrics, tracing), and secure multi-tenant service patterns.\nNice-to-Have\nExperience with entity resolution, identity graphs, CDPs, or master data management.\nExposure to RAG systems or LLM-serving infrastructure.\nFamiliarity with Gremlin/openCypher/SPARQL query languages.\nExperience meeting compliance requirements (data residency, PII handling) in BFSI, healthcare, or telecom.","description_format":"text","description_chars":2795,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Speech & Audio AI","AI Consulting & Integration","Cloud Consulting & Migration"],"lifecycle":[{"event":"open","at":"2026-09-25T18:07:15Z"},{"event":"close","at":"2026-10-18T13:35:44Z"}],"visa":[],"liveness":null,"pay":null,"html_url":"https://alion.io/job/aivar-innovations-senior-software-engineer-knowledge-graph-retrieval-aiva","json_url":"https://alion.io/job/aivar-innovations-senior-software-engineer-knowledge-graph-retrieval-aiva.json","meta":{"generated_at":"2026-10-19T07:36:50Z","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":4925,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-20T00:00:00Z"}},"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":2036},"rest":"https://alion.io/mcp/rest/get_company?id=2036"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Faivar-innovations-senior-software-engineer-knowledge-graph-retrieval-aiva"},{"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%2Faivar-innovations-senior-software-engineer-knowledge-graph-retrieval-aiva"},{"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%2Faivar-innovations-senior-software-engineer-knowledge-graph-retrieval-aiva"},{"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/aivar-innovations-senior-software-engineer-knowledge-graph-retrieval-aiva\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Faivar-innovations-senior-software-engineer-knowledge-graph-retrieval-aiva"}]}
