As we integrate DryvIQ’s technology into the Nasuni platform, we’re looking for a Principal Database Engineer with deep ClickHouse expertise to architect and scale the analytical database infrastructure powering customer reporting and data intelligence.\nOur customers rely on flexible, self-service reporting to analyze their data, applying their own filters, groupings, and queries. As data volumes grow from hundreds of millions to billions-and potentially tens of billions-of records, delivering fast, reliable reporting becomes an increasingly complex engineering challenge. We need someone who can design ClickHouse architectures that perform at scale, not simply optimize individual queries.\nOur architecture uses PostgreSQL as the transactional system of record, with data replicated into ClickHouse to power customer-facing analytics and reporting. While PostgreSQL is well established, ClickHouse represents our greatest opportunity to improve performance, scalability, and the customer experience. The challenge is designing efficient data models, ingestion pipelines, and query strategies that deliver responsive reporting even as data volumes and query complexity increase.\nIn this hands-on, design-focused role, you’ll take technical ownership of ClickHouse architecture, data modeling, ingestion, replication, and query performance. You’ll work closely with application, platform, and infrastructure engineers to make critical architectural decisions, solve complex performance challenges, and build a scalable foundation for future growth.\nThis is not a traditional DBA maintenance role or an application development position.About the role\nNasuni acquired DryvIQ to expand its data intelligence and governance capabilities, and we're now integrating the DryvIQ platform into Nasuni. PostgreSQL is the system of record, holding the state of every item. That data is replicated into ClickHouse, which powers all customer reporting through a flexible web UI where customers build their own queries.\nPostgreSQL runs well today. ClickHouse is where the biggest challenge, and the biggest opportunity, lives. You'll take technical ownership of how data is modeled, laid out, and queried across the whole system, working side by side with application, platform, and infrastructure engineers. This is a design-first, hands-on role. \nWhat you'll do\nDesign, implement, and optimize ClickHouse databases supporting billions to tens of billions of rows of analytical data.\nMake architectural decisions involving ClickHouse table engines, MergeTree-family configurations, materialized views, projections, partitioning, sorting keys, and data layout.\nDesign efficient schemas for high-dimensional reporting workloads, including exceptionally wide tables approaching 1,000 columns.\nOptimize analytical SQL queries, query execution, and customer-facing reporting performance.\nEngineer and improve data ingestion, replication, and log collection workflows.\nEvaluate tradeoffs among query latency, ingestion throughput, data freshness, storage efficiency, and cost.\nDiagnose bottlenecks across databases, ingestion pipelines, and application-generated SQL.\nCollaborate with application engineers to understand ORM-generated queries and improve database access patterns without requiring application coding.\nEstablish performance benchmarks, monitoring, capacity planning, and scale-testing practices.\nUse approved AI-assisted tools for investigation and analysis, validating recommendations for correctness, security, and performance.\nWhat you'll bring\nMust-Have Qualifications\nDeep hands-on experience designing, implementing, tuning, and operating ClickHouse in production.\nStrong knowledge of ClickHouse table engines, particularly MergeTree-family engines, materialized views, and projections.\nDemonstrated experience designing analytical databases for billions of rows, with ownership of architectural and performance decisions.\nAdvanced SQL, query optimization, execution analysis, and data modeling expertise.\nExperience with large-scale ingestion pipelines, replication architectures, or analytical processing workflows.\nAbility to balance ingestion performance, query responsiveness, freshness, and infrastructure efficiency.\nExperience diagnosing production performance issues and delivering measurable improvements.\nAbility to read application code, understand database access patterns, and collaborate with software engineers.\nPreferred Qualifications\nPostgreSQL as an OLTP system of record, or comparable Oracle, SQL Server, or other relational OLTP experience.\nExperience with exceptionally wide analytical tables, including hundreds or approximately 1,000 columns.\nFamiliarity with ORM frameworks and inefficient application-generated SQL.\nDistributed ClickHouse, replication, sharding, and high-availability configurations.\nCustomer-facing SaaS analytics or reporting environments.\nDatabase observability, performance automation, and capacity modeling.\nNice to have\nExperience scaling databases to hundreds of terabytes or beyond.\nExperience supporting database-intensive SaaS products and C#/.NET application teams.\nFamiliarity with Linux and Kubernetes-based production environments.\nExperience with database automation, capacity modeling, and large-scale performance testing.\nClickHouse certification.\nIdeal Candidate\nHas personally designed and optimized production ClickHouse environments at multi-billion-row scale, understands analytical architecture tradeoffs, and can demonstrate measurable improvements in query responsiveness. Takes ownership of complex decisions and collaborates across ingestion, database, and application teams.\nExperience Guidelines\nTypically 9+ years in database engineering, data infrastructure, or related software engineering, including substantial recent hands-on ClickHouse production experience. Direct ClickHouse expertise, architectural ownership, and performance outcomes matter more than an exact number of years or a specific OLTP database.\nAbout Nasuni and Hyderabad\nNasuni is the unstructured data foundation for enterprise teams, and the AI that supports them.
