# Data Base Developer Job Opening at CryptoMize Data Base Developer jobs in Delhi at CryptoMize are open on a rolling, always-hiring basis — every intelligence product the agency ships stands on databases this role designs and hardens. This is a full-time, permanent position with immediate joining, based at our New Delhi HQ, building the data layer behind platforms and client engagements across all five Penta-P domains. A database is an organized collection of data — and in this house, organized means engineered: stable schemas, honest indexes, migrations that never eat a corpus. Below is the complete job description — responsibilities, requirements, the seniority path, and the selection process. ## Facts - Location: New Delhi (HQ), CDR Building, Chhatarpur - Type: full-time permanent - Availability: immediate, rolling intake (always hiring) - Compensation: discussed at screening ## What you will actually do - Design stable, reliable and effective databases for new platforms and engagement tooling — schemas that model the domain honestly and survive three years of scope drift - Optimize and maintain the legacy systems the agency still runs — measured, migrated, and documented, never big-banged - Modify databases to request: scope the change with the requesting cell, write and test the migration, ship it with a rollback path - Solve usage issues and malfunctions at the data layer — the lock, the plan regression, the silently corrupted index — before they become engagement incidents - Liaise with application developers to improve data access patterns and establish best practices that hold across teams - Own performance: query planning review, index strategy and capacity forecasting for multi-gigabyte intelligence corpora - Write the technical and training material so every database you build can be operated by someone who is not you ## Skills - Advanced SQL — schema design, window functions, query planning, performance tuning - PostgreSQL and MySQL at production depth, including replication and backup strategy - Migration discipline — versioned, reviewed, reversible - Data modeling for messy real-world intelligence corpora, not textbook examples - Index strategy and capacity planning - Python for data-layer tooling and migration scripting - Collaboration with application developers on access patterns and ORM hygiene - Security literacy — least-privilege access, encryption at rest, audit logging - Documentation and runbook writing - Requirements gathering from non-database stakeholders - Discretion with NDA-grade client datasets (non-negotiable) ## Tools - PostgreSQL 15 - MySQL 8 - Python migration tooling (Alembic-class) - pgAdmin / DBeaver with query-plan discipline - Git-reviewed schema repositories ## Questions and answers ### What are the requirements for Data Base Developer jobs at CryptoMize?
