Job description

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.

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

Skills that matter: Advanced SQL, PostgreSQL and MySQL at production depth, including replication and backup strategy, Migration discipline, Data modeling for messy real-world intelligence corpora, not textbook examples, Index strategy and capacity planning, Python for data-layer tooling and migration scripting.

Tools you will use: PostgreSQL 15, MySQL 8, Python migration tooling, pgAdmin / DBeaver with query-plan discipline.

Location: New Delhi (HQ), E4, Vasant Vihar. Type: full-time permanent. Availability: immediate, rolling intake. Compensation: discussed at screening.
