# Database Administrator Internship at CryptoMize Apply now for the Database Administrator Internship in Delhi at CryptoMize — a 6-month certified program on a rolling, always-hiring intake. Database Administrator interns here do not babysit a test database: from the first month you work on the PostgreSQL infrastructure behind our intelligence platforms — the electoral corpora, sentiment archives, and OSINT stores that serve engagements across 18 countries — under the standards our 99.9999%-uptime reputation is built on. You will learn backup and recovery on systems where data loss is not an inconvenience, and security hardening on databases that hold client-adjacent intelligence. If you want your DBA foundation laid where availability and confidentiality are the product, this is the description, the skills, the eligibility, and the selection process, in full. ## Facts - Location: New Delhi (HQ), CDR Building, Chhatarpur - Type: 6-month internship, certification provided - Availability: immediate, rolling intake (always hiring) - Compensation: discussed at screening ## What you will actually do - Support the PostgreSQL infrastructure behind our intelligence platforms — the stores our analysts and strategists query every day - Learn and execute backup, recovery, and restoration drills to the standard a 99.9999%-uptime operation demands - Monitor performance and manage parameters — indexes, query plans, capacity — on live corpora under senior DBA supervision - Implement access control and security hardening: role management, least-privilege grants, and audit logging on sensitive stores - Support database design reviews for new engagement data — schema suggestions reviewed by senior DBAs before anything ships - Document everything: runbooks, recovery procedures, and the incident notes that make outages teachable instead of repeatable - Sit the change-review rotation: every schema or configuration change on the estate is reviewed before it ships, and interns join that review from month two - Learn the analysts\' perspective: the queries you optimize serve the forecasting record the company quotes — meet the people behind the workloads ## Skills - SQL depth — beyond queries: plans, indexes, and why a statement is slow - PostgreSQL fundamentals — configuration, roles, replication basics - Backup and recovery discipline — tested restores, not assumed ones - Security mindset — least privilege, audit trails, access review - Performance monitoring literacy — reading what the database is telling you - Shell comfort — operating inside Linux servers without fear - Schema design fundamentals — normalization judgment and its limits - Documentation craft — runbooks another engineer can follow at 3 a.m. - Incident composure — diagnosing under pressure without making it worse - Confidentiality — these databases hold client-adjacent intelligence; discretion is structural - Capacity foresight — noticing the corpus that will outgrow its storage before the alert fires - Scripting basics — automation is the difference between an operator and an engineer ## Tools - PostgreSQL 15 (primary platform) - pg_dump / pgBackRest-class backup and restore tooling - Linux shell and systemd service management - pgAdmin / psql monitoring workflows - Query-plan analysis (EXPLAIN ANALYZE discipline) ## Questions and answers ### What does a Database Administrator intern do at CryptoMize? A Database Administrator intern supports the PostgreSQL infrastructure behind our intelligence platforms — running backup and restore drills, monitoring performance, implementing access control and hardening, and documenting runbooks — all under senior DBA supervision on systems where uptime and confidentiality are the product. By month six you will have restored a database under drill conditions; most DBA careers start years later than that. ### What is the eligibility for the Database Administrator Internship? Final-year students and recent graduates with strong SQL, Linux comfort, and genuine interest in database internals — people who read an EXPLAIN ANALYZE output for fun. No diploma is mandatory — we evaluate a practical SQL-and-diagnosis exercise, not paperwork (clinical-licensed roles are the only exception). ### Is the Database Administrator Internship paid? Compensation is discussed during the screening process and depends on demonstrated skill, engagement classification, urgency, and track record. We deliberately do not publish figures — every intern is evaluated and compensated individually. ### How long is the internship, and is a certificate provided? The program runs 6 months at our New Delhi HQ, with a certificate provided on completion — and hands-on production-adjacent DBA experience most freshers never touch. Strong interns receive full-time offers. ### What is the selection process for a Database Administrator intern? A short application form, a practical exercise (SQL depth plus a slow-query diagnosis), and a final interview with the infrastructure lead. The cycle typically completes within two weeks. ### Which database platform will I work on? PostgreSQL is the primary platform — the stores behind our intelligence estate. The fundamentals (backups, security, performance) transfer to every serious database you will ever meet. ### Will I touch production databases as an intern? Through supervised operations and drill environments built from production replicas — never unsupervised. The estate behind live intelligence work is protected by change review, but the skills transfer exactly: by month six you will have executed every core operation a production DBA owns.
