Job summary

Virima is seeking an seasoned Database Reliability Engineer to own PostgreSQL, MongoDB, and MySQL in a container-native, Kubernetes environment. You will design HA clusters, automate operations, and guide domain teams on optimal schema and query design while leading backup and disaster recovery with clear RPO/RTO targets.

You’ll implement multi-AZ replicas, read replicas, and connection pooling, optimize performance, and drive data modeling reviews with migration strategies.

Qualifications

• 5–8 years as a DBA/DBRE with production PostgreSQL, MongoDB, and MySQL experience.
• Strong Kubernetes fundamentals for stateful workloads (StatefulSets, PV/PVC, CSI).
• Deep skills in SQL, indexing, query plans, transactions, replication, and failover.
• Proven backup/restore ownership (PITR, cross-AZ/region replicas) with documented RPO/RTO.
• Hands-on with automation/IaC (Helm/Terraform/Ansible) and CI/CD for DB changes.
• Observability with dashboards, SLOs, alerting, and incident management.

Responsibilities

• Design and operate HA clusters on Kubernetes (StatefulSets, PDBs).
• Choose and operate DB operators/distributions and patching strategy.
• Implement multi-AZ replicas, read replicas, and connection pooling for scale.
• Performance optimization: capacity planning, latency, and throughput KPIs.
• Data modeling reviews, migration strategies, and query best practices.
• Backup, DR runbooks, quarterly game days, and compliance with RPO/RTO.

Role Overview

Own the reliability, availability, performance, and security of our databases—PostgreSQL, MongoDB, and MySQL—runningcontainer-native,highly availableonKubernetes.You’lldesign the architecture, automate operations, guide domain teams onoptimalschema & query design, and leadbackup/restore and disaster recovery (DR)with clear RPO/RTOobjectives.

WhatYou’llDo

Design andoperateHA clusters on Kubernetes (StatefulSets, PDBs, anti-affinity, topology spread, CSI storage, auto-failover).

Choose andoperateDB operators/distributions (e.g.,Zalando/Crunchy for Postgres,Perconafor MongoDB/MySQLor equivalents);maintainversioning/patching strategy.

Implement multi-AZ replicas,read-replicas, and connection pooling/proxying (e.g.,pgBouncer/HAProxy/Envoy) for scale.

Performance & Scalability

Capacity planning, sizing, and benchmarking; own p95/p99 latency and throughput KPIs.

Query/index tuning, VACUUM/ANALYZE/auto-analyzestrategies (Postgres), sharding/replica-set tuning (MongoDB), andInnoDB/Group Replication tuning (MySQL).

DataModeling& Reviews

Partner with domain teams onschema/design reviews, migration strategies (Flyway/Liquibase/Alembic), and query best practices to keep services fast and cost-efficient.

Backup, DR & Compliance

Ownbackup/restore(base backups, PITR/WAL/GTID, snapshotting),testedDR runbooks, and RPO/RTO targets; runquarterly game days.

Implement data retention, encryption (at rest & in transit), auditing, and access controls (RBAC/KMS/Secrets).

Automation & CI/CD

Everything-as-code: Helm/Terraform/Ansible for DB infra;GitOpspipelines for changes, safe rollout/rollback, and automated smoke checks.

Requirements

Minimum Qualifications

5–8 years as a DBA/DBRE withproductionexperience inPostgreSQLplusMongoDBandMySQL(at least two in depth).

Strong Kubernetes fundamentals for stateful workloads (StatefulSets, PV/PVC, CSI, network policies, PDBs).

Deep skills in SQL, indexing, query plans, transaction/locking, replication, and failover.

Provenbackup/restore & DRownership (PITR, cross-AZ/region replicas) with documented RPO/RTO.

Hands-on with automation/IaC(Helm/Terraform/Ansible) and CI/CD for DB changes.

Observability in practice (exporters, dashboards, SLOs, alerting) and rigorous incident management.

Excellent collaboration/communication; confident running schema/design reviews with product teams.

Preferred (Nice to Have)

Experience withpgBouncer,Patroni/Crunchy/Zalandooperators (Postgres),PerconaOperators(MongoDB/MySQL).

CDC and streaming (Debezium/Kafka/Pulsar), read-through caches (Redis), and read/write splitting.

Security hardening: TLS/mTLS, TDE/column encryption, secretsmgmt(KMS), auditing.

Compliance exposure (PII, GDPR/DPDP), data masking/tokenization.

Scripting (Python/Bash) for automation; chaos/testing tools for DR and failover.

Multi-tenancy patterns (schema vs. DB vs. cluster) and cost attribution.

Example Projects

Migrate a monolithic DB toread-replicas + connection poolingwith safe cutover and zero-downtime.

Stand upoperator-managed PostgreswithPITRand scheduled verification restores.

Design aMongoDB replica setorMySQL Group Replicationtopology with multi-AZ resilience and automated failover.

ImplementDebezium→(Kafka/Pulsar)for CDC to downstream analytics with backpressure and replay.
