About The Position

The Senior Oracle/MongoDB Database Administrator (DBA) is a senior-level technical and administrative role responsible for managing mission-critical database environments. This position will lead the design, capacity planning, installation, configuration, clustering, performance tuning, and monitoring of large-scale Oracle and MongoDB deployments. In addition, the role provides consultative support to development teams on database architecture, design, development best practices, and performance optimization — driving improvements in scalability, reliability, and operational efficiency. While the primary focus is on Oracle and MongoDB, experience with SQL Server or cloud-native database technologies (AWS, Azure, GCP, OCI or Atlas) is a plus.

Requirements

• Bachelor's or Master’s degree in Information Systems, Computer Science or a related field.
• 5+ years of hands-on Oracle DBA experience in enterprise-scale environments.
• 5+ years of experience with high availability (Oracle RAC, Data Guard, failover, replication).
• 5+ years of advanced SQL/PLSQL development and performance tuning.
• 5+ years of supporting developers with application design, query tuning, and schema optimization.
• 3+ years of hands-on MongoDB administration experience (replica sets, sharding, backups, monitoring).
• 3+ years of experience with Linux administration (shell scripting, system tuning, automation).
• Experience with automation frameworks (Ansible, BitBucket, Terraform, or similar).
• Experience with database monitoring and observability tools (OEM, SolarWinds/DPA, PMM, DataDog, Grafana).
• Exposure to cloud-native environments (AWS, Azure, OCI, or GCP).
• Familiarity with DevOps/CI/CD pipelines for database changes.

Nice To Haves

• Deep expertise with Oracle RDBMS internals (RAC, ASM, Data Guard, RMAN).
• Strong knowledge of MongoDB internals (replica sets, sharding, WiredTiger, security).
• Proficiency in SQL and PL/SQL coding and tuning.
• Proficiency in Linux system administration (shell scripting, performance tuning).
• Knowledge of networking fundamentals and how they affect distributed databases.
• Strong ability to gather, interpret, and document requirements.
• Excellent communication skills: oral, written, and presentation.
• Strong interpersonal and customer service skills; proven ability to collaborate across teams.
• Exceptional time management, prioritization, and organizational skills.

Responsibilities

• Design, install, configure, upgrade, and maintain Oracle and MongoDB databases across multiple environments.
• Plan, allocate, and manage system storage, ensuring future scalability.
• Create and manage core database objects and structures.
• Implement and maintain database security, user access, and role management.
• Develop and maintain physical data models and enforce database standards.
• Proactively monitor and tune databases for performance, scalability, and reliability.

• Implement archiving solutions and lifecycle management for data retention.
• Analyze and document database infrastructure, hardware, and technology requirements.
• Partner with development teams to review code and design for performance, scalability, and alignment with best practices.
• Provide expert-level troubleshooting and root cause analysis for database-related incidents.
