Expert Database Administrator

Designation: System Database administrator

Location: Bangalore

Work Mode: Hybrid

Shift Time: 11:00 Am - 8:00PM IST

Introduction to the job

We’re building a production-grade, self-managed Enterprise MongoDB platform running hybrid cloud infrastructure. Today, our estate is a mix of single instances and replica sets. Over the next 12–18 months, we will standardize operations, expand automation/monitoring, and design the path toward a global standard with multi-site resiliency. This IC-track role is the expert technical owner who sets platform standards, leads complex production problem-solving, and mentors a developing operations team while partnering directly with internal customers and application teams.

Some Of the things you will be doing:

Scope & Authority (What you will own)

• Define and own MongoDB platform standards (build/config baseline, backup & restore validation, patch/upgrade strategy, monitoring & alert thresholds, and incident runbooks).
\n
• Lead technical direction for the roadmap to global standardization for MongoDB products (design decisions, operational model, and migration approach).
\n
• Act as the senior escalation point for complex MongoDB incidents and performance bottlenecks; drive post-incident RCA and systemic fixes.
\n
• Coach junior operations specialists and administrators to safely execute common tasks through documentation, checklists, and mentorship.
\n

Some of the things you’ll be doing

\n

Platform Engineering & Operations (Self‑Managed MongoDB on Nutanix VMs)

\n
• Own day-to-day production administration for single instances and replica sets: provisioning, configuration, upgrades, maintenance, and operational hygiene.
\n
• Define and enforce repeatable server build standards (naming, sizing, filesystem layout, access patterns, and environment parity across DEV/QA/UAT/PROD).
\n
• Partner with virtualization/infrastructure teams to ensure MongoDB VMs align with required OS/VM configuration guidance and operational constraints.
\n
• Implement a durable change process: risk assessment, rollback planning, communications, and CAB/change record readiness as required.
\n

Backup, Recovery, and Operational Tooling

\n
• Own backup and recovery strategy including routine restore tests and documented RPO/RTO expectations.
\n
• Operationalize tooling (., MongoDB Ops Manager or equivalent) for monitoring, automation, and backup where appropriate; standardize agent deployment and backup configuration.
\n
• Ensure backup/restore procedures are auditable, repeatable, and transferrable across the team.
\n

Performance Engineering & Capacity Planning

\n
• Lead advanced troubleshooting: slow queries, index strategy, aggregation pipeline performance, replication lag, storage/IO contention, and resource saturation.
\n
• Partner with application teams on document model design, query patterns, and index alignment to prevent collection scans and recurring performance issues.
\n
• Create evidence-based capacity plans and right-sizing recommendations (CPU/RAM/disk/IOPS/network) for MongoDB workloads on VMs.
\n

Security, Governance & Compliance

\n
• Implement and maintain MongoDB security controls appropriate to self-managed deployments (authentication, authorization/RBAC, TLS/transport security, audit posture).
\n
• Drive least-privilege access, credential lifecycle hygiene, and secure operational practices aligned with enterprise security expectations.
\n
• Partner with security stakeholders to support hardening baselines, evidence collection, and continuous compliance where required.
\n

Documentation, Mentoring & Customer Interface

\n
• Create and maintain runbooks, standards, and operational checklists to reduce key-person risk and enable safe delegation.
\n
• Mentor junior ops specialists/admins via structured enablement (pairing, lab walkthroughs, on-call coaching, and knowledge shares).
\n
• Provide crisp, customer-ready communications during incidents and major changes; translate deep technical decisions into clear plans.
\n

What success looks like (first 90 days)

\n
• Complete a current-state assessment (top reliability/security/performance risks; backup validation posture; upgrade/patch cadence; operational gaps).
\n
• Publish v1 platform standards (replica set baseline, backup/restore validation cadence, monitoring thresholds, incident/runbook library).
\n
• Deliver a 6–12 month roadmap toward automation maturity and sharding value and readiness (prereqs, design decisions, and operational requirements).
\n

What success looks like (6–12 months)

\n
• Reduced production incidents via systemic fixes, better monitoring, and operational standardization (lower toil, faster MTTR).
\n
• Clear, repeatable upgrade and change management motions with reliable rollback plans and stakeholder communications.
\n
• A trained support bench: multiple team members can execute routine operations safely using documented procedures.
\n
• A validated design and phased plan for sharding/multi-site resiliency, with readiness criteria and operational guardrails.
\n

What technical skills, experience, and qualifications do you need?

\n

Required Qualifications (Day‑1)

\n
• 12+ years in database engineering/administration with significant, recent hands-on MongoDB production ownership.
\n
• Strong experience operating self-managed MongoDB on Linux, including single instances and replica sets (elections/failover, replication health, recovery).
\n
• Demonstrated ownership of backup/restore, disaster recovery thinking, and routine restore validation.
\n
• Deep performance engineering capability (index strategy, query/aggregation analysis, replication lag triage, capacity planning).
\n
• Strong Linux/systems fundamentals relevant to running databases on VMs (storage, IO, CPU/memory, OS services, troubleshooting).
\n
• Excellent written and verbal communication; able to produce high-quality runbooks/standards and lead incident communications.
\n

Required Soft Skills

\n
• Comfort mentoring and leveling up junior administrators through structured coaching and documentation.
\n
• Strong customer/stakeholder orientation; sets expectations, explains tradeoffs, and drives work to closure.
\n
• Calm incident leadership and bias toward measurable outcomes.
\n

Preferred Qualifications (Bonus / Nice-to-have)

\n
• Experience with MongoDB Ops Manager (automation/monitoring/backup), including agent rollout and backup configuration.
\n
• Experience planning or executing a move toward sharded clusters and developing an operational model for sharding.
\n
• Infrastructure-as-code / automation experience (., Ansible/Terraform) and CI/CD patterns for operational workflows.
\n
• Observability tooling experience (metrics/log pipelines, alert tuning, dashboards) across database and host layers.
\n
• MongoDB certifications (optional): Associate Database Administrator / related credentials, or equivalent demonstrated expertise.
