Experience required45 years

Location: Remote

BGV: Yes

Key Responsibilities

• Strong, handson experience managing productiongrade Apache Cassandra clusters
• Experience defining and enforcing Cassandra best practices, governance, and operational standards
• Ability to create detailed runbooks and SOPs for:
  • Node addition and removal
  • Cluster rebalancing
  • Repair operations
  • Version upgrades (experience with Cassandra 4.x required; upgrade planning to 5.x expected)
• Proven experience in Cassandra performance tuning, including: JVM tuning, Cache configuration, Thread pool and timeout tuning
• Strong understanding and handson ability to identify and resolve:
  • Hot partitions
  • Read/write amplification issues
  • High latency and failure scenarios
• Deep understanding of Cassandra architecture and internals
• Experience reviewing and optimizing:
  • Cluster topology (replication strategy, consistency level, etc.)
  • Disk, memory, and storage layouts
• Ability to define and maintain capacity planning guidelines based on data growth and workload patterns
• Handson experience setting up monitoring and alerting for Cassandra clusters
• Ability to monitor and alert on critical metrics such as:
  • Read/write latency
  • Read/write failures
  • Repair health
  • Disk usage and storage trends
• Experience defining and executing backup and restore strategies:
  • Snapshots vs incremental backups
  • Backup validation and restore drills
  • Ability to plan and execute DR simulations and ensure operational readiness
• Strong Linux fundamentals and troubleshooting skills
• Automation and scripting skills (Shell/Python)
• Experience operating Cassandra in cloud environments (AWS/GCP/Azure)

Preferred Skills

• Handson experience with Cassandra 5.x or largescale version upgrades
• Experience with infrastructure as code (Terraform, Ansible, etc.)
• Exposure to SRE practices (SLIs, SLOs, error budgets)
• Experience integrating Cassandra monitoring with tools like:
  • Prometheus & Grafana
  • Datadog, New Relic, or similar observability platforms
• Experience optimizing cost efficiency for largescale database operations
• Exposure to Kubernetesbased Cassandra deployments

Qualifications

• Prior experience on projects involving Cassandra.

Other Details

  • Node Addition/removal
  • Rebalancing
  • Repair operations
  • Version upgrade (we want to move from 4.1.3 to 5xx)
• Establish capacity planning guidelines
• Setup monitoring, alerting and observability for Cassandra DB:
  • Monitoring for latency, read/write failures, repair health, disk usage
• Current State Analysis and Tuning
• Deepdive review of existing setup
• Cluster topology (replication etc)
• Disk, memory, and JVM tuning
• Tune (JVM, Cache, Thread pool and timeout)
• Identify and fix:
  • Hot partitions
  • Read/write amplification issues etc
• Operation reliability and DR
• Define backup and restore strategy:
  • Snapshots vs incremental backups
  • Restore drills.
• Cost Efficiency in terms of Operating DB.
