## About the Role

* 5 years of experience working with distributed data systems and/or large-scale storage technologies
 * Experience with Accumulo and/or Hadoop and/or Zookeeper
 * DoD 8140 compliance (e.g. Security+, CISSP, CASP, etc.) or ability to obtain within 6 months

Bonus points if you have:

 * Experience with distributed systems architecture, data migration, and consolidation projects
 * Understanding of platform reliability and operational best practices

Clearance:

Must have an active TS/SCI level clearance

## Description

* Manage, configure, and optimize Accumulo clusters, including tservers, master, monitor, and garbage collector services.
 * Perform and tune Accumulo compactions, flush operations, and table-level maintenance routines.
 * Engineer, configure, and validate Accumulo tables, iterators, splits, security labels, and performance settings (tablet distribution, bloom filters, tserver configurations).
 * Troubleshoot and resolve complex Accumulo server errors, iterator issues, classloader problems, and runtime exceptions.

Distributed System Architecture

 * Configure and optimize the supporting Hadoop ecosystem, including HDFS, Zookeeper, and YARN, ensuring tightly paired but properly decoupled management where feasible.
 * Evaluate and tune distributed file system architecture for enterprise-scale ingestion, analytics, and storage workloads.

Security & Cell-Level Access Control

 * Implement and maintain Accumulo's cell-level security and read-path enforcement (Standard Read vs. Full Access modes).
 * Ensure strict compliance with CUI, TS/SCI, and cross-domain security requirements for data at rest and in motion.

Backup, Recovery, and Sustainment

 * Manage Accumulo-level and HDFS-level backup processes, automated backup directories, and restore procedures.
 * Work with multi-environment (NIPR/SIPR/JWICS) deployments following enterprise sustainment and modernization expectations.

Operational Diagnostics & Continuous Improvement

 * Analyze Accumulo logs and metrics to troubleshoot ingest failures, iterator misconfigurations, ZK/YARN dependencies, and scaling constraints.
 * Collaborate with engineering teams on evaluating modernization options and improving architectural resilience.
