Accenture Federal Services is seeking a Database Engineer with Accumulo experience to join our team and support our client in San Antonio, TX. You will be a hands-on Database Engineer/Administrator specializing in Apache Accumulo within a distributed big data ecosystem. This role is critical to the sustainment, performance, security, and modernization of the customer's data platform. We are looking for a specialist fluent in Accumulo internals, HDFS, Zookeeper, YARN, and secure, large scale distributed data environments.

Accumulo Administration & Engineering

• 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.

What You'll Need

• 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
