Concept Plus is seeking a PostgreSQL Database Administrator (DBA) with at least 7 years of database engineering and administration experience to support a mission-critical, enterprise-scale client application. This role focuses heavily on Postgres SQL performance optimization, schema design, database reliability, and support for PGLite deployments—used to enable disconnected, low-bandwidth, and DDIL (Denied, Degraded, Intermittent, Limited) operations. The ideal candidate brings strong expertise in secure database operations, Cloud One environments, Zero Trust practices, and DevSecOps-aligned data management. What you’ll do Core PostgreSQL Administration: Administer, configure, and optimize PostgreSQL databases for secure DoD applications. Design, maintain, and version‑control Postgres SQL schemas, stored functions, triggers, indexes, roles, and extensions. Conduct advanced SQL optimization: query tuning, indexing strategies, partitioning, and performance diagnostics. Monitor and resolve database issues including slow queries, lock contention, replication concerns, and latency. Maintain secure backup/restore strategies and participate in continuity of operations (COOP) planning. Support ingestion and stabilization of inherited databases during transition‑in activities. PGLite / DDIL Data Operations: Manage and maintain PGLite (embedded PostgreSQL) instances used in disconnected or low‑connectivity operational environments. Support synchronization strategies between PGLite and central PostgreSQL systems, ensuring data integrity during DDIL conditions. Troubleshoot data serialization, compression, and synchronization workflows for offline‑first usage. Assist with field deployment preparation, including performance testing, data seeding, and reliability validation for PGLite nodes. DevSecOps & CI/CD Integration: Integrate database migration scripts, schema validations, and regression checks into secure CI/CD pipelines. Address SAST/DAST/SCA scan findings related to database components, SQL vulnerabilities, and ORM/library exposures. Collaborate with DevSecOps teams to enable secure, automated deployments and database lifecycle operations. Support build packaging, release readiness, and participation in JITC/DT&E test cycles. Security, Compliance & ATO Responsibilities: Apply DoD cybersecurity frameworks (NIST SP 800 53, 800 7, CMMC, DISA STIGs) to secure PostgreSQL environments. Implement and enforce database encryption (in transit and at rest), auditing, logging, and least privilege access controls. Document and remediate vulnerabilities, maintain POA&Ms, and support ongoing ATO compliance. Maintain secure handling of PII, PHI, and CUI across all database operations. Maintain and enhance database structures supporting integrations across TBLD M, TMDS, OMDS, MedCOP, and other JOMIS systems. Support data ingestion, transformations, and exchange based on ICDs and system‑to‑system interface requirements. Troubleshoot data flow issues and collaborate with cross functional development teams. Additional Responsibilities: Maintain database operational documentation including runbooks, installation guides, upgrade steps, and migration procedures. Support Tier 1–3 troubleshooting during integration testing, fielding events, and production operations. Participate in Agile ceremonies: planning, stand‑ups, backlog refinement, sprint reviews, and retrospectives. Collaborate across multi‑vendor teams, government stakeholders, and cloud/security engineering groups. Contribute to risk identification, performance tuning, and continuous improvement initiatives. Required Qualifications Ability to obtain and/or maintain a government clearance. 7+ years of professional PostgreSQL administration experience, including secure production environments. Experience managing PGLite or embedded PostgreSQL databases for offline or DDIL operations. Strong understanding of schema design, normalization, indexing, partitioning, query tuning, and database performance optimization. Experience managing PostgreSQL in cloud environments such as Cloud One, AWS GovCloud, or OCI. Hands‑on experience with schema versioning tools and migration frameworks aligned with MOSA principles. Familiarity with DevSecOps practices and integration of database components into CI/CD pipelines. Experience supporting secure environments governed by DoD cybersecurity and ATO requirements. Strong analytical, troubleshooting, and documentation skills. Ability to work collaboratively across multi‑vendor and government‑integrated teams. Preferred Qualifications Experience with the Cloud One platform. Experience supporting OPMED systems · Familiarity with Defense Health Agency systems such as (OMDS, MedCOP, MHS GENESIS). Experience with micro‑frontend architecture. Familiarity with GraphQL and Apollo Client. Contributions to open‑source projects or a demonstrable public portfolio.
