About The Position

Resource Management Concepts, Inc. (RMC) is seeking a Senior Database Engineer with systems programming expertise and a strong background in database engineering. The role focuses on understanding database engines and core services internally, including examining source code and network communications and modifying software to support mission requirements. The engineer will trace behavior through unfamiliar codebases and protocols, identify appropriate integration points for changes, and assess effects across an integrated technology stack.

The position involves developing and maintaining secure, scalable applications and services; building systems-level and networked software; engineering relational and graph data solutions; and working across databases, object storage, and search technologies. Responsibilities also include infrastructure automation, cloud deployment and operations, identity and access integrations, Zero Trust design, security collaboration, and maintaining technical and operational documentation.

This full-time position is on-site at a Government facility in Charleston, South Carolina. It is contingent on contract award and position availability.

• Typically 10 years of professional software engineering experience.
• Active TS/SCI clearance and ability to obtain a CI polygraph.
• Prior Intelligence Community support experience.
• Experience designing, administering, and optimizing PostgreSQL and Neo4j, and integrating them with applications.
• Professional or academic experience with programming and Agile, DevOps, or DevSecOps.
• Hands-on C, C++, or Rust systems programming and ability to learn additional languages.
• Experience with OS interfaces, processes, IPC, concurrency, multithreading, synchronization, signals, and memory and resource management.
• Experience with socket-based communications, database internals, network protocols, or comparable low-level code analysis.
• Ability to trace unfamiliar code and assess performance, interoperability, concurrency, and security impacts.
• Experience with relational database design, SQL, query optimization, and access controls; understanding of graph databases.
• Experience with infrastructure automation and cloud deployments.
• Experience with OIDC, authentication, authorization, and Zero Trust components (PDP, PAP, PIP, PEP).
• Strong troubleshooting, documentation, and collaboration skills.
• Agile Developer or Certified Scrum Developer certification.
• Security+ or higher-level cybersecurity certification.

Nice To Haves

• Master’s degree in a related quantitative field.
• Experience with packet analysis, binary formats, protocol parsers, or database client/engine modifications.
• Experience with Terraform and Ansible for provisioning, configuration, and deployment.
• Experience with AWS/GovCloud, Kubernetes, OpenShift, and DoD IL5 environments.
• Experience with PingFederate, Keycloak, Radiant Logic, SailPoint, Secret Server, or Okta; identity-provider migrations and related code changes.
• Experience with PKI, certificate/key management, validation, and cryptographic integrations.
• Experience with PKCS #11 integration with cryptographic tokens, HSMs, or secure key storage.
• Experience in cryptographic implementation, evaluation, or integration, including ML-KEM.
• Experience with TDF, Go-based security services, enterprise integration, or Protocol Buffers.

Responsibilities

• Develop, maintain, test, and deploy secure, scalable applications and services using languages such as C, C++, Rust, Go, Java, Python, or Node.js.
• Apply systems programming principles, particularly in C, C++, and Rust, to build performant and reliable software components.
• Develop software supporting process creation, monitoring, control, and inter-process communication.
• Build concurrent and multithreaded applications using appropriate synchronization, signal handling, memory management, and resource-control techniques.
• Design, implement, and troubleshoot networked applications using sockets, client-server architectures, and applicable network protocols.
• Analyze database-engine source code, communications protocols, request and response formats, serialization, and packet layouts to support development and integration.
• Trace requests through database-engine code to identify processing logic, integration points, and the effects of proposed modifications.
• Develop relational data-storage solutions using SQL, including data modeling, query development, performance tuning, and access control.
• Develop and integrate graph database solutions for relationship-based data modeling, analysis, and retrieval.
• Work across relational databases, graph databases, object storage, and search/indexing engines, including PostgreSQL, Redis, RxDB, Neo4j, Amazon S3, and Elasticsearch.
• Refactor and modernize existing services, including transitioning functionality from Python to other implementation languages where appropriate.
• Develop and maintain Infrastructure as Code to provision, configure, and manage infrastructure through repeatable, version-controlled workflows.
• Deploy, monitor, and troubleshoot cloud-hosted software and its dependencies on compute, storage, networking, identity, and security services.
• Integrate applications with identity providers for authentication, authorization, federation, single sign-on, and identity-aware access control.
• Implement OpenID Connect integrations, including token validation, claims processing, client registration, redirect flows, session management, and secure API access.
• Incorporate Zero Trust Architecture principles, including interactions among policy decision, administration, information, and enforcement components.
• Collaborate with cybersecurity, infrastructure, data, and mission stakeholders to integrate security controls, cryptographic protections, logging, monitoring, and auditability throughout the software development lifecycle.
• Produce and maintain software designs, interface specifications, deployment procedures, configuration baselines, security implementation details, and operational support materials.

Benefits
