Who We Are

RCG, Inc. is a growing federal contracting company proudly Certified™ as a Great Place to Work® for four consecutive years. We provide innovative technology and cybersecurity solutions supporting complex federal government environments.

The Opportunity

RCG is seeking a Senior AI/Cybersecurity Solutions Engineer to support a federal Security, Architecture, and Engineering (SAE) team in Suitland, MD. This is a hands-on senior engineering role for an experienced professional who combines generative and agentic AI engineering, cloud security, cybersecurity automation, and federal compliance expertise. The selected candidate will help drive an agentic AI security platform, develop and harden automation supporting NIST 800-53 security assessments and remediation workflows, and take ownership of technical workstreams from requirements and implementation through CI/CD, deployment, and evidence generation. The ideal candidate will be equally comfortable developing Python-based AI automation, working with AWS security services and IAM, implementing secure cloud solutions, and maintaining the technical documentation and project traceability required in an auditable federal environment.

What You’ll Do

AI & Security Automation

• Design and implement Amazon Bedrock agent action groups, including OpenAPI schemas and Python Lambda execution layers.
• Develop Retrieval-Augmented Generation (RAG) pipelines using Bedrock Knowledge Bases with sources such as NIST 800-53, CIS Benchmarks, organizational System Security Plans (SSPs), and threat intelligence.
• Engineer prompts, guardrails, and input validation to improve AI accuracy, security, and resistance to prompt-injection attacks.
• Evaluate and evolve foundation-model strategies as AI capabilities and platform requirements mature.
• Develop AI-assisted capabilities supporting security assessment, remediation, hardening, alert triage, and compliance workflows.

Cloud & Cybersecurity Engineering

• Build automated NIST 800-53 control assessments and security evidence collection capabilities.
• Develop remediation and hardening automation across AWS services, including S3, EC2, IAM, CloudTrail, ECS, and EKS.
• Integrate live data from AWS Security Hub, GuardDuty, Inspector, and Config to support environment-aware security analysis and AI-assisted decision-making.
• Support BOD 26-04 SLA logic, CISA KEV correlation, risk enrichment, and remediation SLA tracking.
• Support security telemetry aggregation and integration with SIEM technologies, including Microsoft Sentinel and AWS Security Lake.

Container & Software Supply Chain Security

• Support ECR vulnerability scanning, EKS runtime monitoring, and container configuration hardening.
• Develop and analyze Software Bills of Materials (SBOMs) using formats such as SPDX and CycloneDX.
• Correlate vulnerabilities with the CISA Known Exploited Vulnerabilities (KEV) catalog to support risk-based prioritization.
• Perform dependency, provenance, and software supply-chain security checks, including detection of typosquatting and unsigned container images.

Platform Engineering & Delivery

• Maintain GitLab CI/CD pipelines supporting linting, testing, security scanning, builds, and deployments.
• Implement secure OIDC-based AWS authentication.
• Develop and manage Infrastructure as Code using CloudFormation and/or Terraform with least-privilege IAM.
• Support deployment and rollout verification across application and Kubernetes/EKS environments.
• Maintain strong Git practices, including branching, merge requests, and clean version-control history.

Documentation, Compliance & Technical Leadership

• Manage engineering work through Jira, maintaining accurate tickets, epics, sub-tasks, workflows, status, and handoffs.
• Maintain Confluence documentation, including architecture guides, runbooks, decision records, and onboarding materials.
• Produce technical design documentation, evidence packages, and other artifacts capable of supporting federal security assessments and audits.
• Maintain traceability between requirements, engineering work, code, deployments, and security evidence.

Take primary ownership of assigned technical workstreams and collaborate closely with cybersecurity and engineering team members.
