Responsibilities

Serves as the lead cloud and DevOps engineer responsible for architecting, deploying, securing, automating, and monitoring AWS GovCloud infrastructure supporting the FBI adjudication AI platform.
Leads development of GPU-accelerated EKS clusters, secure containerized model-serving environments, distributed inference gateways, vector databases, and high-throughput ingestion pipelines.
Owns the platform’s DevSecOps toolchain including CI/CD automation, IaC, secure pipelines, logging/monitoring integrations, and identity-boundary enforcement aligned with federal requirements.
Ensures full FedRAMP High, RMF, and FBI ATO alignment across infrastructure controls, logging coverage, network segmentation, encryption, monitoring, and boundary configurations.
Design, deploy, and maintain secure AWS GovCloud architectures supporting LLM inference, retrieval services, vector databases, backend APIs, and large-scale document processing pipelines.
Build and manage GPU-accelerated EKS clusters including autoscaling node groups, GPU scheduling, operators, and optimization for high-performance inference workloads.
Architect multi-AZ high-availability patterns including health checks, failover mechanisms, and distributed storage strategies.
Implement VPC designs including private subnets, NAT gateways, VPC endpoints, NACLs, SGs, and traffic inspection layers supporting zero-trust boundaries.
Develop CI/CD pipelines automating build, scan, test, deploy, and rollback processes for AI services, APIs, UI applications, and data pipelines.
Use Terraform/CloudFormation for automated provisioning of networks, clusters, storage, identity boundaries, and monitoring components.
Embed SAST, SCA, IaC scanning, container scanning, dependency checks, and image attestation into pipelines to enforce supply chain security.
Automate promotion workflows across dev, staging, and production environments under controlled change-management policies.
Implement NIST 800-53, FedRAMP High, RMF, and CJIS controls across encryption, identity management, logging, monitoring, container hardening, and network segmentation.
Configure KMS key hierarchies, secrets management, token-scoped identities, certificate rotation, and workload identity policies.
Develop logging and monitoring pipelines using CloudTrail, CloudWatch, GuardDuty, Config Rules, and SIEM integrations.
Support SSP documentation, boundary diagrams, control-implementation statements, and continuous monitoring filings for the FBI ATO process.
Deploy and tune GPU compute environments using G-series or P-series instances optimized for hosting open-weight LLMs and retrieval workloads.
Enable LLM-serving frameworks (vLLM, TGI, Sagemaker, DeepSpeed-based endpoints) with secure gateways and autoscaling rules.
Support vector databases (FAISS, pgvector, Elasticsearch), embedding pipelines, retrieval services, and memory-optimized storage.
Optimize I/O throughput, caching, and container networking for large-scale investigative document ingestion.
Implement observability via metrics, traces, logs, health checks, SLOs/SLIs, and operational dashboards.
Improve reliability using circuit breakers, retry/backoff logic, blue/green deployments, canary rollouts, and automated remediation workflows.
Develop automated patching, hardened AMIs, OS-level security profiles, container runtime protections, and dependency management routines.
Ensure highly available infrastructure for adjudication workflows and continuous-vetting operations.
Collaborate closely with AI/ML engineers, backend developers, security engineers, and the Solutions Architect to ensure infrastructure aligns with platform requirements.
Mentor engineers in AWS GovCloud operations, Kubernetes, DevSecOps, IaC engineering, and cloud security best practices.
Participate in sprint planning, architecture reviews, troubleshooting sessions, and mission-support activities.
Ensure infrastructure performance, scalability, and reliability enable adjudicators to efficiently process high-volume investigative workloads.
