Dev Ops / Infrastructure Engineer – Guidehouse

Guidehouse is seeking a Dev Ops / Infrastructure Engineer cloud developer to join our Technology / AI and Data team, supporting mission‑critical initiatives for Defense and Security clients. In this role, you will lead the design, deployment, and automation of secure, scalable cloud infrastructure that powers advanced AI‑driven platforms.

• Lead architecture, deployment, security, automation, and monitoring of AWS Gov Cloud infrastructure supporting the FBI adjudication AI platform.
• Lead development of GPU‑accelerated EKS clusters, secure containerized model‑serving environments, distributed inference gateways, vector databases, and high‑throughput ingestion pipelines.
• Own the platform’s Dev Sec Ops  toolchain including CI/CD automation, IaC, secure pipelines, logging/monitoring integrations, and identity‑boundary enforcement aligned with federal requirements.
• Ensure 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 Gov Cloud 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, implement VPC designs with 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/Cloud Formation 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.
• 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 Cloud Trail, Cloud Watch, Guard Duty, Config Rules, and SIEM integrations.
• Support SSP documentation, boundary diagrams, control‑implementation statements, and continuous monitoring filings for the FBI ATO process.
• Enable LLM‑serving frameworks (vLLM, TGI, Sage Maker, Deep Speed) 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 with AI/ML engineers, backend developers, security engineers, and the solutions architect to align infrastructure with platform requirements.
• Mentor engineers in AWS Gov Cloud operations, Kubernetes, Dev Sec Ops , 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.

• An active and maintained TOP SECRET federal or DoD security clearance; obtain and maintain TS/SCI clearance.
• Minimum six (6) years of cloud/Dev…
