GMS Advisors is recruiting for its client, whose Trading Cloud team builds and operates the cloud infrastructure platform powering trading technology. The Senior AWS Cloud Infrastructure Engineer will own technology domains end-to-end, lead greenfield AWS platform buildouts, establish infrastructure-as-code and CI/CD standards, troubleshoot hybrid connectivity, mentor engineers, and support security, compliance, and production operations.
Responsibilities
- Own one or more technology domains end-to-end — such as the AWS multi-account landing zone ( Control Tower, SCPs, Organizations, IAM Identity Center ), EKS greenfield buildout (service mesh, GitOps/ArgoCD , Karpenter), CI/CD pipeline architecture, or AI/ML infrastructure ( Bedrock, GPU workloads, MLOps )
- Lead platform buildouts from design through production — architect, implement, and operate the systems your domain covers, making and documenting architecture decisions within your scope
- Author and enforce IaC standards — write production-grade Terraform/Terragrunt modules and establish patterns the entire team adopts
- Design and implement CI/CD pipelines for infrastructure and application workloads using Jenkins on ECS and GitOps workflows
- Understand and troubleshoot hybrid connectivity across co-location facilities, AWS Transit Gateway, Direct Connect, and cross-region networking; partner with the Networks team to resolve issues and implement changes
- Mentor two Mid-level Engineers — review code and designs, pair on complex problems, drive their technical growth
- Collaborate with the Governance and Security SME on security posture, vulnerability remediation prioritization, and regulatory compliance
- Participate in on-call as a senior escalation point for production infrastructure incidents
- Leverage AI-assisted developer tooling to accelerate delivery and reduce operational toil across the team
Skills
- 6+ years building and operating production infrastructure on AWS
- Deep expertise in at least one of: AWS multi-account architecture (Control Tower, SCPs, Organizations, TGW) or Kubernetes at scale (EKS, service mesh, GitOps/ArgoCD, Karpenter)
- Terraform and Terragrunt proficiency — you write modules, not just consume them
- CI/CD pipeline design and maintenance (Jenkins, GitHub Actions, or equivalent)
- Linux systems administration (Amazon Linux, RHEL, or equivalent)
- Python and Bash scripting for automation
- Experience mentoring engineers through code reviews, design reviews, and pairing
- Ability to take ambiguous problems and deliver without hand-holding
- Financial services, trading technology, or regulated industry experience
- Experience with Microsoft Entra ID (Azure AD) — enterprise application management, SAML/SSO configuration, and AWS IAM Identity Center integration
- Hybrid cloud connectivity troubleshooting (Direct Connect, Transit Gateway, co-location to AWS)
- Privileged access management (CyberArk or equivalent)
- Cloud security tooling (Wiz, Qualys, CrowdStrike)
- AI/ML infrastructure — Bedrock, SageMaker, GPU instance management, MLOps pipelines
- AWS certifications (Solutions Architect Professional, Advanced Networking, Security Specialty)
Benefits
- REMOTE / remote work arrangement
- Greenfield infrastructure engineering with direct impact on how capital markets technology runs
- Own a technology domain with real autonomy on a tight, high-caliber team
