About the role

Platform Engineer

We are looking for a platform infrastructure engineer to design, build, and operate cloud-native infrastructure for deploying AI workloads safely and reliably at scale.

AI systems — including autonomous agents, model-serving pipelines, and long-running inference workloads — present unique infrastructure challenges: multi-tenant isolation, network security, container lifecycle management, and operational resilience. This role owns the Kubernetes platform layer that makes safe cloud deployment of these workloads possible.

In this role, you will design container architectures for security-sensitive and multi-tenant environments, implement network policies and access controls for workload isolation, build CI/CD pipelines for reliable deployment, and establish infrastructure-as-code practices for reproducibility and auditability. You will work closely with AI engineers, while keeping the primary focus on the platform itself — making it secure, scalable, and operationally excellent.

Beyond immediate needs, you will help establish platform infrastructure best practices that can be applied across the firm’s broader cloud-native footprint.

Qualifications

BS + 5 years or MS + 3 years in a platform/infrastructure/DevOps engineering role

Deep hands-on experience with Kubernetes (EKS preferred) — cluster design, networking (CNI, service mesh), RBAC, and security policies

Strong AWS expertise — VPC architecture, IAM, ECS/EKS, networking, and security groups

Proficiency with Infrastructure-as-Code tools such as Terraform, CloudFormation, or Pulumi

Experience designing container architectures for multi-tenant or security-sensitive workloads

Familiarity with GitOps workflows and CI/CD platforms (ArgoCD, GitHub Actions, Jenkins)

Python and/or Go for tooling and automation

Technical leadership — ability to drive architectural decisions and mentor others

Desire to deliver cutting edge infrastructure in a fast-moving environment

Stay up-to-date with the latest advancements in cloud-native infrastructure, container security, and AI workload deployment

Nice to have

Familiarity with AI infrastructure —agent orchestration frameworks, MCP

Experience in the financial domain — regulated environments, compliance-aware infrastructure

Experience with container orchestration platforms for autonomous or long-running AI workloads

Prior experience securing production AI agent workloads at scale
