About the Role We’re looking for a Solutions Architect to join our Professional Services team. You’ll work directly with enterprise customers to design, deploy, and optimize production‑grade AI infrastructure and agent systems. You’ll be responsible for architecting scalable, secure infrastructure deployments and building reliable, well‑evaluated agent applications that solve real business problems.

This role combines software development, infrastructure/platform engineering, and customer‑facing skills. You’ll work on everything from Kubernetes cluster design to multi‑agent system architecture, requiring deep technical expertise across both infrastructure and agent engineering domains.

This role offers direct impact on customer success, the opportunity to shape best practices, and work with cutting‑edge AI technology. You’ll join a collaborative team environment with a strong engineering culture.

Key Responsibilities

Infrastructure & Platform Engineering : Design scalable, highly‑available infrastructure for AI platform deployments (compute, storage, networking, security), enterprise integration patterns, Infrastructure as Code (Terraform, Helm), multi‑region HA/DR strategies, and CI/CD pipelines

Agent Engineering & Development : Design multi‑agent systems using different patterns, implement agent logic using modern frameworks (langchain/langgraph), design comprehensive evaluation frameworks, optimize prompts with A/B testing, and guide deployment/operations

Customer Engagement & Assessment : Lead technical maturity assessments, work directly with enterprise customers to understand requirements and present recommendations, and partner with Engagement Managers and Product/Engineering teams
