Deployed Infrastructure Engineer

Job summary

Responsibilities

As a Forward Deployed Infrastructure Engineer at Sierra, and a founding member of this function, you will own the end-to-end lifecycle of customer deployments, while helping define how Sierra’s AI platform is deployed and operated across enterprise environments.

• Own deployment architecture conversations and execution — designing and implementing deployment strategies across customer environments, including VPC configuration…
• Manage the full infrastructure lifecycle for some of Sierra’s most critical customers: initial deployment, ongoing upgrades, scaling, and incident support.
• Develop and maintain deployment runbooks, upgrade procedures, and automation tooling to make operations repeatable and reliable.
• Partner with engineering teams to ensure Sierra's platform is deployable and operable across diverse customer requirements.
• Work with customers' platform engineering, security, and DevOps teams to navigate their infrastructure constraints and compliance requirements.

What they're looking for

• 4+ years of experience in infrastructure, DevOps, platform engineering, or solutions architecture roles — with significant time spent on customer-facing deployment work.
• Deep experience with AWS services, Terraform, container orchestration, and cloud networking (VPCs, IAM, DNS, load balancing).
• Track record of managing deployments in customer-owned cloud environments, including navigating security reviews, compliance requirements, and change management processes.
• Ability to navigate ambiguity with enterprise stakeholders — from platform engineers to CISOs — and turn infrastructure conversations into actionable deployment plans.
• Strong operational instincts: you think about upgrades, rollbacks, monitoring, and failure modes from the start, not as an afterthought.
