Full Job Description
The Role:

In this role you'll define the technical direction for the infrastructure platform powering automated manufacturing across multiple factory sites. You'll shape the architecture spanning cloud, edge, and factory-floor systems, setting the standards, patterns, and engineering culture that the entire organization builds on. You'll move fluidly between strategy and implementation: one day driving a multi-cluster Kubernetes architecture decision, the next pairing on a Terraform module that makes it real. This role demands someone who has simplified complex systems at org scale, built platforms that engineers love to use, and grown the people around them. Not just shipped impressive infrastructure, but made everyone else's infrastructure better too.

What You'll Do
  • Design and implement cloud infrastructure on AWS using Terraform/OpenTofu
  • Build and manage Kubernetes clusters (EKS in cloud, K0s/K3s at the edge)
  • Build CI/CD pipelines and GitOps workflows with GitHub Actions and ArgoCD
  • Develop reusable infrastructure patterns: Terraform modules, Helm charts, CUE schemas
  • Architect networking between sites, edge devices, and cloud
  • Implement monitoring and observability with Prometheus/Grafana and Datadog
  • Support edge computing and IoT device deployments on factory floors
  • Drive build-vs-buy decisions and technology evaluations
  • Establish engineering standards and best practices
  • Represent infrastructure in cross-functional architecture reviews
  • Make architecture decisions under ambiguity and document them as ADRs
  • Identify systemic operational gaps and drive automation that eliminates recurring toil
  • Participate in on-call rotation and incident response
  • Write clear documentation and runbooks


What We're Looking For
  • 10-15+ years in infrastructure or platform engineering
  • Expert-level infrastructure design across cloud, containers, and networking
  • Can go from architecture whiteboard to production implementation, and has done it repeatedly
  • Deep Terraform/IaC skills with module development and testing experience
  • Production Kubernetes experience including troubleshooting, scaling, and multi-cluster patterns
  • Strong security instincts: threat modeling, least privilege, compliance fundamentals
  • Track record of building reusable patterns that other engineers adopt
  • History of reducing complexity, not just adding capability
  • Strong documentation and communication skills
  • Comfortable mentoring teammates and sharing knowledge


What Will Set You Apart
  • Experience defining infrastructure strategy and technical direction for an engineering org
  • Track record of driving platform adoption across multiple teams without direct authority
  • Background operating at scale: multi-site deployments, 20+ consuming teams, or similarly demanding environments
  • History of mentoring senior engineers into technical leaders
  • Deep experience with architecture trade-offs in hybrid cloud/edge environments
  • Demonstrated ability to simplify systems and retire tools that no longer serve the org


Compensation

For this role, the target salary range is $250,000 - $320,000(actual range may vary based on experience).

This is the lowest to highest salary we reasonably and in good faith believe we would pay for this role at the time of this posting. We may ultimately pay more or less than the posted range, and the range may be modified in the future. An employee's pay position within the salary range will be based on several factors, including, but not limited to, relevant education, qualifications, certifications, experience, skills, geographic location, performance, and business or organizational needs.

Benefits
  • Medical, dental, vision, and life insurance plans for employees
  • 401k
  • Relocation support may be provided for certain situations, based on business need.
  • Flexible vacation policy

About Hadrian

Hadrianadri?ja?n?s]; 24 January 76 – 10 July 138) was Roman emperor from 117 to 138. He was born in Italica, a Roman municipium founded by Italic settlers in Hispania Baetica and he came from a branch of the gens Aelia that originated in the Picenean town of Hadria, the Aeli Hadriani. His father was of senatorial rank and was a first cousin of Emperor Trajan. Hadrian married Trajan's grand-niece Vibia Sabina early in his career before Trajan became emperor and possibly at the behest of Trajan's wife Pompeia Plotina. Plotina and Trajan's close friend and adviser Lucius Licinius Sura were well disposed towards Hadrian. When Trajan died, his widow claimed that he had nominated Hadrian as emperor immediately before his death. Rome's military and Senate approved Hadrian's succession, but four leading senators were unlawfully put to death soon after. They had opposed Hadrian or seemed to threaten his succession, and the Senate held him responsible for their deaths and never forgave him. He earned further disapproval among the elite by abandoning Trajan's expansionist policies and territorial gains in Mesopotamia, Assyria, Armenia, and parts of Dacia. Hadrian preferred to invest in the development of stable, defensible borders and the unification of the empire's disparate peoples. He is known for building Hadrian's Wall, which marked the northern limit of Britannia.
