Infrastructure Engineer, Principal (Los Angeles)

Hadrian - Manufacturing the FutureHadrian is building autonomous factories that help aerospace and defense companies manufacture rockets, satellites, jets, and ships up to 10x faster and up to 2x cheaper. By combining advanced software, robotics, and full-stack manufacturing, we are reinventing how America produces its most critical parts.We’re accelerating our mission with the launch of Factory 3 in Mesa, Arizona, a 290,000-square-foot facility creating 350 new jobs. We are expanding rapidly to support thousands of future hires, launching Hadrian Maritime to expand into naval production, and introducing a Factory-as-a-Service model that delivers complete systems instead of individual parts.Hadrian is backed by leading investors including T. Rowe Price, Lux Capital, Founders Fund, and Andreessen Horowitz, our fast-growing team is united around reindustrializing American manufacturing for the 21st century and beyond.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 DoDesign and implement cloud infrastructure on AWS using Terraform/OpenTofuBuild and manage Kubernetes clusters (EKS in cloud, K0s/K3s at the edge)Build CI/CD pipelines and GitOps workflows with GitHub Actions and ArgoCDDevelop reusable infrastructure patterns: Terraform modules, Helm charts, CUE schemasArchitect networking between sites, edge devices, and cloudImplement monitoring and observability with Prometheus/Grafana and DatadogSupport edge computing and IoT device deployments on factory floorsDrive build-vs-buy decisions and technology evaluationsEstablish engineering standards and best practicesRepresent infrastructure in cross-functional architecture reviewsMake architecture decisions under ambiguity and document them as ADRsIdentify systemic operational gaps and drive automation that eliminates recurring toilParticipate in on-call rotation and incident responseWrite clear documentation and runbooksWhat We’re Looking For10-15+ years in infrastructure or platform engineeringExpert-level infrastructure design across cloud, containers, and networkingCan go from architecture whiteboard to production implementation, and has done it repeatedlyDeep Terraform/IaC skills with module development and testing experienceProduction Kubernetes experience including troubleshooting, scaling, and multi-cluster patternsStrong security instincts: threat modeling, least privilege, compliance fundamentalsTrack record of building reusable patterns that other engineers adoptHistory of reducing complexity, not just adding capabilityStrong documentation and communication skillsComfortable mentoring teammates and sharing knowledgeWhat Will Set You ApartExperience defining infrastructure strategy and technical direction for an engineering orgTrack record of driving platform adoption across multiple teams without direct authorityBackground operating at scale: multi-site deployments, 20+ consuming teams, or similarly demanding environmentsHistory of mentoring senior engineers into technical leadersDeep experience with architecture trade-offs in hybrid cloud/edge environmentsDemonstrated ability to simplify systems and retire tools that no longer serve the orgCompensationFor 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 for Full-time EmployeesMedical, dental, vision, and life insurance plans for employees401kRelocation support may be provided for certain situations, based on business need.Flexible vacation policyEquityITAR RequirementsTo conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.
