In this role, you will be responsible for maintaining and supporting existing on-premises infrastructure while partnering with IT and cross-functional teams to develop and execute a migration roadmap to GCP. You will play a critical role in ensuring operational stability, resilient system design, and engineering excellence for business-critical research workloads.

The successful candidate will bring deep expertise in traditional on-premises IT infrastructure, including physical and virtual servers, storage and file systems, Microsoft Active Directory, DNS, and related infrastructure services. The ideal candidate will also have strong experience with GCP cloud infrastructure, cloud IAM, networking, and infrastructure automation.

While this role will initially focus heavily on on-premises infrastructure, it will also help establish the systems, processes, standards, and automation practices needed to support cloud adoption and long-term infrastructure modernization.

Position Responsibilities:

● Maintain and support on-premises infrastructure, including HPC clusters, storage and file systems, physical and virtual servers, Active Directory, backups, and related infrastructure services.

● Drive efficient and well-planned migration efforts while minimizing disruption to R&D and scientific operations.

● Collaborate with Software Engineering, Data Science, ML Platform, and other teams to align on GCP infrastructure best practices.

● Promote scalable, secure, and standardized cloud infrastructure practices across teams.

● Work with technology partners, including Google Enterprise Network, Google Professional Services, sponsored research partners, and Contract Research Organizations, to support business and research needs.

● Develop and maintain clear architecture diagrams, infrastructure standards, operational runbooks, and support documentation.

● Identify opportunities to improve automation, infrastructure consistency, reliability, and operational efficiency.

Position Requirements:

● Bachelor’s degree in Computer Science, Information Systems, a related field, or equivalent practical experience.

● 5+ years of experience in on-premises infrastructure engineering, systems administration, or a related role.

● 5+ years of experience managing cloud infrastructure, preferably in GCP.

● Strong experience with enterprise infrastructure platforms, including virtualization, storage, backup, and data center operations.

● Expertise in Active Directory, Entra ID, Group Policy, DNS, DHCP, and hybrid identity management.

● Strong hands-on experience with Windows Server and Linux environments.

● Expertise in Google Cloud Platform, including Compute Engine, Cloud Storage, IAM, VPC, and hybrid connectivity.

● Experience with Google Kubernetes Engine (GKE), including cluster administration, workload management, and networking policies.

● Proficiency with infrastructure-as-code and automation tools such as Terraform, Ansible, or equivalent.

● Strong scripting experience with Python, Bash, or similar languages.

● Solid understanding of core networking concepts, including TCP/IP, DNS, DHCP, firewalls, routing, and troubleshooting utilities.

● Experience documenting architecture standards, recovery procedures, and operational runbooks.

● Familiarity with cybersecurity frameworks such as NIST CSF/CIS18, SOC 2, and ISO 27001.

● Ability to partner effectively with Information Security on hardening, compliance, vulnerability management, and incident response.

● Strong customer-service mindset and enthusiasm for supporting scientific software developers, data scientists, and R&D teams.

● Self-motivated, proactive, and able to work independently with minimal supervision. Comfortable working in ambiguous, fast-paced, and rapidly evolving R&D environments.

● Ability to communicate complex technical concepts clearly to both technical and non-technical audiences.

● Must be willing to work onsite at least four days per week.

Nice to Have:

● Certifications such as Google Cloud Professional Cloud Architect, Certified Kubernetes Administrator (CKA), or equivalent.

● Experience administering source code repositories such as Git, GitLab, or GitHub.

● Experience with cluster file systems such as Ceph, Lustre, or similar technologies.

● Experience supporting research, biotech, life sciences, or scientific computing environments.
