Senior Infrastructure Developer (Python, VMware Cloud Foundation)

As part of our global Virtualization Engineering team, you’ll play a critical role in architecting, integrating, and automating our next-generation infrastructure based on VMware Cloud Foundation (VCF). We are embarking on a multi-year transformation, leveraging expert consultants to deliver a scalable, automated virtualization stack. You’ll work hands-on with VCF, Linux, Ansible, and our proprietary configuration management system to deliver robust solutions across both brownfield and greenfield environments.

Responsibilities:

• Design, implement, and automate configuration management for a large-scale, global VCF-based virtualization platform using Python and Ansible.
• Engineer and integrate APIs to provide infrastructure-on-demand and seamless interaction between on-prem and third-party tools.
• Lead lab-based testing, certification, and integration of new hardware and software components into existing infrastructure.
• Collaborate with internal stakeholders to gather requirements and architect scalable, resilient solutions.
• Ensure technical alignment with both vendor best practices and internal standards for reliability, automation, and security.
• Work independently to deliver on aggressive project timelines and resolve complex technical challenges.

Required Skills:

• Extensive experience automating infrastructure tasks (installation, configuration, management) using Python.
• Hands-on experience with automation frameworks (Ansible, Python) and Infrastructure as Code practices.
• Deep understanding of virtualization technologies, ideally VMWare Cloud Foundation (VCF) or vSphere.
• Strong technical fundamentals: TCP/IP, DNS, Linux, distributed systems.
• Experience integrating APIs and automating workflows across hybrid infrastructure stacks. Familiarity with software version control, CI/CD pipelines, and modern SDLC practices.

Desired Skills:

• Hands-on expertise with VMware’s suite (VCF, vSphere, vSAN) in both greenfield and brownfield rollout scenarios.
• Knowledge of software testing methodologies for infrastructure automation.
• Experience with other programming languages (e.g., Go, PowerShell, Bash).
• Understanding of containerization and cloud-native patterns.
• Experience working in high-pressure, global teams on multi-year strategic projects.

Personal Attributes:

• Self-motivated and able to operate independently with minimal oversight.
• Comfortable working under pressure and managing competing priorities.
• Excellent communication skills in a distributed, multicultural environment.
