Job Description

Optasia is a fully enabled B2B2X financial technology platform covering scoring, financial decisioning, disbursement and collection. We are committed to enabling financial inclusion for all. We are changing the world our way.

Since company’s inception, over a decade ago, we have grown to become a global leader in the Fintech fields, constantly expanding and adding new solutions, offerings, and untapped monetization opportunities for all our partners and clients.

As member of the Systems Engineering team in Optasia, your primary objective is to guide the Hardware & Virtualization team in maintaining a stable, well-structured, and efficiently scaled infrastructure, ensuring that all server, storage, and VMware platforms operate smoothly and remain aligned with business and lifecycle requirements.

What you will do

• Lead the Hardware & Virtualization team to ensure operational excellence, capacity optimization, and service continuity.
• Oversee the full lifecycle of servers, storage systems, SAN/fiber switches, and VMware environments — from procurement to deployment.
• Lead SAN administration activities including zoning, multipathing, WWN management, and performance troubleshooting.
• Manage end-to-end deployment of new hardware: racking, cabling, zoning, configuration, and integration into production environments.
• Coordinate and execute hardware procurement activities, including ordering new equipment, validating BoMs, and working with vendors for quotations, delivery, and support.
• Define and enforce infrastructure configuration standards and documentation practices.
• Perform capacity planning for on-premise and third-party hosted environments, including sizing for upgrades and new deployments.
• Manage incident resolution, O&M activities, and escalation with vendors or support providers.
• Supervise firmware, Storage OS and ESXi upgrades, ensuring minimal downtime and rollback preparedness.
• Maintain accurate inventory management through tools such as Device42 and SSMC.
• Track End of Support and End of Life for hardware and coordinate timely replacements or migrations.
• Administer support contracts and ensure SLA compliance with vendors and service providers.
• Collaborate with cross-functional teams to deliver migration projects and infrastructure improvements.
• Provide leadership, mentoring, and technical guidance to team members.

• What you will bring
• 5+ years of experience in infrastructure engineering, with at least 2 years in a leadership or senior technical role.
• Strong hands-on knowledge of VMware virtualization technologies.
• Experience managing enterprise server and storage platforms, including configuration, maintenance, and lifecycle management.
• Practical experience with SAN environments, FC fabrics, zoning, and fiber switch administration.
• Strong capability in racking, cabling, configuring, and integrating servers, storage arrays, and SAN switches.
• Experience with procurement processes: reviewing hardware requirements, validating configurations, and coordinating vendor orders.
• Familiarity with monitoring and inventory tools such as SSMC and Device42.
• Proven ability to manage capacity planning, incident management, and O&M in complex environments.
• Proven ability to manage a small team.
• Solid understanding of firmware and hypervisor upgrade procedures.
• Experience handling hardware support contracts, EOS/EOL tracking, and vendor coordination.
• Excellent organizational, documentation, and communication skills.
