Information Security Specialist Capability Delivery

PLDT MGO Building, Makati | Full Onsite | Dayshift

Are you someone who's spent years keeping systems running, secure, and properly configured, not just requesting access to them

At SMART, you'll join our Cyber Security team as a hands-on specialist, working across infrastructure, networks, and identity systems to design, implement, and continuously strengthen our security posture. You'll own real infrastructure and real controls, not tickets, this is a role for builders and administrators.

We know strong infrastructure and security talent comes from many paths, enterprise IT, network engineering, systems administration, and more. We welcome applicants from all backgrounds and career journeys who bring the hands-on foundation this role calls for.

What You'll Be Doing

1. Administer and secure enterprise infrastructure, servers, systems, and network environments, as the backbone of our security posture
2. Implement and operate security controls across identity, network, and endpoint layers, not just monitor or request them
3. Own day-to-day administration of Active Directory and Microsoft Entra ID
4. Apply network security fundamentals (TCP/IP, DNS, DHCP, VPN, firewalls, segmentation) to block unauthorized access and threats
5. Evaluate and redesign security controls end-to-end, thinking architecturally about how systems, identity, and network layers work together
6. Lead the rollout and operationalization of new security platforms and capabilities
7. Partner with infrastructure, network, and security teams to deliver end-to-end security solutions

What We're Looking For (the non-negotiables)

1. Strong hands-on experience administering security infrastructure (servers, systems, platforms) in a live production or enterprise environment — not primarily personal projects, certifications, or lab environments
2. Solid understanding of network security fundamentals (TCP/IP, DNS, DHCP, VPN, firewalls, segmentation)
3. Proven experience administering Active Directory or Microsoft Entra ID
4. Ability to understand how these technologies work together from an architectural perspective
5. Real, hands-on experience implementing and operating security controls — not just monitoring or requesting them

Note: This role is not focused on access provisioning, access reviews, or audit support. If your background is mainly in those areas, this may not be the right fit, but we may have other opportunities where your experience is a stronger match.

Trainable On the Job (don't worry if you don't have these yet)

You don't need to already know every tool we use. If you have a solid foundation and understand the principles of Zero Trust or SASE, we'll train you on:

1. Zscaler (ZIA/ZPA)
2. VMware vSphere
3. Endpoint Detection & Response (SentinelOne, CrowdStrike)
4. PAM platforms (Delinea, CyberArk)
5. WAF and other security platforms in our stack

You'll Thrive Here If You've Worked In

1. Infrastructure or Systems Administration
2. Enterprise IT Operations
3. Network or Security Engineering
4. IT environments where you owned servers, networks, or identity platforms end-to-end in a live production setting

Why This Role Is Different

This is a hands-on Individual Contributor role. You'll collaborate across teams, but the ownership of implementation and delivery stays with you.

We're not looking for someone who checks every box on paper. We're looking for someone with the right foundation, the right mindset, and the drive to grow into a true security capability owner.

Why Join SMART

1. Long-term career stability compared to project-based or consulting roles
2. Cybersecurity certifications and upskilling support
3. Exposure to industry events and conferences (e.g., RootCon)
4. A clear growth path within Cyber Security Capability Delivery

If you're someone who builds, secures, and owns infrastructure rather than just processing requests, we'd love to hear from you.
