Network Security Engineer

Required Skills & Experience

• 8+ years’ experience in hands-on network and/or network security engineering roles.
• Strong practical experience with:
• Enterprise networking (routing, switching, segmentation)
• Network security technologies (firewalls, policy enforcement, access controls)
• Proven ability to design and implement secure, scalable network solutions.
• Strong understanding of:
• Zone-based security models
• Policy design and rulebase structure
• Network segmentation principles
• Experience working in project delivery environments, contributing directly to build and implementation activities.
• Comfortable working with existing environments, understanding constraints, and improving them pragmatically.
• Strong technical documentation skills, with the ability to clearly articulate designs and configurations.

Highly Desirable Skills

• Experience with major network and security vendors (e.g. Palo Alto, Cisco, Fortinet, Juniper, etc.).
• Exposure to cloud networking and security, particularly where it intersects with enterprise networks.
• Experience with automation or scripting (e.g. Ansible, Terraform, Python) to support repeatable builds or policy management.
• Experience using migration or assessment tools for network or firewall transformations.
• Relevant network, security, or platform certifications.
• Candidates should be able to join in 30 days or less

Qualifications

Role Overview-

 

We are seeking a Network & Security Engineer with strong hands-on experience in design, build, and delivery of enterprise network and security solutions. This role is part of a technical delivery team supporting multiple customer projects across network and security domains, starting with a major mining customer.

The role is engineering-led, with a strong emphasis on design, implementation, and transformation. The ideal candidate enjoys working close to the technology, translating design intent into working solutions, and operating across varied project contexts.

 

Key Responsibilities-

• Design, implement, and deliver network and security solutions across enterprise environments.
• Perform engineering-level design activities, including:
• High-level designs (HLDs)
• Detailed designs (LLDs)
• Configuration standards and build templates
• Design validation and technical assurance
• Assess existing network and security implementations, identifying inefficiencies, risks, and improvement opportunities.
• Engineer and optimise network security controls, including:
• Segmentation and zoning models
• Firewall and access control rulebases
• Policy structure, naming, and hierarchy
• Execute network and security migrations and transformations, such as:
• Legacy platform uplift or consolidation
• Policy re-design and rulebase clean-up
• L3/L4 designs evolving toward application-aware security models
• Work with enterprise-scale environments, potentially involving:
• Multiple sites or regions
• Large rulebases and complex network topologies
• Produce clear, high-quality engineering documentation.
• Collaborate closely with:
• Other network and security engineers
• Technical leads and solution designers
• Project managers and delivery teams
• Support multiple project engagements while maintaining consistency and engineering quality.
