Network and Systems Engineer en P\S\L Group Mexico

The Network & Systems Engineer is a multifaceted role combining network architecture with systems engineering. This individual will design, implement, optimize, and maintain network and cloud-based systems infrastructure. The role emphasizes advanced cloud networking (especially AWS), automation, and performance, while flexibility is offered in areas like infrastructure as code and firewall specialization.

Network Responsibilities

• Design and implement plans to ensure network capacity meets current and future requirements.

• Implement robust security measures across network systems.

• Develop and deploy methodologies for testing and monitoring network performance.

• Stay current on emerging networking technologies to improve cost-effectiveness and flexibility.

• Manage and optimize security solutions including firewalls and WAFs (e.g., Fortinet, AWS WAF, Cloudflare).

• Administer network equipment and hardware, including Meraki switches and access points.

• Troubleshoot networking issues across VPCs, load balancers, and hybrid environments.

• Document network architecture, configurations, and processes.

Systems Responsibilities

• Design, deploy, and maintain serverless architectures using AWS services like Lambda, ECS, and S3.

• Manage EC2 instances, storage solutions, and IAM permissions.

• Contribute to automation efforts; experience with infrastructure as code (e.g., CloudFormation, Terraform) is an asset.

• Support high availability, scalability, and disaster recovery strategies.

• Maintain secure infrastructure practices (e.g., backups, logging, governance).

• Collaborate with DevOps teams to align infrastructure with CI/CD workflows.

General Responsibilities

• Collaborate with cross-functional teams to implement network and systems changes.

• Offer technical guidance on infrastructure improvements.

• Evaluate tools and solutions for network and systems enhancements.

• Support junior team members through mentoring and shared troubleshooting practices.

• Participate in on-call rotations and planned off-hour maintenance when needed.

Education and Experience

• Degree or diploma in computer science, engineering, or a related field.

• Minimum 5+ years in network engineering and systems architecture.

• Experience in cloud environments (AWS required; Azure and GCP are assets).

Technical Expertise

• Advanced knowledge of AWS networking and services (e.g., EC2, ECS, VPC, Load Balancers, CloudFront, Lambda).

• Strong grasp of network protocols and design (e.g., BGP/eBGP, VPNs, DNS).

• Experience with Fortinet; familiarity with Palo Alto firewalls is a plus.

• Familiarity with infrastructure automation; experience with infrastructure as code (e.g., Terraform, CloudFormation) is an asset, not required.

• Experience with serverless environments and containerized applications.

• Exposure to hybrid infrastructure environments including Meraki hardware is a plus.

Certifications

• AWS Advanced Networking Speciality is a plus.

• CCNP, CCIE, or similar networking certifications are a plus.

• Palo Alto (PCCSE/PCNSE) and Fortinet (NSE 4+) certifications are considered assets.

• Certifications in IaC tools or scripting (Terraform, Python, etc.) are a plus but not required.

Soft Skills

• Strong problem-solving and analytical abilities.

• Excellent verbal and written communication in English.

• Able to work collaboratively across technical and non-technical teams.

• Self-driven, organized, and comfortable managing multiple priorities.
