The Opportunity

Are you a network professional who enjoys digging into complex problems, strengthening network security, and taking ownership of the technology environments you support?

JMARK Business Solutions is looking for a Network Engineer II to join our team as a dedicated onsite IT resource for one of our banking clients. You will be a JMARK employee while working primarily onsite at the client's location, becoming a trusted technology resource for the bank while remaining fully connected to JMARK's larger team of engineers, technical resources, and leaders.

This role is designed for someone who has progressed beyond foundational networking and is ready to take greater ownership of network infrastructure, security, troubleshooting, and proactive technology management.

Because you'll be supporting a banking environment, reliability, security, documentation, communication, and attention to detail matter.

At JMARK, our philosophy is simple: People First. Technology Second.

We're looking for an engineer who understands that a stable and secure network isn't the end goal. The goal is helping the people and businesses relying on that network succeed.

What You'll Do

As a Network Engineer II, you'll provide advanced onsite and remote technical support while helping maintain the security, stability, performance, and reliability of the client's technology environment.

You'll work independently and alongside JMARK's Service, Engineering, Project, and Technical Assistance Center resources to:

• Troubleshoot and resolve advanced network, connectivity, infrastructure, and server issues.
• Respond to escalated technical issues from Level 1 resources.
• Diagnose issues onsite, remotely, and over the phone.
• Manage, maintain, troubleshoot, and support network infrastructure.
• Secure and manage network environments to protect productivity, mitigate threats, reduce risk, and improve stability.
• Administer and troubleshoot firewalls, switches, wireless networks, VPNs, and related network security technologies.
• Provide operational security support for the client's infrastructure.
• Monitor network health and proactively identify potential problems.
• Review network environments and service tickets to identify recurring or systemic issues.
• Resolve proactive issues when possible and engage Level 3 or specialized JMARK resources when necessary.
• Work with Project Managers and other technical resources on projects, implementations, and technology initiatives.
• Perform installations, upgrades, migrations, preventative maintenance, and infrastructure changes.
• Maintain a healthy service queue and ensure assigned issues continue moving toward resolution.
• Participate in JMARK's on-call rotation as assigned.

Network Engineering and Security

A significant part of this role is maintaining a reliable and secure network environment.

You should be comfortable working with technologies and concepts including:

• Firewalls, routers, switches, and wireless access points.
• VLANs and LAN switching.
• VTP and Spanning Tree Protocol.
• 802.x authentication.
• Routing protocols and route troubleshooting.
• VPN administration and troubleshooting.
• Secure administrative access to network devices.
• Network Intrusion Prevention Systems.
• Network monitoring and alerting technologies.
• Wireless network technologies.
• Physical cabling and network infrastructure.
• IP addressing and subnetting.
• CIDR and multicasting.
• IPv4 and IPv6.
• WAN technologies and connectivity.
• Endpoint and network security technologies.

You'll be expected to understand how these technologies work together and use that knowledge to troubleshoot problems, improve performance, and reduce risk.

Tools and Technologies

Depending on the environment and project, you may work with technologies and tools such as:

• Cisco networking technologies.
• Cisco ASA and VPN technologies.
• Cisco Call Manager and Call Manager Express.
• Cisco Unity.
• Cisco TelePresence.
• Cisco intrusion prevention technologies.
• Meraki networking technologies.
• Network monitoring platforms.
• SSH.
• Wireshark.
• LogRhythm.
• ConnectWise.
• Windows Server environments.
• Microsoft 365 and Microsoft technologies.

Experience with every technology listed isn't required. What matters is having a strong networking foundation and the ability to apply that knowledge across different platforms and environments.

More Than Keeping the Network Online

At the Network Engineer II level, we expect you to look beyond the immediate issue.

If the same problem keeps appearing, you'll ask why.

If you see a potential vulnerability, you'll raise it.

If an infrastructure change could improve reliability or security, you'll help evaluate it.

You'll be expected to:

• Identify systemic and recurring technology problems.
• Recommend sustainable solutions rather than repeatedly treating symptoms.
• Help reduce technology risk and improve network reliability.
• Use network monitoring tools to identify performance and availability issues.
• Maintain accurate network and technical documentation.
• Document troubleshooting steps, changes, configurations, and resolutions within ConnectWise.
• Review documentation from Level 1 resources and help improve its quality.
• Escalate appropriately when an issue requires Level 3 or specialized expertise.
• Follow established change-management and security practices.

Supporting a Banking Client

This isn't a traditional role where you'll support a client from a distance and move on to the next ticket.

You'll work primarily onsite with one of JMARK's banking clients, giving you the opportunity to develop a deep understanding of their environment, employees, business operations, and technology needs.

You'll become one of the client's trusted technology resources while having the support of JMARK's broader technical organization behind you.

You'll interact with everyone from end users to managers and executives, so you'll need to:

• Communicate technical issues in clear, understandable language.
• Recognize that most users want a solution, not a technical lecture.
• Provide courteous and professional service regardless of someone's technical ability or title.
• Set expectations and communicate progress throughout an issue.
• Take ownership and follow problems through to resolution.
• Build strong professional relationships with the people you support.
• Protect the confidentiality, integrity, and availability of the client's technology environment.
• Understand the importance of consistency, security, and attention to detail within a financial-services environment.

What We're Looking For

We're looking for someone who combines strong networking skills with great troubleshooting instincts and exceptional client service.

You'll likely thrive in this role if you:

• Enjoy solving complex networking problems.
• Understand networking beyond basic connectivity troubleshooting.
• Have hands-on experience configuring and troubleshooting firewalls, switches, wireless networks, and VPNs.
• Understand routing, switching, VLANs, subnetting, and network security.
• Can independently troubleshoot issues while recognizing when additional expertise is needed.
• Think proactively and look for potential problems before they become outages.
• Understand that security is part of every technology decision.
• Take documentation seriously.
• Manage priorities effectively and keep your work organized.
• Communicate confidently with both technical and nontechnical audiences.
• Stay composed when technical issues are urgent or business-critical.
• Take accountability for your work and follow through on commitments.
• Enjoy sharing knowledge and helping other technical team members grow.
• Are curious and continually want to expand your technical expertise.
