Come join a growing financial technology company that’s leading the marketplace in both the marketing and servicing of credit cards! Continental Finance Company specializes in credit card options for those consumers with less than perfect credit. We are seeking a Senior Infrastructure Support Specialist II to join our Technology Team.
This role supports our infrastructure across two focus areas: networking and operating systems. This posting is for the Networking track: keeping our routers, switches, firewalls, wireless access points, and VPN connections secure and reliable, along with foundational AWS networking constructs (NACLs, security groups, and AWS-native firewall). A foundational understanding of AWS is expected; deeper AWS certification is a plus, not a requirement. This role also carries an on-call rotation, which occasionally includes basic OS-level troubleshooting — while systems administration is not the primary focus of this track, some working OS support ability is expected. This role is also a natural next step for team members growing up from our Infrastructure Support I position.
CFC offers a hybrid work schedule which includes three (3) core days in the office (Tuesday, Wednesday, and Thursday) and two (2) remote workdays (Monday and Friday)
This position participates in an on-call rotation.
ESSENTIAL FUNCTIONS:
- Install, configure, and maintain on-premises networking hardware, including routers, switches, firewalls, and wireless access points (e.g., Cisco Catalyst, Cisco Meraki, FortiGate, Palo Alto, and Ubiquiti).
- Configure and maintain site-to-site and client VPN connections, including SSL VPN and Zero Trust Network Access (ZTNA) for individual remote access.
- Design network and subnet layouts with an eye toward capacity planning and future growth.
- Maintain FTP/SFTP services and associated user accounts, including provisioning, permissions, and periodic access review.
- Support certificate management for network equipment (e.g., firewalls, VPN concentrators) in coordination with the OS Support track.
- Manage foundational AWS networking constructs — NACLs, security groups, and AWS-native firewall services — to enforce traffic control policies.
- Troubleshoot and resolve complex network connectivity, performance, and routing issues across on-premises and cloud environments.
- Monitor network health and performance using existing monitoring and alerting tooling, including SNMP-based device monitoring, escalating and resolving anomalies.
- Participate in an on-call rotation, responding to network outages and connectivity issues outside business hours — including basic OS-level troubleshooting in coordination with the OS Support track when needed.
- Maintain network documentation (topology diagrams, configuration records, runbooks) and identify opportunities to improve operational awareness and efficiency.
- Participate in audits and security reviews, providing required IT documentation and information.
- Support configuration management, change control, and documentation standards, and drive adoption of continuous improvements in accordance with the ITIL framework.
- Participate in network upgrades, migrations, and technology implementation projects.
- Perform regular and routine maintenance activities in accordance with compliance and regulatory guidelines.
- Perform other duties as assigned.
BASIC QUALIFICATIONS:
- Minimum of a high school diploma or GED; BA or BS degree preferred.
- Minimum of 5 years' experience working in the Information Technology industry.
- Hands-on experience configuring and maintaining routers, switches, firewalls, and wireless access points in a multi-vendor enterprise environment (e.g., Cisco Catalyst, Cisco Meraki, FortiGate, Palo Alto, Ubiquiti).
- Experience configuring and maintaining site-to-site and client VPN connections, including SSL VPN and Zero Trust Network Access (ZTNA) solutions.
- Experience with network and subnet design for capacity planning and scalable growth.
- Experience maintaining FTP/SFTP services and associated user accounts.
- Familiarity with certificate management as it applies to network equipment (e.g., firewall or VPN certificates) is a plus.
- Understanding of SNMP for network device monitoring.
- Working knowledge of foundational AWS networking — VPC, NACLs, security groups, and AWS-native firewall services.
- Solid understanding of TCP/IP, routing, subnetting, and structured network troubleshooting.
- Foundational understanding of AWS; AWS Certified Cloud Practitioner is a plus, not required.
- Willingness and ability to participate in an on-call rotation.
- Comfortable with basic OS-level troubleshooting (Windows/Linux) to support on-call escalations; deep systems administration expertise is not required for this track.
- Networking certifications (e.g., CompTIA Network+, Cisco CCNA) are a plus.
- Familiarity with IT governance and compliance frameworks such as PCI DSS is a plus.
- Excellent analytical and troubleshooting skills, with the ability to collaborate across teams.
- Ability to work well under deadlines and in a demanding environment.
- Familiarity with the principles and practice of configuration management and change control.
- The position requires minimal travel; occasional travel may include overnight stays depending on company needs.

Search System Administrator Jobs in DelawareSystem Administrator Jobs in Delaware: Frequently Asked Questions
Which companies sponsor visas for system administrators in Delaware?
Financial institutions with large Wilmington presences, including JPMorgan Chase, Bank of America, and Barclays, regularly sponsor system administrators through H-1B petitions. DuPont and Chemours also maintain active IT teams with sponsorship histories. State government contractors and healthcare organizations such as Nemours Children's Health round out the employer picture for internationally sponsored system administrator roles in Delaware.
Which visa types are most common for system administrator roles in Delaware?
The H-1B is the most frequently used visa for system administrator positions in Delaware, provided the role requires at least a bachelor's degree in a relevant field such as computer science or information systems. Canadian and Mexican nationals may qualify under the TN visa category. Candidates already holding L-1 visa status through an intracompany transfer are also well represented in Delaware's financial and chemical industry employers.
Which cities in Delaware have the most system administrator sponsorship jobs?
Wilmington accounts for the large majority of system administrator sponsorship activity in Delaware, driven by its concentration of banking and financial services firms. Newark, home to the University of Delaware and a growing technology cluster, is a secondary hub with both academic and private sector opportunities. Dover, as the state capital, offers openings within state government IT departments and associated contractors.
How to find system administrator visa sponsorship jobs in Delaware?
Migrate Mate filters job listings specifically by visa sponsorship availability, making it straightforward to identify system administrator roles in Delaware where employers are actively open to sponsoring international candidates. Using Migrate Mate's state and role filters narrows results to Delaware-based positions, helping you avoid applying to roles where sponsorship is unlikely and focusing your effort on employers with a documented history of sponsoring system administrators.
Are there any state-specific considerations for system administrators seeking sponsorship in Delaware?
Delaware's Department of Labor follows federal prevailing wage requirements for H-1B positions, so employers must document that compensation meets Department of Labor wage levels for system administrator roles in the Wilmington or Dover metropolitan areas. The University of Delaware serves as a notable pipeline, and its Office of International Students and Scholars supports OPT-to-H-1B transitions for graduates entering system administrator roles with Delaware-based employers.
What is the prevailing wage for sponsored system administrator jobs in Delaware?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
