System Administrator / DevOps

R&D

Tel Aviv-Yafo, Tel Aviv District, IL Full-time

Description

SuperCom (NASDAQ: SPCB) is a trusted name in advanced tracking, identification, and security solutions since 1988. We deliver multi-disciplinary solutions that combine hardware, software, communications, and cloud-based platforms in the fields of secure identity, public safety, and smart monitoring.
We are looking for an enthusiastic, collaborative, and highly motivated hands-on System Administrator with a DevOps mindset to join our infrastructure team and help build and maintain our customer-facing production environments, keeping them secure, monitored, and highly available.
This is not only a maintenance role. Together with the team you will stand up complete cloud and on-prem environments, configure network security, automate recurring operational work, and document it so the rest of the team can repeat it. We are looking for someone who takes ownership, wants to understand the full picture, is naturally curious and self-learning, and works independently and methodically, driving production issues to root cause rather than to a workaround.
Job description:

As part of the infrastructure team, build new customer environments from scratch and maintain them ongoing, in cloud (AWS / Azure) and on-prem: compute, networking, storage, load balancers, DNS, certificates, Active Directory, and application deployment
Own network security on Fortinet (FortiGate): security policies, NAT, routing, IPSec/SSL VPN tunnels, HA pairs, and FortiAuthenticator / FortiClient EMS
Manage Active Directory across all customer environments: user accounts, security groups, group policies, permissions, and access control
Maintain on-prem infrastructure: VMware / ESXi virtualization, backup and recovery, storage systems, and ongoing server maintenance, including Windows Server updates, patching, reboots, and health checks
Build and maintain monitoring and alerting, and handle the full lifecycle of SSL/TLS certificates across environments
Configure and maintain load balancers (HAProxy, Azure Application Gateway, Fortinet), DNS records, and firewall rules for proper access control and security compliance
Automate recurring operational work using scripting (PowerShell / Bash) and CI/CD tooling (Git, Jenkins)
Take part in periodic DR and site failover testing together with the team
Standardize IT processes, improve operational consistency across regions, and document recurring tasks and create runbooks so processes are repeatable and auditable

Requirements

6+ years of experience in system administration, IT operations, or infrastructure engineering
Hands-on experience with Windows Server: RDP, IIS, Windows services, event logs, patching, and general server maintenance
Hands-on experience with AWS or Azure, including provisioning and networking (VNet/VPC, subnets, NSGs/security groups, gateways)
Solid networking fundamentals: TCP/IP, DNS, VLANs, routing, and VPN, with the ability to troubleshoot connectivity issues methodically
Scripting ability (PowerShell or equivalent) for automating operational tasks
Experience with monitoring systems and a strong, structured troubleshooting mindset
Strong working-level English, spoken and written, with the ability to communicate, document, and collaborate with international teams
Hands-on Fortinet FortiGate experience: security policies, NAT, routing, site-to-site / remote-access VPN, HA pairs, and FortiAuthenticator / FortiClient EMS - an advantage
Proven experience building environments from scratch, not only operating existing ones - an advantage
Virtualization (VMware / ESXi), backup and recovery (such as Veeam), and storage systems (SAN/NAS, LUN provisioning, iSCSI/Fibre Channel, RAID, capacity planning) - an advantage
DR and high-availability architecture: SQL Server Always On Availability Groups, Windows failover clustering, backup and recovery, including hands-on failover testing - an advantage
