Top Tech Jobs & Startup Jobs

Provide network engineering and support for datacenter and enterprise environments, including network design, architecture, virtualization, LAN/MAN/CAN infrastructure, packet capture, routing/switching, stateful firewalls, L3/L4 access controls, Cisco device installation/configuration, and ticketing system operations.

Provide customer support for HPC software: integrate, install, configure, upgrade, compile, and support COTS/GOTS across UNIX/Linux/Windows environments. Troubleshoot systems, work with HPC schedulers/resource managers, CM tools, and use scripting and languages (Shell, Python, C/C++, Java). Requires active TS/SCI with polygraph.

Administer, maintain, and support the PaaS component of a secure, multi-tenant Kubernetes-based compute environment. Integrate, install, configure, upgrade, and sustain COTS/GOTS software on Linux. Ensure cluster reliability, scalability, security compliance, and performance; troubleshoot workloads; automate with IaC/Ansible, Helm, and scripting; monitor with Prometheus/Grafana; and manage source control with Git.

Provide Tier 4 HPC support for federal sites, performing advanced configuration, tuning, testing, and troubleshooting of high-performance file systems (XFS, GPFS, Lustre), HPC farm systems and applications (Nagios, xcat, compilers), distributed schedulers (RES, LSF, SLURM), MPP systems, and RedHat/SUSE OS. Support federal customers requiring TS/SCI with agency polygraph.

Administer, maintain, and support a Linux-based PaaS Kubernetes environment: integrate and deploy COTS/GOTS software, manage cluster reliability and security, troubleshoot workloads, automate with IaC (Ansible), write Helm charts, script (Bash/Python), and monitor using Prometheus/Grafana.

Design, develop, test, deploy, and maintain complex software systems and HPC metrics/monitoring solutions. Implement DevOps practices (CI/CD, containers, IaC), build data collection/logging pipelines, develop algorithms, and lead software teams. Work requires Unix/Linux tooling, Rust and Python development, message brokers like Kafka, Splunk integration, and an active TS/SCI clearance with polygraph.

Design, architect, and support datacenter and enterprise LAN/MAN/CAN networks with strong emphasis on security. Responsibilities include packet capture, TCP/IP, routing/switching, stateful firewalls, L3/L4 access controls, datacenter virtualization, Cisco device installation/configuration, IPSEC VPNs, on-call support, and ticketing system usage.

Designs, implements, maintains, and optimizes LAN/CAN/WAN and telecom infrastructures. Performs engineering analysis, device configuration (Cisco/Arista/Juniper), VPN/IPSec/GRE/VoIP setups, network performance monitoring, accreditation support, and mentors junior engineers for federal mission environments.

The System Engineer will perform systems engineering activities throughout the lifecycle, develop documentation, and analyze technical alternatives, collaborating with teams and customers.

The System Administrator II supports, troubleshoots, and maintains IT systems, managing both UNIX and Windows operating systems, providing Tier I and II support, and ensuring system optimization and compliance.
