Job Description

Within our Federal division, Arista supports critical missions across defense, intelligence, and civilian agencies. We are committed to helping federal customers modernize and secure their networks while ensuring compliance with government standards and cybersecurity frameworks.

Who You’ll Work With

Are you a top‑tier Technical Support Engineer with a passion for working on mission‑critical networks? At Arista, our Federal Technical Solutions Engineers are at the forefront of supporting U.S. government customers who depend on Arista products for secure and resilient networking.

As a Federal TSE, you’ll be part of a specialized support organization that partners closely with federal agencies, system integrators, and defense contractors. You’ll provide deep technical expertise, ensuring our solutions deliver uncompromising performance, reliability, and compliance.

You’ll work closely with product management, software/hardware engineering, and customer engineering teams to diagnose complex technical challenges. The team culture emphasizes collaboration, continuous learning, and a shared commitment to customer success.

What You’ll Do

The ideal candidate possesses the ability to troubleshoot complex and dynamic customer environments while balancing the communications needs of each case. A strong analytical mind is required, as is the ability to triage. As we are continually releasing new features and products, a high aptitude for both learning and teaching is required.

Our engineers work closely with other members of Customer Engineering as well as both Software and Hardware development—both in diagnosing problems as well as communicating them in multiple technical contexts. Thus, excellent written and verbal communication skills are a must, as is a collaborative approach.

Key Responsibilities

• Provide advanced technical support for federal customers via phone, email, and secure communication channels.
• Troubleshoot and resolve complex hardware, software, and network configuration issues in data center, campus, and routing deployments.

• Document customer interactions, recurring issues, and provide feedback to engineering for continuous product improvement.
• Assist in developing knowledge base content and best practices tailored to the federal networking community.

Qualifications

• Working knowledge of networking industry standards, products, and protocols.
• Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, Information Technology, or related field.
• 2–5 years of hands‑on experience in designing, deploying, configuring, and supporting network environments.
• Strong understanding of networking protocols and technologies: AAA/TACACS, ACL, ARP, BGP, DHCP, Ethernet, ICMP, IGMP, IPv4/IPv6, LACP, LLDP, MPLS, NAT, OSPF, PIM, QoS, RIP, SNMP, STP/RSTP/MST, VLAN, VRF, and other related technologies.
• Experience using troubleshooting tools such as tcpdump, Wireshark, and IXIA.
• Strong Linux command‑line and scripting familiarity (Python, shell, etc.).
• Excellent verbal and written communication skills, especially for high‑security or compliance‑driven environments.
• The customer base requires U.S. Citizenship, background checks, potential clearance processes, etc. Active security clearances are preferred (TS/SCI), but not mandatory.
• Experience supporting U.S. federal customers or integrators (DoD, IC, or Civilian) is preferred.
• Familiarity with FIPS, DISA STIGs, and other government compliance standards.
• Industry certifications (CCNP, JNCIP, Arista ACE, or similar) are a plus.
