Senior Network Engineer

We are seeking an experienced Senior Network Engineer to support a major enterprise network transformation initiative for a large government organization. In this role, you will lead complex network migrations involving Juniper MX960 routers and the transition from MC-LAG to EVPN/VXLAN architectures. You will combine hands-on implementation with network architecture design to deliver scalable, resilient, and high-performing infrastructure. Working closely with network engineering teams, you will oversee critical production cutovers while minimizing service disruptions. This remote, 12-month contract offers the opportunity to contribute to a large-scale transformation project, with potential for extension. Quarterly travel to Philadelphia and occasional after-hours support are expected.

• As a Senior Network Engineer, you will lead enterprise network migration activities, validate advanced routing architectures, and ensure reliable implementation across production environments.

  • Plan, prioritize, and execute enterprise-scale migrations involving Juniper MX960 routers.

  • Design, validate, and implement EVPN/VXLAN architectures with multiple overlays to support scalability, performance, and redundancy.

  • Collaborate with network engineering teams to ensure seamless integration and minimize disruption during migrations.

  • Configure, test, deploy, and troubleshoot Junos OS across Juniper MX and EX platforms in production environments.

  • Lead the transition from MC-LAG to EVPN, providing technical guidance on architecture, validation, testing, and troubleshooting.

  • Develop and maintain detailed documentation covering network designs, migration plans, cutover strategies, and post-migration procedures.

  • Serve as a subject matter expert in Juniper routing technologies, EVPN/VXLAN fabrics, and advanced routing protocols.

  • Support after-hours cutovers and provide escalation assistance during critical network events.

The ideal candidate will bring extensive enterprise networking experience, strong expertise in Juniper technologies, and a proven ability to manage complex migrations in large-scale production environments.

• At least 7 years of experience as a Network Engineer in enterprise or large data center environments.

• At least 5 years of hands-on experience with Juniper MX and EX platforms.

• Strong knowledge of core routing protocols, particularly BGP and OSPF.

• Proficiency in configuring and troubleshooting Junos OS in production environments.

• Demonstrated experience with large-scale router replacement and network migration projects.

• Familiarity with EVPN architecture, deployment, and operational practices.

• Strong analytical, troubleshooting, and problem-solving skills.

• Excellent communication and collaboration skills for working with cross-functional engineering teams.

• Juniper certifications such as JNCIP, JNCIE, or equivalent.

• Experience with network automation and scripting tools, including Python and Ansible.

• Knowledge of security best practices for routing and switching.

• Familiarity with enterprise change management and technical documentation processes.
