Network Engineer IV

RESPONSIBILITIES:

Kforce has a client in Greenwood Village, CO that is seeking a senior-level Load Balancer Network Engineer (Level IV) to join our Data Center Architecture & Engineering team. This role is ideal for an engineer who thrives in complex, large-scale environments, brings deep hands-on expertise in BGP, IPv6, and load balancing, and has a strong foundation in automation and Python programming.

You will play a key role in designing and building next-generation data center platforms using multi-vendor spine-leaf network architectures, ensuring reliability, scalability, and performance across all network layers.

Key Responsibilities:

• Architect, design, and deploy data center network solutions with a focus on load balancing and automation
• Develop and implement Python-based automation for operational enhancements, testing, and configuration management
• Engineer multi-vendor spine-leaf topologies, supporting evolving platform and capacity needs
• Perform quality assurance testing, troubleshooting, and optimization of data center networking systems
• Collaborate with cross-functional architecture teams to define and evolve network standards and operational playbooks
• Maintain and enhance network monitoring, inventory, and reporting tools
• Lead the evaluation and integration of new technologies in lab environments before production rollout
• Serve as a subject matter expert (SME) on BGP, IPv6, load balancing, and full-stack networking (OSI layers 1-7)
• Partner with internal stakeholders and vendors to drive platform capabilities and technical innovation
  
  

REQUIREMENTS:

Must-Have Technical Expertise:

• BGP (Border Gateway Protocol) - Deep, Hands-On Knowledge
• Demonstrated experience configuring and managing EBGP and IBGP
• Ability to explain and implement loop prevention mechanisms and route reflectors
• Proven experience setting up BGP peering (provider and internal)
• Able to differentiate between writing base configurations from scratch vs. using templates
• Understands BGP architecture from an engineering and troubleshooting perspective-not just operational support
  
  

IPv6 & IPv4:

• Strong understanding of IPv6 architecture, addressing, and broadcast compared to IPv4
• Capable of designing and implementing dual-stack environments
  
  

Full-Stack Networking (OSI Model 1-7):

• Comprehensive understanding of all layers of the OSI model
• Can articulate how data flows and interacts across each layer in a real-world data center context
  
  

Protocols & Networking Concepts:

• Solid knowledge of UDP vs. TCP-when and why to use each
• Experience with VXLAN, EVPN, and Multicast Protocols
• Exposure to spine-leaf network topologies and data center routing architectures
  
  

Programming & Automation:

• Proficiency in Python for network automation, orchestration, and testing
• Experience with CI/CD integrations or automation frameworks is highly desirable
  
  

Evaluation Criteria:

• This team focuses on true engineering depth, not certifications or titles
  
  

Candidates must be able to:

• Clearly explain their hands-on experience under each role listed on their resume
• Demonstrate how they implemented and configured BGP, IPv6, or load balancing
• Discuss why architectural choices were made, not just what was done
• Confidently break down network design logic, failure scenarios, and optimization techniques
• Vague -managed,- -supported,- or -worked with- language will not meet the bar - we're looking for builders, designers, and problem solvers who understand their craft from the ground up
