Network Engineer

TekWissen LLC; Huntsville (AL); On-site; USD 95,000 - 125,000; Full time

Job summary

Accenture is seeking a Network Engineer for a 12-month onsite assignment in Huntsville, AL. You will support networks inside hardware validation labs worldwide, focusing on datacenter fabrics, timing, optical and provisioning systems from first bring-up to production handoff.

The role emphasizes L2/L3 lab fabric design, BGP, EVPN/VXLAN overlays, IPv6, timing (PTP), and multi-vendor operations with Arista, Cisco, Juniper, and SONiC.

Qualifications

• L2/L3 at depth: VLANs, loop prevention, LAG, IPv4/IPv6 addressing, SLAAC and router advertisements, DHCP relay and helpers, PXE boot flows end to end.
• BGP: eBGP peering design, prefix policy, uplink preference tuning, per-rack or per-site route origination toward the border and aggregation layer.
• Datacenter fabrics: leaf/spine role design, EVPN/VXLAN overlays, migrating racks from L2 bridged to L3 routed boundaries.
• IPv6 operations: first-hop security (RA guard, address locking), DHCPv6 relay and MAC-stable allocation behavior including client identifier pitfalls, /64 per rack scale planning and fabric design.
• Precision timing: PTP (IEEE 1588) design and troubleshooting, grandmaster placement, boundary and transparent clock concepts, sync quality monitoring against microsecond budgets.
• Fabrics for AI/HPC: PFC and lossless Ethernet tuning, link training, SerDes and optics basics (current generation high speed optics), awareness of how skew and tail latency hit collective communication.
• Optical and physical plant: fiber types and connectors, optical circuit switching concepts, commercial traffic generators, cable validation, fiber characterization from hardware timestamps.
• Access security: port ACLs, 802.1X/MAB flows, RADIUS, quarantine and remediation VLANs, device onboarding and registration.
• Multi-vendor fluency: deep on at least one datacenter NOS (Arista, Cisco, Juniper, SONiC) with demonstrated ability to pick up others, including API driven operation with rollback.
• Troubleshooting under pressure: packet level debugging, hardware timestamp analysis, method of procedure authorship, maintenance windows, rollback planning.
• Python for network automation: device APIs, text templating, input validation, operator CLI tooling.
• Templating: Jinja2 template design (reuse across sites and roles, safe defaults, per-port rendering from inventory).
• Config as code: distributed revision control fluency (branch, review, land, revert), config review culture, CI gates on generated config (diff review, automated land criteria).
• Intent modeling: declarative source of truth thinking where inventory plus intent renders device config, and generated config is never hand edited.
• Linux networking: interfaces, routing tables, namespaces, capture tooling, service management, cookbook style config management (chef).
• Data hygiene: inventory accuracy (roles, port maps, serial to port bindings), drift detection, reconciliation loops.

Responsibilities

• Provide L2/L3 lab network design and operation across global hardware validation labs.
• Design datacenter fabrics (leaf/spine) with EVPN/VXLAN overlays; migrate L2 to L3 boundaries.
• Manage precision timing (PTP) and provisioning to support AI/ HPC workloads.
• Ensure security and access controls, and implement multi-vendor, API-driven operations.
• Develop automation in Python/Jinja2 for declarative config pipelines and IaC practices.
• Troubleshoot complex network issues under pressure and document procedures for playbooks.

Job Type: Temporary Assignment

Work Type: Onsite

Role snapshot

You support the networks inside hardware validation labs around the world: the datacenter fabrics, timing, optical, and provisioning systems that let accelerator teams validate new platforms from first bring-up through production handoff. L2/L3 lab fabric design, precision timing as a service, intent based provisioning and automation, optical plus test infrastructure, lab operations and reliability, and cost takeout through decommissioning.

Required: network engineering

• L2/L3 at depth: VLANs, loop prevention, LAG, IPv4/IPv6 addressing, SLAAC and router advertisements, DHCP relay and helpers, PXE boot flows end to end.


• BGP: eBGP peering design, prefix policy, uplink preference tuning, per-rack or per-site route origination toward the border and aggregation layer.


• Datacenter fabrics: leaf/spine role design, EVPN/VXLAN overlays, migrating racks from L2 bridged to L3 routed boundaries.


• IPv6 operations: first-hop security (RA guard, address locking), DHCPv6 relay and MAC-stable allocation behavior including client identifier pitfalls, /64 per rack scale planning and fabric design.

Required: operations and delivery

• Lab or datacenter operations: oncall rotations, incident response, break/fix prioritization, vendor RMAs, multi-site coordination.


• Change discipline: method of procedure authorship and peer review, blast radius control, pilot then scale.


• Cost awareness: circuit inventories, carrier coordination for turn-down, tracking recurring spend to zero with chargeback confirmation.


• Cross-functional delivery: shared ownership with platform teams (provisioning, observability), hardware bring-up teams, and lab customers, including consultative support outside the plan of record.

Preferred

• AI/HPC cluster networking: scale-up versus scale-out fabric design, RDMA capable fabrics, collective sensitivity to timing.


• Large fiber plant or optical switching operations.


• IPv6-first or IPv6-only environments at scale.


• Observability: time series metrics, topology visualization, low-noise alert design.


• Vendor evaluation: switch selection criteria, optics compatibility testing.

What predicts success here

This team works through internal platforms that all have direct industry analogues. We hire for the transferable skill; ramp covers the internal name. Git-backed hierarchical config management plus Jinja (Ansible/Salt/Puppet/Chef experience transfers), policy driven intent automation (declarative config pipelines transfer), graph modeled network state with diff-before-push (topology as data transfers), NetBox class inventory and asset sources of truth, in-house orchestration and topology visualization (any NMS you have operated or extended transfers), and Git class revision control with daily diff review.

Success in the first half looks like

A rack boundary migrated to routed operation with a clean demo, one provisioning flow that runs from intent with no manual CLI, timing service extended to a new cluster with monitoring attached, and every unplanned support ask tracked and categorized instead of lost in chat.
