Overview
Ontrac Solutions is seeking a Network Automation & Reliability Engineer to operate and automate hyperscale data center, backbone, and out-of-band (OOB) networks. This is a Python-first role: you will spend more of your week writing code that operates the network than typing on a CLI. You will build the tooling, telemetry pipelines, and self-healing automation that keep a global fleet of data centers and POP sites running, and you will carry the on-call pager for the systems you build.
We are looking for an engineer who is genuinely production-grade on both sides of the job — deep routing and switching fundamentals and real, sustained Python software work. Candidates who are strong on one side and thin on the other will not clear screening.
What your application must clearly show
We screen against the requirements below exactly as written — your resume should make these easy to find:
Python you actually wrote, described as software, not as a skills keyword. Name the project, what it did, roughly how large it was, and who used it. "Python (scripting)" in a skills list will not clear this bar. A GitHub, GitLab, or public repo link is strongly preferred — we look at code.
The specific Python network libraries you have used in production — for example Netmiko, NAPALM, Nornir, pyATS/Genie, Scrapli, ncclient, or a vendor SDK — and what you built with each.
BGP in production at scale. Name the policy work: local preference, MED, communities, import/export policy, route reflection, ECMP, or multihoming across carriers.
Hands-on with at least two of Arista EOS, Juniper Junos (QFX / SRX / PTX / MX), or Cisco IOS-XR / NX-OS — named by platform, not just by vendor.
Telemetry and observability you implemented: gNMI/gRPC, OpenConfig, streaming telemetry, flow telemetry, or SNMP-to-TSDB pipelines. Say what you subscribed to and what you did with the data.
Config-as-code: Jinja2 templating, NETCONF/YANG or REST-API-driven provisioning, golden configs, ZTP, and the Git/CI workflow you shipped changes through.
Your networking certifications, named, with dates and credential IDs or verification links — we verify certifications.
Whether you have carried production on-call , and at what scale (sites, devices, or POPs).
Shortly after you apply you will receive a short role-specific questionnaire — completing it promptly is the fastest way to move into screening.
Required Qualifications:
Python — primary requirement: Demonstrated, sustained Python development in a production network or infrastructure environment. You have written and maintained tooling that other engineers depended on: config generation and validation, API integrations, telemetry collectors, automated remediation, or test harnesses. You are comfortable with modules, packaging, testing, code review, and version control — not just single-file scripts.
Routing & switching depth: Production experience with BGP (policy, path selection, multihoming), plus IS-IS or OSPF, ECMP, and VXLAN/EVPN or MPLS overlays.
Multi-vendor hardware: Hands-on operations across at least two of Arista EOS, Juniper Junos (QFX/SRX/PTX/MX), or Cisco IOS-XR / NX-OS.
Automation frameworks: Ansible and Jinja2, plus NETCONF/YANG, RESTCONF, or vendor REST APIs for model-driven configuration management.
Telemetry & monitoring: gNMI/gRPC streaming telemetry, OpenConfig models, SNMP, flow telemetry, and dashboarding/alerting on top of them.
Linux: Comfortable operating on Linux hosts — networking stack, packet capture, systemd services, and shell scripting.
Version control and CI: Git-based workflows with peer review; experience shipping network changes through a pipeline (Jenkins, GitLab CI, or GitHub Actions).
Production on-call: Experience holding a 24x7 rotation for a live network, including incident command and root cause analysis.
Experience level: Roughly 2–5 years in a network production, network reliability, or network automation role. Exceptional early-career engineers with a strong Python portfolio and hyperscale or carrier exposure are encouraged to apply.
Location & work authorization: Must be located in the United States and authorized to work in the US.
Preferred Qualifications:
Out-of-band network experience — console server fleets (ZPE Nodegrid, OpenGear), RS-232 configuration management, or OOB build-out for new data center capacity.
Data center or POP build-out and turn-up: new product introduction (NPI) for switching platforms, port channelization and optics selection, cabling and rack density planning, or hardware qualification and stress testing.
MACsec, IPsec at scale, or zero-trust segmentation with 802.1X and NAC.
Optical or transport exposure — DWDM, Ciena, PON/OLT/ONU, or IXIA/Spirent test automation.
Building or contributing to a network source of truth (NetBox or in-house) aggregating BGP, link-state, and drain-state data.
Applying LLM or agentic tooling to on-call workflows — automated triage, runbook execution, or incident summarization.
A master's degree in Network Engineering, Telecommunications, or Computer Science.
Design, write, and maintain Python tooling that provisions, validates, and audits network devices across the global fleet.
Build model-driven provisioning libraries using Jinja2 templating with NETCONF/YANG or REST APIs to codify golden configurations and eliminate configuration drift.
Develop automated remediation for recurring failure classes — route flaps, hardware faults, optical degradation — triggered by syslog and telemetry.
Reduce operational toil: identify manual runbook steps that recur, and replace them with tested, reviewed code.
Key Responsibilities — Backbone, Data Center & Out-of-Band Operations:
Operate and scale data center fabrics, backbone links, and out-of-band management networks across a global footprint of data centers and POP sites.
Design and tune BGP policy — local preference, MED, communities, import/export policy, default-route propagation — to control path selection and eliminate single-carrier points of failure.
Support capacity expansion and site turn-ups: high-level design, port channelization, optics and cabling standards, and hardware qualification.
Execute zero-downtime change management in production, including hitless migrations and staged rollbacks.
