About Telnyx
Telnyx is an industry leader thats not just imagining the future of global connectivitywere building it. From architecting and amplifying the reach of a private global multi-cloud IP network to bringing hyperlocal edge technology right to your fingertips through intuitive APIs were shaping a new era of seamless interconnection between people devices and applications.
Were driven by a desire to transform and modernize whats antiquated automate the manual and solve real-world problems through innovative connectivity solutions. As a testament to our success were proud to stand as a financially stable and profitable company. Our robust profitability allows us not only to invest in pioneering technologies but also to foster an environment of continuous learning and growth for our team.
Our collective vision is a world where borderless connectivity fuels limitless innovation. By joining us you can be part of laying the foundations for this interconnected future. Were currently seeking passionate individuals who are excited about the opportunity to contribute to an industry-shaping company while growing their own skills and careers.
Were hiring a Network Engineer to join the Core Network Squad and own the production side of our global IP backbone. Youll take pre-prod handoffs from the AI Networking Squad turn new PoPs into live production sites and run the day-to-day of our backbone BGP IS-IS/OSPF MPLS peering transit and capacity. This is a hands-on engineering role on the inside of one of the more interesting global SP networks out there.
This is also an AI-native role. The AI Networking Squad is driving an aggressive automation roadmap and we expect every engineer to push it forward building tooling agents and workflows that take toil out of the network. Surface-level ChatGPT usage is not what we mean. We want engineers who are already shipping AI-built tools today.
What Youll Do
Primary Core network production & day-to-day (70%)
- Take pre-prod handoffs from the AI Networking Squad and bring new PoPs into production peering up route policy validation and cutover
- Own and operate the backbone: BGP (eBGP/iBGP communities route reflection traffic engineering) IS-IS or OSPF MPLS Segment Routing and EVPN where applicable
- Manage transit and peering Tier 1 relationships IX sessions prefix filtering RPKI route optimization
- Run capacity expansions new ports additional transit/transport circuits link upgrades optics swaps
- Troubleshoot production issues packet captures route analysis transport diagnostics and drive post-incident fixes
- Partner with the AI Networking Squad on automation: contribute to config generation validation pipelines network state checks and agentic workflows
- Support architecture scaling and integration initiatives across the backbone
- Help roll out new services and features alongside Core Network and product engineering teams
- Contribute to improvement work: protocol tuning observability automation coverage hardening
What Were Looking For
Must-Have
- 35 years of hands-on network engineering experience in a service provider carrier CDN hyperscaler or large-scale SP-style enterprise backbone
- Deep BGP eBGP and iBGP communities local-pref / MED route reflection traffic engineering dampening RPKI; comfortable designing and debugging policy at scale
- IGP fluency IS-IS or OSPF including multi-area design and convergence behavior
- MPLS and Segment Routing LDP RSVP-TE SR-MPLS / SRv6 awareness; familiarity with L3VPNs and EVPN/VXLAN
- Hands-on CLI on at least one of Juniper (Junos) Cisco (IOS-XR / NX-OS) Arista (EOS) Nokia (SR OS) or equivalent including config troubleshooting and upgrades on production gear
- Transit peering and IX experience how to bring up sessions structure policy and tune the routing table for performance and cost
- Optics and transport knowledge of grey/coloured optics DWDM basics transport circuits and how the physical layer feeds the routing layer
- Solid Linux fundamentals and a scripting language (Python preferred) youre comfortable on the box not just on the CLI
- AI-first mindset (required) demonstrated experience building workflows automations or tools with AI (prompt engineering AI-assisted coding agentic frameworks). Concrete artifacts beat claims. AI adoption and tool-building is a key component of long-term performance evaluation in this role
- Strong written communication clear runbooks RFC-style proposals incident write-ups and async updates
- Network automation experience Ansible NAPALM Nornir Netbox or similar
- Hands-on with infrastructure-as-code for network (YANG/NETCONF gNMI Terraform providers for network gear)
- Network validation and turn-up tooling (batfish suzieq custom validators)
- Out-of-band / console infrastructure (serial console servers OpenGear etc.)
- Experience with observability stacks for networks streaming telemetry Prometheus/Grafana flow analytics
- CCIE / JNCIE / equivalent senior cert or evidence of equivalent depth without the cert
- Production deployments land cleanly pre-prod handoffs become live PoPs without rework
- The backbone runs hot but stable your changes dont cause incidents and your incident write-ups make the network better
- Peering and transit policy is tight measurable and improving cost down performance up
- Youre shipping automation that the rest of the team adopts not just running CLI
- Anyone on the squad can pick up your work because your docs configs and PRs explain themselves
