About The Position

Telnyx operates a global telecom platform running on bare metal infrastructure across data centers worldwide. As a Staff Platform Engineer, you will own the shared platform layer that every engineering team builds on — from the Kubernetes clusters and service mesh that run our Elixir, Go, and Python services, to the CI/CD pipelines, observability stack, and internal tooling that keep us shipping reliably.

This is a high-leverage role. You won't just build infrastructure — you'll define what "platform" means at Telnyx and set the technical direction for how we operate at scale.

Requirements

• 7+ years in platform engineering, infrastructure, or SRE roles
• Deep expertise with Kubernetes — cluster lifecycle, operator development, multi-cluster management
• Strong experience with IaC (Terraform/Pulumi) in production
• Experience operating bare metal infrastructure — provisioning, PXE booting, switch config, data center networking
• Proficiency in at least two of: Elixir/BEAM, Go, Python
• Track record of shipping developer platforms adopted by 10+ engineers
• CI/CD at scale (GitHub Actions, Buildkite, or similar)
• Strong communication — RFCs, architecture decisions, stakeholder alignment

Nice To Haves

• BEAM clustering / Erlang/OTP in production
• Telecom or CPaaS experience (SIP, SS7, VoIP)
• Bare metal platforms (not just managed cloud)
• Open-source infrastructure contributions
• eBPF, Cilium, or advanced K8s networking
• Hardware security (TPM, secure boot)

Responsibilities

• Design, build, and operate Telnyx's core platform infrastructure — Kubernetes clusters, service mesh, CI/CD systems, and observability stack (Prometheus, Grafana, Loki)
• Own the Elixir/BEAM runtime platform — BEAM VM tuning, clustering, deployment patterns, and tooling for product teams
• Build and maintain Infrastructure as Code using Terraform/Pulumi across bare metal servers, networking, and cloud resources
• Create and evolve internal developer tooling — CLI tools, service templates, documentation, and guardrails
• Lead capacity planning, incident response, and SLO definition for internal platform services
• Work closely with Infrastructure, TelApps, Mobile Core, and Edge teams
• Mentor senior engineers and influence technical direction across the org
