We're currently seeking passionate individuals who are excited about the opportunity to contribute to an industry-shaping company while growing their own skills and careers.
About You
You are a seasoned platform engineer who thrives on building the foundational layer that enables other engineers to move fast with confidence. You think in systems, care deeply about developer experience, and have strong opinions about infrastructure that you can back up with experience. You've operated production systems at scale, led architectural decisions that outlasted your tenure, and mentored engineers who went on to do the same.
The Opportunity
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.
In This Role You Will
• 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
Who We're Looking For
• 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
Bonus Points
• 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)
