Role
Who you are
- We're looking for a curious, technically-minded problem solver — not someone to just close tickets
- A background in software engineering, networking, or a related technical field (however you got there) is ideal — We care about what you can do, not where you learned it
- Background in Computer Science, IT, networking, or equivalent hands-on experience
- Networking fundamentals: solid understanding of how the internet works, including DNS, routing, IP addressing, and HTTP/HTTPS
- API experience: comfortable with REST APIs, webhooks, and tools like Postman or cURL
- Linux terminal proficiency: comfortable navigating filesystems, reading logs, and running commands
- Problem-solving mindset: you dig into issues, ask good questions, and don't give up easily
- Communication skills: you'll need to be highly proficient in English, both written and verbal - owning customer communication and technical documentation from day one
- You don’t need to tick every box - if you’re keen to learn that's the box that matters most !
Desirable
- Familiarity with scripting or programming (Python, Bash, JavaScript, or similar)
- Understanding of AI concepts such as RAG, MCPs, embeddings, and prompt engineering
- Experience using n8n, Zapier, Git/GitHub, or similar
What the job involves
- You'll troubleshoot complex customer issues across voice, messaging, APIs, IoT, and AI products, digging into networking problems, debugging integrations, and analysing logs alongside engineering teams
- But this role goes further: we're building an AI-first support model, and as you develop product expertise, you'll help shape it — building bots, automating workflows, and turning repetitive tasks into cron jobs. If you've ever spotted a repetitive task and actually built the fix for it, you'll fit right in
- Troubleshoot: complex customer issues across networking, APIs, and communications products
- Investigate: using tools like Postman, cURL, Wireshark, Linux terminal and our internal tooling
- Collaborate: with customers, vendors, and engineering teams to resolve cases
- Automate: contribute to bot-building and workflow automation
- Document: solutions and improve self-service resources
- Learn: VoIP protocols, internal systems, and new technologies as the role evolves
- Your Toolkit
- Troubleshooting: Postman, cURL, Wireshark, sngrep, Linux terminal
- Ticketing and Comms: Zendesk, Slack
- Collaboration: Google Workspace (Gmail, Calendar, Docs, Sheets, Meet)
- Automation: n8n, Zapier, OpenClaw (internal AI platform), scripting (Python, Bash, etc.)
- Version Control: GitHub
- Analytics: Metabase, Graylog, Jira
- This role operates on Central Time (UTC+1), 9am–6pm Monday to Friday
Our take
As businesses increasingly look to integrate AI into customer interactions, one major challenge has emerged: the underlying infrastructure isn't build for real-time performance. Many companies rely on a patchwork of providers for voice, messaging, and AI, which can introduce delays, complexity and reliability issues. This becomes especially problematic for use cases like voice assistants or automated calls, where even slight latency can disrupt the experience.
Telnyx offers a full-stack platform that combines telephony, networking and AI infrastructure into a single system. In simple terms, it gives businesses everything they need to build and run real-time, AI-powered voice applications without stitching together multiple vendors. Its platform supports things like AI voice agents, programmable calls and messaging, all designed to work quickly and reliably across global networks.
The company now serves over 14,000 customers, processes millions of API requests daily and operates infrastructure across more than 60 countries. Recent recognition from Frost & Sullivan and partnerships likes it deal with Telarus point to growing enterprise adoption too. And as more businesses move toward AI-driven communications, Telnyx is positioning itself as the underlying infrastructure layer that makes those experiences fast and dependable.
