About the Role
We're looking for a curious, technically-minded problem solver — not someone to just close tickets.
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. 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.
What You'll Do
- 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
What We're Looking For
Must-Have
- 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
Nice-to-Have
- 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
You don’t need to tick every box - if you’re keen to learn that's the box that matters most !
