The Customer Support Engineer will handle technical support for our customers, helping developers with API integrations, troubleshooting message delivery across SMS, RCS, voice, and WhatsApp, and working with carriers and vendors when an issue requires escalation. This is a technical support role. Finding the cause of a problem usually means reading logs, delivery receipts, and carrier responses, and understanding how the customer built their integration. The fault may be in the customer's code, in our platform, or with a downstream provider. Part of the job is determining where the problem actually exists and driving it to resolution. AI tools and automation are part of the daily workflow. You will work directly with US customers and the US management team. Because we are a small company, the role is broader than support alone. You may also run product demos, help the sales team with technical questions, contribute to product ownership, and pass customer feedback to the product team. This is a hands-on position. The successful candidate must be comfortable working directly with customers, reading API documentation and logs, and owning an issue from the first report through root cause and resolution. Titles for this work vary from company to company. If your current title is manager, team lead, or customer success and your daily work is hands-on technical support,
