We're driven by a desire to transform and modernize what's antiquated, automate the manual, and solve real-world problems through innovative connectivity solutions. As a testament to our success, we're proud to stand as a financially stable and profitable company. Our robust profitability allows us not only to invest in pioneering technologies but also to foster an environment of continuous learning and growth for our team.

Our collective vision is a world where borderless connectivity fuels limitless innovation. By joining us, you can be part of laying the foundations for this interconnected future. 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.

The Role:

We're looking for a Developer Support Specialist who thrives on solving complex technical problems and building meaningful relationships with our developer community. You'll be the front line of our developer experience, providing expert guidance on Telnyx's Voice, Messaging, Wireless, and SIP APIs while fostering a vibrant, supportive community across multiple channels.

You will be responsible for delivering world-class technical support to developers integrating Telnyx products, managing our external community channels, and serving as a crucial feedback loop between our users and product teams. Your work will directly impact developer satisfaction and adoption of Telnyx's communications infrastructure platform.

In This Role You Will:

  • Be the developer's champion. Provide expert technical support across Voice, Messaging, Wireless, and SIP products, helping developers overcome integration challenges and optimize their implementations.
  • Own our community presence. Manage and moderate external-facing Slack channels and Telnyx Discord server, fostering engagement, facilitating technical discussions, and building a thriving developer ecosystem.
  • Debug and troubleshoot like a pro. Dive deep into API calls, webhook configurations, SIP traces, and code samples to identify root causes and provide actionable solutions to complex technical issues.
  • Bridge the gap between users and product. Gather, analyze, and communicate developer feedback to engineering and product teams, advocating for improvements that enhance the overall developer experience.
  • Create and maintain support resources. Develop troubleshooting guides, FAQ content, and community best practices that empower developers to solve problems independently.
  • Collaborate cross-functionally. Work closely with engineering, product, and content teams to stay ahead of product changes, validate solutions, and ensure consistent messaging across all touchpoints.
  • Monitor and improve support metrics. Track resolution times, satisfaction scores, and community engagement metrics, continuously optimizing processes to deliver exceptional developer support.

What We Value:

  • You're technically curious. You love diving into REST APIs, JSON payloads, webhooks, and SDKs. You're comfortable reading code, testing integrations, and understanding how systems connect. Bonus points for experience with SIP, WebRTC, or programmable communications APIs.
  • You're a natural problem solver. You approach complex technical issues methodically, ask the right questions, and don't give up until you find the root cause and solution.
  • You're a community builder. You understand how to nurture online developer communities, encourage healthy discussions, and create environments where developers want to engage and help each other.
  • You communicate with empathy. You can explain complex technical concepts clearly to developers at all skill levels, adapting your communication style to meet them where they are.
  • You're proactive and resourceful. You anticipate needs, create solutions before problems arise, and aren't afraid to escalate or pull in additional resources when needed.
  • You thrive in fast-paced environments. You can juggle multiple support channels, prioritize urgent issues, and maintain quality while working at startup speed.

Preferred Experience:

  • 3+ years in technical support, developer relations, or similar customer-facing technical role
  • Hands-on experience with REST APIs, webhooks, and integration troubleshooting
  • Experience managing online communities (Slack, Discord, forums) with a focus on technical discussions
  • Strong understanding of telecommunications concepts or experience with communications APIs
  • Programming experience in languages commonly used by our developers (Python, JavaScript, PHP, etc.)
  • Previous experience in a SaaS or API-first company
  • Portfolio of community contributions, technical writing, or support case studies demonstrating your problem-solving approach
