The Role

At Telnyx, we empower companies to build scalable, global communications products. As a Technical Implementation Engineer, you’ll work directly with our onboarding customers to implement, optimize, and execute their integrations on to the Telnyx platform. You won’t just help customers get started—you’ll be their partner in solving complex telecom and connectivity challenges.
From embedding real-time messaging into global FinTechs to scaling secure voice and AI infrastructure for HealthTech platforms, your work will shape how companies communicate at scale.
This is a hands-on, technical role where you'll act as a bridge between our cutting-edge telecom APIs, Mission Control Platform, and the real-world business systems of our customers.

Responsibilities

• Own technical implementation end-to-end: You’ll lead onboarding for customers, translating their goals into technical success and custom configuration on the Telnyx platform.
• Develop solutions: Whether integrating SIP trunks with cloud PBXs or optimizing webhook delivery pipelines, you'll solve customer challenges using code, configuration, and creativity.
• Collaborate cross-functionally: Partner with Solutions Engineers, Product, and Support to ensure customer success through deployment and beyond.
• Deploy with impact: The cutting edge of AI innovation today is in real-time communications and your work will support those businesses and more.
• Continuously improve: Use customer feedback, onboarding metrics, and your own insights to iterate on the implementation process and help scale our technical onboarding playbooks.

What We’re Looking For

• Technical Expertise: Proficiency with APIs, telecom systems (e.g. SIP, WebRTC, call routing), and cloud platforms. You’re comfortable writing and debugging code in Python, JavaScript, or similar.
• Systems Thinker: You can architect how Telnyx fits into a customer’s broader tech stack and anticipate integration challenges before they surface.
• Problem Solver: You love untangling technical puzzles and building solutions that stick.
• Customer-Facing Engineer: You’re just as comfortable diving into packet captures as you are leading a technical onboarding call with a CTO.
• Adaptable Collaborator: You thrive in dynamic, high-autonomy environments where each customer is different and the playbook evolves daily.
• Experience: 2 years in a technical role—implementation engineering, customer engineering, solutions architecture, or a similar capacity.

Bonus Points For

• Experience in telecom, VoIP, or programmable communications
• Familiarity with authentication protocols (e.g., OAuth, token-based auth)
• Experience with tools like Postman, Wireshark, or SIP debuggers
• Fluency in other EMEA languages (French, German, etc.)

• Share Options
• 401(k): Human Interest Plan w/ 4% Company Match (Eligible After 3 Months)
• Healthcare & Dental: Company Covers 50%
• Flexible Paid Time Off (Flex PTO)
• And More
