We are seeking a talented Backend Engineer to architect and build the next generation of our AI-powered voicebot and chatbot platform. This critical role involves leading the migration from our existing PHP/HTTP stack to a modern, scalable, real-time architecture, significantly enhancing our conversational AI products.

Key Responsibilities:

• Architect, develop, and maintain scalable, robust backend services specifically for voice and chat AI applications.
• Lead the technical migration effort from the legacy PHP/HTTP stack to a high-performance, real-time backend framework.
• Implement real-time communication features, including websockets and streaming, conversation relays, and advanced voice capabilities.
• Integrate essential 3rd party APIs such as Twilio (voice), WhatsApp, ElevenLabs, and OpenAI.
• Design, build, and maintain multi-agent orchestration frameworks for complex AI-powered conversations.
• Collaborate on CI/CD pipelines, ensuring robust monitoring, logging, and operational support.
• Work closely with AI/LLM engineers to facilitate seamless integration of AI modules.

Must-Have Qualifications:

• 3+ years of experience in Backend Engineering, preferably utilizing Python, Node.js, or similar languages.
• Proven expertise in building real-time APIs (websockets, streaming) and asynchronous programming.
• Strong experience with modern backend frameworks (e.g., FastAPI, Flask, Django) and AI/ML frameworks (Langchain, Langgraph).
• Hands-on experience working with Large Language Models (LLMs), preferably OpenAI, and knowledge of MCP.
• Experience integrating with 3rd party communications APIs (Twilio and/or Whatsapp highly desirable).
• Experience with voice technology APIs and speech synthesis (e.g., ElevenLabs, Google TTS).
• Experience integrating LLMs and exposure to multi-agent architectures.
• Familiarity with database technologies (SQL and NoSQL).

Nice-to-Have Skills:

• Experience with containerization (Docker) and cloud infrastructure (AWS, GCP, or Azure).
• Experience in CI/CD, DevOps processes, and testing tools.
• Previous work migrating legacy systems to modern stacks.
• Experience with conversational AI, chatbots, voice assistants, real-time speech processing, and telephony systems (Asterisk, FreePBX).

Benefits & Culture:

We offer a 100% remote work environment (Italy or Spain based), flexible compensation, comprehensive health insurance (location dependent), and a focus on work-life balance.
