You Role and Purpose
As a Founding AI Fullstack Engineer at Orbio, you will be the technical architect and backbone of our intelligent HR platform. Your primary focus will be backend development using Python/Django, designing scalable AI-native architectures to orchestrate complex, autonomous recruitment workflows. You will leverage cutting-edge AI-assisted development tools like Cursor and Claude Code to rapidly prototype and ship complete full-stack features with minimal handoffs.
This is a unique opportunity to build production-grade conversational AI systems integrating LLMs, building our agent framework, using real-time voice and telephony interfaces, and zero-touch recruitment automation.
Key Responsibilities
* Architect and develop robust Python/Django backend systems for AI-driven HR workflows, multi-agent orchestration, and real-time conversational AI.
* Design and implement agentic AI workflows involving planning, context engineering, intent detection and intelligent tool calling to automate recruitment processes end-to-end.
* Build and scale conversational AI components including agentic workflows, speech-to-text (STT), text-to-speech (TTS), telephony integrations (Twilio), and voice activity detection.
* Utilize AI-assisted coding tools (Cursor, Claude Code) to accelerate full-stack feature development from backend APIs to frontend UIs.
* Ensure high code quality, implement monitoring and alerting, and maintain production reliability while shipping rapidly.
* Collaborate directly with the founders to align technical development with product vision and business goals.
Required Qualifications & Experience
* Expert-level proficiency in Python with extensive experience in Django, Django Channels, FastAPI, ASGI, and async programming.
* Strong system design skills and ability to articulate technical trade-offs.
* Proven skills in building scalable backend systems handling 100+ concurrent AI workflows with low latency.
* Deep knowledge of LLMs including prompt engineering, chaining, caching, fine-tuning, and usage of open-source (Llama, Mistral) or closed-source models (OpenAI, Anthropic).
* Experience with retrieval-augmented generation (RAG), vector databases and semantic search implementations.
* Familiarity with AI agentic frameworks, multi-agent orchestration, planning and reasoning systems.
* Hands-on experience integrating speech-to-text, text-to-speech, telephony (Twilio, IVR) and voice activity detection into production systems.
* Proficiency with AI-assisted development tools and ability to deliver full-stack features (backend + frontend) efficiently.
* Good frontend skills with JavaScript/TypeScript and React (AI-assisted vibe coding).
* Understanding of asynchronous message queues (Celery, RabbitMQ/Redis) and data storage technologies (PostgreSQL, Redis).
* English and Spanish fluency
Desired Skills
* Experience with DevOps practices: CI/CD pipelines, containerization (Docker), cloud platforms (AWS, Azure).
* Knowledge of production monitoring, logging, alerting, and security best practices for enterprise B2B AI solutions.
* Familiarity with multi-modal conversational interfaces and fallback mechanisms for robust production deployment.
* Passion for working in fast-paced startup environments with a hands-on, ownership-driven mindset.
