About the Role

We are looking for a hands-on AI Engineer to contribute to our Voice AI Testing & Evaluation Platform. You should be comfortable understanding an existing codebase quickly, independently owning development tasks, and delivering reliable features with minimal onboarding.

This role focuses on backend development, LLM-powered workflows, AI agents, and automated evaluation. Practical experience building production AI applications is more relevant than model training, deep learning research, or academic projects alone.

Key Responsibilities

- Build and maintain Python backend services and FastAPI-based REST APIs.
- Integrate LLM providers, voice platforms, and other third-party APIs.
- Develop asynchronous workflows using asyncio, concurrency, and parallel API calls.
- Build and improve AI agents using LangChain, LangGraph, or similar orchestration frameworks.
- Implement automated evaluation workflows, including LLM-as-a-Judge, hallucination detection, guardrails, and scoring.




- Support voice-agent testing workflows involving speech-to-text (STT), text-to-speech (TTS), and conversation evaluation.
- Implement background jobs, queues, retries, timeouts, and error handling.
- Debug issues, improve system reliability, and own assigned tasks through implementation, testing, and delivery.

Required Skills

- Strong practical experience with Python, FastAPI, REST APIs, and backend integrations.
- Hands-on understanding of asynchronous programming, asyncio, and concurrency.
- Experience building LLM-powered applications, AI agents, and prompt-driven workflows.
- Practical experience with LangChain, LangGraph, or equivalent frameworks.
- Understanding of LLM evaluation methods, evaluation metrics, hallucination detection, and automated scoring.
- Ability to design reliable workflows involving parallel requests, background processing, queues, and retries.
- Strong debugging and problem-solving skills, with the ability to work independently.

Preferred Skills

- Exposure to voice agents and STT/TTS pipelines.
- Experience with Bland AI, Deepgram, ElevenLabs, Twilio, or similar platforms.
- Experience implementing LLM-as-a-Judge, guardrails, or automated AI testing systems.
- Prior experience developing and supporting production AI applications.
