Junior AI/ML Engineer

Description

We are hiring Junior AI/ML Engineers to help build AI agents that handle customer conversations through voice and chat.

You'll work on the retrieval, orchestration, APIs, and integrations behind these systems, helping turn working prototypes into reliable production solutions. You'll collaborate with full-stack engineers, CX designers, and operations teams to develop AI-powered experiences that are practical, secure, and effective.

We welcome candidates with relevant professional experience, internships, research, or hands-on projects who are eager to develop their skills and contribute to real-world AI applications.

What You'll Do

-
Build AI agents: Develop conversational agents that interact with users, call tools and APIs, and hand conversations off to human agents when needed.

-
Develop retrieval pipelines: Build retrieval-augmented generation (RAG) pipelines that help AI agents answer questions using approved information sources.

-
Integrate systems: Connect AI agents with CRMs, ticketing systems, databases, and messaging channels.

-
Build and manage APIs: Work with API gateways, authentication, rate limits, and versioning.

-
Support voice AI development: Help build voice agents using speech-to-text, large language models (LLMs), and text-to-speech in English and Spanish.

-
Test and improve quality: Use evaluations, automated tests, and guardrails to improve accuracy, reliability, and safety.

-
Support deployment and monitoring: Ship and maintain solutions through CI/CD, monitoring, and documentation.

-
Collaborate across teams: Work with engineering, CX design, and operations colleagues to turn prototypes into production-ready solutions.

Our Technology Stack

Our primary cloud platform is Microsoft Azure, but experience with AWS or Google Cloud is also valuable.

Relevant technologies include Python, Git, Docker, SQL, LLM APIs, agent frameworks, RAG pipelines, REST APIs, API gateways, webhooks, messaging systems, and cloud-based AI services.

Experience with any one of the named tools in each relevant area is sufficient. You don't need to have used every framework or platform listed.

Working Environment

This is a fully remote opportunity for candidates based in Colombia or Mexico. You'll work with full-stack engineers, CX designers, and operations teams to build and improve AI-powered customer conversation solutions.

We value curiosity, practical problem-solving, collaboration, and a willingness to learn. You'll have the opportunity to contribute to AI agents, retrieval systems, integrations, and voice AI applications while developing your engineering skills.
