The Role: Building the Future of AI Automation 


We're hiring a Backend Engineer with a focus on Large Language Models (LLMs) and AI to join our team.

 • AI Agent Management & Evaluation: You'll manage our AI agents and ensure system availability for our internal teams. A core responsibility is designing and monitoring pipelines to evaluate agent performance, tracking conversations and outcomes to measure and improve reliability.

 • System Development: You'll build and implement robust evaluation pipelines, identify opportunities for enhancement, and implement solutions to boost efficiency and drive iterative improvements.

 • Experience: You should have at least 4 years of backend engineering experience, with a solid understanding of our tech stack (Node.js/TypeScript, Express.js, MongoDB/MySQL, AWS, and Kubernetes). Experience in a fast-paced startup environment is a big plus.

 • AI/LLM Knowledge: You must have a strong enthusiasm for AI advancements and practical experience with LLMs or AI agent frameworks. Please be ready to provide proof of your work, such as a portfolio or open-source contributions.

 • Technical Skills: You're familiar with cloud platforms (AWS, GCP, or Azure) for deploying and managing AI systems. Experience with Docker and machine configuration is also highly valued.

 • Mindset: You're a proactive problem-solver who can take initiative in a remote environment. You have excellent interpersonal skills and a passion for turning roadblocks into technical solutions.
