THE ROLE

As a Machine Learning Engineer you'll focus on building advanced machine learning solutions for the MindsDB platform, including robust Text-to-SQL systems and optimizing Retrieval Augmented Generation (RAG) for both structured and unstructured data. Your expertise in transformer models and advanced retrieval techniques will be essential in delivering state-of-the-art LLM-driven solutions.

In this role, you'll fine-tune and deploy transformer models like Llama and OpenAI APIs, while collaborating with cross-functional teams to solve complex problems. Your experience in data structures, algorithms, and software design will help you contribute to innovative AI solutions at MindsDB, where you'll also have the opportunity to grow your skills in MLOps and model deployment.

This is a hybrid role (2-3 days in office/week) and we are looking for a candidate based in the Bay Area.

WHAT YOU’LL BE WORKING ON

Researching, building, and evaluating novel LLM-powered enterprise applications.
Developing robust Text-to-SQL systems for interacting with enterprise data sources.
Building and maintaining Retrieval Augmented Generation (RAG) systems for diverse data sources, and designing and optimizing retrieval systems for both structured and unstructured data. Experience with advanced RAG algorithms beyond naive approaches is required.
Researching and implementing advanced chunking techniques (e.g., semantic, contextual retrieval, late chunking) along with a thorough understanding of retrieval concepts such as embeddings, late interactions, query expansion, bi-encoders, and cross-encoders. Apply these techniques based on specific application needs.
Building agentic and tool-calling systems to extend the capabilities of LLMs.
Employing an "Evaluation Driven Development" approach, working with messy datasets and creating evaluation metrics.
Fine-tuning and deploying transformer models (e.g., Llama, OpenAI APIs), building agent-based applications, and integrating them into production environments.
Be capable of building a RAG system from scratch without relying on LLM frameworks, while being familiar with LLM frameworks (e.g., Langchain, LlamaIndex, DSPy) or willing to learn.
Demonstrating strong skills in data structures, algorithms, concurrency, multi-threading, and design patterns. Write clean, maintainable code.
Collaborating closely with engineers and researchers, emphasizing team collaboration, documentation, and best engineering practices. Work with cross-functional teams, manage pull requests, and participate in code reviews.
Creating design documents, technical specifications, and lead architecture discussions.

REQUIREMENTS/QUALIFICATIONS

You will have:

3+ Years of ML Engineering Experience
Proven experience in machine learning engineering, particularly with LLMs and retrieval-based systems.
Strong software engineering skills, including experience in data structures, algorithms, and software design.
Experience working with transformer models, fine-tuning, and deploying them in production.
Ability to build end-to-end machine learning systems, especially in RAG and agentic contexts.
Familiarity with LLM frameworks or a willingness to learn.
Excellent problem-solving abilities and a passion for creating innovative AI-driven solutions.
Strong communication and team collaboration skills.

Nice to have:

Startup experience with fast-paced adaptability.
Cloud platform experience (AWS, GCP, Azure) for ML deployments.
MLOps knowledge, including CI/CD and model monitoring.
Experience with big data tools (SQL, NoSQL, Spark).
Open-source contributions in LLM or AI projects.
