AI Engineer

Particle41 is seeking an AI Engineer to design, develop, and deploy machine-learning and deep-learning models, including generative AI, while building scalable data pipelines and partnering with clients and data teams to deliver production-ready solutions. This remote role sits at the intersection of cutting-edge AI techniques and tangible business outcomes, offering opportunities to shape how clients leverage analytics across industries.

Responsibilities

• Oversee the full lifecycle of AI and ML models, from data ingestion and preprocessing through training, evaluation, deployment, and ongoing monitoring.
• Develop generative AI solutions including retrieval augmented generation (RAG), agentic workflows, MCP servers, and conversation AI agents aligned with business goals.
• Collaborate with data engineering teams to build and maintain data pipelines, feature stores, and orchestration frameworks.
• Integrate AI models into production systems via APIs, microservices, and cloud deployments.
• Optimize models and solutions for performance, scalability, robustness, and cost efficiency.
• Monitor production performance for drift, bias, fairness, and reliability, implementing remediation as needed.
• Document model designs, experiments, data provenance, and solution rationale.
• Stay informed on the latest AI/ML research, frameworks, and tools (including LangChain, LangGraph, MCP Clients/Servers, Agents SDKs, LiveKit) and propose innovative ideas.
• Engage directly with clients to understand problem statements, translate business requirements into AI solutions, and clearly communicate results.

Requirements

• Bachelor's or Master's degree in Computer Science, Engineering, Data Science, or related field.
• Minimum 3 years of hands-on AI/ML model development and deployment experience.
• Strong Python programming skills and experience with major ML/AI frameworks such as TensorFlow, PyTorch, scikit-learn, LangChain, and LangGraph.
• Experience with vector databases (Pinecone, FAISS), RAG, and agentic workflows.
• Experience building or fine-tuning large language models (LLMs).
• Proven track record deploying models to production, including REST APIs, microservices, and monitoring.
• Familiarity with Text-to-Speech and Speech-to-Text technologies (e.g., Deepgram, ElevenLabs, Cartesia).
• Experience in computer vision, time-series modeling (ARIMA, Prophet), or multimodal AI.
• Understanding of MLOps tools and frameworks (MLflow, Kubeflow, SageMaker).
• Strong foundation in algorithms, data structures, statistics, and core machine-learning principles (classification, regression, clustering, deep learning, sequence models).
• Ability to thrive in a fast-paced, dynamic environment with changing priorities.
• Publications, open-source contributions, or personal AI/ML projects.
