Being a best-in-class SaaS Company, we understand that bringing in new ideas and innovative technology is mission critical. At BlackLine we are always working with new, cutting edge technology that encourages our teams to learn something new and expand their creativity and technical skillset that will accelerate their careers.

This role is specifically for our AI-powered Invoice-to-Cash solution, a market leading platform that uses intelligent automation to help companies collect cash faster, unlock working capital, and supercharge efficiency in their accounts receivable processes.

Make Your Mark:

As an AI Engineer at BlackLine, you will be a key player in our mission to bring autonomous finance to every company in the world. You will be at the forefront of developing and deploying innovative applications that leverage the power of Large Language Models (LLMs) and foundation models. We are looking for a candidate with a deep understanding of AI Engineering with practical experience deploying GenAI solutions at scale.

You'll Get To:

• Design, build, and deploy production-grade applications that leverage foundation models to deliver unprecedented insights and efficiency to Finance & Accounting teams.
• Develop and implement robust evaluation methodologies for open-ended AI systems, including the use of "AI as a judge" to ensure our solutions meet the highest standards of accuracy and reliability.
• Master and apply a variety of model adaptation techniques, including prompt engineering, Retrieval-Augmented Generation (RAG), and fine-tuning, to tailor foundation models to specific financial use cases.
• Create and manage datasets for training and fine-tuning models, ensuring data quality and relevance.
• Build and deploy AI agents that can automate complex financial workflows and interact with various tools and systems.
• Optimize the performance of our AI applications, focusing on reducing latency and cost to deliver a seamless user experience.
• Collaborate with cross-functional teams to identify and implement the best AI-powered solutions to address the challenges faced by the office of the CFO.

What You'll Bring:

Technical/Specialized Knowledge, Skills, and Abilities:

• Proven experience in developing and deploying applications using foundation models (e.g., GPT-4o/o3, Claude Opus 4.x / Sonnet 4.x, Llama 3.x).
• A strong understanding of the principles of AI Engineering, as distinct from traditional Machine Learning Engineering.
• Hands-on experience with prompt engineering, including techniques for few-shot and zero-shot learning, and defensive prompt design.
• Practical knowledge of Retrieval-Augmented Generation (RAG) architecture and its application in building knowledge-intensive applications.
• Experience with fine-tuning LLMs and an understanding of when to use fine-tuning versus RAG.
• Experience with building and evaluating AI agents that can perform complex, multi-step tasks.
• Familiarity with the challenges of evaluating foundation models and experience with designing and implementing evaluation pipelines.
• Proficiency in Python or C# and experience with relevant libraries and frameworks (e.g., Hugging Face Transformers, LangChain, LangGraph, PyTorch).

We're Even More Excited If You Have:

• Experience designing or operating AgenticOS patterns (e.g., memory management, tool registries, agent lifecycle orchestration, and inter-agent communication) to build reliable, production-grade autonomous agent systems.
• Knowledge of techniques for optimizing inference, including quantization and other methods to improve latency and cost.
• Expertise in multi-modal generative models (e.g., text, image, audio) and a proven ability to apply them to create innovative enterprise solutions.
• A deep understanding of dataset engineering, including data curation, augmentation, and synthesis. Proven experience in designing and building end-to-end Generative AI systems, from data ingestion and model orchestration to scalable deployment and continuous monitoring.
• A strong grasp of LLMOps principles and hands-on experience with tools and platforms for managing the entire lifecycle of Large Language Models in production.
• Experience with Model Composition (MCP) techniques, demonstrating an ability to solve complex problems by intelligently combining multiple specialized models or AI agents.
• Deep knowledge of Responsible AI principles and practical experience in implementing robust guardrails, safety filters, and ethical considerations into generative models to ensure fairness, transparency, and accountability.
• Familiarity with the financial domain and the challenges of applying AI in a regulated industry.
