Senior AI Engineer

Reforge

205d • $190,000 - $220,000 • Remote

About The Position

As an AI Engineer at Reforge, you will play a key role in shaping how our platform uses large language models to deliver value to customers. You’ll focus on building and improving LLM-powered products and features – from crafting high-quality prompts to evaluating and tuning model outputs for optimal performance. This is a highly collaborative, product-focused role where you’ll work closely with product managers and engineers to turn cutting-edge AI capabilities into practical features. This position is fully remote, so we’re looking for someone who is self-motivated and excels at clear, asynchronous communication within a distributed team.

Requirements

• Technical Skills: Proficiency in programming with TypeScript (for backend development) and familiarity with Python for ML tasks or prototyping. Comfort working with APIs, databases, and cloud services.
• LLM Expertise: Strong understanding of large language models (e.g., GPT series) and best practices in prompt engineering.
• ML & NLP Knowledge: Solid foundation in machine learning, especially natural language processing techniques, and experience applying them to solve real-world problems.
• AI Tooling: Experience with vector databases, embedding frameworks, and RAG pipelines.
• High Agency: A self-starter attitude with a high degree of autonomy – able to take ownership of projects, experiment, and drive solutions with minimal direction.
• Product Mindset: Sharp product intuition and user empathy. You think critically about how features will be used, and you strive to create the best possible user experience.
• Growth Mindset: Passion for continuous learning and staying updated on the latest AI/LLM advancements. We value ability and initiative over years of experience – motivated candidates with a strong drive are encouraged to apply.
• Communication: Excellent communication skills in English, especially in writing. You can clearly articulate ideas and collaborate asynchronously in a remote environment.

Responsibilities

• Prompt Engineering: Design, experiment with, and refine prompts and system instructions to maximize the effectiveness and reliability of LLMs across Reforge’s products.
• LLM-Powered Features: Collaborate with product and engineering teams to develop and integrate new backend features powered by LLMs, enhancing our Insight Analytics platform with intelligent capabilities.
• Continuous Improvement: Continuously evaluate the quality of LLM outputs via internal testing and user feedback. Iterate on prompts, model settings, or data pipelines to improve performance over time and deliver a better user experience.
• Model Evaluation: Design and implement evaluation frameworks to assess LLM performance across different use cases. Monitor key metrics and develop automated testing pipelines to ensure consistent quality.
• Coding & Integration: Write and maintain code (primarily in TypeScript, with some Python) to implement support for LLM interactions – including building retrieval-augmented generation (RAG) pipelines, working with vector embeddings, and handling content chunking of large documents. A majority of your work will be in-code shipping product — not in prompting tools or notebooks.
