AI Engineer

Why This Role Matters

You'll join a small, high-impact team expanding Banyan's core platform with applied AI – including work in document parsing, data extraction, generative AI, and conversational interaction with complex financial and operational data. This is a foundational role and a rare chance to deeply shape and define how applied AI transforms the financing of sustainable infrastructure.

What you’ll do:

• Design and implement AI-powered services using modern paradigms like Model Context Protocol (MCP), Retrieval-Augmented Generation (RAG), Reasoning and Acting (ReAct), and agentic frameworks to automate complex financial analysis and due diligence workflows.
• Develop secure, scalable, and maintainable APIs (primarily Python; Java experience also valued).
• Collaborate closely with the existing two-person AI pod to explore, prototype, and productize AI solutions.
• Integrate with LLM APIs (OpenAI, Gemini) and vector databases to enhance automation initiatives.
• Partner cross-functionally with Product, Customer Success, and Sales teams to identify opportunities for AI assistance and build AI expertise across the company.
• Advocate for and apply healthy coding practices and Agile methodologies.
• Participate actively in code reviews, pair programming, and knowledge development to implement new code and debug existing systems.
• Provide 2nd tier production support and proactively identify ways to improve our systems.
• Build financial and cleantech subject matter expertise and stay abreast of new AI technologies and industry trends to inform engineering decisions.

What you’ll need:

• Strong programming experience in Python or Java; comfort in learning the other.
• Demonstrated experience with LLMs, AI APIs, or applied ML workflows.
• Solid understanding of REST APIs, testing frameworks, and cloud deployment (AWS preferred).
• Provide thought leadership that challenges existing processes and delivers clear, structured decision-making frameworks to evaluate implementation tradeoffs.
• Curiosity, pragmatism, and ability to move from prototype to production.
• Clear communicator who enjoys solving problems collaboratively.
• Genuine enthusiasm for Banyan's mission and a willingness to help and mentor other team members.
• Bachelor's degree required.

Bonus skills:

• Experience with Postgres or other modern relational databases.
• Familiarity with Vue.js or modern front-end frameworks.
• Prior experience in financial services or FinTech.
• Exposure to data pipelines, document parsing, or retrieval systems.

How we’ll support your growth and success:

This is more than a job—it's a chance to build expertise at the intersection of fintech and climate tech.

• Direct exposure working closely with founders, executives, and cross-functional teammates.
• Develop cutting-edge industry expertise in fintech, capital markets, and clean infrastructure deployment.
• You will be working on a meaningful product that is actively accelerating clean infrastructure deployment around the world.
• Learn from and with a diverse team of smart, passionate people.
