About The Company
Insait is revenue-generating conversational AI for enterprises where customer interactions drive revenue, including the most regulated industries in the world. Most companies are sitting on revenue they cannot see. They know their conversion rates. They do not know which conversations are winning and why, or how to replicate the difference at scale. The AI most organizations have tried was not built to close that gap. It deflects. Heavy build cycles, platforms optimized for volume rather than revenue. Insait was built to close the actual gap. We reverse-engineer what your best people do and deploy it everywhere a revenue conversation happens: every call, every chat, every form. Built from your existing interactions. Live in weeks. Every customer gets your best person, every time. Always.
About the Role

Insait is redefining how financial institutions engage with their customers using AI. Our platform leverages advanced LLM technology to power enterprise-grade conversational agents that drive revenue outcomes across lending, deposits, and customer engagement.

We work with 30+ global financial institutions, including leading banks and insurance companies, and have already reached millions of dollars in ARR.

Insait is currently finalizing a $20M Series A round led by top-tier investors, and we’re scaling rapidly to meet growing demand from enterprise clients across the US and globally.

This is a rare opportunity to join an AI company at an inflection point — building real production systems used by some of the largest financial institutions in the world.


About the Role:

We’re looking for a LLM Solutions Engineer who can bridge business problems and cutting-edge AI technology.

In this role you will work directly with enterprise clients and internal teams to design and deliver LLM-powered workflows that solve real business challenges. You will combine prompt engineering, workflow design, evaluation frameworks, and experimentation to ensure solutions perform reliably in production environments.

This is a hands-on role in a fast-moving startup, ideal for someone excited about applying LLM technology to real-world enterprise use cases at scale.


Responsibilities:

  • Partner with customers and internal teams to translate business requirements into LLM-powered workflows.
  • Design, refine, and optimize high-quality prompts and automated flows that solve real-world enterprise use cases.
  • Build structured evaluation plans to test workflows against accuracy, reliability, and compliance standards.
  • Identify and resolve edge cases to ensure consistent, production-ready performance.
  • Collaborate with engineering, product, and data teams to iterate quickly and drive product improvements.
  • Act as an advocate for best practices in LLM development, ensuring solutions meet enterprise-grade expectations.

Requirements


  • 3+ years of experience working with LLMs or generative AI APIs (OpenAI, Anthropic, etc.).
  • Strong expertise in prompt engineering and workflow design, with proven ability to optimize for performance.
  • Experience translating complex business requirements into technical solutions.
  • Familiarity with testing/QA methodologies for AI workflows — automation experience is a plus.
  • Excellent communication skills and ability to engage with customers directly.
  • Passion for LLMs, with a fast-learning mindset and a desire to build innovative AI-driven products.
  • High proficiency in English.
  • Flexibility and willingness to work on-site at customer locations for extended periods (3–12 months), depending on project requirements.


Nice to have:

  • Experience building AI solutions for enterprise environments
  • Background working with financial institutions or regulated industries
  • Familiarity with Python or workflow automation tools
