Role Overview

As a Senior AI Engineer at Trustero, you will play a crucial role in optimizing/evaluating large language models (LLMs) for reasoning and decision-making processes, as well as implementing RAG pipelines and agentic architectures/workflows.

You will work closely with our engineering team to implement cutting-edge LLM/RAG techniques that enhance the intelligence and performance of our AI driven Governance, Risk and Compliance platform.

The ideal candidate has hands-on experience integrating LLMs and working with RAG pipelines, and is passionate about applying these technologies to deliver tangible impact. Familiarity with NLP and ML methods—particularly text classification—or experience fine-tuning LLMs for specific industry verticals would be highly desirable.

Salary Range: $150,000 - $220,000 USD per year, plus stock options, based on experience and qualifications.

Key Responsibilities

• LLM Integration & Reasoning

  • Develop LLM-based reasoning techniques, including automated decision-making and context understanding.

  • Integrate LLM solutions into the core product to enhance user experiences and streamline compliance workflows.

• RAG Pipeline & Optimization

  • Proficiency in chunking large documents and creating efficient indexes for retrieval-augmented generation.

  • Experience running queries on RAG databases or vector stores to retrieve relevant context.

  • Skill in re-ranking and optimizing results to provide the highest-quality context for LLM queries.

• Collaboration & Engineering

  • Collaborate with the engineering team to integrate LLM solutions into our infrastructure, ensuring compatibility and scalability.

  • Partner with product managers and engineers to align functionality with the product vision and deliver tangible user value.

  • Conduct code reviews, write clean, maintainable code, and follow software engineering best practices.

• Continuous Improvement

  • Continuously experiment with cutting-edge ML techniques and frameworks, particularly those related to LLMs and emerging technologies.

  • Monitor and evaluate LLM system performance in production, iterating on solutions and model selection to ensure high reliability.

Salary Range: $150,000 - $220,000 USD per year.
