Job description

Eligibility: Must be a U.S. Person (required for access to an ITAR / export-controlled

About the Role

We are hiring a Senior AI / LLM Engineer to design and build LLM-powered features and

applications across a range of use cases. You will work hands-on across the modern AI

engineering stack — retrieval, integration, evaluation, and production hardening — and take

ownership of significant pieces of the system from design through deployment. Retrieval-

augmented generation over large, real-world enterprise data is a prominent part of the work,

alongside platform integration and LLM-driven analysis. You will set technical direction within

your area, make sound trade-offs under ambiguity, and help raise the bar for engineers around

you.

What You’ll Do

• Own the design and delivery of LLM-powered features end-to-end — from problem framing and architecture through production deployment and iteration.
• Build and tune retrieval-augmented generation (RAG) pipelines over large, heterogeneous enterprise data — ingestion, chunking, embeddings, indexing, and entity/relationship modeling — with a focus on retrieval accuracy and closing coverage gaps.
• Design and build data ingestion and indexing pipelines that reliably capture content, map identities across systems, and support incremental/resumable sync at scale.
• Integrate LLMs (via managed platforms such as Amazon Bedrock) for question answering, analysis, and other tasks, preserving sessions, sources, and citations.
• Integrate with enterprise platforms and collaboration tools through their APIs, including SSO/OAuth flows and event-driven bot/app patterns.
• Design permission-bounded access and correct attribution in multi-user contexts, so the system never surfaces data a user could not already access.
• Establish evaluation practices for retrieval quality and answer correctness, and use them to drive iteration and catch regressions.
• Add observability, logging, and audit trails, and lead debugging of quality and performance issues in production.
• Guide and mentor other engineers through design and code reviews, and contribute to shared standards.

Required Qualifications

• 6–8 years of software engineering experience, with at least 2 years building with LLMs or applied ML in production.
• Strong proficiency in Python (or comparable) and strong engineering fundamentals — testing, version control, clean and maintainable code.
• Deep hands-on experience with RAG systems: embeddings, vector databases, chunking/indexing, and a strong track record diagnosing and improving retrieval quality.
• Experience designing and building data ingestion/ETL pipelines over large, messy, real-world datasets.
• Strong experience integrating third-party APIs into backend services, including authentication flows (OAuth/SSO) and webhook/event-driven patterns.
• Hands-on experience with LLM APIs (e.g., Anthropic, OpenAI, or similar) and/orchestration frameworks.
• Experience building and relying on evaluations for model and retrieval outputs.
• Experience with knowledge graphs or entity-relationship modeling for retrieval.
• Experience building multi-user or multi-tenant systems with scoped permissions and audit requirements.
• Familiarity with observability and tracing for LLM or data pipelines.
• A rigorous approach to data access, permissions, and handling sensitive information.
• Experience taking systems to production on a major cloud platform (AWS preferred), and a track record of owning features independently.

Preferred Qualifications

• Experience with Amazon Bedrock or other managed LLM platforms.
• Experience integrating with enterprise collaboration platforms (chat, wikis, ticketing) via their APIs.
• Bachelor’s or advanced degree in Computer Science, Engineering, or a related field — or
