Senior AI Engineer – Agentic AI & LLMs

Senior AI Engineer – Agentic AI & LLMs

Salary: $180,000–$240,000

We are working with a fast-growing, AI-first technology business that is building production-grade AI solutions for complex, real-world industrial environments.

They are looking for an experienced Senior AI Engineer to join a high-performing team developing agentic AI systems that are already being used in operational environments.

This isn’t a research or proof-of-concept position. You’ll be building and shipping AI systems into production, owning solutions from initial prototype through to deployment, evaluation and ongoing improvement.

The Role

You will:

• Design and build sophisticated agentic AI workflows, including multi-step reasoning, tool use, retrieval and orchestration.
• Develop production applications using Claude, LangChain, LangGraph and other modern LLM technologies.
• Build and maintain LLM evaluation frameworks, golden datasets and regression testing.
• Develop production-grade RAG and retrieval systems.
• Implement observability, tracing and monitoring using tools such as LangSmith.
• Decide where LLMs add genuine value and where deterministic software is the better solution.
• Take AI products from prototype through to reliable production deployment.
• Work closely with customers and end users to understand real operational problems and translate them into effective AI solutions.
• Use modern AI coding tools including Claude Code and Cursor as part of your day-to-day engineering workflow.

What We’re Looking For

You’ll ideally have:

• Strong commercial experience building production LLM/Generative AI applications.
• Experience with AI agents, agentic workflows, tool calling and orchestration.
• Strong experience with RAG and retrieval-based architectures.
• Experience with LLM evaluation, testing and production reliability.
• Strong Python and/or TypeScript development skills.
• Experience working with model APIs such as Anthropic Claude, OpenAI or similar.
• Strong software engineering fundamentals including Git, testing and CI/CD.
• Experience taking AI applications beyond the prototype stage and operating them successfully in production.

Nice to Have

Experience with any of the following would be particularly valuable:

• LangGraph / LangChain
• LangSmith
• Vector databases
• Hybrid search and reranking
• Fine-tuning or model adaptation
• Industrial, manufacturing, aviation, energy, utilities or field-service environments
• Open-source AI projects or a portfolio of shipped AI products

Why Apply?

This is an opportunity to work on real production AI, rather than experimental GenAI projects that never progress beyond the demo stage.

You’ll join a small, highly capable team with significant ownership, working on agentic systems used to solve complex problems across asset-heavy industries.

Compensation: $180,000–$240,000
