AI Engineers (Agentic AI & LLM Modeling) | Remote (US)

We're partnering with a globally recognised professional services and technology organization that is making a significant investment in next-generation AI capabilities.

As part of a newly expanding AI Engineering function, the team is building production-grade intelligent systems that combine cutting-edge AI research with real-world enterprise deployment. This is an opportunity to work on some of the most challenging problems in modern AI, including reasoning systems, agent orchestration, model alignment, retrieval architectures, and large-scale LLM optimization.

We are hiring across two core areas:

🔹 Agentic AI Engineering

Design and build intelligent systems capable of reasoning, planning, tool use, retrieval, memory management, and multi-step workflow execution.

Areas of focus include:

• Agent orchestration and workflow design

• LangGraph and LangChain systems

• Retrieval-Augmented Generation (RAG)

• Context and memory engineering

• Evaluation, observability, and AI safety

• Production-scale AI applications

🔹 LLM Modeling & Post-Training Engineering

Develop, train, align, and optimize large language models for enterprise-scale deployment.

Areas of focus include:

• Supervised Fine-Tuning (SFT)

• RLHF, DPO, PPO, GRPO and preference optimization

• Reward modeling and alignment

• Synthetic data generation

• Evaluation and benchmarking frameworks

• Distributed training and inference optimization

What We're Looking For

• Strong Python engineering experience

• Hands-on experience building production AI systems

• Deep understanding of LLMs and modern AI architectures

• Experience with agentic systems, retrieval architectures, model alignment, post-training, or large-scale AI infrastructure

• Strong problem-solving skills and the ability to operate in highly technical environments

Why Consider This Opportunity?

• Work on genuinely cutting-edge AI engineering challenges

• Join a newly expanding and highly strategic AI function

• Build systems that move beyond simple chatbot experiences into reasoning, planning, and autonomous workflows

• Collaborate with AI researchers, engineers, architects, and technical leaders

• Competitive compensation packages

• Remote opportunities across the US

If you're passionate about building the future of enterprise AI and want to work on high-impact systems at scale, I'd be happy to arrange a confidential conversation.
