We work across different sectors and functions and have built a world-class team that unites commercial expertise, smart strategy, and technology. If you’re passionate about building enterprise AI products from 0->1 and leading projects at the forefront of AI innovation, we’d love to meet you.

ABOUT THE ROLE:

We are looking for a Lead AI Application Engineer to integrate foundational models into innovative tools and workflows for our clients, with a strong focus on building agentic tools that adapt and respond to complex user needs. You will be at the forefront of AI-powered product development, focusing on embedding foundational models into applications, fine-tuning workflows, and ensuring seamless performance. The ideal candidate has experience working in a consulting or agency environment and thrives in dynamic, project-based work.

This is a hands-on role where you will be responsible for building and implementing systems from the ground up. You would write production-level code while defining processes and best practices for future team growth.

RESPONSIBILITIES:

  • Integrate APIs for foundational models (e.g. OpenAI, Anthropic, Hugging Face) into scalable applications;

  • Develop and optimize workflows for foundational model use cases, including prompt engineering, embedding generation, and real-time decision-making for agentic tools;

  • Implement and manage vector-based search systems and retrieval-augmented generation (RAG) setups;

  • Build and refine tools with adaptive agentic capabilities to enable autonomous decision-making and user interactions;

  • Monitor the performance of AI systems, troubleshoot issues, and improve outputs to align with client needs;

  • Collaborate with data engineers to integrate harmonized data into AI workflows;

  • Work with full-stack engineers to embed AI functionalities into user-facing applications;

  • Stay updated on the latest advancements in AI APIs, tools, and techniques to deliver innovative solutions.


REQUIREMENTS:

  • Bachelor’s or Master’s degree in Computer Science, Artificial Intelligence, or a related field;

  • Proven experience working on gen-AI projects;

  • A minimum of 6 years of professional experience in AI application development or software engineering;

  • Proven experience working in a consulting or agency environment on project-based work;

  • Advanced proficiency in Python and frameworks like LangChain for building AI-powered applications;

  • Strong knowledge of foundational model APIs and embedding techniques;

  • Hands-on experience with vector databases (e.g. Pinecone, Weaviate) and RAG workflows;

  • Familiarity with deploying AI applications in cloud environments (AWS, Azure, or GCP);

  • Ability to translate complex client needs into technical solutions using foundational models;

  • Experience building tools with agentic capabilities to adapt and automate workflows;

  • Advanced English skills, both written and verbal, with the ability to communicate effectively in an international team.


Preferred Qualifications

  • Experience with MLOps practices for managing AI systems in production;

  • Understanding of model performance evaluation and optimization;

  • Knowledge of schema design and structured data preparation for AI workflows.
