With a focus on fostering a collaborative and inclusive work environment, VIA MATCH LIMITED emphasizes continuous learning, professional growth, and the integration of the latest AI research into practical applications.

We are seeking an experienced AI Engineer to join our expanding UK team, based in London with a hybrid working model. This senior or lead-level role offers an exciting opportunity to work on high-impact AI projects at scale, collaborating closely with top-tier clients and internal teams. The position involves designing and architecting complex AI orchestration layers that facilitate reliable and scalable deployment of large language models (LLMs) and multi-agent systems. Unlike roles focused solely on model training, this position emphasizes building robust production systems, integrating various AI components such as retrieval-augmented generation pipelines, vector databases, and agentic workflows.

The successful candidate will be instrumental in tackling some of the most technically demanding AI challenges in the industry, including multi-agent systems, retrieval-augmented workflows, and enterprise-grade evaluation frameworks. This role requires a hands-on approach, combining software craftsmanship with innovative AI engineering to deliver solutions that are both technically sound and commercially viable.

Qualifications

• Extensive hands-on experience working with LLM APIs, understanding their capabilities, limitations, and failure modes.
• Practical knowledge of Retrieval-Augmented Generation (RAG) architectures, vector databases, knowledge graphs, and prompt engineering.
• Experience in developing multi-step LLM workflows and agentic systems, utilizing frameworks like LangGraph, Strands, or custom implementations.
• Proficiency in Python, with experience in developing production APIs and services, along with familiarity with cloud platforms such as AWS, GCP, or Azure.
• Solid understanding of distributed systems, CI/CD pipelines, testing frameworks, and deployment strategies.
• Strong data manipulation skills using tools like pandas and SQL, coupled with experience in evaluating LLM-based systems.
• Ability to work effectively in ambiguous environments, optimizing non-deterministic systems through experimentation while balancing latency, cost, and quality.

Responsibilities

• Design and develop production-grade AI systems integrating LLMs, RAG pipelines, vector databases, and agentic frameworks to meet client requirements.
• Create and implement evaluation and observability frameworks to monitor system performance, accuracy, and reliability, ensuring continuous improvement.
• Implement retrieval systems, including ingestion pipelines, chunking strategies, and advanced techniques such as HyDE, to optimize data retrieval and processing.
• Build and maintain robust production AI applications, ensuring clean code, comprehensive error handling, and well-designed APIs and data pipelines.
• Develop and optimize prompts, balancing latency, cost, and quality considerations across different model providers.
• Collaborate with clients and internal teams to translate complex technical requirements into scalable and trusted AI products.

Benefits

• Competitive salary ranging from £80,000 to £110,000, commensurate with experience and level.
• Participation in a company bonus scheme that rewards performance and contribution.
• Personalized learning and development budget to support continuous professional growth.
• Choice of high-quality equipment, including Mac or PC, along with necessary accessories.
• A collaborative and inclusive work environment where your technical insights are valued from day one.
• Support and investment to pursue innovative ideas and accelerate your career progression.
• Exposure to pioneering AI projects across multiple sectors, working with enterprise clients and industry leaders.
