Ready to build AI agents that actually make it into production?

Fusion5 is looking for an experienced Senior AI Engineer to join our Applied Intelligence team. This is a hands-on role for someone who loves solving complex problems, writing production-quality code and taking enterprise AI solutions from discovery right through to deployment and operational handover.

You'll build AI solutions across a diverse range of customer challenges and complex business workflows. You'll connect AI with enterprise applications, data and tools, choosing the right combination of models, software and automation for each problem. Working alongside process consultants, architects and customer teams, you'll take solutions from early validation through to reliable operational use.

About you

You'll be customer-focused, adaptable and solutions-driven, with strong communication skills and the confidence to explain complex technical concepts clearly. You'll thrive in a collaborative environment, take ownership, make sound decisions when things are ambiguous, and enjoy solving challenging problems. You'll bring a growth mindset, welcome feedback, and be comfortable mentoring others while working closely with both technical teams and business stakeholders.

You know when to use an LLM, when deterministic code or workflow is more appropriate, and how to combine them. You can explain the trade-offs in accuracy, reliability, cost and maintainability.

About the role

Working directly with customer teams, you'll validate real business use cases, lead technical discovery and build reliable enterprise AI solutions.

You'll select the right platforms, models and frameworks, integrate agents with enterprise systems and data, and write and review production code. You'll work across the full delivery lifecycle, from discovery and experimentation through testing, production deployment, hypercare and handover.

You'll also play an important technical leadership role, reviewing solution designs and code, mentoring engineers and contributing reusable patterns, templates and accelerators to Fusion5's Agent Factory.

• Proven experience delivering production software, data, integration or AI solutions in consulting or customer-facing environments.
• Hands-on experience designing, coding and operating an LLM-based agent in production across Microsoft, Databricks, AWS or other AI-platforms.
• Experience with tool integration, evaluation, security controls, retrieval and/or orchestration.
• Strong understanding of APIs, enterprise integration, cloud security, identity, authorisation, DevOps and CI/CD.
• Experience evaluating different agent platforms, frameworks and model providers against customer requirements.
• Strong coding skills in at least one language such as Python, TypeScript, C# or Java.
• Experience leading technical delivery, reviewing production code and mentoring engineers.
• Familiarity with Model Context Protocol (MCP) and agent interoperability approaches such as A2A would be valuable.
