Senior Forward Deployed Engineer (AI Agent) – UK

Cresta is hiring a Senior Forward Deployed Engineer (AI Agent) to join our remote team across the United Kingdom, where you'll bring production-grade AI agents to life inside some of the world's most demanding enterprise environments. This is a hands-on engineering role for builders who want to see their work create measurable impact for real customers.

About the Role

On Cresta's AI Agent team, your mission is to design and ship state-of-the-art AI agents that solve concrete business problems. Working at the intersection of cutting-edge Large Language Models and agentic systems, you'll partner directly with customers alongside our software and machine learning engineers to deliver deployments that are reliable, secure, and cost-efficient. Expect to build intelligent agents, connect them to the systems customers already rely on, and feed everything you learn back into our core platform. The position rewards strong technical instincts, adaptability, and genuine enthusiasm for putting AI to practical use.

Key Responsibilities

• Build, configure, deploy, and tune AI agents using Cresta's platform and tooling.
• Integrate agents with external systems such as APIs, databases, and CRMs for smooth end-to-end workflows.
• Optimize agent performance through prompt and configuration refinement, and resolve issues in complex enterprise settings.
• Translate business needs into technical requirements by collaborating with customers and internal stakeholders.
• Run interactive demos and proof-of-concepts, collect feedback, and iterate toward customer goals.
• Set milestones, draft implementation plans, and coordinate delivery across internal teams.
• Close the loop with product and engineering — surfacing gaps, creating custom tooling, and shaping the roadmap with deployment insights.
• Act as a trusted technical advisor on agent architecture, security, scalability, and adoption best practices.

Qualifications

• Bachelor's or Master's in Computer Science, Engineering, or a related discipline.
• 3+ years in software development, consulting, AI/ML engineering, system integration, or a forward deployed engineering capacity.
• Strong proficiency in Python and Golang, with clean, efficient coding habits.
• Familiarity with AI/ML concepts; hands-on experience with LLMs and prompt engineering strongly preferred.
• Solid grasp of AI agent frameworks, function calling, and retrieval-augmented generation (RAG), ideally from building such systems.
• Experience with cloud platforms (AWS, GCP, or Azure) and DevOps practices including CI/CD, containerization, and monitoring.
• Proven integration skills using APIs, webhooks, and data pipelines.
• Excellent communication, project management, and data-driven decision-making (A/B testing, performance monitoring).
