Data Scientist - Agentic AI - Permanent UK

We are at a generational moment for technology and AI. The shift from single-model applications to autonomous, collaborative agent systems represents the most significant leap since the introduction of Large Language Models (LLMs). At Satalia, we are not just observing this transformation; we are building it. These are not experimental prototypes; they are production-grade solutions that make a tangible impact for our FTSE 100 clients and WPP agency partners, at enterprise scale., Design and deliver production-grade agentic systems, from multi-agent orchestration to the AI services and models that power them.

• Assess fit of agentic solutions per use case, being intentional in system design
• Design the most suitable orchestration pattern per use case
• Evaluate and recommend the best suited agent development framework
• Engineer multi-step agent workflows that are reliable, auditable and modular, supporting both linear and non-linear control flows
• Implement agent memory and state management systems
• Optimise context assembly for each agent interaction
• Evaluate and select the most appropriate foundation models, embeddings and context-specific model variants; apply fine-tuning or adaptation where needed
• Implement guardrails to ensure operation within ethical, legal, brand boundaries
• Build services for agent use, including ML models, GenAI and task-specific APIs
• Process multi-modal data using appropriate embeddings and vector retrieval
• Build, evaluate and maintain robust RAG and / or GraphRAG pipelines
• Implement fallback strategies (e.g., retries, backup tools, escalation, safe exits)
• Build and integrate MCP servers to expose and consume data and AI services
• Use Google's A2A protocol to support independent agent communication, designing composable service boundaries and appropriate integration patterns
• Containerise applications (Docker) - our platform team manages K8s
• Apply AgenticOps practices, including evaluation, observability, guardrails, security, performance optimisation, CI/CD, versioning, rollback, drift detection
• Design and implement testing strategies for non-deterministic behaviour
• Stay abreast of the latest AI research trends and integrate them into our products
• Maintain documentation for architectures, APIs and operational procedures
• Communicate progress, blockers, technical approaches, challenges and potential solutions to technical colleagues and non-technical stakeholders.
