Senior AI Engineer in London

What we do: Zero100 is a membership-based intelligence company that connects, informs, and inspires the world’s most influential C-Level Operations & Supply Chain Officers – and their teams – to unlock the true potential of the AI and Digital Revolution. Our members use Zero100’s research, advisory services, data, and peer community to sharpen strategy, challenge assumptions, and accelerate progress on their most important transformation priorities from AI adoption and digitization to resilience and decarbonization.

What you will do: Note that this is a primarily office-based role (~4 days per week). As a Senior AI Engineer at Zero100, you will play a central role in building and scaling the AI/ML and agentic systems that power our research, product, and member-facing teams. You'll be hands-on across the full stack: designing and operating data pipelines, building production-grade intelligent systems, and prototyping new approaches to enhance our capabilities. This is an end-to-end role where you'll own projects from ideation to production, working collaboratively with a senior engineering lead while having the autonomy to drive work forward independently. You'll partner closely with colleagues in research, product, membership, and revenue operations, thriving in an environment where you can balance engineering rigour with experimentation and help shape our technical foundations as we scale.

Responsibilities:

• Design and build production-grade AI/ML and agentic systems, including agent orchestration, tool integration, and retrieval-augmented generation.
• Develop and operate scalable, reliable data pipelines that serve both AI/ML systems and broader research and analytical needs across the organisation.
• Collaborate with a senior engineering lead to architect and iterate on system designs, while taking ownership of implementation and delivery.
• Build and maintain robust infrastructure with a focus on deployment, monitoring, and long-term maintainability.
• Conduct exploratory prototyping of new AI/ML approaches to inform product direction and system design.
• Work closely with research, product, and member-facing teams to understand data requirements and deliver clean, reusable data products.
• Champion best practices around data architecture, governance (e.g., Unity Catalog), and performance tuning.
• Contribute to engineering standards, documentation, and processes as the team scales.

Requirements:

• 5 years of experience in data and ML engineering roles, ideally in startup or high-growth environments, with a track record of owning end-to-end projects.
• Experience building production-grade data pipelines and AI/ML systems (primarily in Python and SQL) in cloud environments, with an emphasis on scalability, code clarity, and long-term maintainability.
• Hands-on experience with Databricks, Spark, especially Delta Lake, Unity Catalog, Mlflow.
• Experience working with Knowledge Graphs and building Graph Databases.
• Deep familiarity with cloud platforms, particularly AWS and Google Cloud.
• Experience deploying and monitoring ML models in production, including CI/CD practices, containerization, and API development.
• Ability to deploy Opensource LLMs on local hardware or cloud platforms.
• Strong software engineering fundamentals: version control, testing, code review, and documentation.
• A genuine interest in agentic AI systems and emerging LLM-based architectures and frameworks such as Langchain/Langgraph/Deepagents.
• Proven ability to manage production infrastructure and data architecture in a fast-paced environment.
• Strong communication skills and ability to work with stakeholders to understand needs and explain complex ideas clearly.
• Comfortable with ambiguity and excited to help shape processes, standards, and infrastructure as we scale.

Benefits:

• Competitive salary and bonus scheme.
• Unlimited holidays.
• Private healthcare & Life Insurance.
• Enhanced pension.
• Enhanced Parental Leave Policy.
• Custom designed offices in central London with free breakfasts & snacks.
