About Open Intelligence: Open Intelligence (OI) is one of WPP’s most strategic bets — a data and AI initiative at the intersection of machine learning, advertising technology, and audience insight, built to power the next generation of media intelligence. OI operates at real scale, running across the US and UK and expanding rapidly across EMEA and APAC. Our Copenhagen team has ~50 people, including 14+ data scientists and a strong engineering group. We’re flat, high-trust and fast-moving: strong opinions loosely held, teamwork over ego, aim high and have fun. Why we're hiring: Open Intelligence is accelerating the development of its core AI capabilities, and we are strengthening our applied-AI and engineering group in Copenhagen. We need a Senior Engineer who can bridge the gap between AI experimentation and production software engineering — taking cutting-edge model research, multimodal embeddings, and agentic tools, and turning them into scalable, robust, and well-architected components that power products across WPP globally. We are looking for a Senior Engineer who cares about architecture and code quality as much as the AI. You write code others can build on, reason confidently about system design, and enjoy taking something experimental and making it robust. You hold a high bar but stay pragmatic — you ship incrementally and get value out early. We lean toward an engineering-minded profile, but a strongly technical data scientist or ML engineer with the same instincts is very welcome. What you'll be doing: Build and evolve the embedding spaces from off-the-shelf multimodal models. Build the MCP server and the agent/UI on top of it. Write high-quality, tested, well-architected code that others can build on. Work closely with data scientists and engineers across OI, turning experimental work into robust components. Contribute to technical direction and help raise the bar on design and quality. Who you'll be working with: You’ll join a small, sharp team working at the embedding and applied-AI layer of OI. We work fluidly across a few closely-collaborating teams, so exact ownership flexes — but this is what the team is building right now: Embedding spaces — using off-the-shelf multimodal models (text, image, video) to build well-designed, well-distributed embedding spaces that serve several downstream use cases. Not models trained from scratch — carefully engineered spaces that make the rest of OI’s AI work. An MCP server — the tool layer that exposes these capabilities to agents and applications. A chat agent + UI on top — turning those capabilities into something people can use and be impressed by. It’s a team-centric setup: the team grows and delivers together, and the remit evolves as OI does. The work spans clean architecture, high-quality code, and applied AI. What you'll need: 5+ years in software or ML engineering, with a strong track record of well-designed, well-tested systems. Strong Python, and cloud experience (ideally GCP — Vertex AI, Cloud Run, BigQuery). Comfort with modern AI building blocks: embeddings and vector search, LLM tooling and agents (MCP a plus). Solid architecture and system-design instincts; clean, testable code as a default. A strong communicator who works well across engineering and data science. Success attributes You untangle ambiguity rather than being intimidated by it. Pragmatic perfectionist: high standards, incremental delivery. Low ego, high trust; you make the people around you better. Thrive in a fast-paced, flat, entrepreneurial environment. Who you are: You're open : We are inclusive and collaborative; we encourage the free exchange of ideas; we respect and celebrate diverse views. We are open-minded: to new ideas, new partnerships, new ways of working. You're optimistic : We believe in the power of creativity, technology and talent to create brighter futures or our people, our clients and our communities.
