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.

Responsibilities

• 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.

Requirements

• 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.

We Offer

• Passionate, inspired people – We aim to create a culture in which people can do extraordinary work.
• Scale and opportunity – We offer the opportunity to create, influence, and complete projects at a scale that is unparalleled in the industry.
• Challenging and stimulating work – Unique work and the opportunity to join a group of creative problem solvers. Are you up for the challenge?

We believe the best work happens when we're together, fostering creativity, collaboration, and connection. That's why we’ve adopted a hybrid approach, with teams in the office around four days a week. If you require accommodations or flexibility, please discuss this with the hiring team during the interview process.

WPP is an equal opportunity employer and considers applicants for all positions without discrimination or regard to particular characteristics. We are committed to fostering a culture of respect in which everyone feels they belong and has the same opportunities to progress in their careers.
