Job Description

Senior Software Engineer – GenAI & Scalable Systems

London (Hybrid, 2–3 days/week) | Competitive Salary + Benefits

We’re hiring for a leading consumer tech company building out a brand-new AI team and they’re looking for a senior AI engineer to help design and scale the systems behind the next wave of Generative AI-powered products.

You’ll be at the heart of a growing AI function, building real systems that support live features used by millions, with plenty of runway to grow into AI specialisation, infrastructure leadership, or both.

What They’re Looking For

• Strong software fundamentals – clean code, architecture, testing, performance
• Solid experience in backend/infrastructure engineering, ideally with Python
• Some exposure to AI/ML – through personal projects, online courses, research, or past roles
• Comfortable working cross-functionally with product, platform, and ML teams

What You’ll Be Doing

• Designing and building LLM- and NLP-based systems from the ground up
• Working on retrieval-augmented (RAG) pipelines, embeddings, and hybrid search
• Deploying and optimising GenAI features with real product applications
• Collaborating across product, engineering, and ML to deliver scalable AI solutions
• Shaping the technical foundations of a new AI team in a fast-moving environment

Why This Role Stands Out

• Work on cutting-edge GenAI applications from the ground up
• Join a new, well-resourced AI team at the earliest stage
• Immediate product impact – your work goes live, not to a research shelf
• Room to grow into AI-focused engineering or technical leadership
• Hybrid setup with real flexibility and strong cross-functional culture

If you're a strong backend engineer who’s excited by the promise of AI and ready to build the systems that power it, this is a rare opportunity to be part of something early, meaningful, and technically ambitious.
