The Role

We are seeking a Senior AI & ML Engineer with a strong foundation in machine learning fundamentals and hands-on experience with modern generative AI and Large Language Models (LLMs). You will work on cutting-edge AI functionality across a flagship cybersecurity platform, building scalable, performant systems that harness the power of data, ML models, and infrastructure.

Key Responsibilities:

• Design, develop, and deploy production-grade ML/AI features — from data prep and model training to inference APIs and monitoring.
• Integrate and scale LLMs & generative AI within product workflows, including fine-tuning, prompt engineering, RAG (retrieval-augmented generation), and agentic systems.
• Collaborate with product, backend, and frontend teams to deliver impactful AI-driven experiences.
• Take ownership of features by monitoring their functionality and effectiveness after deployment (observability).

Technical Requirements:

• Proven professional experience as an ML/AI Engineer.
• Expert proficiency in Python (for ML development) and JavaScript/TypeScript (for production integration).
• Deep understanding of ML/DL frameworks such as PyTorch and scikit-learn.
• Hands-on experience with state-of-the-art foundation models, embeddings, and RAG.
• Strong knowledge of cloud computing, microservices, API design, and event-driven architectures.
• Experience with Jupyter notebooks for data exploration and model iteration.

About You:

• You are driven, empathetic, and thrive in environments with high autonomy.
• You have a customer-centric mindset and care deeply about outcomes.
• You are comfortable with technical trade-offs, moving quickly while building secure and scalable solutions.

• Flexibility: Fully remote working arrangements (in similar time zones) or access to offices in London and Barcelona.
• Growth: A monthly budget for coaching and self-improvement (courses, conferences, workshops).
• Well-being: Comprehensive Health Insurance for you and your family, gym membership (Wellhub), and 25 days of vacation + public holidays.
• Family Support: Enhanced Maternity/Paternity leave.
• Culture: One volunteer day per year and a "day off" on your birthday.
