🧭 Collaborating on architecture, roadmap decisions, and code quality
📊 Designing data pipelines to support AI workflows, including validation, transformation, and enrichment
☁️ Building and maintaining AWS based infrastructure using infrastructure as code
🚀 Supporting CI/CD pipelines for reliable deployment and testing
🔐 Working to high security and compliance standards, including ISO
27001

What I’m looking for
Essential experience
✅ Strong Python backend engineering experience, ideally 3+ years
✅ Hands on experience using LLMs or AI systems in a production environment
✅ Solid AWS knowledge and experience with infrastructure as code

✅ Experience with LLM integration frameworks

✅ Experience with containers, orchestration, and CI/CD pipelines
✅ Good understanding of database scaling, caching, and performance optimisation
✅ Strong software engineering fundamentals and clean coding practices

Nice to have
➕ Exposure to frontend frameworks such as React

➕ Familiarity with ISO
27001 or regulated environments
➕ A curious, customer focused mindset and genuine interest in AI innovation
