Senior Java Software Engineer

🚀 We’re Hiring: Senior Java & AI/LLM/RAG Engineer (100% Remote, UK)

Location: Remote (Must be resident and legally authorized to work in the UK)

Type: Full-time

Stack Focus: Java 17+, Spring AI, LLMs, Deep Java Library, RAG Architecture, AWS cloud

Are you a seasoned Java engineer who has crossed the bridge into the world of Artificial Intelligence? Do you know how to take large language models (LLMs) and turn them into highly secure, production-grade, context-aware enterprise applications using Retrieval-Augmented Generation (RAG)?

If you want to sit at the intersection of robust backend engineering and cutting-edge generative AI, we have a seat for you.

🎯 About the Role

We are scaling our core platforms and embedding intelligence into every layer of our ecosystem. We are looking for a Senior Java & AI Engineer who can bridge the gap between traditional, high-performance enterprise Java development and modern AI/LLM integration.

You won't just be calling basic APIs; you will be designing intelligent agents, optimizing vector search embeddings, and building scalable RAG pipelines that process enterprise data securely and efficiently.

💼 What You’ll Do

• AI Integration & RAG Architecture: Design, build, and optimize RAG pipelines and LLM-powered applications using Java frameworks like Spring AI.
• Backend Engineering: Develop and maintain high-throughput, low-latency microservices using Java (17+) and Spring Boot.
• LLM Optimization: Implement prompt engineering best practices, guardrails, and caching mechanisms to optimize LLM performance, token usage, and accuracy.
• Cloud & DevOps: Deploy and scale AI workloads on cloud infrastructure (AWS/GCP), utilizing Docker, Kubernetes, and modern CI/CD pipelines.

🛠️ What We’re Looking For

• Strong Java Core: 5+ years of commercial software development experience with Java and the Spring ecosystem.
• Hands-on AI/LLM Experience: Proven experience building applications that interact with foundational models (OpenAI, Claude, Llama) and implementing RAG architectures.
• Vector Search Proficiency: Deep understanding of embeddings, tokenization, semantic search, and working with vector databases.
• Engineering Best Practices: Strong knowledge of data structures, design patterns, microservices, and writing clean, testable code.
• Location: Fully based in the UK with excellent asynchronous communication skills for a 100% remote team environment.

✨ What’s in It for You?

• 100% Remote Flexibility: Work from anywhere in the UK with no mandatory office days.
• Cutting-Edge Tech: Skip the legacy maintenance and work directly on high-impact generative AI and automation initiatives.
• Competitive Compensation: Attractive base salary, performance bonuses, and equity options.
• Top-Tier Perks: Private medical insurance (PMI), enhanced workplace pension, home-office tech budget, and an annual learning/conference stipend for AI certifications.
