We're looking for a Senior Software Engineer to join a high-performing technology team building scalable, cloud-native applications and AI-powered solutions within a fast-paced enterprise environment. You'll work as part of an agile engineering team responsible for designing, developing, and improving critical platforms used across a large global organisation. This is a hands-on engineering role where you'll contribute across architecture, development, optimisation, and operational excellence while helping shape the future direction of modern AI-enabled systems.

What you'll be doing

• Designing, developing, and maintaining secure, scalable backend applications using Java and Python.
• Building and optimising cloud-native services and distributed systems within AWS environments.
• Developing intelligent search and AI-driven workflows, including semantic search and large language model integrations.
• Collaborating with engineers, product teams, and stakeholders to deliver robust technical solutions.
• Contributing to architectural decisions, engineering standards, and best practices across the software development lifecycle.
• Troubleshooting and resolving complex technical challenges across multiple systems and technologies.
• Mentoring engineers and promoting a collaborative, inclusive engineering culture.
• Evaluating and introducing emerging technologies where they can add measurable business value.

What we're looking for

• Strong commercial experience developing applications in Java and/or Python.
• Experience building and deploying cloud-native applications, ideally within AWS.
• Solid understanding of software engineering principles, system design, testing, and operational best practices.
• Experience working with scalable distributed systems and APIs.
• Knowledge of AI/ML technologies and modern intelligent application patterns.
• Ability to work independently and take ownership of technical delivery from concept through to production.
• Strong problem-solving skills with the ability to navigate complex technical environments.

Nice to have

• Experience working with semantic search, vector databases, or retrieval-augmented generation (RAG) architectures.
• Exposure to large language models and AI platforms.
• Background working within large-scale enterprise or highly regulated environments.
• Degree in Computer Science, Engineering, Mathematics, or a related technical discipline.
