Role Overview
As Lead Software Engineer, you’ll take technical ownership of teams building modern, AI-powered applications. You’ll be the engineering lead – setting direction on architecture and standards, guiding the team through complex challenges, and acting as the senior technical voice with clients.
This isn’t a management-only role. You’ll remain hands-on, contributing to design and development alongside your team, whilst also coaching and developing the engineers around you.
Key Responsibilities
- Lead teams designing, building, testing, and maintaining high-quality software applications
- Take technical ownership of products – including architecture, estimation, planning, and requirements
- Drive integration of AI and ML capabilities, including prompt engineering, model evaluation, and RAG pipelines
- Work with Microsoft Azure AI services (Azure OpenAI, Microsoft Foundry, Cognitive Services) or equivalent platforms
- Champion software development best practices – XP, TDD, CI/CD – including for ML/AI workloads
- Engage directly with clients, communicating technical concepts and trade-offs clearly to both technical and non-technical stakeholders
- Manage, coach, and develop junior team members, supporting their performance and career growth
- Contribute to knowledge sharing within the team and broader engineering community
What You’ll Need
Essential
- Strong expertise in Python or C#/.NET, with a track record of building scalable, secure, modern applications
- Proven experience leading engineering teams and taking technical ownership of software products end to end
- Hands-on experience with AI/ML-powered product development – model integration, prompt engineering, RAG, or evaluation pipelines
- Experience with Microsoft Azure AI services or equivalent cloud AI platforms
- Expertise across the full application stack – API design, data pipelines, and front-end integration
- Experience with CI/CD practices, including for ML/AI workloads (model versioning, experiment tracking, automated evaluation)
- A genuine commitment to developing people – coaching and mentoring junior engineers
Desirable
- Experience with the Microsoft agent ecosystem – Copilot Studio, Semantic Kernel, Microsoft 365 Agents SDK, or Agent Framework
- Knowledge of responsible AI practices – content filtering, PII handling, bias testing, and governance of autonomous agent actions
- Familiarity with vector databases, search indices, or multiple programming languages and storage technologies
Benefits & Package
- Salary negotiable – based on your experience, discussed openly at first conversation
- Fully flexible working arrangement – office attendance is entirely optional
- A genuine investment in your growth, with access to learning, development, and career progression opportunities
- Work on technically ambitious programmes with real-world impact
