SQCE - Senior Full-Stack Developer

We are seeking a highly skilled Senior Full-Stack Developer with deep expertise in React and strong experience building backend services and deploying applications to Microsoft Azure. This role will focus on building, deploying, and optimising scalable, high-performance web applications that handle large volumes of data and integrate AI-driven components. You will work closely with backend engineers, cloud specialists, and AI teams to deliver intelligent, production-ready applications at scale. You will be expected to contribute to system design and architecture decisions, not just implementation., * Design, build, and maintain scalable full-stack applications using React and modern JavaScript/TypeScript on the frontend, and Python on the backend.

• Participate in system design from the outset, defining service boundaries, data flows, and architectural trade-offs rather than being handed a spec to implement.
• Build front-end solutions that support high data throughput, performance optimisation, and responsiveness at scale.
• Design and implement clean, well-documented APIs and backend services that integrate with the frontend and downstream systems.
• Integrate front-end applications with AI-powered services, including LLM-based APIs and workflows and Agentic AI systems.
• Work with automation and orchestration services, particularly within Azure.
• Work with containerised environments such as Docker and contribute to cloud-native deployment pipelines.
• Support CI/CD processes and promote reliable, repeatable deployments.
• Collaborate on the deployment of applications to Azure, owning your deployments end to end.

• Extensive experience as a Senior Full-Stack Developer or similar role.
• Expert knowledge of React, including modern patterns, hooks, state management, and performance optimisation.
• Strong backend experience in Python, with a track record of building production-grade services. Candidates with a background in .NET or Java who are comfortable working in Python are equally welcome.
• Proven system design ability. You can drive architecture discussions, justify technical decisions, and translate complex requirements into scalable solutions.
• Proven experience deploying applications to Microsoft Azure.
• Experience integrating applications with APIs, microservices, and distributed systems.
• Familiarity with container technologies such as Docker and container-based deployment models.
• Experience working on applications that handle large datasets or high-traffic environments.
• Strong understanding of front-end performance, observability, and optimisation techniques.

Nice to Have

• Hands-on experience integrating with LLM APIs such as OpenAI, Azure OpenAI, or similar.
• Familiarity with agentic AI frameworks such as LangChain or LangGraph.
• Experience building or consuming RAG pipelines, including vector search and document retrieval patterns.
• Understanding of prompt engineering and how LLM-based systems behave in production.
• Exposure to Azure AI services, including Azure Cognitive Search or Azure Machine Learning.
• Experience working alongside data science or AI teams and translating their outputs into production-ready applications.
