Job description

We are looking for a Solution Designer, IT (Fullstack – AI Ops & Support) to develop, enhance, integrate and support enterprise applications while providing technical operations support for enterprise AI platforms and AI-enabled applications. This hybrid Development + AI Operations role combines hands-on full stack development with troubleshooting across application, API, database, integration, cloud and AI layers, including Generative AI and Agentic AI solutions.

Make An Impact By

• Full Stack Application Development
• Design, develop, test, deploy and support enterprise web applications and digital solutions.
• Build and maintain front-end, back-end and integration components using modern development frameworks and engineering practices.
• Deliver committed development work within agreed sprint and release timelines while maintaining code quality, security and supportability.
• Use approved source control and CI/CD processes for production deployments where technically applicable.
• AI Application Operations & Technical Support
• Provide technical support for enterprise AI platforms and AI-enabled applications, investigating user issues, performance problems, AI failures, RAG issues and workflow failures.
• Troubleshoot production issues across application, API, database, integration, cloud and AI layers and progress incidents within agreed service levels.
• Diagnose issues involving prompts, context, knowledge sources, models, integrations and application behaviour, escalating only when deeper engineering or vendor support is required.
• Support timely restoration of service for high-priority AI incidents and contribute evidence-based troubleshooting during major incidents.
• Generative AI, LLM & Agentic AI Support
• Apply practical knowledge of Generative AI, Large Language Models (LLMs), prompt engineering, context and token management, Retrieval-Augmented Generation (RAG), embeddings, vector search and model APIs.
• Investigate retrieval quality, document ingestion and indexing, embeddings and knowledge-source issues.
• Diagnose model errors, timeouts, token-limit, rate-limit and content-filter issues.
• Support Agentic AI solutions by diagnosing failed agent executions, tool or API invocation failures, permission or authentication issues, and using available traces and logs to identify root causes.
• API, Integration & Platform Support
• Develop and support integrations between AI applications and enterprise systems.
• Troubleshoot authentication, authorisation, payload, connectivity, timeout and downstream application issues.
• Monitor critical integrations and support reliable API service availability.
• Ensure APIs and integrations follow approved authentication, authorisation and security requirements.
• Incident, Problem Management & Continuous Improvement
• Provide Level 2 / Level 3 technical support for enterprise applications and AI platforms.
• Perform root cause analysis for major or severe incidents within agreed timelines and document corrective and preventive actions.
• Reduce repeated incidents by addressing underlying technical causes rather than relying on recurring workarounds.
• Collaborate with IT management, business stakeholders, vendors and delivery teams to translate business requirements into effective technology solutions and uphold established development standards.
• Maintain broad technical knowledge across the systems portfolio and manage multiple concurrent workstreams effectively.

Skills For Success

• Degree in Computer Science, Information Technology, Software Engineering or equivalent professional experience.
• More than 3 years of software development experience.
• Strong hands-on experience across several front-end technologies such as React/ReactJS, TypeScript, JavaScript, HTML5, CSS and modern web development frameworks.
• Back-end development experience with technologies such as .NET/.NET Core/C#, Node.js and Python.
• API and integration experience covering REST APIs, JSON, OAuth 2.0, JWT, API authentication and authorisation, webhooks and API testing tools such as Postman.
• Database experience with Microsoft SQL Server, PostgreSQL, MySQL, Azure Cosmos DB or equivalent technologies.
• Cloud and DevOps experience with Microsoft Azure and/or AWS, Git, CI/CD, Azure DevOps or GitHub, Docker and containers.
• Practical knowledge of Generative AI, LLMs, RAG, prompt engineering, Agentic AI, AI agents, AI application troubleshooting and LLM APIs.
• Experience with one or more of Azure OpenAI, OpenAI APIs, Azure AI Foundry, Microsoft Copilot Studio, Semantic Kernel, LangChain, LangGraph, AutoGen or MCP is an advantage.
• Experience with monitoring or logging platforms such as Azure Monitor, Application Insights, Elastic/ELK, Splunk, Grafana, Dynatrace, Datadog or OpenTelemetry is an advantage.
• Strong communication, collaboration, analytical problem-solving, ownership and time-management skills.
