Johannesburg: Senior Full Stack Developer posted by iOCO Digital Pty Lty

About the Role

We are looking for a highly skilled Senior Full Stack Developer with strong full-stack experience and exposure to modern AI/agent build & integration platforms to join our team. In this role, you will play a key part in designing, developing, and delivering modern web applications using modern object-oriented backend technologies, cloud-based AI/agent platforms and developer acceleration tooling.

Key Responsibilities

• Development & Architecture:
• Design and develop RESTful APIs using modern object-oriented backend languages and frameworks (e.g., Java with Spring Boot, Python, Go, Rust)
• Build interactive web user interfaces using Angular
• Translate business requirements into scalable technical solutions
• Design and implement backend services as independently deployable microservices
• Implement clean architecture, CQRS, SOLID principles, and best practices
• Ensure high performance, responsiveness, and security
• Build and embed agent-enabled capabilities into solutions using appropriate platforms and services (e.g., Copilot Studio, Azure AI Foundry, Amazon Bedrock, Gemini) where applicable
• Apply engineering guardrails when using AI-assisted development tooling (e.g., Claude Code, BMAD) to ensure code quality, security, and reviewability

• Technical Leadership:
• Provide technical guidance and mentorship to developers
• Conduct code reviews and enforce coding standards
• Contribute to architecture decisions and technology selection
• Identify and address technical debt
• Contribute to selecting and standardising tooling patterns for agent build/integration (e.g., Copilot Studio/Azure AI Foundry/Bedrock) and AI-assisted engineering (e.g., BMAD/Claude Code), aligned to delivery constraints

• Integration & Data:
• Integrate with third-party services and internal systems
• Design and integrate data storage solutions appropriate to the selected backend technology stack
• Integrate agent-enabled services with enterprise systems and data sources, including secure access patterns, auditing, and operational controls

• DevOps & Quality:
• Collaborate on CI/CD pipelines and automated deployments
• Write unit, integration, and end-to-end tests
• Monitor and troubleshoot production issues
• Participate in agile ceremonies and planning
• Ensure AI/agent-related components are production-ready (configuration, secrets, logging/monitoring hooks, and safe rollout practices) and align with engineering standards when AI-assisted tools are used

Requirements

• Core Technical Skills:
• 5+ years experience building backend services using one or more modern object-oriented languages such as Java (Spring Boot), Python, Go, or Rust
• Strong experience designing and implementing RESTful APIs in a microservices-based architecture
• Solid understanding of REST, HTTP, and API design
• Experience with distributed systems concepts such as service boundaries, inter-service communication, and fault tolerance
• Experience or practical exposure to building/embedding agent-enabled capabilities using platforms such as Copilot Studio, Azure AI Foundry, Amazon Bedrock, or Gemini (or equivalent)
• Experience using AI-assisted engineering tools responsibly (e.g., Claude Code, BMAD or equivalent) with strong emphasis on code review, testing, and secure coding

• Front-End:
• Experience with Angular for web application development
• Component-based UI development (Blazor or equivalent)
• HTML, CSS, and modern UI practices

• Cloud & DevOps:
• Experience with Azure (App Services, Functions, Storage, etc.) or similar cloud
• CI/CD experience (Azure DevOps, GitHub Actions, or similar)
• Containerization (Docker) is advantageous
• Familiarity with integrating cloud AI/agent services into application delivery pipelines (e.g., Azure AI Foundry/Amazon Bedrock) and managing configuration/secrets appropriately

• Engineering Practices:
• Strong knowledge of SOLID principles
• Design patterns
• Secure coding practices
• Performance optimization
• Demonstrated discipline applying engineering standards when AI-assisted tools are used (reviewability, traceability of changes, testing coverage, and secure-by-design practices)

Soft Skills

• Excellent problem-solving and analytical skills
• Strong communication and stakeholder engagement
• Ability to work independently and lead initiatives
• Mentoring mindset and collaborative approach

Personal Attributes:

• Excellent verbal and written communication skills, with the ability to present complex ideas clearly.
• Strong analytical and problem-solving skills.
• Comfortable working under pressure and meeting established business objectives.
• Collaborative mindset with the ability to work effectively across cross-functional teams.
• Empathy for stakeholders and a user-centric approach to solution design.

Nice to Have

• Experience with:
• Microservices-based system design and implementation
• Domain-Driven Design (DDD)
• Automated testing frameworks (xUnit, NUnit, Playwright)
• Observability tools (Application Insights, OpenTelemetry)
• Hands-on experience delivering solutions with agent-build platforms (e.g.,
