Job description

We are hiring a Full Stack Engineer to design and deliver complete, end-to-end features that power ADAPT from data models and APIs to responsive, intuitive interfaces. You will build and integrate seamless user experiences and robust backend services that make complex supply-chain operations simple, efficient, and reliable.

Your work will enable engineers, procurement teams, and suppliers to operate in real time building confidence and agility across the energy ecosystem.

Key Responsibilities

Frontend Development and Implementation

• Build scalable, maintainable frontend architectures using modular React components and efficient state management.
• Implement reusable design patterns aligned with best practices and clean-code principles.
• Collaborate with UX/UI designers to transform design concepts into pixel-perfect, functional experiences.

Backend Development and Architecture

• Design and implement stateless RESTful APIs to support data exchange and system interoperability.
• Architect and develop microservices-based solutions ensuring high availability, scalability, and maintainability.
• Design efficient database schemas, optimise queries, and ensure integrity for both SQL and NoSQL data stores.
• Implement robust authentication and authorisation mechanisms using OAuth 2.0 with Azure Active Directory.
• Deploy serverless applications leveraging cloud-native services for cost-effective scalability.

End-to-End Integration

• Develop full-stack features from database to user interface, ensuring seamless data flow and user experience.
• Integrate frontend applications with backend APIs, managing state and performance across the stack.
• Implement error handling, data validation, and strong consistency between frontend and backend systems.
• Ensure alignment between API contracts, data models, and functional requirements.

Code Management and Quality

• Use Git and version-control best practices to manage code across distributed teams.
• Implement and maintain CI/CD pipelines for efficient deployment of full-stack components.
• Write comprehensive technical documentation for code, APIs, and integration workflows.
• Participate in code reviews and foster a culture of quality and collaboration.

Problem Solving and Optimisation

• Debug and troubleshoot complex issues spanning multiple system layers.
• Conduct performance audits and implement optimisations from database operations to UI rendering.
• Identify and address security vulnerabilities at all application layers.
• Implement monitoring and logging to ensure performance, stability, and traceability.
• Stay informed about emerging technologies and evaluate adoption opportunities where relevant.

Collaboration and Communication

• Work closely with product managers, designers, and developers to define and deliver impactful solutions.
• Translate business and technical requirements into cohesive system designs.
• Contribute to agile processes, sprint planning, and cross-functional collaboration.

Required Qualifications

Experience

• Minimum of five years of professional experience in full-stack or combined frontend/backend development post-graduation.
• Demonstrated success delivering high-quality, production-grade full-stack solutions.
• Experience working in agile or scrum environments.
