This is a hands‐on role in a small, high‐performing team where curiosity, collaboration, and secure coding standards are essential. You'll help shape development best practice, mentor junior developers, and contribute to a culture of continuous improvement and technical excellence.

• Contribute to CI/CD pipelines and automated testing frameworks to ensure code quality and fast, safe deployment.
• Participate actively in agile ceremonies, sprint planning, and retrospectives to ensure delivery alignment and transparency.
• Work closely with cross‐functional teams (Product, BA, QA, Architecture) to translate requirements into actionable technical solutions.
• Conduct and participate in peer code reviews, promoting quality and consistency across the codebase.
• Mentor and support junior developers, providing guidance on coding techniques, tooling, and secure coding standards.
• Take ownership of software quality by writing clean, modular, and well‐documented code.
• Contribute to refinement and enforcement of team coding standards, testing practices, and development methodologies.
• Investigate and resolve complex issues, identifying root causes and delivering sustainable solutions.
• Stay current with emerging technologies, frameworks, and security practices relevant to modern web and API development.

• Proven experience as a software developer, ideally within agile product or digital transformation teams.
• Experience in Python and proficiency in React.
• Experience designing and integrating REST APIs, webhooks, and working with data securely across systems.
• Solid understanding of secure coding principles and experience implementing them within development pipelines.
• Experience working with CI/CD pipelines and modern DevOps tools (GitHub Actions, Azure DevOps, or similar).
• Familiarity with containerisation and cloud platforms (AWS or Azure).
• Strong analytical and problem‐solving skills; able to simplify complexity and take initiative.
• Collaborative team player who enjoys working in an agile, fast‐paced environment.
• A natural curiosity for learning and improving both personal and team capabilities.
