Job Description

We’re looking for a Junior Software Developer to join our growing team. This role is ideal for someone with a solid foundation in JavaScript who is eager to learn, contribute, and grow in a collaborative environment.

While our future is focused on modern web technologies, we currently maintain a legacy low‑code platform (Infinite Blue) that supports critical business processes. You’ll play a key role in helping us sustain this platform during our migration to a new, modern stack, giving you exposure to both legacy systems and cutting‑edge development practices.

Your contribution

• Maintain and enhance the current Infinite Blue low‑code platform.
• Provide support to existing customers, ensuring smooth operation of business‑critical applications.
• Develop new strategic application using React while utilising the current design system for components.
• Participate actively in agile ceremonies (stand‑ups, sprint planning, retrospectives).
• Learn and adapt quickly to new tools, frameworks, and processes.
• Help resolve production defects, issues, and queries in a timely manner.
• Demonstrate a strong willingness to learn and grow within the team.

What Makes You Stand Out

Requirements

• Knowledge of JavaScript (ES6) and React.
• Understanding of web fundamentals (HTML, CSS, REST APIs).
• Willingness to work with and learn a low‑code platform (Infinite Blue).
• Problem‑solving mindset and eagerness to learn new tools and frameworks.
• Good communication skills and ability to work in a team‑oriented environment.
• Familiarity with Git or other version control systems.

Desirable

• Experience with C# or other back‑end languages.
• Exposure to cloud platforms such as AWS or Azure.
• Familiarity with Agile methodologies (Scrum/Kanban).
• Interest in CI/CD practices and DevOps tooling.
• Experience using JIRA and Confluence for project management and documentation.
• Curiosity about leveraging AI tools for software development.

What We Offer

A competitive salary, 25 days of annual leave, and extra day off to celebrate your birthday! Pension contributions up to 5%.
