We are looking for a Junior Software Engineer to join our Client team and take ownership of the internal tools and applications that support our Client organization’s operations.
As a Junior Software Engineer with 3+ years of experience, you will be a key technical authority within the team, taking ownership of the full lifecycle of internal applications, from architecture and development through to maintenance, optimization, and continuous improvement. You will work across a broad technology stack (front-end, back-end, scripting, and databases) and act as a technical reference for the team. You will translate business needs into reliable software, drive engineering standards, and mentor junior colleagues.
Professional Skills:
• Full-stack development: ASPX/ASP.NET, Java/Tomcat, and PHP/MySQL.
• Strong Java development skills: REST APIs, servlet-based architecture, Tomcat lifecycle management.
• VB.NET for enterprise Windows applications: WinForms, data binding, system integration.
• Scripting and automation: Python, VBA, and PowerShell across Microsoft and enterprise environments.
• Advanced SQL skills on Oracle (PL/SQL, stored procedures) and MS SQL Server (T-SQL, SSMS, query optimisation).
• MySQL experience in web application contexts: schema design, query tuning, and application integration.
• Git version control: branching strategies, code review, and CI/CD integration.
• Agile practices: Scrum/Kanban, sprint planning, backlog refinement, iterative delivery.
• Atlassian suite: Jira for tracking, Confluence for documentation, Bitbucket for source control.
• Strong grasp of software engineering principles: clean code, SOLID, design patterns, and unit testing.
• Clear communicator with both technical teams and non-technical stakeholders.
• Proven ability to mentor engineers and raise team-wide code quality.
Tasks:
• Design, build, and maintain internal applications across the full stack.
• Own delivery end-to-end: from requirements and design through deployment and support.
• Develop and maintain database objects across Oracle, MS SQL Server, and MySQL.
• Write automation scripts in Python, PowerShell, and VBA to reduce manual effort.
• Analyze and refactor legacy applications (VB.NET, VBA, ASPX) for quality and performance.
• Work with stakeholders to turn business requirements into technical specifications.
• Lead code reviews and enforce development standards across the team.
• Troubleshoot complex issues across applications and databases, including root cause analysis.
• Maintain technical documentation in Confluence.
• Participate in Agile ceremonies and contribute to sprint planning and estimation.
Qualifications:
• Bachelor's or Master's in Computer Science, IT, Software Engineering, or related field.
• 3+ years of professional software engineering experience (must have).
• Proven expertise across: Java, Python, VB.NET, PHP, PowerShell, VBA, ASPX.
• Strong production experience with Oracle and/or MS SQL Server.
• Track record of delivering internal tools and enterprise applications.
• Professional certifications (Java, Microsoft, Oracle, or similar) are a plus.
