You'll be part of a well-established delivery team, collaborating closely with technical leads, testers, and stakeholders to deliver robust solutions within a structured governance framework.

What you'll be doing:

• Estimating effort and resources for development requirements as needed.
• Developing new features and improving existing functionality using best practices and coding standards.
• Creating clear functional design specifications and user stories to guide development.

• Communicating technical challenges or potential risks promptly to team leads to enable proactive resolution.
• Engaging with project stakeholders to align development efforts with business needs.
• Keeping development and planning tools up to date with task progress and status.

The ideal candidate will have excellent communication skills and a strong analytical approach. Experience working in structured, standards-driven environments is essential, along with the ability to collaborate effectively across technical and non-technical teams.

• Strong analytical and problem-solving capabilities.
• Proven experience in standards-based software development.
• Excellent interpersonal and communication skills.
• Comfortable working alongside application developers, testers, and team leads.
• Familiarity with project delivery methodologies including Agile, Waterfall, and hybrid approaches.
