Experience using Azure DevOps or comparable tools for work management, source control, build, testing, and deployment pipelines.
Experience conducting design walkthroughs, code reviews, impact assessments, and technical troubleshooting.
Experience eliciting and documenting information from diverse business stakeholders, subject-matter experts, architects, and other IT professionals.
Experience providing implementation, conversion, migration, and post-implementation support for complex applications.

General Skills / Duties:

Translate approved technical system specifications into working, tested, secure, and maintainable enterprise platform applications.
Develop detailed programming specifications and design, write, generate, compile, debug, document, maintain, and unit test application code.

Participate in design walkthroughs, impact assessments, code reviews, estimation, backlog refinement, sprint planning, release planning, and technical decision-making.
Review, analyse, and modify build, configuration, product-installation, and deployment scripts, including coding, testing, and debugging.
Resolve and troubleshoot technical problems arising during development, implementation, conversion, migration, deployment, and operation.
Collaborate with business analysts, architects, UX designers, testers, DevOps engineers, security specialists, and other IT professionals throughout the software development lifecycle.
