We are seeking a Junior .NET Developer to support a large-scale modernization initiative focused on replatforming legacy applications to .NET Core. This role is ideal for a developer who has a solid foundation in .NET Core, enjoys collaborative team environments, and is eager to grow within a structured but evolving organization.

You’ll be joining a small team of developers working on a mix of modernization and new development efforts. Success in this role is driven less by having every answer on day one and more by curiosity, adaptability, and a strong team‑first mindset.

What You’ll Be Doing

• Assist with replatforming and modernizing legacy .NET applications into .NET Core
• Support backend and frontend development efforts as part of a broader application modernization strategy
• Collaborate closely with teammates and stakeholders in an Agile-style environment
• Learn and adapt to established processes typical of large or public‑sector organizations
• Contribute to AWS‑backed applications and services, with mentorship and guidance
• Participate in code reviews, testing, and iterative improvements

What We’re Looking For

• Hands‑on experience with .NET Core and .NET
• Exposure to application development in structured environments
• Familiarity with Agile concepts or a willingness to learn them
• Strong communication skills and a collaborative working style
• Openness to working onsite two to three days per week
• Comfort navigating legacy systems while learning modern approaches

Nice to Have

• Introductory experience with AWS
• Background in public sector or large enterprise environments
• Exposure to both frontend and backend development

Why This Role

This is a strong growth opportunity for developers who want real‑world experience modernizing critical systems. You’ll gain exposure to cloud technologies, modernization strategies, and large‑scale applications while working with a team that values learning, patience, and collaboration.
