This role offers the opportunity to work with .NET (Core and Framework), React, SQL Server, and cloud services on Azure or AWS. Experience with TFS/ADO and Gitlab along with Infrastructure as Code (IaC) is important as we continue to build out our cloud environments.

• Develop and maintain backend systems using C#/.NET.
• Build modern front-end interfaces using React or similar frameworks.
• Work with SQL Server to write and optimize queries.
• Contribute to cloud-based solutions on Azure or AWS, including serverless components.
• Define and manage infrastructure using Infrastructure as Code tools (e.g., ARM, Bicep, Terraform, CloudFormation).
• Participate in system design discussions and provide technical guidance across the team.
• Support the ongoing migration of applications and services to the cloud.
• Collaborate closely with developers, DevOps, and product stakeholders.

What We’re Looking For

• Strong knowledge of .NET (C#) and backend development.
• Front-end experience with React or a similar JavaScript framework.
• Solid experience with SQL Server and query optimization.
• Cloud development experience with Azure or AWS.
• Proficiency in Infrastructure as Code (IaC).
• Good understanding of modern software practices and deployment workflows.
• Strong communication skills and a collaborative approach.

Nice to Have

• Experience with serverless technologies like Azure Functions or AWS Lambda.
• Exposure to containerization (Docker, Kubernetes).
• Any Cloud certifications or Dev Ops.

What We Offer

• A collaborative environment with room to influence technical decisions.
• Opportunities to grow as we modernize our platform.
• A team that values clean, maintainable solutions over quick fixes.
