Web Developer Co Op Jobs in Calgary, AB (NOW HIRING)

Role Profile | .NET, C#, SQL Server, Applications and Integrations
Term: 4 months | Full-time | Paid
Role Summary

The Application Developer Co-op Student works alongside our development team to build, enhance, and support the business applications, integrations, and databases used across the organization. Under the guidance of a senior developer, you will take on real project work - writing code that ships, helping troubleshoot live systems, and contributing to integrations that move data between our enterprise platforms. This is a hands-on role for a student who wants to leave the term with production experience in Microsoft technologies including .NET, C#, SQL Server, GitHub, and GitHub Copilot, plus a genuine understanding of how software gets delivered and supported in a corporate environment. No prior professional experience is expected - coursework, personal projects, and curiosity count.

What You'll Work On
Application Development
Write, test, and maintain features for business applications using .NET and C#, with code review and mentorship at every step.
Make enhancements and fixes to existing applications based on business requests.
Help build and maintain APIs, services, and backend components.
Investigate and resolve application defects, working up from smaller, well-scoped issues.
Use GitHub and GitHub Copilot day to day for source control, pull requests, code generation, testing, and documentation - and learn where these tools help and where they don't.
Write and update technical documentation for the work you deliver.
Follow our development standards, security practices, and change management processes.
Sit in on technical design discussions and code reviews to see how decisions get made.

Integration Development
Assist with integrations between enterprise applications, databases, cloud services, and third-party platforms.
Help build integrations using APIs, web services, middleware, and ETL tooling.
Support the development of data transformation and mapping logic between systems.
Help investigate integration failures and verify the fixes.
Participate in testing, deployment, and monitoring of integration solutions.
Learn how requirements move from a business conversation to a technical specification.

Application Support
Provide Tier 2 support for internally developed applications, escalating to senior team members as needed.
Help analyze application, integration, and database issues and reproduce reported problems.
Assist with monitoring application performance and system health.
Document solutions and troubleshooting steps so the next person finds them faster.

Continuous Improvement
Look for small automation opportunities that save the team or the business time.
Bring forward ideas - fresh perspective on our tools and practices is genuinely welcome.
Build familiarity with Microsoft development tools, platforms, and best practices.

What We're Looking For
Currently enrolled in a Computer Science, Software Development, Information Technology, or related post-secondary program, and returning to studies following the work term.
Foundational programming experience in C#, .NET, or a comparable object-oriented language, through coursework, personal projects, or a previous work term.
Working knowledge of relational databases and SQL - writing queries, understanding joins, reading a schema.
Familiarity with Git-based version control and collaborative development workflows.
Understanding of core software development concepts and the development lifecycle.
Strong analytical and problem-solving skills, and a willingness to dig into unfamiliar code.
Clear written and verbal communication - you'll be asking questions and explaining your work.
Ability to work both independently and as part of a team.
Good organizational and time-management habits, and comfort asking for help early rather than late.

Bonus Points For
Exposure to REST APIs - building or consuming them.
Any experience with ASP.NET Core or modern web application development.
Familiarity with Entity Framework.
Exposure to Microsoft Azure or other cloud platforms.
Experience with GitHub Actions or any CI/CD tooling.
Exposure to Power Platform (Power Apps, Power Automate, Power BI).
Curiosity about ERP, CRM, or field operations systems such as Dynamics 365 Business Central, Salesforce, or FieldFX.
A portfolio, personal project, or repository you're happy to walk us through.

What You'll Take Away
Production code shipped to a real user base, not a sandbox project set aside at term end.
Direct mentorship from senior developers, including regular code review and feedback.
Practical experience with the Microsoft stack - .NET, C#, SQL Server, Azure, and GitHub Copilot - as used in industry.
Exposure to the full delivery cycle: requirements, design, build, test, deploy, and support.
A clear view of how enterprise systems connect and where the hard problems actually live.
