Job description

Join a company that’s leading the way in AI and automation consulting. Our portfolio spans 10+ top technologies across business applications, data, process, cloud, and AI. At Bits In Glass, you’ll do meaningful work with a supportive, driven team that loves to collaborate and celebrate wins together. Whether you’re coding, consulting or bringing bold ideas to the table, you’ll tackle real business challenges, grow your skills, and make a BIG impact. 

Our growing team has earned global recognition as a Great Place to Work and received multiple industry partner awards—while keeping things fun and people-focused. If you’re looking to deepen your expertise and solve real-world problems, Bits In Glass could be the place for you. 


We’re hiring two Senior .NET Engineers to support a healthcare industry client on key software development initiatives. The roles will focus on building and enhancing integration solutions, maintaining and modernizing legacy systems, and implementing AI-driven security enhancements across web applications. We’re looking for engineers who are comfortable working across modern and legacy .NET environments and who actively use AI-assisted development tools as part of their daily workflow.

This position is ideal for someone who is systems-oriented, enjoys learning new tools and technologies, and can work effectively both independently and as part of a collaborative team.


Location: Remote (must overlap with 8:00 AM–5:00 PM MST business hours) 


Roles and responsibilities: 

  • Design, build, and maintain C# APIs and web applications, including work on both modern .NET and legacy ASP.NET Web Forms/MVC codebases.
  • Use AI-assisted development tools (e.g., Claude Code) as a core part of your engineering workflow, from implementation to code review.
  • Depending on assignment: contribute to system integration and legacy modernization efforts, or implement security monitoring features (e.g., sensitive-data access alerts) across dozens of production web applications.
  • Build and maintain automated regression test coverage for changes you ship.
  • Collaborate with client engineering teams on code reviews, CI/CD, and production releases.


Required skills and experience: 

  • Senior-level, full-stack .NET engineer with software architecture experience.
  • Strong hands-on experience with C# APIs and web application development, plus working knowledge of legacy ASP.NET Web Forms/MVC.
  • Recent, active experience using AI-assisted development tools (Claude Code or similar).
  • Experience with ASP.NET Core / recent .NET versions, CI/CD pipelines, and SQL Server or Oracle.
  • Comfortable writing or maintaining automated tests (e.g., Playwright) for regression coverage.
  • Strong written and verbal communication skills in English.
  • Able to work from a private, dedicated workspace with secure internet (client security requirement).


Nice to Have

  • Experience with Kafka, Change Data Capture (CDC) patterns, or event-driven architecture.
  • Background in healthcare or other highly regulated industries.
  • Experience modernizing legacy websites/applications.
  • Familiarity with front-end tooling such as HTML, CSS, JavaScript, and Bootstrap.
