The Software Engineer II Role.

Reality Defender is looking for a Software Engineer II to help build and support our Microsoft Teams integration, with a particular focus on the Teams bot and underlying real-time audio/video media functionality.

This is a hands-on software engineering role for someone with strong .NET/C# experience who enjoys working on integrations, real-time systems, and production applications.

The ideal candidate will have experience with Microsoft Teams, bots, meeting applications, or real-time media streaming. However, direct Teams experience is not required if you have a strong .NET background and relevant experience building real-time audio/video, communications, or similar applications.

You’ll work closely with engineering, product, and AI teams to build secure, scalable, and reliable integrations that bring Reality Defender’s detection capabilities directly into enterprise communication workflows.

Responsibilities

• Design, build, and maintain the Microsoft Teams bot and related applications using .NET and C#.

• Develop the underlying real-time audio/video and media-streaming functionality supporting the Teams integration.

• Build and maintain backend services, APIs, and integrations that connect Microsoft Teams with Reality Defender’s platform.

• Work with Microsoft Teams APIs, Microsoft Graph, and related Microsoft technologies.

• Design and implement scalable services for real-time communications and media workflows.

• Integrate third-party services and APIs into production applications.

• Troubleshoot production issues, identify root causes, and implement long-term solutions.

• Improve the performance, reliability, scalability, and observability of integration services.

• Write automated tests and contribute to CI/CD and engineering best practices.

• Participate in architecture discussions, design reviews, and code reviews.

• Collaborate with Product and other engineering teams to translate requirements into scalable technical solutions.

• Take ownership of projects from design through development, testing, deployment, and ongoing improvement.

• Help shape the future of Reality Defender’s enterprise integrations and real-time detection capabilities.

Who you are.

• 3+ years of professional software engineering experience.

• Strong professional experience developing production applications with .NET and C#.

• Experience working in Windows and Visual Studio environments.

• Strong understanding of .NET frameworks, libraries, and development patterns.

• Experience designing, building, and consuming REST APIs.

• Experience building production software with a focus on reliability, performance, and maintainability.

• Experience with real-time audio/video, media streaming, communications, or similar technologies.

• Experience building bots, integrations, meeting applications, or other real-time applications is highly relevant.

• Strong debugging, troubleshooting, and problem-solving skills.

• Experience writing automated tests and working with modern software development practices.

• Ability to work independently while collaborating effectively with engineering and product teams.

• Strong written and verbal communication skills.

Nice to Have

• Highly Relevant Experience

  We’re particularly interested in candidates with experience in:

  • Microsoft Teams applications or bots

  • Microsoft Graph

  • .NET / C#

  • Windows and Visual Studio

  • Real-time audio/video

  • WebRTC or other real-time communications technologies

  • Meeting or collaboration applications

  • Note-taking or meeting-assistant applications

  • Voice/video applications

  • Enterprise integrations

  • Distributed or event-driven systems

  AI/ML experience is a plus, but not a requirement. The primary focus of this role is the engineering behind the Teams bot and real-time media functionality.

  Nice to Have

  • Experience with the Microsoft Teams Bot Framework or Teams SDKs.

  • Experience with Microsoft Graph APIs and Microsoft 365 integrations.

  • Experience with Azure or another major cloud platform.

  • Familiarity with WebRTC, RTP, SIP, VoIP, or related real-time communications technologies.

  • Experience with audio/video processing or media pipelines.

  • Experience with messaging systems or event-driven architectures.
