It offers a full-featured VoIP phone with a real number and texting capabilities, all over Wi-Fi or 3G/4G networks.

Working for Line2 is going to put your creativity and aspirations to the test and you will come out the better for it.  Our success is a result of the emerging changes in the mobile business world, including the boom in smartphones, the shift to IP based communications, and the continuing explosion of cloud-based services.

Line2 is looking for a Windows Server developer to join our diverse organization in downtown San Francisco.  You will work with an experienced team building out scalable, easy to maintain systems that support our front end telecommunications technology.  Challenges include intuitive Web Service API design, non-trivial subscription and usage based billing, proper database design and replacing legacy systems with more scalable componentized code.

• Build out new features while evolving the existing user experience and interfaces for our clients.
• Develop in a cross computer, multi-tiered application environment using Web Services.
• Bring a strong desire to properly design the systems you build.
• Collaborate with Product owners, QA and other Developers to create robust and solid software.
• Participate in Agile software projects, delivering running code as the gauge of your productivity.

• Software development experience of 3+ years on Windows Servers.
• Specific experience using C# and T-SQL, along with the technologies used to create and consume Web Services (MVC / WCF / Web API) with both SOAP and REST type interfaces.
• Knowledge of past Microsoft technologies, like .Net Remoting, COM and ASP Classic will be useful in replacing the use of those technologies.  Having used C++ is beneficial but not required.
• Experience working on large scale, real-time backend systems that support customer facing applications.
• Comfortable interacting with technical and non-technical team members.
• Any background experience with Telephony and Public Clouds (Azure, AWS, etc.) is a plus.
• Education in Computer Science or comparable work experience.
