Digital ads drive over 100 billion phone calls to U.S. businesses every year… Surprisingly, the marketers who paid for those ads typically have zero insight into these customer interactions and conversions. As the market leader in call analytics and customer experience optimization, DialogTech provides data-driven marketers with an end-to-end call attribution and analytics platform. This enterprise-class solution delivers visibility and control over every conversation, so companies can optimize lead generation, map the full path to conversion, and increase sales conversions.
 

Thanks to smartphones, consumers are calling businesses to engage in conversations at record rates throughout every step of the customer journey, and at DialogTech we are changing the world of voice communications for our customers. We enable our customers to better attribute, route, personalize, and handle their voice interactions at each stage of the marketing and sales process.
 

The team you’d join:
 

Our Software Engineering, Voice team is pushing the boundaries of web and VoIP technology to provide VoIP infrastructure and online communication services at scale. We process millions of calls per month, across our own datacenters and cloud infrastructure. From detecting and blocking spam calls with machine learning, building out our API, to helping our customers make sense of the massive amounts of data generated by their phone calls. We have no shortage of challenges and opportunities.
 

As an Associate Software Engineer focused on real-time communications, you will spend much of your time developing powerful voice communications apps using the open source Adhearsion Ruby application framework. You will build dynamic voice applications that enable our customers to control the user experience of voice communications in real-time using our webhook API. Your solutions will often be multi-threaded and will scale to handle thousands of concurrent conversations.
 

While building scalable Ruby applications, you will also develop valuable experience with real-time voice communications, as you learn of the underlying VoIP protocols that your high-level Ruby business logic controls. You will gain experience with the open source Asterisk telephony PBX that runs under Adhearsion. And you will also learn how to analyze the underlying VoIP network traffic that you control to ensure that it is behaving as you desire. This is an opportunity to become a true full stack developer!
 

You will also learn and help develop the machine learning technology behind DialogTech's SpamSentry™ service, which intelligently detects and block / "spam" calls, reducing the frustration and costliness associated with those pesky robo-dialing telemarketing phone calls.

• Knowledge of object-oriented programming and design patterns
• Professional experience working as part of a team committed to hitting deadlines
• Experience with a modern VCS (git, hg, bazaar, svn, etc.)

The nice-to-haves: 
 

• A link in your application to a coding project that you participated in. This may be on GitHub, BitBucket or elsewhere.
• Familiarity with the concepts required to construct multi-threaded code
• Comfort in working in a Linux environment with various CLI tools
