About Dialpad

Work Beautifully

Dialpad is the leading Ai-Powered Customer Intelligence Platform that is transforming how the world works together. Based on 4 billion minutes of analyzed voice and meetings data and growing, we have designed one, beautiful workspace that seamlessly combines the most advanced Ai Contact Center, Ai Sales, Ai Voice, and Ai Meetings with Ai Messaging. More than 30,000 innovative brands and millions of people use Dialpad to unlock productivity, collaboration, and customer satisfaction with real-time Ai insights. With initial funding and leadership from Google and leading venture capitalists such as ICONIQ and Andreessen Horowitz, Dialpad has over $200M in ARR and is one of the fastest growing Ai companies in the world.

Dialpad’s Telephony Core team owns the real-time media platform upon which our business communications are built. Our mission is to provide the best customer experience possible across a vast array of clients, networks and environments. From overcoming network limitations and background noise, to ensuring the media we handle is of the best possible quality, we set a high bar to make Dialpad a world-leading communication platform.

What we need

The world of real-time communications is a particularly challenging space. Dialpad is looking for talented DSP engineers who enjoy building high-performance signal processing and AI-based solutions at the forefront of our industry. We are less concerned with years in industry or particular technologies and more interested in knowledge, passion, and perseverance.

We need engineers who solve complex business problems in a fast-paced startup, and use their autonomy to drive innovation. We need leaders who are passionate about the quality and efficiency of a service used by millions of daily users. We need pioneers dedicated to finding new solutions and ways of making existing ones even better.

This opportunity can be based in US, not specifically in SF.


  • Develop cutting edge signal processing algorithms to enhance the quality of every Dialpad call and meeting.
  • Understand and improve our current voice enhancement system.
  • Research, code, test, document and deploy new media enhancement solutions.
  • Drive the technical roadmap with the latest industry best practices and your own innovative ideas.
  • Collaborate with team members and stakeholders to integrate solutions into browsers, client and server applications and test tools.
  • Be at the forefront of Dialpad’s venture into real-time AI audio/video enhancement.
  • Improve our shared engineering standards and processes.
  • Learn from and teach other great engineers.
