What is Sela?

Sela is revolutionizing phone sales with its cutting-edge AI phone agent that can engage in open-ended conversations more effectively than traditional call center agents. We leverage a unique architectural approach that allows for remarkable flexibility and responsiveness during phone interactions, ultimately leading to greater conversion rates. With a solid $6 million seed funding from a top venture capital firm, we're building a stellar engineering team to drive innovation and growth.

What will you do in this role?

This is an exciting opportunity to take on a high-growth, hands-on leadership role in a fast-paced environment. You will collaborate closely with the founding team to continuously rethink and redesign Sela's backend services as we scale to handle millions of calls daily. Additionally, you will play a crucial role in the hiring process and serve as a mentor and tech lead for junior engineers.

Why join us?
  • The technology is groundbreaking. You'll be at the forefront of applied AI, working on low-latency, real-time speech applications where every millisecond matters. Building lifelike, interactive agents presents an exhilarating challenge.
  • We have immense potential for growth. Approximately 2% of the U.S. workforce is in phone sales, representing a $250 billion market-our technology is set to transform this industry, providing substantial product-market fit.
  • You'll work directly with visionary founders. Nate is a seasoned entrepreneur and Y Combinator alumnus, and Vahe brings experience as a tech lead from Google and extensive knowledge in NLP.
Your responsibilities will include:
  • Designing and building scalable backend infrastructure for real-time communication.
  • Creating and maintaining a public API for Sela's partners.
  • Developing integrations with various 3rd party software like CRMs, Dialers, calendars, and custom APIs.
  • Collaborating with fellow backend engineers to enhance our real-time communication capabilities.

  • Working alongside the DevOps team to optimize deployment and scaling strategies.
  • Collaborating with frontend engineers to support the user-facing web application.
  • Working with machine learning engineers to enhance our proprietary AI features.
