Job description
Company Description
 
At Miravoice, we’re building the platform to capture conversations at scale. At its core is an AI voice agent for pollsters and market researchers to conduct natural sounding surveys using AI. Our value proposition is simple: we get our customers more data, faster, for less. And our vision is to grow the GDP of the voice economy and make precision data collection truly effortless.
 
Team
Our team is deeply technical and built for this problem. We're former engineers, tech product managers, and ML researchers with deep expertise in voice AI, SaaS, and survey methodology, including published research. We've studied CS & AI at Stanford, Yale, & UCLA, and led large teams at Google, Apple, VMware, and McKinsey. Miravoice is backed by an all-star roster of top tech investors, including Unusual Ventures, Neo, 25madison Ventures, and angel investments from industry leaders at Google, Ramp, Atlassian, and PubMatic.
 
Role Description
As a Founding Engineer, you’ll help shape both our product and our company. You’ll work closely with the founders to design architecture, ship features, and define the product vision. You’ll have real ownership, and your decisions will have lasting impact on our technical and product direction. Beyond just programming, you’ll have the opportunity to co-author and publish novel research, interact with customers directly, and travel to conferences if you so desire.

Why it’s interesting:

  • Domain: You'll get exposure to the bleeding edge of voice AI. We’re building next-generation systems that can precisely handle complex hour-long conversations, with voices that sound genuinely human. You’ll work to improve AI conversation quality, scale our platform’s infrastructure to handle tens of millions of calls, and build out critical user flows for our customer-facing product console.
    •  
  • Strong customer pipeline: we’re already working with top polling and market-research firms and have made over 100,000 calls, with many more in the funnel.
    •  
  • Our founding team values builders above all, because we’re all builders at heart: We’re three deeply technical co-founders who have published papers in top journals, shipped software to millions of users, and led large teams at iconic technology companies like Apple, Google, and VMware. You'll get to grow alongside a rockstar team with product acumen and strong technical chops.
    •  
  • We’re making waves: we’ve been featured in a16z’s Future of Market Research, Greylock’s AI-Native User Research, and Google’s Gradient AI Fund theses on the space (under our old product name, Surveybot AI).
    •  
  • Research-focus: We’ve published and presented at top conferences like AAPOR, NLPOR@COLM, and MAPOR. Our founding engineers co-author publications and attend conferences alongside the founders and our customers.

What We’re Looking For

  • We're looking for strong generalist founding software engineers who are driven, independent, and want to push the boundaries of Voice AI at a breakneck pace. The skill we care about the most is the ability to learn quickly. Other characteristics that stand out:
    •  
  • Strong technical skills in backend, distributed systems, or AI/ML (bonus if you’ve worked with speech/voice systems)
  • Product-minded: you care deeply about user experience and design
  • Strong communication and collaboration skills
  • Experience building and shipping products in a startup or fast-paced environment
  • Excitement about joining an early-stage company and wearing many hats
  • Preferred but not required: Bachelors Degree or higher in Computer Science or Statistics

Other considerations:

  • Location: this role is in-person in the San Francisco Bay Area
  • Benefits: we offer competitive salaries, health insurance, dental & vision plans, a 401k match, and generous equity packages
