Founding Python Engineer - AI Voice Technology


Base Salary:
Up to $300,000 per annum + Equity
Location: San Francisco (Hybrid - 3 days per week in office)

We're seeking a highly skilled Founding Python Engineer to join an early-stage, well-funded AI startup in San Francisco. This company is building AI-driven voice agents that handle open-ended sales calls more effectively than human call center agents. Backed by $6M in seed funding from a top VC, they're assembling a world-class engineering team to scale their platform to millions of real-time conversations per day.

As a Founding Python Engineer, you'll work closely with the founders (ex-Google, YC alum) to design and build scalable backend systems, real-time communication infrastructure, and high-throughput APIs. This is a hands-on technical leadership role, offering the chance to shape both the product and the engineering culture at a pivotal stage.

What You'll Do:

  • Design and build scalable backend infrastructure for AI-powered voice agents.
  • Develop high-performance public APIs for partner integrations.
  • Build real-time communication systems to handle high-volume speech processing.
  • Lead and mentor junior engineers, helping grow the core team.
  • Work closely with ML, frontend, and DevOps teams to enhance AI-driven capabilities.
  • Develop integrations with CRMs, dialers, calendars, and external APIs.

Ideal Candidates Will Have:

  • Strong Python backend engineering experience, with a track record of building scalable systems.
  • Expertise in system design, real-time infrastructure, and high-QPS API development.
  • Experience in early-stage startups (Seed+ or Series A+).
  • A mindset for technical leadership, problem-solving, and ownership.

This is a rare opportunity to shape the future of AI-powered sales technology in a high-growth, well-funded startup.

Apply Now: If you're excited by the challenge of building lightning-fast, lifelike AI voice agents, we'd love to hear from you. Apply today for immediate consideration.
