  • Is consistently told has the best product in the market
  • Has paying enterprise and SMB customers
  • Has A-list investors (a16z, NEA and Sequoia)
  • Has a small founding team, including a CEO (whose first voice AI company was acquired) and a highly experienced sales, product, and marketing leads

You'll partner directly with the CEO to own the architecture, engineering strategy, and technical execution across the entire product. You'll work across the stack – from real-time voice AI systems to intuitive front-end interfaces – and help lay the foundation for the team, codebase, and culture as we grow.

What You'll Do

  • Lead engineering end-to-end (backend, frontend, infra, and DevOps)
  • Prototype and integrate voice AI pipelines
  • Make foundational decisions about architecture, infrastructure, and tooling.
  • Collaborate with the CEO to shape product roadmap and execution.
  • Build toward a system that supports high-volume hiring and tight feedback loops.
  • Establish engineering practices (testing, monitoring, CI/CD, etc.) from the ground up.
  • Help hire, onboard, and mentor the early engineering team.

What We're Looking For

  • You have 8+ years of experience building production systems
  • You care deeply not just about good code, but you also obsess about product quality and customer feedback
  • You are fluent in , React, TypeScript, and Python.
  • You've shipped and scaled real products, ideally at fast-moving startups.
  • You're excited about AI and voice interfaces, and have worked with LLMs or similar tools.
  • You're scrappy, self-directed, and love working across product and engineering.
  • You thrive in ambiguity and know how to balance shipping fast with technical debt.

Work Environment

  • Fully remote, with core collaboration hours in Pacific Time
  • Small, focused team where your work is immediately impactful
  • Momentum: real users, real feedback, real opportunity to shape what Ezra becomes
