Founding Senior Full Stack Engineer


About the Role

We’re supporting an early-stage AI company building a next-generation voice automation platform that powers millions of real-time conversations. As a Founding Senior Full Stack Engineer, you’ll play a key role in shaping the product’s technical foundation, owning everything from backend systems and APIs to user-facing dashboards and analytics tools.

You’ll work across the stack using React, TypeScript, and Node.js to design fast, elegant, and reliable solutions. Partnering directly with the founding team, you’ll bridge infrastructure such as prompt orchestration, telephony, and data pipelines with frontend experiences that enable customers to onboard and deploy quickly. This is a high-impact role with direct exposure to customers, rapid feedback loops, and the opportunity to define a category-leading product that’s reimagining how humans and AI communicate.


Key Responsibilities

  • Develop and ship features across the stack, including dashboards, analytics, prompt orchestration, and telephony integrations.
  • Build scalable, production-ready systems from sleek UIs to robust APIs and DevOps workflows.
  • Lead projects end to end including architecture, implementation, deployment, and iteration.
  • Design intuitive interfaces and APIs that let customers activate within hours.
  • Support onboarding and troubleshoot issues, translating user feedback into product improvements.


You Might Thrive If You

  • Have 2 years of full stack experience using React, TypeScript, Node.js, or Python.
  • Hold a degree in Computer Science or a related field, or equivalent hands-on experience.
  • Operate with a founder’s mindset, taking initiative and ownership across the stack.
  • Enjoy fast-moving, high-growth environments and learning new technologies quickly.
  • Communicate clearly and collaborate effectively within a small, dynamic team.
